Ingredients

(Tip: You'll find the full list of ingredients and measurements in the recipe card below.)

1 (16-ounce) box lasagna noodles
3 tablespoons extra-virgin olive oil
1 pound mushrooms, sliced
1½ teaspoon kosher salt
2 large shallots, finely diced
4 garlic cloves, grated
6 tablespoons unsalted butter
4 tablespoons flour
4 cups whole milk
¼ teaspoon nutmeg
¼ teaspoon freshly cracked black pepper, plus more for serving
4 ounces crème fraîche
1 cup finely grated Parmesan, plus more for serving
3 cups grated mozzarella
15 ounces whole-milk ricotta cheese
Fresh parsley, for serving

Directions

1. Preheat the oven to 400°F with a rack in the center position. Line a rimmed sheet pan with foil.

2. Bring a large pot of salted water to a boil over high heat. Cook the lasagna noodles until al dente according to the package directions, then drain.

3. While the noodles cook, heat 2 tablespoons of olive oil in a large skillet over medium-high heat. Add the mushrooms and ½ teaspoon of the salt. Let them cook undisturbed until they begin to brown, then continue cooking and stirring until golden brown. Transfer the mushrooms to a plate.

4. In the same skillet, heat the remaining tablespoon of olive oil over medium heat. Add the shallots and cook until softened. Stir in the garlic and cook until fragrant. Add the butter and let it melt, then sprinkle in the flour. Stir until the flour is absorbed. Slowly whisk in the milk until smooth, then add the nutmeg and black pepper. Cook until the sauce thickens. Stir in the crème fraîche and Parmesan until smooth and fully combined.

5. Spread ¼ cup of sauce in the bottom of a 9x13-inch baking dish. Add a layer of lasagna noodles, then top with one-third of the remaining sauce. Add one-third of the ricotta and spread it evenly. Sprinkle with 1 cup of mozzarella, then top with one-third of the mushrooms. Repeat the layers until all ingredients are used.

6. Cover the dish loosely with foil and place it on the prepared sheet pan. Bake for 30 minutes. Remove the foil and continue baking for 15 minutes more, until bubbly and lightly browned.

7. Remove the lasagna from the oven and let it cool for at least 5 minutes before serving. Finish with extra black pepper, Parmesan, and fresh parsley.

Servings and timing

This recipe makes 12 servings and takes about 1 hour 30 minutes from start to finish. That includes preparing the sauce and filling, boiling the noodles, assembling the layers, baking, and a short resting time before serving.

Variations

You can easily adjust this mushroom lasagna to fit your taste or what you have on hand. Try using a mix of mushrooms such as cremini, shiitake, or oyster mushrooms for deeper flavor. Spinach can be added between the layers for extra color and nutrition. For a stronger cheese flavor, swap part of the mozzarella for fontina or provolone. A little thyme or sage in the sauce can add a warm, earthy note. If you want a richer finish, drizzle a bit of truffle oil over the top just before serving.

Storage/Reheating

Store leftover mushroom lasagna tightly covered in the refrigerator for up to 4 days. For longer storage, wrap individual portions or the full dish well and freeze for up to 2 months.

To reheat from the refrigerator, place a portion in the microwave until heated through, or warm it in a 350°F oven covered with foil until hot. To reheat a larger amount, bake the covered dish in the oven until warmed through, then uncover for a few minutes if you want the top to crisp slightly. If reheating from frozen, thaw overnight in the refrigerator first for the best texture.

FAQs

Can I make mushroom lasagna ahead of time?

Yes, you can assemble it ahead of time and refrigerate it before baking. This makes it a great option for holidays, dinner parties, or busy weeknights.

What type of mushrooms work best in this recipe?

Cremini, white button, shiitake, or a combination of mushrooms all work well. Using a mix can give the lasagna more depth and complexity.

Do I need to cook the mushrooms first?

Yes, cooking the mushrooms first removes excess moisture and develops their flavor. This helps prevent the lasagna from becoming watery.

Can I use oven-ready lasagna noodles?

You can, but the texture may vary slightly depending on the brand. Regular noodles cooked until al dente give you the most reliable result.

Can I substitute the crème fraîche?

Yes, you can use sour cream or mascarpone in place of crème fraîche. Both will provide creaminess, though the flavor may be a little different.

How do I keep lasagna from falling apart when sliced?

Let it rest for at least 5 to 10 minutes after baking. This helps the layers set and makes it easier to cut neat portions.

Can I add vegetables to this lasagna?

Yes, spinach, kale, or even roasted zucchini can be added. Just make sure any extra vegetables are cooked first so they do not release too much liquid.

Is this recipe vegetarian?

Yes, this mushroom lasagna is a vegetarian main dish as written, provided the cheeses used are suitable for a vegetarian diet.

Can I freeze mushroom lasagna before baking?

Yes, you can freeze it assembled and unbaked. Wrap it tightly and thaw in the refrigerator before baking, or bake from frozen with extra time as needed.

What should I serve with mushroom lasagna?

A crisp green salad, garlic bread, or roasted vegetables pair very well with it. These sides balance the richness of the creamy, cheesy layers.
