Italian Spaghetti with Zucchini, Provolone del Monaco & Basil

Story of the Dish

Spaghetti alla Nerano is one of those Italian dishes that proves how a few humble ingredients can become something extraordinary when technique is handled correctly. Zucchini, pasta, cheese, basil, and olive oil sound almost too simple. Yet when the zucchini is properly fried, rested, and emulsified with pasta water and Provolone del Monaco, the result is intensely savory, creamy, aromatic, and unmistakably Campanian.

The key is important: this is not spaghetti with zucchini and melted cheese. The sauce is created through emulsification. There should be no cream, no butter, and no heavy cheese sauce. The finished spaghetti should be glossy and fluid, with the zucchini almost dissolving around the pasta.

History and Origins

Spaghetti alla Nerano comes from Nerano, a small fishing village on the Sorrento Peninsula in Campania, overlooking the Gulf of Salerno and close to the Amalfi Coast.

The dish is generally associated with Maria Grazia, the historic restaurant in Marina del Cantone, where it is said to have been created in the early 1950s. Its apparent simplicity eventually made it one of the most recognizable pasta dishes of the Sorrento Peninsula.

The defining ingredient, beyond the zucchini, is traditionally Provolone del Monaco DOP, an aged cow's-milk cheese produced in the Lattari Mountains. Its sharp, savory and slightly spicy character gives Nerano much more depth than a simple zucchini pasta.

Over the years, chefs have developed different interpretations of the technique. Some fry the zucchini shortly before service; others allow it to rest so that its texture softens and its flavor becomes deeper. Some use only Provolone del Monaco, while others balance it with Parmigiano Reggiano.

For a top-quality version, the objective remains the same: concentrated zucchini flavor, controlled cheese, abundant basil aroma, and a perfectly stable pasta-water emulsion.

Ingredients

For the Fried Zucchini

1½ lb small to medium zucchini

Extra-virgin olive oil, as needed for frying

Fine sea salt, to taste

For the Pasta

14 oz spaghetti

5 oz Provolone del Monaco DOP, finely grated

1 oz Parmigiano Reggiano, finely grated

1 large handful fresh basil leaves

Freshly ground black pepper, to taste

Fine sea salt, for the pasta water

About 1½ cups reserved pasta cooking water, as needed

2 tablespoons extra-virgin olive oil, preferably from Campania

Preparation

1. Choose the Right Zucchini

Use relatively small, firm zucchini with smooth skin and very few developed seeds.

Large watery zucchini will dilute the flavor and tend to become mushy rather than creamy.

Wash and dry them thoroughly.

Slice into thin rounds approximately ⅛ inch thick. Keeping the slices reasonably consistent is important because they need to fry at approximately the same rate.

2. Fry the Zucchini

Heat about ¾ inch of extra-virgin olive oil in a wide pan to approximately 340–350°F.

Fry the zucchini in small batches.

Do not overcrowd the pan.

The zucchini should become golden around the edges while remaining slightly softer toward the center. You are looking for concentrated sweetness and nuttiness rather than dark, crisp zucchini chips.

Transfer each batch to a tray lined with absorbent paper.

Season very lightly with salt while still warm.

Continue until all the zucchini has been fried.

3. Let the Zucchini Rest

This is one of the most important details of a serious Nerano.

Place the fried zucchini in a bowl with several torn basil leaves. Cover and allow it to rest for at least 1 hour, preferably 2.

As the zucchini rests, it softens and its fried exterior absorbs some of its own moisture. This transformation helps it later break down into the characteristic creamy Nerano sauce.

For even deeper flavor, the fried zucchini can be prepared several hours ahead and refrigerated. Bring it closer to room temperature before finishing the pasta.

4. Prepare the Cheese

Finely grate the Provolone del Monaco and Parmigiano Reggiano.

The cheese needs to be very fine because large shavings melt unevenly and dramatically increase the risk of clumping.

Keep the cheese at room temperature while the pasta cooks.

This matters.

Cold cheese introduced directly into very hot pasta can seize rather than emulsify.

5. Cook the Spaghetti

Bring a large pot of water to a boil.

Salt the water, but more lightly than you would for many other pasta dishes. Provolone del Monaco is already quite savory.

Cook the spaghetti until approximately 3 minutes before al dente.

Before draining, reserve at least 2 cups of pasta water.

The starch in this water is essential. It is not merely added for moisture—it is one of the structural components of the sauce.

6. Reawaken the Zucchini

Place approximately three-quarters of the fried zucchini in a large sauté pan.

Add about ½ cup hot pasta water.

Bring to a gentle simmer.

Using the back of a wooden spoon, lightly crush some of the zucchini.

Do not purée it.

You want three textures simultaneously: zucchini that has nearly dissolved, soft pieces incorporated into the sauce, and recognizable golden rounds.

Add the remaining zucchini.

7. Finish the Spaghetti in the Pan

Transfer the undercooked spaghetti directly into the zucchini pan.

Add another small ladle of pasta water.

Cook over medium heat while continuously tossing or stirring the spaghetti.

The starch released from the pasta will begin binding the zucchini, olive oil and cooking water.

Continue adding pasta water a little at a time.

Do not flood the pan.

After approximately 2 minutes, the spaghetti should be nearly al dente and surrounded by a loose, glossy zucchini emulsion.

Now remove the pan from the heat.

This next step determines whether the Nerano becomes beautifully creamy or turns into a mass of stringy cheese.

8. Mantecatura — The Critical Step

Allow the pan to sit off the heat for approximately 20–30 seconds.

Add a small splash of pasta water.

Begin adding the grated Provolone del Monaco gradually while vigorously tossing the spaghetti.

Add the Parmigiano.

Continue tossing.

Add a little more pasta water whenever necessary.

The cheese should emulsify into the zucchini and starch, not simply melt onto the spaghetti.

You are creating a suspension of cheese, starch, water and fat.

The finished sauce should look almost impossibly creamy even though there is no cream.

Add the remaining basil, tearing the leaves by hand immediately before incorporating them.

Finish with freshly ground black pepper and a small drizzle of excellent extra-virgin olive oil.

Taste before adding additional salt.

Understanding the Nerano Emulsion

The technical heart of Spaghetti alla Nerano is temperature control.

Cheese contains proteins and fat. When aged cheese encounters excessive heat, the proteins contract and the fat separates. Instead of producing a sauce, you get strings or lumps of cheese surrounded by oil.

That's why the final cheese addition should happen off direct heat.

Meanwhile, pasta water provides starch. The starch helps stabilize water and fat while the physical action of tossing distributes microscopic droplets throughout the sauce.

The softened zucchini contributes additional body.

This combination creates Nerano's famous creamy texture without requiring cream.

Professional Technique

Salt the cooking water correctly, reserve starchy pasta water, and finish the pasta in the sauce whenever the recipe allows. Fresh pasta requires gentler handling and much shorter cooking than dried pasta. The sauce should coat the pasta rather than pool beneath it, and final seasoning should be adjusted only after cheese, cured meat, or other salty components are incorporated.

Chef Tips

Fry the zucchini—don't sauté it

Traditional Nerano gets much of its characteristic flavor from fried zucchini. Simply sautéing zucchini produces a completely different flavor profile.

Don't burn the zucchini

Deep brown zucchini becomes bitter and dominates the delicate sauce. Aim for golden edges and a tender center.

Rest the zucchini

Freshly fried zucchini is good. Rested fried zucchini is better for Nerano because it becomes softer, richer and easier to incorporate into the sauce.

Use real Provolone del Monaco when possible

Its flavor is central to the identity of the dish: savory, slightly sharp, buttery and mildly spicy as it ages.

If it is unavailable in the United States, use a high-quality aged provolone with a controlled amount of Parmigiano Reggiano, understanding that the flavor will not be identical.

Keep the sauce looser than you think

Pasta continues absorbing moisture between the pan and the table.

When the spaghetti leaves the pan, the sauce should be slightly more fluid than the final consistency you want.

Mistakes to Avoid

Adding cream

Cream is unnecessary and changes the identity of the dish. Proper Nerano gets its creaminess from zucchini, starch, cheese and emulsification.

Adding too much cheese

Nerano should taste primarily of zucchini. The Provolone del Monaco reinforces and deepens the zucchini rather than burying it.

Using garlic as the dominant flavor

Garlic appears in some modern versions, but a strong garlic flavor can overwhelm the sweet fried zucchini and aged cheese. For this version, I leave it out completely.

Cooking the cheese over high heat

This is the fastest way to produce a greasy, stringy sauce.

Over-salting the pasta water

Remember that aged Provolone del Monaco contributes substantial salinity.

Blending all the zucchini

A completely smooth zucchini purée loses the textural character that makes a beautiful Nerano interesting.

Serving and Presentation

Serve immediately.

Twirl the spaghetti into a controlled nest in the center of a warm shallow bowl.

Allow several golden zucchini rounds to remain visible naturally throughout the pasta rather than decorating the plate artificially.

Spoon a small amount of the zucchini emulsion around and through the spaghetti.

Finish with a few small fresh basil leaves and a restrained drizzle of excellent extra-virgin olive oil.

The final plate should be glossy, creamy and natural, not overloaded with grated cheese or unnecessary garnish.

The zucchini should remain visually recognizable.

Chef Gianluca’s Recommendation

The secret to exceptional Spaghetti alla Nerano isn't adding ingredients—it's knowing when to stop adding them.

Use excellent zucchini, fry them correctly, give them time to rest, cook the spaghetti aggressively in the zucchini water, and perform the final mantecatura away from direct heat.

When you pick up the spaghetti with a fork, the sauce should cling naturally to every strand. There should be no pool of oil and no visible mass of melted cheese.

That is when Nerano becomes what it is supposed to be: a simple Campanian pasta transformed by technique.

Wine Pairing

A Falanghina del Sannio is an excellent pairing.

Its freshness and mineral character cut through the fried zucchini and aged cheese while its aromatic profile complements the basil.

A Greco di Tufo works beautifully when you want more structure and minerality.

For something particularly regional, a chilled Costa d'Amalfi Bianco creates an elegant Campanian pairing.

Avoid heavily oaked white wines. Nerano benefits from acidity, freshness and minerality rather than excessive weight.
