Step 1: Cook the Pasta
Bring a large pot of salted water to a boil.
Cook the penne until just al dente according to package directions.
Drain well.
Do not overcook, as the pasta will continue cooking in the oven.
Step 2: Brown the Sausage
Heat a large skillet over medium heat.
Add the sliced sausage.
Cook for 5–7 minutes until lightly browned.
The caramelization adds incredible flavor.
Step 3: Cook the Vegetables (Optional)
If using peppers and onions, add them to the skillet.
Cook until softened.
Stir in garlic during the final minute.
Step 4: Add the Sauce
Pour the marinara sauce into the skillet.
Add Italian seasoning if desired.
Allow everything to simmer for 5 minutes.
This helps all the flavors blend together.
Step 5: Combine Everything
Add the cooked pasta to the skillet.
Mix gently until every piece is coated with sauce.
Stir in half of the mozzarella cheese.
Step 6: Assemble the Casserole
Lightly grease a baking dish.
Spread the pasta mixture evenly.
Top with the remaining mozzarella cheese.
For extra flavor, sprinkle Parmesan over the top.
Step 7: Bake
Preheat the oven to 375°F (190°C).
Bake uncovered for 20–25 minutes.
The cheese should melt completely and become lightly golden.
For a crispier topping, broil for 2–3 minutes at the end.
