There’s something irresistibly comforting about a tray of baked pasta: bubbling sauce, gooey cheese, and tender shells holding a creamy filling. This Classic Stuffed Shells (with Cottage Cheese) recipe hits all those notes with a simple, pantry-friendly ingredient list and a reliably satisfying finish. It’s the kind of dish that doubles as weeknight dinner and weekend company food, and it’s easy to scale up or down depending on how many mouths you need to feed.

Why this version works

Using cottage cheese in the filling yields a lighter, slightly tangy interior that contrasts beautifully with melted mozzarella and a nutty shower of Parmigiano Reggiano. The mix of two sauces—marinara for brightness and alfredo for richness—creates a more complex, restaurant-style flavor without extra fuss. Follow the step-by-step directions below to achieve tender shells, a creamy filling that won’t weep, and evenly baked, golden cheese on top.

Ingredients

12 oz pasta shells (1 box, about 40 shells)
4 cups low-fat cottage cheese
2 cups grated mozzarella cheese, divided
3/4 cup grated Parmigiano Reggiano cheese
2 large eggs
1 teaspoon dried oregano
1 teaspoon dried basil
salt and pepper to taste
48 oz marinara sauce (2 jars of Rao’s recommended)
15 oz alfredo sauce (1 jar)
chopped fresh parsley, optional, for garnish

Equipment and prep notes

Large pot for boiling pasta
Large bowl for mixing the filling
9×13-inch baking dish (or similar)
Slotted spoon or tongs for removing shells
Spoon or piping bag to fill shells

Bring a large pot of salted water to a rolling boil before adding the pasta shells. Read the box for timing but cook to al dente so the shells hold their shape while you fill them and bake them—about 1 to 2 minutes shy of the package recommendation is usually safe.

Step-by-step instructions

Preheat and prepare: Position a rack in the center of your oven and preheat to 375°F (190°C). Lightly grease a 9×13-inch baking dish so the sauce and shells won’t stick.
Cook the pasta shells: Bring a large pot of water to a boil and add a generous pinch of salt. Add the 12 oz pasta shells and cook until al dente—tender but slightly firm in the center. This usually means removing them about 1–2 minutes before the package’s full cooking time. Drain the shells and rinse briefly with cool water to stop cooking and make them easier to handle. Set aside on a tray or in a single layer so they don’t stick together.
Make the filling: In a large mixing bowl, combine 4 cups low-fat cottage cheese, 1 cup of the grated mozzarella (reserve the other cup for topping), 3/4 cup grated Parmigiano Reggiano, 2 large eggs, 1 teaspoon dried oregano, 1 teaspoon dried basil, and salt and pepper to taste. Stir until the mixture is evenly combined and creamy. Taste and adjust salt and pepper if needed—the cheeses provide saltiness, so add gradually.
Mix sauces: In a separate bowl or measuring cup, stir together the 48 oz marinara sauce and the 15 oz alfredo sauce until smooth and evenly blended. This combined sauce will be the base in the baking dish and will also help keep the shells moist during baking.
Prepare the baking dish: Spread about one-third of the combined sauce evenly across the bottom of the greased 9×13-inch baking dish. This layer creates a saucy bed so shells don’t stick and so each bite is coated with sauce.
Fill the shells: Using a spoon or a small cookie scoop, fill each cooled shell with about 1–2 tablespoons of the cottage-cheese mixture—enough to generously fill but not overstuff. Work systematically, placing each filled shell upright in the baking dish, open-side up. Arrange the shells in a single layer; you should have room for about 40 shells if using a full 12 oz box. If you have leftover filling, spread a thin layer over the sauce between shells or reserve for another use.
Top with sauce and cheese: Once all shells are filled and arranged, spoon the remaining combined sauce evenly over the tops of the shells so they are mostly covered. Sprinkle the remaining 1 cup grated mozzarella over the sauced shells, then finish with a light dusting of extra Parmigiano Reggiano if you like a little more savory crust.
Bake: Cover the dish loosely with foil and bake in the preheated 375°F (190°C) oven for 20 minutes. After 20 minutes, remove the foil and continue baking for 10–15 minutes, or until the cheese on top is melted and lightly golden and the sauce is bubbling along the edges. If you prefer a deeper brown on top, broil for 1–2 minutes at the end—watch closely to avoid burning.
Rest and garnish: Remove the baked shells from the oven and let them rest for 5–10 minutes. This short rest allows the filling to set slightly so the shells hold their shape when served. Sprinkle with chopped fresh parsley if desired, and serve warm.

Serving suggestions

This Classic Stuffed Shells (with Cottage Cheese) meal is rich and versatile. Serve with a crisp green salad dressed with lemon and olive oil to cut through the creaminess. Garlic bread or a simple bruschetta are classic companions, and a light side of sautéed greens—spinach, Swiss chard, or kale—adds color and balance. For family-style entertaining, place the baking dish on the table with a large serving spoon so everyone can help themselves.

Make-ahead and storage tips

Assemble ahead: Prepare the shells through step 7, cover with plastic wrap, and refrigerate for up to 24 hours before baking. Add a few extra minutes to the baking time if coming out of the refrigerator cold.
Freeze: To freeze, assemble the shells in an oven-safe dish, cover tightly with foil, and freeze for up to 3 months. Thaw overnight in the refrigerator and bake as directed, adding 10–15 minutes if still cold from the fridge. If baking from frozen, bake covered at 375°F (190°C) for about 45–60 minutes, uncovered for the last 10–15 minutes to brown the top.
Reheat: Leftovers keep well in the refrigerator for 3–4 days. Reheat single portions in a microwave or reheat the whole dish covered at 350°F (175°C) until warmed through, about 20–30 minutes depending on portion size.

Tips for success

Don’t overcook shells: Slightly undercooked shells are easier to fill and won’t turn mushy once baked.
Keep the filling thick: If your cottage cheese filling feels too loose, briefly drain excess liquid in a fine-mesh strainer or add a tablespoon of breadcrumbs to bind slightly. The eggs and cheese will help the filling set during baking.
Even sauce coverage: Make sure each shell is at least partially covered by sauce during baking to prevent the tops from drying out.
Flavor boost: For a fresh lift, stir a tablespoon or two of chopped fresh basil into the filling when available.

Variations

This Classic Stuffed Shells (with Cottage Cheese) recipe adapts easily. For a vegetable-forward version, fold in sautéed spinach, mushrooms, or roasted red peppers into the filling. For more protein, add a cup of cooked, shredded poultry or plant-based crumbles stirred into the filling—be sure any additions complement the cheese ratios so the texture remains creamy.

Nutrition overview

Because this recipe uses a combination of cottage cheese, mozzarella, and Parmigiano Reggiano, it delivers a good amount of protein and calcium. Choosing low-fat cottage cheese reduces some saturated fat while still keeping the filling creamy. Balancing the meal with a green salad or steamed vegetables will round out the plate and add fiber and vitamins.

Final notes

This Classic Stuffed Shells (with Cottage Cheese) recipe is straightforward, comforting, and forgiving—perfect for cooks who want a homey baked pasta without complicated technique. The dual-sauce approach—marinara for acidity and alfredo for richness—creates depth, and the cottage cheese filling keeps things lighter and pleasantly textured. Make it for a crowd, freeze portions for busy nights, or enjoy it as a weekend indulgence. Either way, it’s bound to become a repeat in your rotation.

If you try this recipe, take note of what you loved and what you might tweak—more herbs, a dash of crushed red pepper, or a swirl of pesto on top are all easy adjustments. Enjoy the process: this is comfort food you can share, savor, and customize.

Method

Preheat the oven to 375°F (190°C).
Bring a large pot of salted water to a boil and cook the pasta shells for about 8 minutes until al dente; drain, rinse with cold water, and let them drain thoroughly.
Pour the marinara sauce into the bottoms of two 9×13-inch baking dishes, dividing it evenly between the pans (one jar per pan).
In a large bowl, combine the cottage cheese, 1 cup grated mozzarella, Parmigiano Reggiano, eggs, dried oregano, dried basil, and salt and pepper to taste; stir until well mixed.
Fill a piping bag or a large freezer bag fitted with a 1-inch hole (or use a spoon) and pipe or spoon the cheese mixture into each shell until filled.
Arrange the filled shells in the prepared baking dishes, placing about 20 shells in each pan.
Spoon the Alfredo sauce over the filled shells, then sprinkle the remaining 1 cup of grated mozzarella evenly over both pans (about 1/2 cup per pan).
Cover each pan with aluminum foil (spray the underside with nonstick spray if desired) and bake for 30 minutes; remove the foil and bake uncovered for an additional 15 minutes to brown the tops.
Let the dishes rest for 5–10 minutes after baking, sprinkle with chopped parsley if using, and serve hot.
