Cook the lasagna noodles according to the package instructions until al dente. Drain well and lay them flat on a clean surface or parchment paper to prevent sticking.
In a large skillet, heat a drizzle of olive oil over medium heat. Add the minced garlic and sauté for approximately 30 seconds, until fragrant, taking care not to burn it.
Add the finely chopped mushrooms to the skillet and cook for 5-7 minutes, stirring occasionally, until the mushrooms soften and release their moisture, allowing it to evaporate.
Stir in the chopped spinach and continue to cook the mixture for an additional 2-3 minutes until the spinach has wilted. Season with Italian seasoning, salt, and pepper to taste. Remove from heat and let the mixture cool slightly.
In a large mixing bowl, combine the cooled mushroom and spinach mixture with ricotta cheese, and half of the shredded mozzarella and Parmesan cheese. Mix thoroughly until well combined.
Spread a thin layer of marinara sauce in the bottom of a 9x13-inch baking dish to prevent sticking.
Take one lasagna noodle, and along one end, place a generous portion of the filling. Carefully roll the noodle from the filled end to enclose the filling tightly. Place the roll-up seam-side down in the prepared baking dish. Repeat this process with the remaining noodles and filling, arranging the roll-ups side by side in the dish.
Once all the roll-ups are in the dish, pour the remaining marinara sauce evenly over the top. Sprinkle the remaining mozzarella and Parmesan cheese generously over the sauce.
Cover the baking dish with aluminum foil, ensuring that it does not touch the cheese to prevent sticking while baking.
Bake in the preheated oven for 25 minutes. After this time, carefully remove the foil and continue baking for an additional 10 minutes, or until the cheese is bubbly and golden brown.
Once done, remove from the oven and allow it to cool slightly before serving to set the filling.
Notes
Serve individual roll-ups on plates, garnished with fresh basil leaves and a sprinkle of extra Parmesan cheese.
