Step-by-step instructions
Now that you have everything prepped, let’s get cooking! Follow these simple directions:
- Preheat your oven to 375°F (190°C).
- Cook the penne pasta according to the package instructions until al dente; drain and set aside.
- Heat olive oil in a large skillet over medium heat. Add the chopped onion, minced garlic, red bell pepper, and zucchini. Sauté until the vegetables are softened, about 5-7 minutes.
- Add the Italian sausage to the skillet, breaking it apart with a spoon, and cook until well browned and fully cooked through.
- Stir in the crushed tomatoes, oregano, basil, red pepper flakes, salt, and pepper. Allow it to simmer for about 5 minutes.
- Pour in the heavy cream and mix thoroughly.
- Combine your cooked pasta with the sausage mixture, then stir in half of the mozzarella cheese.
- Transfer this mixture into a baking dish and top with the remaining mozzarella and Parmesan cheese.
- Bake in your preheated oven for about 20-25 minutes, or until the cheese is bubbly and golden.
- Garnish with fresh basil leaves before serving.

How to store
Got some leftovers? No problem! Store any uneaten portions in an airtight container in the refrigerator for up to 3-4 days. For longer storage, you can freeze the baked pasta for up to 2 months.

Helpful cooking tips
- Pasta Cooking: Make sure not to overcook the pasta in the first step—it should be al dente since it’ll continue cooking in the oven.
- Sausage Flavor: For a spicier kick, use spicy Italian sausage instead of mild. It adds an extra layer of depth to the dish.
- Extra Veggies: Feel free to add more vegetables like spinach or mushrooms for added nutrition and flavor.
