Crafting Mushroom and Spinach Lasagna Rolls can be fun and rewarding. Follow these steps for amazing results:

1. Preheat the Oven: Begin by preheating your oven to 375°F (190°C). This ensures it’s ready for baking the rolls.
2. Cook the Noodles: Boil the lasagna noodles according to package instructions until al dente. Drain and lay them flat on a clean kitchen towel.
3. Sauté the Vegetables: In a pan, heat the olive oil over medium heat. Add the minced garlic and sliced mushrooms, and sauté until the mushrooms are tender. Add the chopped spinach and cook until wilted. Season with salt, pepper, and Italian seasoning if using. Remove from heat.
4. Mix the Filling: In a large bowl, combine the ricotta cheese, 1 cup of mozzarella cheese, Parmesan cheese, and the beaten egg. Stir in the sautéed vegetable mixture until evenly combined.
5. Prepare the Baking Dish: Spread a thin layer of marinara sauce on the bottom of a 9×13-inch baking dish.
6. Assemble the Rolls: Take a lasagna noodle and spread about 2-3 tablespoons of the filling mixture along one end. Carefully roll it up and place seam-side down in the baking dish. Repeat with remaining noodles and filling.
7. Add Sauce and Cheese: Pour the remaining marinara sauce over the top of the rolls. Sprinkle additional mozzarella cheese on top.
8. Cover and Bake: Cover the baking dish with aluminum foil and bake in the preheated oven for 25 minutes. Then, remove the foil and bake for an additional 10-15 minutes, until the cheese is bubbly and golden.
9. Cool: Once out of the oven, let the rolls cool for 10-15 minutes. This makes serving easier and allows the flavors to settle.
10. Serve: Cut into sections and serve warm. Enjoy the tasty Mushroom and Spinach Lasagna Rolls!
