Ingredients You’ll Need
- 8 oz medium pasta shells: These create a lovely bite-sized shape, perfect for holding sauce. If you don’t have shells, feel free to use penne or rigatoni instead.
- 2 teaspoons olive oil: Adds richness to the sauce. You can substitute with any cooking oil you have on hand.
- 3 garlic cloves, minced: This gives a pungent, aromatic kick to the dish. Freshly minced is best!
- ½ cup shallots, minced (or onions): Shallots bring a mildly sweet flavor. Onions are a good substitute if needed.
- 12 oz Italian sausage: Adds depth and heartiness. You can use chicken sausage or even a vegetarian version for a lighter option.
- 28 oz can crushed tomatoes: The base of the sauce. Look for high-quality, unsalted varieties for the best flavor.
- 1 tablespoon tomato paste: Concentrated tomato flavor that enhances the sauce.
- 1 ½ tablespoons granulated sugar: Balances out the acidity of the tomatoes. You can skip this if you prefer.
- ½ teaspoon kosher salt: Essential for enhancing all the flavors. Adjust more to taste.
- ½ teaspoon freshly ground black pepper: Adds a touch of warmth and spice.
- Pinch red pepper flakes (optional): For those who like a bit of heat, this is a great addition.
- ¾ cup low fat (2%) cottage cheese, small curds: Gives a creamy texture while keeping calories in check. Ricotta can be used as an alternative.
- 6 oz mozzarella cheese, cut into ½-inch cubes: Melts beautifully, offering a gooey texture. Feel free to mix in provolone or fontina.
- 1 cup shredded mozzarella cheese: Adds an extra layer of cheesy goodness on top.
- Chopped Italian parsley for garnish: This not only adds color but also a fresh flavor. Fresh basil is an excellent choice too.
How to Make Baked Penne | Cheesy Oven-Baked Pasta Casserole
Cook pasta: First, bring a large pot of salted water to a boil. Add 8 oz of medium pasta shells and cook according to package directions until al dente. This usually takes about 8-10 minutes. Once done, drain the pasta and let it cool for a minute.
Make sauce: In a medium pot, heat 2 teaspoons of olive oil over medium heat. Add 3 minced garlic cloves and ½ cup minced shallots. Cook for about 2-3 minutes until softened and fragrant, stirring often. Next, add in 12 oz of Italian sausage, breaking it into small pieces, and cook until browned, which should take around 5-7 minutes. Be sure to drain any excess fat afterwards for a cleaner flavor.
Simmer: It’s time to transform this into a sauce. Add in a 28 oz can of crushed tomatoes, 1 tablespoon of tomato paste, 1 ½ tablespoons granulated sugar, ½ teaspoon kosher salt, and ½ teaspoon freshly ground black pepper. If you enjoy a little spice, throw in a pinch of red pepper flakes too. Bring the mixture to a boil, then reduce to a simmer and let it cook for 10-15 minutes, allowing all those flavors to meld beautifully. Afterward, taste and adjust seasoning if needed. Let it cool for about 15 minutes.
Assemble: Preheat your oven to 350°F (175°C). In a large mixing bowl, combine the cooled pasta, the cooled sauce, ¾ cup of low-fat cottage cheese, and 6 oz of cubed mozzarella cheese. Toss everything together until well mixed. Transfer the mixture to a 9×13-inch baking dish, spreading it evenly, and then top it with 1 cup of shredded mozzarella cheese.
Bake: Now it’s time for the oven magic! Bake for about 20 minutes, or until the cheese is bubbly and melted. If you want that gorgeous golden brown top, set the oven to broil for 30-45 seconds, but keep a close eye on it to prevent burning. Once done, let the casserole stand for 5-8 minutes before serving. Garnish with fresh parsley for a pop of color!

Storing & Reheating
You can store any leftovers at room temperature for a couple of hours, but it’s best to refrigerate them in an airtight container for up to 5 days. If you want to make it ahead of time, consider freezing portions in freezer-safe containers for up to 3 months. Reheat in the oven at 350°F for about 15-20 minutes, or until heated through, but be aware that the texture may change slightly. A splash of water can help refresh it and prevent drying out.
Chef’s Helpful Tips
- Be careful not to overcook the pasta; you want it al dente since it will continue to cook while baking.
- If using frozen sausage, make sure to fully thaw before cooking.
- Don’t be shy with seasonings; always taste your sauce as it simmers.
- For an extra cheesy experience, add more mozzarella or other cheeses of your choice.
- This dish can be prepped a day ahead; just assemble and refrigerate before baking.
- If you have picky eaters, consider swapping out the sausage with ground turkey or beef for different flavors.
