How to Make Mushroom Lasagna

There’s no need to be intimidated! This mushroom lasagna recipe is actually so easy to make. I’ll guide you through every step with helpful pictures and clear instructions. Let’s get to cooking!

Mushrooms

Prep and Cook Pasta: Preheat oven to 375ºF. Spray a 9x13x2-inch baking dish with cooking spray and set aside. Boil lasagna noodles according to the package directions. Then, drain them in cold water and set them aside.
Add: In a large pot, melt the butter over medium-high heat. Add the mushroom slices, shallots, garlic, Italian seasoning, salt, and pepper. Stir to combine.
Sauté: Cook the mushrooms, stirring occasionally, until they are tender, about 5 minutes. Remove the mushrooms from the pot and set aside.

Béchamel Sauce

Combine: Return to the same pot and melt the ¼ cup of butter over medium-high heat. Whisk the flour into the butter to create a paste.
White Sauce: Slowly pour and whisk the milk into the butter paste. A thick sauce should form.
Add: Whisk the Italian seasoning, garlic powder, onion powder, and salt and pepper to taste, then remove the sauce from the heat.

Assemble Mushroom Lasagna

Layer: Spread about ½ cup of the sauce at the bottom of the prepared baking dish, then add a layer of noodles on top of the sauce. Spread ⅓ of the ricotta mixture over the noodles, followed by ⅓ of the cooked mushrooms, then the sauce on the mushrooms.
Add: Sprinkle 1 cup of mozzarella cheese over the top of the sauce. Repeat the layers two more times, ending with the mozzarella cheese on top.
Bake: Cover the dish in foil and bake for 20 minutes. Then, remove the foil and bake for an additional 20-25 minutes or until it is heated through and the cheese is bubbly. Remove the lasagna from the oven, and let it rest a few minutes before serving! Garnish with fresh parsley or basil.

Mushroom Lasagna Variations to Try

This mushroom lasagna is customizable! Here are my tips to make it with meat or use oven ready noodles.

Can I add some kind of protein? If you want to add meat to this lasagna, I recommend trying Italian sausage. I would cook the sausage and mix it with the cooked mushrooms before putting the dish together.
Can I Use Oven-Ready Noodles? You can use oven-ready lasagna noodles with this recipe. When making the béchamel, double the sauce. You will also need to cook the lasagna for longer until the noodles are soft. Keep the lasagna covered while the noodles cook. Once they are ready remove the foil to brown the cheese on top.

How to Store Leftovers

If you’re a fan of leftovers like I am, you’re going to love having extra mushroom lasagna. It tastes just as wonderful the next day, making it the perfect meal to enjoy throughout the week!

In the Refrigerator: Store in an airtight container in the fridge for up to 5 days.
In the Freezer: Store in the freezer in an airtight container for up to 2 months. I recommend storing the leftovers in individual portions for easier reheating.
To Reheat: Reheat in the microwave or oven at 350ºF until the center is warmed.
