Spicy Sausage and Spinach Lasagna

1.Preheat your oven to 375°F (190°C).

2.In a large skillet, heat a drizzle of olive oil over medium heat. Add the diced onion and sauté until translucent, about 5 minutes. Stir in the minced garlic and red pepper flakes, cooking for an additional minute until fragrant.

3.Add the spicy Italian sausage to the skillet, breaking it apart with a spoon. Cook until browned and cooked through, about 7-10 minutes. Drain excess fat if necessary.

4.Stir in the crushed tomatoes and chopped spinach. Season with salt, pepper, oregano, and basil. Let the mixture simmer for about 10 minutes, allowing the flavors to meld together.

5.In a mixing bowl, combine the ricotta cheese, egg, and a pinch of salt and pepper. Mix until smooth and well combined.

6.In a 9x13 inch baking dish, spread a thin layer of the sausage and spinach mixture on the bottom. Place 4 lasagna noodles over the sauce, then spread half of the ricotta mixture over the noodles. Sprinkle with a third of the mozzarella cheese and a quarter of the Parmesan cheese.

7.Repeat the layers: add another layer of the sausage and spinach mixture, followed by 4 more noodles, the remaining ricotta mixture, and another third of the mozzarella cheese. Top with the final 4 noodles, the remaining sausage and spinach mixture, and the rest of the mozzarella and Parmesan cheese.

8.Cover the baking dish with aluminum foil and bake in the preheated oven for 25 minutes. Remove the foil and bake for an additional 15-20 minutes, or until the cheese is bubbly and golden brown.

9.Let the lasagna cool for about 10 minutes before slicing. Serve warm and enjoy your spicy sausage and spinach lasagna!
