Wild Mushroom Lasagne

This wild mushroom lasagne is a sophisticated vegetarian alternative to the classic ragu-based dish. By combining intense dried porcini mushrooms with a rich tomato sauce and a silky, garlic-infused béchamel, you create layers of deep, savoury flavour. The earthiness of the mushrooms provides a meaty texture that makes this dish feel truly indulgent, while the golden Parmesan crust adds a satisfying crunch to every bite.

Ideal for a comforting weekend dinner or a celebratory vegetarian main course, this recipe showcases how simple pantry staples like dried mushrooms and tinned tomatoes can be transformed into an elegant meal. Serve it alongside a crisp green salad or some buttery garlic bread to balance the richness. It is a wonderful option for home cooks looking to master the art of a proper homemade lasagne.

How to make Wild Mushroom Lasagne

Heat butter in a 2-quart heavy saucepan over moderately low heat until melted, then add flour and cook roux over low heat, whisking, 3 minutes. Add hot milk in a fast stream, whisking vigorously, and whisk in garlic and salt. Bring to a boil, whisking. Reduce heat and simmer, whisking occasionally, 10 minutes, then remove garlic and add pepper.

Pour boiling-hot water over porcini in a bowl and let stand until softened, about 20 minutes.Lift out porcini, squeezing excess liquid back into bowl, then rinse to remove any grit. Pour soaking liquid through a sieve lined with a dampened paper towel into another bowl. Chop porcini and add to soaking liquid.

Cook onion in oil in a 12-inch heavy skillet over moderate heat, stirring occasionally, until softened, 4 to 5 minutes, then stir in tomatoes with juice, sugar, porcini with soaking liquid, and 1 tablespoon basil. Simmer, stirring frequently, until tomatoes have broken down into a chunky sauce, about 25 minutes. Stir in salt and remaining tablespoon basil.

Cook lasagne noodles in a 6- to 8-quart pot of boiling salted water 8 minutes (noodles will not be cooked through), then drain and transfer to a bowl of cold water.

Put oven rack in middle position and preheat oven to 218°C.

Spread 230g béchamel on bottom of a buttered 13- by 9-inch baking dish, reserving remainder for last layer. Drain 3 lasagne noodles in 1 layer on a kitchen towel and arrange over béchamel in baking dish. Spread pasta in dish evenly with one third of mushroom tomato sauce and sprinkle with 40g cheese. Repeat layering of pasta, mushroom tomato sauce, and cheese twice, then cover with last 3 lasagne noodles. Spread remaining béchamel on top and sprinkle with remaining 90g cheese.

Bake, uncovered, until lasagne is bubbling and top is browned, 30 to 35 minutes. Let stand at room temperature at least 15 minutes before cutting.
