Ingredients You’ll Need
- 8 oz medium pasta shells: A great choice for holding onto the creamy sauce and flavors. You can substitute with other shapes like penne or rigatoni if desired.
- 2 teaspoon olive oil: For sautéing the garlic and shallots. Feel free to use any cooking oil you prefer.
- 3 garlic cloves, minced: Adds a fragrant punch. Use fresh garlic for the most flavor; jarred may not yield the same aromatic experience.
- ½ cup shallots, minced: These bring a sweet and subtle flavor compared to standard onions. Onions can be substituted if needed.
- 12 oz Italian sausage, removed from casing: Gives a delicious, hearty flavor. You can use chicken or turkey sausage for a lighter version.
- 28 oz can crushed tomatoes: Provides the base for our savory sauce. Opt for high-quality tomatoes for the best taste.
- 1 tablespoon tomato paste: Intensifies the tomato flavor and adds thickness to the sauce. Always check for low-sodium options if you’re watching your salt intake.
- 1 ½ tablespoon granulated sugar: Balances the acidity of the tomatoes. Make sure to taste and adjust if needed.
- ½ teaspoon kosher salt: Essential for seasoning the dish. Adjust according to your personal taste preference.
- ½ teaspoon freshly ground black pepper: Provides a mild heat; freshly ground will have more flavor.
- Pinch red pepper flakes, optional: For a touch of warmth. Feel free to skip if you prefer a milder dish.
- ¾ cup low-fat (2%) cottage cheese, small curds: Adds creaminess with less fat than traditional ricotta.
- 6 oz mozzarella cheese, cut into ½-inch cubes: Melts beautifully, creating gooey pockets of cheese throughout the dish.
- 1 cup shredded mozzarella cheese: Topping for baking that provides a glorious cheesy crust.
- Chopped Italian parsley, for garnish: Adds a pop of color and a fresh flavor to finish off the dish.
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. Drain and let cool a bit while you make the sauce. This allows the pasta to hold its shape during baking.
Make sauce: Heat 2 teaspoons olive oil in a medium pot over medium heat. Add 3 minced garlic cloves and ½ cup minced shallots; cook for 2-3 minutes until softened, stirring often. Add 12 oz Italian sausage and cook until browned, breaking it into small pieces as it cooks. Don’t forget to drain any excess fat to keep the sauce from getting too greasy!
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 for a little kick if desired. Bring the mixture to a boil, then reduce to a simmer and let cook for about 10-15 minutes. Check the seasoning and let cool for about 15 minutes.
Assemble: Preheat your oven to 350°F. In a large bowl, combine the cooled pasta, cooled sauce, ¾ cup low-fat cottage cheese, and 6 oz mozzarella cubes. Toss everything together until well-coated. Transfer the mixture to a 9×13-inch baking dish, ensuring an even spread. Top generously with 1 cup shredded mozzarella cheese.
Bake: Slide the baking dish into the oven and bake for about 20 minutes, or until the cheese is melted and bubbly. For that extra touch, broil for 30-45 seconds to get a bubbly, golden top. Once done, let it sit for 5-8 minutes before serving, which helps it set. Garnish with chopped parsley for that fresh finish.

Storing & Reheating
You can store leftovers of this wonderful pasta casserole at room temperature for up to 2 hours. If you have any remaining, transfer them to an airtight container in the fridge where it will last for about 3-4 days. For long-term storage, freeze it wrapped tightly for up to 3 months. To reheat, simply place it in the oven at 350°F for about 20-25 minutes or until warmed throughout. You may find the texture slightly changes, but adding a splash of marinara can refresh those flavors!
Chef’s Helpful Tips
- Avoid overcooking the pasta during the initial boiling; it should be slightly firm since it will continue to cook in the oven.
- If you want a creamier texture, consider adding a bit more cottage cheese, or even a splash of cream.
- Make sure the ingredients are at room temperature before assembly so that everything mixes evenly.
- To enhance the flavor, sprinkle some dried Italian herbs like oregano or basil over the top before baking.
- This dish is perfect for meal prepping as it keeps well and can be reheated easily.
