Recipe Information
Ingredients
- 12 oz penne pasta
- 1 lb Italian sausage (mild or spicy)
- 4 cups spinach (fresh, roughly chopped)
- 1 medium yellow onion (diced)
- 3 cloves garlic (minced)
- 28 oz crushed tomatoes (canned)
- 2 tbsp tomato paste
- 1 tsp dried Italian seasoning
- 0.5 tsp red pepper flakes (optional)
- 0.5 tsp salt
- 0.5 tsp black pepper
- 1 cup ricotta cheese
- 2 cups shredded mozzarella cheese
- 0.5 cup grated Parmesan cheese
- 2 tbsp olive oil
Instructions
Preheat your oven to 375°F (190°C). Grease a 9x13-inch casserole dish with olive oil or non-stick spray and set aside.
In a large pot, bring salted water to a boil and cook the penne pasta according to package instructions until al dente. Drain and set aside.
In a large skillet, heat olive oil over medium heat. Add the diced onion and cook until softened, about 3-4 minutes. Add the minced garlic and cook for an additional 1 minute, stirring frequently.
Add the Italian sausage to the skillet, breaking it into small pieces with a wooden spoon. Cook until browned and fully cooked through, about 7-8 minutes. Drain any excess fat if needed.
Stir in the crushed tomatoes, tomato paste, dried Italian seasoning, red pepper flakes (if using), salt, and black pepper. Simmer the sauce for 10 minutes, stirring occasionally.
Add the chopped spinach to the skillet and stir until wilted, about 1-2 minutes. Remove the skillet from heat.
In a large mixing bowl, combine the cooked penne pasta with the sausage and spinach sauce, stirring until well coated.
Transfer half of the pasta mixture to the prepared casserole dish. Spread the ricotta cheese evenly over the top, then layer with 1 cup of shredded mozzarella cheese.
Add the remaining pasta mixture on top, then sprinkle with the remaining 1 cup of mozzarella cheese and grated Parmesan cheese.
Cover the casserole dish with aluminum foil and bake in the preheated oven for 20 minutes. Remove the foil and bake for an additional 10-15 minutes, or until the cheese is melted and bubbly.
Remove the casserole from the oven and let it rest for 5 minutes before serving. Enjoy your Sausage and Spinach Penne Casserole!
