Choosing the Perfect Italian Sausage
When it comes to sausages, quality matters. Opt for authentic Italian sausages—mild or spicy, depending on your taste. Local butcher shops often have the best options.
Step-by-Step Recipe Instructions
- Prep the Pasta: Boil the pasta in salted water until al dente. Drain and set aside.
- Cook the Sausage: Heat olive oil in a skillet. Slice the sausages into rounds, cook until browned, and remove.
- Sauté Veggies: In the same skillet, sauté onions, garlic, and bell peppers until softened.
- Combine Ingredients: Mix the sausage, cooked pasta, marinara sauce, Italian seasoning, and half the mozzarella in a large bowl.
- Assemble the Casserole: Pour the mixture into a greased baking dish. Top with the remaining mozzarella and Parmesan.
- Bake: Bake at 375°F (190°C) for 20-25 minutes, or until bubbly and golden.
- Garnish and Serve: Sprinkle with fresh basil and serve hot.
Tips for Making the Best Casserole
- Undercook the pasta slightly—it will cook more in the oven.
- Use freshly shredded cheese for better melting.
- Add a pinch of red pepper flakes for extra heat.

How to Store and Reheat

Recipe Variations to Try

Common Mistakes to Avoid
