How to Make Easy Mushroom Spinach Lasagna for a Cozy Dinner

1. Step 1: Preheat your oven to 375°F (190°C). Cook lasagna noodles according to package instructions. Drain and set aside.

3. Step 3: Add spinach to the skillet and cook until wilted. Stir in crushed tomatoes, garlic powder, Italian seasoning, red pepper flakes, salt, and pepper. Simmer for 10 minutes.
4. Step 4: Spread a thin layer of sauce in the bottom of a 9×13-inch baking dish. Arrange a layer of lasagna noodles on top of the sauce. Spread 1/3 of the ricotta cheese over the noodles, followed by 1/3 of the mozzarella cheese and 1/4 of the Parmesan cheese. Repeat with two more layers of noodles, sauce, ricotta, mozzarella, and Parmesan cheese.
5. Step 5: Cover the baking dish with foil and bake for 25 minutes. Remove the foil and bake for an additional 10-15 minutes, or until the cheese is bubbly and golden. Let the lasagna rest for 10 minutes before serving.
