Ingredients You’ll Need
- 8 oz medium pasta shells: These pasta shells hold onto the delicious sauce and cheese, ensuring every bite is full of flavor.
- 2 teaspoons olive oil: A simple fat that’s perfect for sautéing, but feel free to use your preferred cooking oil.
- 3 garlic cloves, minced: Fresh garlic adds a tremendous depth of flavor to the dish; powdered garlic can work in a pinch.
- ½ cup shallots, minced: Shallots bring a subtle sweetness. If you can’t find them, onions are a fine substitute.
- 12 oz Italian sausage, removed from casing: This is the heart of the dish. Choose hot or mild depending on your heat preference.
- 28 oz can crushed tomatoes: These create the rich sauce base. Fresh tomatoes can be used, but crushed provides convenience.
- 1 tablespoon tomato paste: Adds complexity and richness to the sauce, ensuring it isn’t too watery.
- 1 ½ tablespoons granulated sugar: Balances the acidity of the tomatoes; feel free to adjust based on taste.
- ½ teaspoon kosher salt: Essential for enhancing flavors; adjust based on your specific dietary needs.
- ½ teaspoon freshly ground black pepper: Freshly ground offers a more robust flavor than pre-ground varieties.
- Pinch red pepper flakes (optional): A little heat can elevate the dish, but skip it if you prefer mild flavors.
- ¾ cup low-fat (2%) cottage cheese, small curds: Creamy cottage cheese adds richness while keeping it lighter. Ricotta can be substituted if preferred.
- 6 oz mozzarella cheese, cut into ½-inch cubes: Melts beautifully and adds texture; any mozzarella will do.
- 1 cup shredded mozzarella cheese: This helps create a delicious, gooey top layer.
- Chopped Italian parsley: A fresh garnish that brightens up the dish and adds a pop of color.
How to Make Baked Penne | Cheesy Oven-Baked Pasta Casserole
Cook pasta: Prepare 8 oz medium pasta shells according to package directions until al dente. Once cooked, drain and allow them to cool slightly. This prevents them from overcooking in the oven.
Make sauce: In a medium pot, heat 2 teaspoons olive oil over medium heat. Add 3 minced garlic cloves and ½ cup finely minced shallots, and sauté for about 2-3 minutes until fragrant and softened. Next, add 12 oz Italian sausage, breaking it down into small pieces with a spatula. Cook until browned and crumbly, then drain excess fat for a healthier option.
Simmer: Stir in 28 oz crushed tomatoes, 1 tablespoon tomato paste, 1 ½ tablespoons granulated sugar, ½ teaspoon kosher salt, ½ teaspoon freshly ground black pepper, and a pinch of red pepper flakes (if using). Bring the mixture to a boil, then reduce the heat to simmer and allow to cook for 10-15 minutes. This simmering melds the flavors beautifully. After simmering, let the sauce cool for about 15 minutes before mixing it with the pasta.
Assemble: Preheat your oven to 350°F. In a large mixing bowl, combine the cooled pasta shells, cooled sauce, ¾ cup low-fat cottage cheese, and 6 oz mozzarella cubes. Toss everything well to ensure it’s evenly mixed. Transfer the mixture into a 9×13-inch baking dish, and top it off with 1 cup shredded mozzarella cheese for that luscious gooey topping.
Bake: Place the baking dish in the oven and bake for 20 minutes until the cheese is melted and bubbly. For an extra touch, broil for 30-45 seconds to achieve that golden-brown, slightly crisp top. Finally, let the casserole stand for about 5-8 minutes before serving to help the flavors settle. Garnish with chopped Italian parsley for that fresh finish.

Storing & Reheating
To store, cover any leftover Cheesy Baked Pasta and keep it at room temperature for up to 2 hours. For longer storage, transfer leftovers to an airtight container in the refrigerator, where they will last for about 3-4 days. If you want to freeze it, place the casserole in a freezer-safe dish and cover securely to prevent freezer burn, storing it for a maximum of 3 months. When ready to enjoy again, reheat in the oven at 350°F for about 20 minutes, or until piping hot throughout. You may notice a slight change in texture, but a splash of tomato sauce can help revive its moisture.
Chef’s Helpful Tips
- Avoid overcooked pasta: Remember to cook the pasta al dente since it continues to cook in the oven.
- Customize your protein: Swap the Italian sausage for turkey sausage or sautéed vegetables for a vegetarian option.
- Cheese varieties: Feel free to mix and match different cheeses like provolone or cheddar for added flavor.
- Flavor boost: Add fresh herbs, like basil or oregano, into the sauce for an aromatic touch.
- Make-ahead: Assemble the casserole a day ahead; just refrigerate before baking. It will save time on busy nights!
