Ingredients:
- 1 lb Italian sausage, ground
- 9 lasagna noodles (flat sheets)
- 15 oz whole milk ricotta cheese
- 10 oz fresh spinach, coarsely chopped
- 1 large egg
- 1/4 cup grated Parmesan cheese
- 24 oz marinara sauce (jarred or homemade)
- 1 1/2 cups shredded whole milk mozzarella cheese
- 1 teaspoon dried oregano
- 1 teaspoon garlic powder
- 1 teaspoon salt
- 1/2 teaspoon black pepper
Instructions:
- Cook the lasagna noodles according to package directions until slightly underdone (al dente). Drain immediately and lay flat on parchment paper or clean towels to prevent sticking.
- In a large skillet, brown the Italian sausage over medium-high heat, breaking it up as it cooks. Drain thoroughly to remove excess grease.
- In a medium bowl, combine the ricotta cheese, wilted spinach, egg, Parmesan cheese, dried oregano, garlic powder, salt, and pepper. Stir until the filling is uniform and well-mixed. The egg acts as a crucial binder.
- Preheat the oven to 375°F (190°C). Pour half of the marinara sauce into the bottom of a 9x13 inch baking dish.
- To assemble the rolls, spread a thin, even layer of the ricotta mixture over each cooked lasagna noodle, leaving a small border around the edges. Spoon a line of the browned sausage over the filling mixture.
- Starting from one end, tightly roll up each noodle and place it seam-side down in the prepared baking dish. Ensure rolls are snug but not squeezed.
- Top the rolls with the remaining marinara sauce, ensuring the pasta edges are covered to prevent drying out. Sprinkle evenly with the shredded mozzarella cheese.
- Bake for 20 minutes, or until the cheese is melted, bubbly, and lightly golden brown. Let rest for 5 minutes before serving to allow the rolls to set.
