Ingredients You’ll Need
For the Lasagna:
- 9 lasagna noodles
- 2 tbsp olive oil
- 1 small onion, finely chopped
- 3 cloves garlic, minced
- 10 oz (280 g) fresh spinach, chopped
- 8 oz (225 g) mushrooms, sliced
- 15 oz (425 g) ricotta cheese
- 1 large egg
- ½ cup grated Parmesan cheese
- 3 cups shredded mozzarella cheese
- ¼ tsp ground nutmeg
- ½ tsp dried basil
- ½ tsp dried oregano
- ¼ tsp salt
- ¼ tsp black pepper
- 3 cups béchamel sauce (homemade or store-bought)
Step-by-Step Instructions
- Cook the pasta
Preheat your oven to 375°F (190°C). Cook lasagna noodles according to package directions, then drain and set aside. - Prepare the veggie filling
In a large skillet, heat olive oil over medium heat. Sauté onion for 3–4 minutes until softened. Add garlic and cook for 1 minute more.
Stir in mushrooms and cook until golden and tender, about 6–7 minutes. Add spinach and cook until wilted. Season with basil, oregano, nutmeg, salt, and pepper. - Mix the cheese layer
In a medium bowl, combine ricotta, egg, and Parmesan cheese. Mix until smooth and creamy. - Assemble the lasagna
- Spread a thin layer of béchamel sauce on the bottom of a greased baking dish.
- Add 3 noodles, half the ricotta mixture, half the spinach-mushroom filling, and 1 cup mozzarella. Top with béchamel.
- Repeat layers with remaining ricotta, vegetables, mozzarella, and béchamel.
- Finish with the last 3 noodles, a final layer of béchamel, and the remaining mozzarella.
- Bake
Cover with foil and bake for 25 minutes. Remove foil and bake uncovered for another 15–20 minutes, until golden and bubbly. - Rest and serve
Let the lasagna sit for at least 10 minutes before slicing to keep the layers intact.
