Preparing the Noodles:

• Cook the noodles: Bring a large pot of salted water to a boil. Add the lasagna noodles and cook according to the package instructions until al dente. Drain the noodles and rinse under cold water to stop the cooking process. Lay the noodles flat on a clean kitchen towel or parchment paper to prevent them from sticking together.

Making the Filling:

• Prepare the filling: In a medium bowl, combine ricotta cheese, shredded mozzarella, grated Parmesan, egg, chopped spinach, garlic powder, oregano, salt, and pepper. Stir everything together until well combined.

Assembling the Roll Ups:

• Preheat the oven: Preheat your oven to 375°F (190°C). Spread ½ cup of marinara sauce evenly in the bottom of a 9×13-inch baking dish.

• Stuff the noodles: Take each lasagna noodle and spread a generous amount of ricotta filling along the entire length of the noodle. Roll the noodle up tightly and place it seam-side down in the prepared baking dish.

• Top with sauce: Once all the noodles are rolled up and placed in the dish, pour the remaining marinara sauce over the top. Sprinkle with additional shredded mozzarella cheese.

Baking:

• Bake the roll-ups: Cover the baking dish with aluminum foil and bake in the preheated oven for 25 minutes. After 25 minutes, remove the foil and bake for an additional 10-15 minutes, or until the cheese is bubbly and golden.

Serving:

• Garnish and serve: Remove from the oven and let the roll-ups cool for a few minutes. Garnish with fresh basil or parsley before serving.
