- 3 garlic cloves, minced: Fresh garlic adds robust flavor—use minced from a jar in a pinch.
- ½ cup shallots, minced: Shallots bring a mild sweetness; you can also use a yellow onion if desired.
- 12 oz Italian sausage, removed from casing: Choose sweet or spicy Italian sausage for depth; turkey sausage is a lighter alternative.
- 28 oz can crushed tomatoes: Look for high-quality crushed tomatoes or even make your own from fresh, cooked tomatoes.
- 1 tablespoon tomato paste: Concentrated flavor that enhances sauce richness—store any leftovers in the freezer.
- 1 ½ tablespoons granulated sugar: Counteracts acidity from the tomatoes for a balanced flavor.
- ½ teaspoon kosher salt: Adjust to taste if you prefer—it’s essential for flavor enhancement.

- Pinch red pepper flakes (optional): For a bit of heat, feel free to adjust the amount to your heat preference.
- ¾ cup low-fat cottage cheese (small curds): Adds creaminess and protein; ricotta is a good substitute for a richer texture.
- 6 oz mozzarella cheese, cut into ½-inch cubes: Fresh mozzarella melts beautifully; be sure to pat it dry to prevent excess moisture.
- 1 cup shredded mozzarella cheese: Provides that iconic stretchy cheese topping that holds the casserole together.
- Chopped Italian parsley for garnish: Brightens the dish; it’s optional but adds a lovely finishing touch.
How to Make Baked Penne | Cheesy Oven-Baked Pasta Casserole
Cook pasta: Prepare the pasta shells according to package directions until al dente—this typically takes about 8-10 minutes. Drain them and set aside to cool while you prepare the sauce.
Make sauce: In a medium pot over medium heat, add 2 teaspoons of olive oil. Once warm, sauté 3 minced garlic cloves and ½ cup minced shallots for 2-3 minutes until they soften and become fragrant. Add in the 12 oz Italian sausage, breaking it into small pieces as it browns—cook until no longer pink. Once browned, drain any excess fat.
Simmer: Stir in your 28 oz can of crushed tomatoes, 1 tablespoon tomato paste, 1 ½ tablespoons granulated sugar, ½ teaspoon kosher salt, ½ teaspoon black pepper, and a pinch of red pepper flakes if you like some heat. Bring everything to a gentle boil, then reduce heat to low and let it simmer for about 10-15 minutes, allowing the flavors to meld together. Taste and adjust seasonings if necessary, then let the sauce cool for 15 minutes.
Assemble: Preheat your oven to 350°F. In a large bowl, combine the cooled pasta shells, the cool tomato sauce, ¾ cup of cottage cheese, and the mozzarella cheese cubes. Toss everything together until well mixed and transfer the mixture into a greased 9×13-inch baking dish. Finally, sprinkle the top with 1 cup of shredded mozzarella cheese for that glorious melty topping.
Bake: Place the baking dish in the preheated oven and bake for about 20 minutes or until the cheese is melted and bubbly. For an extra touch, broil the casserole for 30-45 seconds until the top is golden—just keep an eye on it! Once done, allow it to stand for 5-8 minutes before serving. Garnish with freshly chopped parsley for an inviting finish.

Storing & Reheating
Store any leftovers at room temperature for a couple of hours, or refrigerate in an airtight container for up to 3-4 days. If you plan to keep it longer, freeze it for up to 3 months. When ready to enjoy again, simply reheat in the oven at 350°F for about 15-20 minutes or until warmed through. Note that the texture of the pasta may change slightly after freezing, so adding a splash of marinara or a drizzle of olive oil before reheating can help refresh the dish without losing its charm.
Chef’s Helpful Tips
- Avoid overcooking the pasta; it should be just under al dente since it will bake further in the oven.
- If the sauce seems too thick after simmering, add a splash of water or broth to adjust the consistency.
- For a creamier bake, mix an extra layer of cottage cheese or ricotta on top before adding mozzarella.
- Use kitchen shears to chop the parsley directly into the dish for minimal cleanup!
- Consider preparing the casserole a day ahead; it matures and tastes even better the next day.
There’s something undeniably heartwarming about a bubbling dish of pasta that calls to friends and family alike.
