Mixed Mushroom Lasagna Recipe

Lasagna is a labor of love. Not only do you have to cook the noodles and make a filling, you also need to whisk together a béchamel and shred several different kinds of cheese. After all that prep, you still have to build and bake the lasagna. So why pour all of this time and effort into a pasta dish? Because it's the best thing you'll ever eat.

That might be an exaggeration, especially if you've been somewhere like Italy and have eaten hand-crafted pasta deep in the rolling hills of Tuscany (that's hard to beat, to be fair). However, as far as home cooking goes, this white lasagna shared by developer Michelle McGlinn is a showstopper packed with flavor, texture, and cheese. So much cheese.

This creamy mixed mushroom lasagna is the perfect vegetarian entrée. Using a flavorful mix of cremini, porcini, and chanterelle mushrooms, the filling is bursting with umami that pairs perfectly with the creamy thyme béchamel and seasoned ricotta. Melty, gooey mozzarella and fontina cheeses then fold between each layer to make an irresistibly decadent lasagna. Sold yet? Told you it was worth the effort.

Everything you need to make mixed mushroom lasagna

For the mushroom filling, you'll need olive oil, garlic, salt and pepper, parsley, and a variety of mushrooms. We recommend using cremini, chanterelle, and porcini, which pair best with cream and thyme, but any mix of mushrooms will work and we encourage you to use what's available in your market. Whichever variety you pick should equal a total of 1 pound (1 ounce of dried mushrooms is about 8 ounces rehydrated).

From there, you'll need cooked lasagna noodles, butter, shallot, flour, milk, fresh thyme, ricotta, mozzarella cheese, and fontina cheese. You can use dried thyme instead of fresh if preferred. For the cheeses, McGlinn recommends buying shredded mozzarella (as opposed to the ball in water) and fontina you can grate or shred rather than the packaged snacking cubes. Not only will the shredded cheeses be easier to build with, but they will melt faster for a more gooey, creamy result.

Prep the noodles

To avoid slathering the cooked pasta in oil, which will cause the fillings to slide around, instead lay each piece of pasta flat on a baking sheet. Shingle the pieces so they aren't directly on top of each other, then cover them with a towel to retain the moisture. When ready to use, carefully pull each strip from the pile to avoid ripping any noodles. McGlinn's tip? Cook a few extra, just in case.

Cook the filling

Once you've rehydrated and chopped all of the mushrooms (we recommend saving the water you used to rehydrate them for dishes like risotto), heat some oil in a skillet and brown them until glossy and dark. The mushrooms will soften and caramelize in the heat. Add the garlic, salt, and pepper and cook until fragrant, then sprinkle with parsley and remove from the heat.

Whisk together a béchamel

Béchamel sounds intimidating, but it's as simple as whisking together cooked flour and milk. Sauté the shallots in butter until soft, then sprinkle in the flour. The flour will turn into a brownish paste, which you'll want to whisk constantly to avoid burning. The paste forms in a matter of seconds, so don't walk away — whisk until just browned and clumpy, then start adding the milk. Add the milk slowly while whisking to smooth the clumped flour, then cook for a few minutes to thicken into a gravy. The consistency should be similar to glue. If it gets too thick, just splash in a little more milk. Season with salt, pepper, and thyme.

Building the lasagna

To remember which layers go where, write a quick mnemonic blueprint to follow before beginning the lasagna. Our recommended layering order looks like this: B,N,R,M,C,B, or béchamel, noodles, ricotta, mushrooms, cheese, béchamel. Spread a thin layer of béchamel on the bottom of the baking dish, then layer with three lasagna noodles. Spread about half the ricotta onto the noodles (or dollop spoonfuls into the dish), then layer with the prepared mushroom mixture. Sprinkle with cheese and be generous, if you can, but remember you need this cheese two more times. Then, drizzle another layer of béchamel over the cheese. The order isn't vital to get right, but try to remember that the béchamel acts as a glue to the noodles and should always go underneath them.

Baking and serving the lasagna

Once you've filled all the layers of the lasagna and trimmed the sides, place the casserole in the oven and bake until the cheese on top is melted and browning. Let the lasagna rest for 10 to 15 minutes after baking to make it easier to cut into. If you serve it immediately, the gooey, warm cheese will slide around and cause messy slices.

This lasagna is as rich as it is flavorful and is best served with simple, vegetable-heavy sides like broccoli salad, roasted eggplant, or sautéed spinach. To satisfy the meat-eaters in your family, serve after a charcuterie board or alongside grilled sausages; but promise, even the carnivores will enjoy this meatless Monday dinner.

Prep Time
Cook Time
slice of lasagna on a plate
Total time: 1 hour, 10 minutes
  • 2 tablespoons olive oil
  • 1 ounce dried porcini mushrooms, rehydrated, chopped
  • 3 ½ ounces chanterelle mushrooms, chopped
  • 5 ounces cremini mushrooms, chopped
  • 4 cloves garlic, minced
  • Salt and pepper
  • ¼ cup finely chopped parsley
  • 12 lasagna noodles, boiled to al dente
  • 4 tablespoons butter
  • 1 medium shallot, finely diced
  • ¼ cup flour
  • 2 cups milk
  • 2 tablespoons fresh thyme, plus more for topping
  • 3 cups ricotta
  • 4 cups shredded mozzarella cheese
  • 3 cups shredded fontina cheese
  1. Preheat the oven to 400 F.
  2. Arrange cooked lasagna noodles flat on a baking sheet and cover them with a towel to prevent sticking or drying out.
  3. Heat oil in a skillet over medium heat and add the mushrooms. Cook until mushrooms are browned and softened, about 5 minutes. Add the garlic and cook until fragrant, about 1 to 2 minutes longer. Season with a pinch of salt and pepper, then stir in the parsley and remove from the heat.
  4. To make the béchamel sauce, melt the butter in a separate skillet over medium heat. Add the shallots and cook until softened, about 2 to 3 minutes. Add the flour and whisk until a light brown paste forms. Then slowly whisk in the milk, combining it with the paste until smooth. Bring to a simmer and cook until thick, stirring often, about 5 to 10 minutes. Once thick, add a pinch of salt and pepper and the thyme and stir.
  5. Season ricotta with a pinch of salt and pepper. Combine fontina and mozzarella in a bowl.
  6. Spread a thin layer of béchamel sauce onto the bottom of a 9 x 13-inch casserole dish. Layer 3 noodles on top of the sauce side by side, overlapping slightly. Spread half the ricotta onto the noodles, then spread half of the mushroom mixture onto the ricotta. Sprinkle ⅓ of the shredded cheese mixture over mushrooms, then layer with another thin layer of béchamel.
  7. Repeat the layering order again, starting with the noodles. Layer 3 noodles on top of béchamel, then cover in ricotta, mushrooms, shredded cheese, and béchamel. Top with 3 more lasagna noodles (If none broke, you will have 3 extra noodles).
  8. Top the noodles with any remaining béchamel and the remaining shredded cheese. Trim any noodles that hang over the sides, then put in the oven and bake for 30 minutes, or until the cheese on top is melted and beginning to brown.
  9. Remove the lasagna from the oven and sprinkle with thyme to serve. For best serving results, allow lasagna to cool for 10 to 15 minutes before slicing.
