Focaccia di Patate con Zucchine e Pomodorini Confit (Italian Potato Focaccia with Zucchini and Confit Cherry Tomatoes)

Italian Potato Focaccia with Zucchini and Confit Cherry Tomatoes

Story of the Dish

This Focaccia di Patate is built around three elements that must work together without competing: a soft potato enriched dough, properly prepared zucchini, and slow roasted confit cherry tomatoes.

The potato is incorporated directly into the dough. Its purpose is not to make the focaccia taste heavily of potato, but to create a crumb that is exceptionally moist, tender and elastic.

The zucchini provide freshness and a delicate vegetal sweetness, but they must be prepared correctly. Raw zucchini contain enough water to compromise the surface of a focaccia if they are simply piled onto the dough.

The cherry tomatoes require even more attention.

For this recipe, they are prepared separately and slowly roasted with extra virgin olive oil, garlic and herbs until their flavor becomes concentrated and their natural sugars intensify. They should remain succulent rather than becoming dried tomatoes.

The final focaccia should have a deeply golden and crisp bottom, a remarkably soft potato crumb, lightly caramelized zucchini and intensely flavored confit cherry tomatoes, with extra virgin olive oil connecting every element.

Ingredients

For the Potato Focaccia Dough

17.64 oz strong Italian type 0 flour

5.29 oz cooked, peeled and finely riced Russet potato

330 to 11.99 oz cool water

1.41 oz extra virgin olive oil

0.42 oz fine sea salt

0.07 oz instant dry yeast

For the Confit Cherry Tomatoes

12.35 oz ripe cherry tomatoes

2.12 oz extra virgin olive oil

2 garlic cloves, lightly crushed

3 sprigs fresh thyme

1 small sprig rosemary

0.11 oz fine sea salt

0.07 oz granulated sugar, optional depending on tomato sweetness

Freshly ground black pepper, very lightly

For the Zucchini

10.58 oz small firm zucchini

0.53 oz extra virgin olive oil

0.11 oz fine sea salt

Freshly ground black pepper, as needed

For the Pan

1.23 oz extra virgin olive oil

For Finishing

25 to 1.06 oz extra virgin olive oil

Flaky sea salt, as needed

Fresh thyme leaves, optional

A small quantity of the aromatic oil from the confit tomatoes

Part One: The Potato

Use a floury potato such as Russet.

Place the potato whole and unpeeled into cold water.

Bring gradually to a gentle simmer and cook until completely tender through the center.

Drain.

Peel while still warm.

Pass immediately through a potato ricer.

Do not use a blender or food processor.

We need a light, fluffy potato, not an elastic potato paste.

Spread the riced potato loosely on a tray and allow steam to escape for approximately 10 to 15 minutes.

Then weigh exactly:

5.29 oz cooked potato

Always weigh the potato after cooking and peeling.

Why Potato Works in Focaccia

Cooked potato introduces gelatinized starch into the dough.

Those starches are particularly effective at retaining moisture.

The result is a focaccia that feels softer and more succulent than an equivalent lean wheat dough.

But potato does not contribute gluten.

For that reason, more potato is not automatically better.

At approximately 30% of the flour weight, we obtain a significant improvement in tenderness while preserving enough wheat structure for proper fermentation and an aerated crumb.

Part Two: Preparing the Confit Cherry Tomatoes

This should be treated as a separate preparation.

Preheat the oven to:

275°F

275°F

Cut the cherry tomatoes in half lengthwise.

Arrange them cut side up in a baking dish or on a small rimmed baking sheet.

Keep them relatively close together without stacking them.

Add the lightly crushed garlic cloves.

Add thyme and rosemary.

Season with fine sea salt.

Add a very light quantity of black pepper.

If the tomatoes lack natural sweetness, distribute approximately 0.07 oz sugar over the surface.

Do not use enough sugar to make the tomatoes taste sweet.

We are balancing acidity, not making dessert.

Adding the Extra Virgin Olive Oil

Drizzle the tomatoes with approximately 2.12 oz extra virgin olive oil.

They do not need to be submerged.

The objective is slow concentration and gentle roasting rather than deep poaching.

Turn several tomatoes lightly in the oil and return them cut side up.

Slow Roasting

Place into the oven at:

275°F

275°F

for approximately:

75 to 90 minutes

Watch the tomatoes during the final 20 minutes.

They should become:

Soft

Wrinkled

Concentrated

Glossy

Slightly caramelized around the edges

Still moist inside

They should not become completely dry.

That distinction is important.

What We Want From the Confit

A good confit cherry tomato should still collapse gently when pressed.

The flavor should be dramatically more concentrated than a raw tomato.

Its acidity should become softer.

Its sweetness should become more pronounced.

The olive oil should become perfumed with tomato, garlic and herbs.

And we are keeping that oil.

It is one of the most flavorful ingredients in the entire recipe.

Cool the Tomatoes

Remove the tomatoes from the oven.

Allow them to cool completely in their aromatic oil.

Discard the rosemary and thyme stems.

Reserve the garlic if desired.

Very important:

Do not place hot confit tomatoes onto proofed focaccia dough.

They must be cool or room temperature before final assembly.

Part Three: Preparing the Zucchini

Use relatively small, firm zucchini.

Large zucchini generally contain more water and larger seeds.

Trim the ends.

Slice lengthwise approximately:

3 to 4 mm thick

A mandoline can be used, but do not make the slices paper thin.

We want zucchini that retains some texture after baking.

Removing Excess Moisture

Arrange the zucchini slices on a tray.

Season lightly with approximately 0.11 oz fine sea salt.

Allow them to stand for:

15 to 20 minutes

You will see moisture beginning to appear on the surface.

Blot thoroughly with paper towels or a clean kitchen towel.

This step significantly reduces the amount of water the zucchini releases onto the focaccia.

Lightly Searing the Zucchini

Heat a large skillet or griddle over medium high heat.

Brush the zucchini very lightly with extra virgin olive oil.

Sear for approximately:

30 to 45 seconds per side

We are not fully cooking them.

We simply want to:

Remove additional surface moisture

Begin caramelization

Develop flavor

Give the zucchini enough structure to survive the final bake

Transfer immediately to a tray.

Allow to cool completely.

Why I Prefer Pre Cooking the Zucchini

You can put raw zucchini onto focaccia.

But that creates a variable we do not need.

The zucchini release water during baking precisely when we are trying to create a beautifully browned focaccia surface.

A quick preliminary sear gives us greater control.

The zucchini will finish cooking on the focaccia.

Part Four: Preparing the Dough

Place the flour and 5.29 oz riced potato into the bowl of a stand mixer.

Mix briefly at low speed to distribute the potato.

Add the instant dry yeast.

Begin with approximately:

10.58 oz water

Reserve the remaining 30 to 1.41 oz.

Mix at low speed until the flour has absorbed the water and a rough dough forms.

Stop.

Cover.

Rest for:

20 minutes

Adding the Salt

Dissolve the 0.42 oz fine sea salt in approximately 0.71 oz of the reserved water.

Restart the mixer.

Add the salted water gradually.

Continue mixing at medium low speed until the dough begins developing elasticity.

Developing Structure

Mix for approximately 4 to 6 minutes, watching the dough carefully.

The dough should begin becoming smoother.

It should pull partially away from the sides of the bowl.

Only after you see real gluten development should you introduce the olive oil.

Adding the Extra Virgin Olive Oil

Add the 1.41 oz extra virgin olive oil gradually.

Add a little.

Allow it to disappear into the dough.

Add more.

Continue until completely incorporated.

Now evaluate the consistency.

Final Hydration Adjustment

Begin adding the remaining water a few grams at a time.

Depending on your flour and potato, you may use the full:

11.99 oz

or you may stop around:

11.64 oz

Do not chase the number.

Watch the dough.

It should be:

Soft

Elastic

Extensible

Smooth

Slightly sticky

Capable of holding structure

It should not flow like batter.

Desired Dough Temperature

The final dough should finish around:

75°F to 78°F

75°F to 79°F

Control water temperature accordingly.

This matters especially when the dough will undergo a long cold fermentation.

First Fold

Transfer the dough to a lightly oiled container.

Cover.

Rest for 20 minutes.

Wet your hands.

Stretch one side gently upward and fold toward the center.

Rotate the container.

Repeat on all four sides.

Cover.

Second Fold

After another 20 minutes, repeat.

The dough should feel noticeably stronger.

Do not stretch until it tears.

Third Fold

Wait another 20 minutes.

Perform one final gentle folding sequence.

Stop once the dough has enough strength.

More handling is not automatically better.

Beginning Fermentation

Cover.

Allow the dough to remain at room temperature for approximately:

30 to 45 minutes

It should begin showing light fermentation activity.

Do not wait for it to double.

Cold Fermentation

Refrigerate for:

18 to 24 hours

My preferred range for this focaccia is:

20 to 24 hours

The slower fermentation develops significantly better flavor while allowing us to use very little yeast.

The Following Day

Remove the dough from the refrigerator.

It should appear expanded and aerated with visible fermentation bubbles.

Allow it to stand for approximately:

30 minutes

while you prepare the pan.

Preparing the Pan

Pour approximately:

1.23 oz extra virgin olive oil

into a 13 × 18 inch metal pan.

Coat the entire bottom and sides.

A metal pan is strongly preferred because we want serious heat transfer underneath the dough.

The potato creates softness.

The pan and olive oil must provide the contrasting crispness.

Transferring the Dough

Oil your hands.

Release the dough carefully into the pan.

Do not punch it down.

Do not knead it again.

Do not use a rolling pin.

Allow it to rest untouched for approximately:

15 to 20 minutes

Stretching

Using oiled fingertips, gently stretch the dough toward the corners.

If the dough resists, stop.

Wait another 10 minutes.

Then continue.

Do not destroy fermentation gases by forcing the dough.

Final Proof

Cover loosely.

Allow the focaccia to proof for approximately:

2 to 3 hours

The exact time depends on room temperature.

The dough should become:

Puffy

Aerated

Relaxed

Visibly bubbly

Slightly jiggly when the pan is moved

This is when we are ready to assemble.

Part Five: Final Assembly

Preheat the oven thoroughly to:

450°F

446°F

Oil your fingertips.

Dimple the focaccia deeply but gently.

Press almost to the bottom of the pan.

Lift your fingers vertically.

Do not drag them across the surface.

The surrounding dough should remain aerated.

Arranging the Zucchini

Place the cooled zucchini across the surface.

Do not completely cover the dough.

Leave exposed areas where the focaccia can brown.

Fold or curve some zucchini slices naturally rather than arranging everything with geometric perfection.

The presentation should feel elegant but organic.

Adding the Confit Cherry Tomatoes

Drain the tomatoes lightly, reserving their aromatic oil.

Distribute the confit tomatoes between the zucchini.

Press them very gently into the dough.

Do not bury them.

Some should remain largely exposed so their edges can caramelize further during baking.

Do Not Overload the Focaccia

This is critical.

The temptation with a vegetable focaccia is to cover every centimeter.

Do not.

Too many toppings produce:

Excess moisture

Poor oven spring

Dense areas

Weak browning

A soggy center

The focaccia must remain bread first.

The zucchini and tomatoes should complement it.

The Confit Oil

Take approximately:

15 to 0.71 oz of the reserved tomato confit oil

and drizzle it lightly across the focaccia.

This oil contains flavor from:

Tomato

Garlic

Thyme

Rosemary

Extra virgin olive oil

Use it intelligently.

Do not flood the dough.

Final Seasoning

Add a small quantity of flaky sea salt.

Add a few fresh thyme leaves if desired.

Finish with a very light additional drizzle of extra virgin olive oil.

No cheese is necessary.

No balsamic glaze.

No decorative sauce.

No unnecessary garnish.

Let the ingredients speak.

Baking

Place the pan on the lower middle rack.

Bake at:

450°F

446°F

for approximately:

23 to 28 minutes

Rotate once if necessary.

The finished focaccia should show substantial coloration.

What to Look for During Baking

The exposed dough should become deeply golden.

The zucchini should develop light caramelization around the edges.

The confit tomatoes should darken slightly without burning.

The perimeter should become crisp.

The bottom should fry gently against the olive oil and hot metal.

The interior should continue expanding around the vegetables.

Internal Temperature

The thickest section of bread should reach approximately:

200°F to 205°F

199°F to 205°F

Do not insert the thermometer through a tomato or zucchini.

Measure the bread itself.

Checking the Bottom

Lift one edge with a thin metal spatula.

The bottom should be:

Deep golden brown

Crisp

Firm

Evenly baked

Slightly fried in appearance

If the top is ready but the bottom remains pale, place the pan on the lowest oven rack for another 3 to 5 minutes.

A focaccia this moist needs a properly developed bottom crust.

Immediately After Baking

Remove from the oven.

Allow the focaccia to remain in the pan for approximately:

3 to 4 minutes

Then drizzle extremely lightly with the reserved confit tomato oil.

Transfer carefully to a wire rack.

Do not leave the focaccia cooling inside the pan.

Trapped steam will soften the bottom.

Resting

Allow the focaccia to rest for at least:

20 to 25 minutes

before cutting.

This is particularly important here because we have three significant sources of moisture:

Potato

Zucchini

Tomato

The crumb needs time to stabilize.

The Correct Crumb

Cut through a section without a large tomato directly on top.

The interior should be:

Extremely soft

Moist

Elastic

Light

Irregularly aerated

Tender

The potato should be almost invisible.

You should not see mashed potato streaks or lumps.

Its effect should be primarily textural.

The Correct Surface

Now cut through a section containing both zucchini and tomato.

You should experience several layers of texture.

First, the lightly caramelized vegetables.

Then the tender upper crumb that has absorbed a small amount of tomato and herb oil.

Then the moist potato enriched interior.

Finally, the crisp bottom.

That contrast is what makes this focaccia gastronomically interesting.

Mistakes to Avoid

Using Leftover Mashed Potatoes

Butter, milk and unknown moisture destroy control over the formula.

Blending the Potato

This can produce a gluey texture.

Use a potato ricer.

Using Very Large Zucchini

They generally contain excessive moisture.

Putting Wet Raw Zucchini Directly on the Dough

The surface can become watery.

Salt, dry and lightly sear them first.

Calling Raw Tomatoes Confit

Confit tomatoes require a separate slow cooking process.

Drying the Tomatoes Completely

They should remain succulent.

Putting Hot Tomatoes on the Dough

Cool them first.

Throwing Away the Confit Oil

That aromatic oil is valuable.

Using Too Much Confit Oil

Valuable does not mean unlimited.

Overloading the Surface

The focaccia needs exposed dough to expand and brown.

Adding Too Many Additional Flavors

Garlic, herbs, zucchini and concentrated tomato already provide substantial complexity.

Underbaking

The potato and vegetables create considerable moisture.

Develop the crust properly.

Cutting Immediately

Allow the crumb to stabilize.

Why This Focaccia Stays Soft

The potato is largely responsible.

Its cooked starches retain moisture within the crumb.

Extra virgin olive oil contributes tenderness.

The long fermentation develops flavor without requiring excessive yeast.

Together, they produce a focaccia that remains remarkably pleasant even after cooling.

Chef Gianluca’s Recommendation

This focaccia depends on moisture management.

That is the technical key to the entire recipe.

The potato contains water.

The zucchini contains water.

The tomatoes contain water.

If all three ingredients enter the focaccia without control, the result may be soft, but it will not be properly baked.

So treat each ingredient differently.

The potato should be boiled, riced and allowed to release steam.

The zucchini should be salted, dried and briefly seared.

The cherry tomatoes should be slowly roasted until their flavor becomes concentrated and part of their water has evaporated.

Only then do the three elements come together.

And when you assemble the focaccia, do not cover every centimeter.

I want to see the dough.

I want areas where the crust can rise and become deeply golden between the zucchini and tomatoes.

After baking, use a little of that extraordinary tomato confit oil.

A little.

That oil has already absorbed tomato, garlic and herbs. It does not need to drown the focaccia to make itself understood.

Then wait before cutting.

When you finally cut through the bread, look at the layers.

The top should have concentrated tomato, lightly caramelized zucchini and aromatic olive oil.

The center should re

Wine Pairing

Vermentino

A dry Vermentino is particularly successful here.

Its acidity provides freshness against the olive oil and potato, while its Mediterranean aromatic character complements zucchini and herbs.

Serve at approximately:

46°F to 50°F

46°F to 50°F

Falanghina

A fresh Falanghina is another excellent option.

Its acidity and restrained fruit work beautifully with the sweetness and acidity of the confit tomatoes without overwhelming the zucchini.

Chef's Notes

Use a floury potato.

Cook the potato specifically for the focaccia.

Weigh it after cooking and peeling.

Rice it while warm.

Allow steam to escape.

Hold back part of the dough water.

Use small, firm zucchini.

Salt the zucchini before cooking.

Dry thoroughly.

Sear only briefly.

Prepare the tomatoes separately.

Cook the tomatoes slowly.

Keep them succulent.

Save their aromatic oil.

Cool all toppings before they touch the dough.

Ferment the dough slowly.

Do not punch down after fermentation.

Use a metal pan.

Proof until the dough becomes visibly aerated and jiggly.

Dimple gently.

Do not overload the surface.

Use the confit oil with restraint.

Bake until the bottom is genuinely crisp.

Rest before cutting.

Professional Dough Formula

Baker's Percentages

Strong type 0 flour: 100%

Cooked potato: 30%

Added water: 66 to 68%

Extra virgin olive oil: 8%

Fine sea salt: 2.4%

Instant dry yeast: 0.4%

Remember that the effective hydration is higher than the percentage suggests because cooked potato contains substantial water.

Storage and Reheating

This focaccia is best on the day it is baked because of the vegetable toppings.

Once completely cool, store tightly wrapped at room temperature for approximately:

1 day

For longer storage, freeze it.

I do not recommend keeping it for several days at room temperature because the vegetables increase surface moisture.

Freezing

Cut the completely cooled focaccia into individual portions.

Wrap carefully.

Freeze.

For best quality, freeze on the day of baking.

Regeneration

Thaw completely.

Place on a preheated baking sheet or directly on the oven rack.

Reheat at:

375°F

374°F

for approximately:

7 to 9 minutes

The objective is to restore the crisp bottom without drying the potato crumb.

Serving

Serve slightly warm or at room temperature.

Cut into rectangular portions for an antipasto or aperitivo.

For restaurant presentation, cut into smaller precise portions and finish each piece with one drop or a very thin brush of the reserved tomato confit oil.

Do not soak it.

The oil should provide aroma.
