Making Mushroom and Spinach Lasagna Rolls is straightforward if you follow these easy-to-understand steps:

1. Preheat the Oven: Preheat your oven to 375°F (190°C).

2. Cook the Lasagna Noodles: Boil the lasagna noodles according to package instructions. Drain and set aside.

3. Prepare the Filling: In a large mixing bowl, combine the ricotta cheese, 1/2 cup of mozzarella cheese, Parmesan cheese, chopped spinach, chopped mushrooms, egg, garlic powder, onion powder, salt, and pepper. Mix well until fully combined.

4. Fill the Noodles: Lay out each lasagna noodle flat on a clean surface. Spoon a generous amount of the filling onto each noodle, spreading it evenly.

5. Roll the Noodles: Starting from one end, gently roll each noodle to create a tight roll. Place them seam-side down in a greased baking dish.

6. Add Sauce: Pour about 1 cup of marinara sauce over the rolled noodles, ensuring all rolls are coated well.

7. Top with Cheese: Sprinkle the remaining mozzarella cheese over the top.

8. Bake: Cover the baking dish with aluminum foil and bake in the preheated oven for 25 minutes. Remove the foil and bake for an additional 10 minutes until the cheese is bubbly and golden.

9. Garnish: Once out of the oven, let the rolls sit for a few minutes. Garnish with fresh basil if desired.

10. Serve: Serve your delicious Mushroom and Spinach Lasagna Rolls with additional marinara sauce on the side.
