Ingredients
Lasagna Base
- 9 lasagna noodles
Vegetable Filling
- 2 tablespoons olive oil
- 1 onion, finely chopped
- 3 cloves garlic, minced
- 1 pound mushrooms (such as cremini or button), sliced
- 1/2 teaspoon dried thyme
- Salt and pepper to taste
- 2 cups fresh spinach leaves, chopped
Cheese and Sauce
- 3 cups marinara sauce
- 2 cups ricotta cheese
- 1 cup shredded mozzarella cheese
- 1/2 cup grated Parmesan cheese
Garnish
- Fresh basil leaves for garnish
Instructions
- Preheat Oven and Prepare Dish: Preheat your oven to 375°F (190°C). Grease a 9×13-inch baking dish with cooking spray or a drizzle of olive oil to prevent sticking.
- Boil Lasagna Noodles: Bring a large pot of salted water to a rolling boil. Add the lasagna noodles and cook according to package instructions until al dente. Drain and set aside.
- Sauté Onions and Garlic: Heat olive oil in a large skillet over medium heat. Add chopped onion and sauté until translucent and fragrant, about 3–4 minutes. Stir in minced garlic and cook for another minute.
- Cook Mushrooms: Add sliced mushrooms to the skillet along with dried thyme, salt, and pepper. Sauté until mushrooms are tender and their liquid has evaporated.
- Wilt Spinach: Stir in the chopped spinach and cook until wilted, about 2–3 minutes. Remove the skillet from heat and set aside the vegetable mixture.
- Layer Marinara Sauce: Spread a thin layer of marinara sauce on the bottom of the prepared baking dish to ensure flavor throughout.
- First Noodle Layer: Arrange three lasagna noodles over the sauce evenly.
- First Cheese and Vegetable Layer: Spread half of the ricotta cheese over the noodles, then spoon half the mushroom and spinach mixture evenly on top.
- Add Mozzarella and Parmesan: Sprinkle one-third of the shredded mozzarella and grated Parmesan cheeses over the vegetables.
- Repeat Layers: Repeat the layering process with three more noodles, remaining ricotta, remaining vegetable mixture, and another one-third of the shredded mozzarella and Parmesan cheeses.
- Final Layers: Finish with the remaining three noodles and spread the final marinara sauce layer on top. Sprinkle the remaining mozzarella and Parmesan cheese.
- Bake Covered: Cover the baking dish tightly with aluminum foil and bake in the preheated oven for 25 minutes.
- Bake Uncovered: Remove the foil and continue baking for an additional 10–15 minutes until the cheese is bubbly and golden brown.
- Garnish and Serve: Remove from oven and let the lasagna rest for a few minutes. Garnish with fresh basil leaves before slicing and serving.
Notes
- You can substitute cremini mushrooms with button or portobello mushrooms depending on preference.
- For a richer flavor, consider adding a pinch of nutmeg to the ricotta cheese layer.
- Use fresh spinach for best texture; frozen spinach can be used but must be thawed and drained thoroughly.
- Allow the lasagna to rest for 10 minutes before serving to set the layers for cleaner slices.
- Leftovers can be refrigerated for up to 3 days or frozen for up to 2 months.
