Story of the Dish

Porcini mushrooms has a natural place in the cooking of Trentino Alto Adige, where seasonal ingredients are often paired with butter, milk and aged cheese.

This preparation is built as a true gratin. A light béchamel connects the porcini mushrooms with Puzzone di Moena DOP, while the final layer of cheese and butter creates the roasted surface.

The finished dish should remain ingredient driven: tender and creamy inside, but with recognizable pieces beneath an irregular, deeply golden crust.

Ingredients

2 1/2 lb fresh porcini mushrooms (1.1 kg)
7 oz Puzzone di Moena DOP (200 g)
1/3 cup dry white wine (80 ml)
4 fresh thyme sprigs
3 tbsp unsalted butter (45 g)
3 tbsp all purpose flour (30 g)
2 1/2 cups whole milk (600 ml), warm
6 oz Puzzone di Moena DOP (170 g), grated or sliced
1/2 cup Parmigiano Reggiano (45 g)
2 tbsp unsalted butter (30 g), for finishing
Fine sea salt, white pepper and nutmeg, to taste

Preparation

Clean the porcini without soaking and slice them about 1/3 inch (8 mm) thick. Sauté in butter over medium high heat in batches, deglaze with white wine and reduce almost completely before assembling the gratin.

Prepare the béchamel by cooking butter and flour for 2 minutes without browning. Gradually whisk in warm milk and simmer 6 to 8 minutes until lightly thickened. Season cautiously.

Butter a wide shallow gratin dish. Add a thin layer of béchamel, arrange the porcini mushrooms, distribute Puzzone di Moena DOP between the pieces and spoon the remaining sauce lightly over and between them. Finish with Parmigiano and butter.

Bake at 400°F (205°C) for 18 to 25 minutes until bubbling. Broil 2 to 4 minutes, watching continuously, until the surface is deeply golden. Rest 8 to 10 minutes.

Professional Technique

Moisture management is the central technical point. The porcini mushrooms must enter the baking dish nearly tender but not waterlogged; otherwise liquid released in the oven will thin the béchamel and weaken the crust.

Puzzone di Moena DOP provides the regional flavor and melting character, while Parmigiano is concentrated near the surface for stronger browning. Baking integrates the dish; broiling is the separate final stage that creates the gratin.

Chef Tips

Choose the freshest, firmest porcini mushrooms available.
Keep pieces substantial enough to survive the second cooking.
Keep the béchamel relatively light because Puzzone di Moena DOP will thicken it in the oven.
Season cautiously because aged cheese adds salt as moisture evaporates.
Use a wide shallow dish and broil only at the end.

Common Mistakes

Overcooking the porcini mushrooms before assembly.
Failing to remove excess moisture from the porcini mushrooms.
Making the béchamel too thick.
Using so much cheese or sauce that the main ingredient disappears.
Skipping the final high heat gratination.
