Italian Baked Crêpes with Ricotta and Porcini | Crespelle gratinate con ricotta e porcini

These baked crespelle combine the delicate creaminess of ricotta with the deep woodland character of porcini mushrooms. Unlike a Fontina-and-mushroom filling, this version should remain lighter and more aromatic, with ricotta providing structure rather than melted-cheese richness. The essential technical points are controlling mushroom moisture, draining the ricotta correctly and preserving recognizable pieces of porcini throughout the filling.

The Story

Porcini are among the most distinctive mushrooms in Italian cooking. Their aroma is deeper and more complex than ordinary cultivated mushrooms, combining earthy, nutty and woodland characteristics. Because of that intensity, they require relatively little manipulation. Ricotta is particularly effective because its mild dairy flavor gives the porcini enough space to remain recognizable.

Using dried porcini together with fresh mushrooms gives a more balanced result than relying exclusively on either one. Dried porcini provide concentrated aroma, while fresh cremini contribute body and texture. The soaking liquid is valuable but must be filtered extremely well and used sparingly because it frequently contains fine sediment.

Ingredients

For the crespelle

1 cup all-purpose flour (125 g)
2 large eggs
1 1/4 cups whole milk (300 ml)
2 tbsp unsalted butter, melted (28 g)
1/4 tsp fine sea salt
Unsalted butter, for the pan

For the ricotta and porcini filling

1 oz dried porcini mushrooms (28 g)
12 oz fresh cremini mushrooms (340 g)
2 tbsp extra-virgin olive oil (30 ml)
1 tbsp unsalted butter (14 g)
1 small shallot, finely chopped
1 garlic clove, lightly crushed
1/3 cup dry white wine (80 ml)
15 oz whole-milk ricotta, well drained (425 g)
3/4 cup finely grated Parmigiano Reggiano (75 g)
1 large egg
1 tsp fresh thyme leaves
Fine sea salt
Freshly ground black pepper

For the béchamel

3 tbsp unsalted butter (42 g)
3 tbsp all-purpose flour (24 g)
2 1/2 cups whole milk (600 ml)
Fine sea salt
Freshly grated nutmeg

For finishing

3/4 cup finely grated Parmigiano Reggiano (75 g)
1 tbsp unsalted butter (14 g)

Preparing the Crespelle

Whisk the eggs with the salt. Add approximately one-third of the milk, then gradually whisk in the flour until smooth. Add the remaining milk and melted butter. Rest the batter for 20–30 minutes. Heat an 8-inch nonstick skillet over medium heat and brush very lightly with butter. Pour approximately 1/4 cup batter into the center and rotate the skillet immediately to create a thin layer. Cook for 45–60 seconds on the first side and 15–20 seconds on the second. Continue until you have approximately 10–12 crespelle. Keep them pale and flexible because the final color will develop during gratination.

Preparing the Porcini

Place the dried porcini in a bowl and cover with approximately 1 cup (240 ml) warm water. Leave for 20 minutes. Lift the mushrooms from the liquid rather than pouring everything through a strainer. Filter the soaking liquid through a coffee filter, very fine sieve or several layers of cheesecloth. Reserve approximately 1/3 cup (80 ml). Gently squeeze the rehydrated porcini and chop them coarsely. Do not turn them into a paste.

Preparing the Fresh Mushrooms

Clean the cremini with a damp cloth or soft brush and slice them approximately 1/4 inch thick. Heat the olive oil and butter in a large, wide skillet over medium-high heat. Add the crushed garlic briefly, then add the mushrooms in a shallow layer, working in batches if necessary. Leave them undisturbed long enough to develop real browning. Once they have released their moisture and begun to caramelize, add the shallot and thyme. Cook for another 2–3 minutes, then add the chopped porcini.

Concentrating the Mushroom Flavor

Add the white wine and allow it to reduce completely. Add approximately 2–3 tablespoons of the filtered porcini soaking liquid and cook until this liquid has also evaporated. The objective is to transfer porcini aroma without creating a wet filling. Season with salt and freshly ground black pepper. Remove the garlic and allow the mushroom mixture to cool completely.

Preparing the Ricotta and Filling

Drain the ricotta in a fine-mesh strainer for at least 30 minutes, or several hours if particularly wet. Place it in a bowl and work it briefly until smooth. Add the completely cooled mushroom mixture, Parmigiano Reggiano and egg. Mix carefully without aggressively beating the mixture. Refrigerate for 15–20 minutes. The filling should remain creamy while holding its shape on a spoon.

Preparing the Béchamel

Melt the butter over medium-low heat. Add the flour and whisk continuously for approximately 90 seconds, keeping the roux pale. Gradually add the milk while whisking continuously. Bring gently to a simmer and cook for 5–7 minutes, until the sauce lightly coats the back of a spoon. Season with fine sea salt and a restrained amount of freshly grated nutmeg. Keep the béchamel relatively fluid.

Filling and Assembly

Place one crespella on the work surface. Add approximately 2 tablespoons of ricotta and porcini filling, about 1 teaspoon of béchamel and a small sprinkling of Parmigiano Reggiano. Fold in half and then into a triangle. Repeat with the remaining crespelle. Preheat the oven to 375°F (190°C). Butter a shallow baking dish and spread a thin layer of béchamel across the bottom. Arrange the filled crespelle slightly overlapping. Spoon the remaining béchamel lightly over the surface while leaving sections exposed. Finish with Parmigiano Reggiano and small pieces of butter. Bake for 20–25 minutes, then gratinate at 425°F (220°C) or under the broiler for 2–3 minutes. Rest 8–10 minutes before serving.

Professional Technique

Porcini require concentration rather than complication. The dried mushrooms should provide aroma, while fresh mushrooms provide physical structure. Their cooking liquid is powerful but dangerous when used carelessly. Adding a large quantity simply makes the filling wet. Reduce a very small amount directly with the mushrooms instead.

The second critical element is skillet size. Mushrooms release substantial water. If they are crowded into a small pan, the temperature falls and they steam rather than brown. A properly cooked mushroom mixture should leave the skillet almost dry.

Texture and Moisture Control

The ricotta and mushrooms must be individually dry enough before they are combined. If either component releases water, the finished filling becomes unstable. Place a spoonful of the completed filling on a plate and wait several minutes. There should be no ring of liquid around it. When baked, the center should remain creamy but should cut cleanly without running from the crespella.

Professional Mise en Place

The crespelle can be cooked several hours in advance and stacked once completely cool. The mushroom mixture can be prepared one day ahead and refrigerated after cooling. Ricotta can drain overnight. The complete filling can be prepared several hours before assembly. Béchamel can also be made in advance and reheated gently with a small quantity of milk if necessary. Assemble only when the filling is cool.

Chef Tips

Use dried porcini with a strong clean aroma. Filter the soaking liquid carefully and never pour sediment from the bottom of the bowl into the skillet. Brown fresh mushrooms in batches when necessary. Use whole-milk ricotta and freshly grated Parmigiano Reggiano. Keep garlic restrained because porcini should remain the dominant aroma. Thyme should also remain subtle. Do not add decorative herb leaves to the finished plate.

Common Mistakes

Do not soak dried porcini in boiling water. Do not use unfiltered soaking liquid. Do not overcrowd the mushroom skillet. Do not leave liquid in the pan. Do not combine hot mushrooms with ricotta. Do not use wet ricotta. Do not purée the mushroom filling. Do not make the béchamel excessively thick. Do not completely cover the crespelle with sauce. Do not skip the resting period after baking.

Wine Pairing

Barbaresco DOCG — Nebbiolo’s earthy, floral and savory characteristics connect naturally with porcini while its acidity keeps ricotta and béchamel from becoming heavy.

Barbera d’Asti DOCG — high natural acidity and moderate tannin make Barbera particularly effective with creamy mushroom preparations.

Dolcetto d’Alba — softer tannins and dark-fruit character provide a gentler Piedmontese red pairing without overwhelming ricotta.

Soave Classico — Garganega provides mineral freshness and enough structure to work with porcini while preserving the delicacy of the filling.

Verdicchio dei Castelli di Jesi — savory structure, acidity and subtle almond notes make Verdicchio one of the strongest white alternatives for mushrooms.

For this preparation, Barbaresco DOCG is my first red choice, while Verdicchio dei Castelli di Jesi is the strongest white pairing.

Storage & Reheating

The assembled crespelle can be refrigerated for up to 24 hours before baking. Cooked leftovers can be refrigerated for up to 3 days. Reheat at 325°F (165°C) until hot throughout, keeping the dish covered initially and uncovering during the final few minutes to restore the gratinated surface. The assembled dish can be frozen before baking for up to 1 month. Defrost overnight in the refrigerator before cooking.
