- 1 tablespoon tomato paste: Intensifies the tomato flavor; don’t skip this!
- 1 ½ tablespoons granulated sugar: Balances the acidity of the tomatoes.

- Pinch red pepper flakes (optional): If you enjoy a little heat, this is a great addition.
- ¾ cup low-fat (2%) cottage cheese, small curds: Adds creaminess and richness; the low-fat variety keeps it lighter.
- 6 oz mozzarella cheese, cut into ½-inch cubes: Melts beautifully for a gooey texture.
- 1 cup shredded mozzarella cheese: For the irresistible cheesy layer on top.
- Chopped Italian parsley, for garnish: Brings a fresh touch and color to the dish.
How to Make Baked Penne | Cheesy Oven-Baked Pasta Casserole
Cook pasta: Prepare the medium pasta shells according to package directions until they are al dente. Once cooked, drain them and set aside to cool. This step is vital, as overcooked pasta may become mushy during baking.
Make sauce: In a medium pot, heat 2 teaspoons of olive oil over medium heat. Add in the minced garlic and shallots, cooking them for about 2-3 minutes until softened and fragrant, stirring frequently. Toss in the 12 oz of Italian sausage, breaking it into small pieces, and cook until it’s browned, about 5-7 minutes. Be sure to drain any excess fat to keep the dish from becoming greasy.
Simmer: Stir in the 28 oz can of crushed tomatoes, 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). Bring the mixture to a boil, reduce to a simmer, and let it bubble away for 10-15 minutes. This allows the flavors to meld beautifully. Don’t forget to taste and adjust the seasoning as you see fit. Allow the sauce to cool for about 15 minutes before the next step.
Assemble: Preheat your oven to 350°F. In a large bowl, combine the cooled pasta, cooled sauce, ¾ cup of low-fat cottage cheese, and the 6 oz of cubed mozzarella cheese. Toss everything together until combined. Transfer this wonderful mixture to a 9×13-inch baking dish and spread evenly. Finally, top it off with 1 cup of shredded mozzarella cheese, creating the crowning glory!
Bake: Place the baking dish in the preheated oven and bake for approximately 20 minutes, or until the cheese has melted and the edges begin to bubble. For a beautiful golden top, broil for 30-45 seconds; just keep a close eye on it so it doesn’t burn. Once it’s done, allow it to stand for 5-8 minutes before serving. Garnish with chopped Italian parsley for that fresh finish.

Storing & Reheating
This dish can be stored at room temperature for about 2 hours before it should be refrigerated. To store in the refrigerator, use an airtight container for up to 3 days. If you’re looking to freeze, wrap individual portions tightly in plastic wrap or foil, then store in a freezer-safe bag for up to 3 months. For reheating, pop it in the oven at 350°F for 20-25 minutes or microwave in 1-minute intervals until heated through. Keep in mind that the texture may change slightly as it ages, so adding a splash of water or a drizzle of olive oil before reheating can help refresh it.
Chef’s Helpful Tips
- Make sure to always taste your sauce before baking to adjust the seasoning to your liking.
- If using dry pasta, remember that it will absorb some liquid during baking, so slightly undercook it to maintain the desired texture.
- For an extra layer of flavor, you can sauté some spinach or mushrooms along with the sausage.
- Make it ahead of time! You can assemble the casserole a day in advance and bake it the next day—just add an extra 5-10 minutes to the baking time if you bake it from the fridge.
- If you want an even cheesier version, feel free to layer different types of cheese in between.

Recipe FAQs
Can I use other types of pasta for this casserole?
Absolutely! While medium pasta shells work perfectly, you can swap them for penne, rotini, or even fusilli. Just make sure to adjust cooking times according to the package instructions to ensure they’re al dente before baking.
Can I make this dish vegetarian?
Yes! Simply replace the Italian sausage with a plant-based sausage or load it up with your favorite vegetables like zucchini, mushrooms, or bell peppers. You can even add some spinach for extra nutrition.
How do I know when my casserole is done?
You’ll know it’s ready when the cheese is bubbly and golden brown on top. A good rule of thumb is to check around the 20-minute mark; if the edges are bubbling and the center feels hot, it’s time to take it out!
Can I prepare this casserole in advance?
Definitely! You can assemble the casserole ahead of time and keep it covered in the fridge for up to 24 hours before baking. Just make sure to add a few more minutes to the baking time since it will be cold when you put it in the oven.
