Instructions
Preheat your oven to 375°F (190°C).
Cook the lasagna noodles according to the package instructions until they are al dente. Drain thoroughly and set them aside, ensuring they don't stick together.
In a large skillet, heat the olive oil over medium heat. Once hot, add the finely diced onion and sauté for about 5 minutes, or until it becomes translucent and fragrant.
Next, add the minced garlic and sliced mushrooms to the skillet. Cook for about 5-7 minutes, stirring occasionally, until the mushrooms are tender and any liquid they release has evaporated.
Toss in the chopped spinach, dried oregano, dried basil, and season with salt and freshly cracked black pepper. Continue to cook for another 2-3 minutes until the spinach has wilted and brightened in color. Remove the skillet from heat and allow it to cool slightly.
In a separate mixing bowl, combine the ricotta cheese, cottage cheese, and half of the grated mozzarella cheese. Mix until smooth and well incorporated.
Begin assembling the lasagna by spreading a thin layer of marinara sauce at the bottom of a 9x13 inch baking dish to prevent sticking.
Lay 3 lasagna noodles side by side over the sauce. Spread half of the ricotta cheese mixture evenly over the noodles, followed by half of the mushroom-spinach mixture.
Drizzle a third of the marinara sauce over the mushroom layer to enhance moisture and flavor. Repeat this layering process once more—3 noodles, half the ricotta mixture, half the mushroom-spinach mixture, and another drizzle of marinara sauce.
For the final layer, place the remaining 3 noodles on top. Spread the leftover marinara sauce evenly over them, then generously sprinkle the remaining mozzarella cheese and all of the Parmesan cheese on top.
Cover the baking dish with aluminum foil, using cooking spray on the underside of the foil to prevent sticking. Bake in the preheated oven for 25 minutes to allow the flavors to meld.
Carefully remove the foil and continue baking for an additional 15 minutes, or until the top is golden brown and bubbly.
Once baked, let the lasagna cool for about 10 minutes before slicing into squares and serving.
Notes
Serve hot, garnished with fresh basil or parsley. Pair with a side salad and garlic bread.
