Ingredients You’ll Need
- 8 oz medium pasta shells: A pasta that holds sauce well, these shells offer the perfect bite. You can substitute with penne or rigatoni if preferred.
- 2 teaspoons olive oil: This oil adds a subtle fruitiness to the dish. Can be replaced with any neutral cooking oil like canola or vegetable oil.
- 3 garlic cloves, minced: Fresh garlic enhances the flavor profile with its aromatic qualities. Feel free to use jarred minced garlic in a pinch, but fresh is best!
- ½ cup shallots, minced: Shallots provide a milder onion flavor but can be swapped with onions or yellow onions if needed.
- 12 oz Italian sausage: Sausage gives the dish that rich meaty flavor; opt for hot or mild, based on your spice preference. Turkey sausage offers a lighter alternative.
- 28 oz can crushed tomatoes: The base of the sauce; crushed tomatoes create a nice consistency. Whole or diced tomatoes can also work if pureed.
- 1 tablespoon tomato paste: For an extra punch of tomato flavor, essential for depth. If you don’t have any, you can double the crushed tomatoes.
- 1 ½ tablespoons granulated sugar: A touch of sweetness balances the acidity of the tomatoes. Brown sugar can be an interesting twist here too!
- ½ teaspoon kosher salt: Always season to taste; adjust based on your preference and diet.
- ½ teaspoon freshly ground black pepper: Adds a subtle warmth; feel free to use white pepper for a different flavor profile.
- Pinch red pepper flakes, optional: Introduces a hint of heat but can be omitted if you want a milder dish.
- ¾ cup low-fat (2%) cottage cheese, small curds: This adds creaminess without too much fat. Ricotta cheese makes a lovely substitution.
- 6 oz mozzarella cheese, cut into ½-inch cubes: Provides melty goodness throughout the pasta. You can use low-fat mozzarella or a dairy-free option if desired.
- 1 cup shredded mozzarella cheese: This is for the topping, creating a beautiful, bubbly crust. A mix of mozzarella and provolone takes it up a notch!
- Chopped Italian parsley, for garnish: Fresh herbs elevate any dish with a burst of color and flavor.
How to Make Baked Penne | Cheesy Oven-Baked Pasta Casserole
Cook pasta: Prepare the 8 oz medium pasta shells according to package directions until al dente. This ensures the pasta holds its shape during baking. Once cooked, drain and set aside to cool slightly.
Make sauce: Heat 2 teaspoons of olive oil in a medium pot over medium heat. Add the minced 3 garlic cloves and ½ cup minced shallots, cooking for about 2-3 minutes until softened and fragrant. Next, add in the 12 oz Italian sausage, breaking it apart as it browns. Cook until fully browned, then drain any excess fat.
Simmer: Pour in the 28 oz can of crushed tomatoes, adding 1 tablespoon of tomato paste, 1 ½ tablespoons of granulated sugar, ½ teaspoon of kosher salt, ½ teaspoon of freshly ground black pepper, and a pinch of red pepper flakes if using. Stir well, bringing to a boil, then reduce to a simmer for 10-15 minutes until flavorful. Don’t forget to taste and adjust seasoning as needed. Allow the mixture to cool for 15 minutes.
Assemble: Preheat your oven to 350°F. In a large mixing bowl, combine the cooled pasta, cooled sauce, ¾ cup cottage cheese, and 6 oz mozzarella cubes. Toss everything together until well mixed, then transfer the mixture into a 9×13-inch baking dish. Top off with 1 cup of shredded mozzarella cheese for that cheesy, bubbly finish.
Bake: Pop it into the preheated oven and bake for 20 minutes until the cheese is melted and bubbly. For that golden touch, you can broil for an additional 30-45 seconds. Just keep an eye on it to avoid burning. Let it stand for 5-8 minutes before serving. Make it pretty by garnishing with some chopped Italian parsley!

Storing & Reheating
To store leftover Baked Penne, simply keep it in an airtight container in the refrigerator, where it will stay fresh for up to 3-4 days. If you want to freeze it, tightly wrap the casserole dish in plastic wrap and then foil for up to 3 months. Reheat in the oven at 350°F for about 20-25 minutes or until heated through. The texture may change slightly, so refreshing it with a touch of sauce can restore some moisture!
Chef’s Helpful Tips
- Avoid overcooking the pasta; al dente is key since it will continue cooking in the oven.
- Let the sauce cool a bit before combining it with the pasta to prevent curdling of the cheese.
- Use fresh ingredients whenever possible for the best flavor profile—fresh herbs and sausage make a world of difference.
- If you have leftovers, consider adding a little bit of cream before reheating for a creamier texture.
- For an extra herbaceous touch, add in some Italian herbs like basil or oregano to the sauce.
