Ingredients

• 12 ounces jumbo pasta shells (about 20 shells)
• 2 cups (16 ounces) full-fat cottage cheese
• 1 cup (4 ounces) shredded low-moisture mozzarella cheese
• 1/2 cup grated Parmesan cheese
• 2 tablespoons Calabrian chili paste (adjust to taste)
• 1 large egg, lightly beaten
• 1/2 teaspoon garlic powder
• 1/2 teaspoon onion powder
• 1/4 teaspoon salt
• 1/4 teaspoon black pepper
• 1 (24-ounce) jar or can of crushed tomatoes (about 3 cups)
• 2 cloves garlic, minced
• 1 tablespoon olive oil
• 1/2 teaspoon dried oregano
• 1/2 teaspoon dried basil
• Fresh basil or parsley for garnish (optional)

Recommended Equipment

Large pot for boiling pasta, colander, mixing bowl, 9×13-inch baking dish, skillet for sauce, spatula or spoon for stuffing.

Optional Substitutions

• Cottage cheese: Use ricotta for a richer, less tangy filling. The protein will be slightly lower.
• Calabrian chili paste: Substitute with 1–2 teaspoons red pepper flakes or chopped pickled jalapeños. Heat level will vary.
• Mozzarella: Use provolone, fontina, or a dairy-free shreds for a different flavor or dietary need.
• Parmesan: Swap with Pecorino Romano for a saltier, sharper taste.
• Pasta shells: Any large pasta like conchiglie or manicotti works. Adjust cooking time if needed.
• Crushed tomatoes: Use marinara sauce or diced tomatoes (blended) for a chunkier texture.
• Low-fat cottage cheese: Works, but the filling will be less creamy. Add 1 tablespoon of olive oil to compensate.
• Greek yogurt: Mix with a little milk as a cottage cheese replacement—not as thick, but still tangy.

Instructions

1. Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish.
2. Bring a large pot of salted water to a boil. Add the jumbo shells and cook according to package directions until al dente (usually 10–12 minutes). Drain and rinse with cool water to stop cooking. Set aside.
3. While the pasta cooks, make the sauce: In a medium skillet, heat 1 tablespoon olive oil over medium heat. Add the minced garlic and sauté for about 30 seconds until fragrant. Add the crushed tomatoes, oregano, basil, salt, and pepper. Simmer for 5 minutes, then remove from heat.
4. In a large mixing bowl, combine the cottage cheese, mozzarella, Parmesan, Calabrian chili paste, beaten egg, garlic powder, onion powder, salt, and pepper. Mix well until everything is evenly combined. Taste and adjust chili paste if needed.
5. Spread half of the tomato sauce evenly over the bottom of the prepared baking dish.
6. Carefully stuff each cooked shell with about 1–2 tablespoons of the cheese mixture. You can use a small spoon or a piping bag for ease. Place the filled shells open-side up in the baking dish, nestled closely together.
7. Spoon the remaining sauce over the stuffed shells, making sure to cover them lightly. Sprinkle any remaining mozzarella or Parmesan on top.
8. Cover the dish with foil and bake for 20 minutes. Then remove the foil and bake for another 10–15 minutes, until the sauce is bubbly and the cheese on top is melted and lightly golden.
9. Let the dish rest for 5 minutes before serving. Garnish with fresh basil or parsley if desired.

Pro Tips

• Don't overcook the shells: They should be al dente because they will continue to cook in the oven. Overcooked shells become too soft to stuff and may fall apart.
• Rinse with cool water: After draining, rinse the shells under cold water to stop cooking and make them easier to handle.
• Pat shells dry: Moisture on the shells can make the filling slide off. Pat them gently with a clean kitchen towel.
• Spread the filling evenly: Use a teaspoon to fill each shell without overstuffing—too much filling and the shells won't seal properly.
• Layer sauce underneath and on top: This prevents the shells from drying out and adds flavor throughout.
• Use a piping bag for speed: If you have a pastry bag or a zip-top bag with the corner snipped, filling the shells is faster and neater.
• Let it rest before serving: Resting allows the dish to set and makes it easier to serve without falling apart.
• Adjust the heat: Calabrian chili paste varies in spiciness. Start with 1 tablespoon and add more if you like it hotter.
• Use full-fat cottage cheese: Low-fat can be watery. If you use low-fat, drain it in a fine-mesh sieve for 15 minutes before mixing.

Variations and Substitutions

• Vegetable-packed: Add sautéed spinach, mushrooms, or zucchini to the cottage cheese mixture for extra nutrients.
• Meaty version: Brown 1/2 pound Italian sausage or ground turkey and mix it with the filling for a heartier dish.
• White sauce swap: Replace the tomato sauce with a simple béchamel or Alfredo for a creamy, mild version.
• Gluten-free: Use gluten-free jumbo shells (such as brown rice pasta) and ensure the Calabrian chili paste is gluten-free.
• Extra cheesy: Mix in 1/2 cup shredded provolone or fontina for more cheesy goodness.
• Lighter option: Use low-fat cottage cheese, low-fat mozzarella, and skip the Parmesan. The texture will be less rich but still delicious.
• Roasted red pepper: Replace half the chili paste with roasted red pepper purée for a milder, slightly sweet flavor.
• Add herbs: Stir in 2 tablespoons chopped fresh basil or parsley into the filling for a fresh pop.

Storage and Reheating

Fridge

Let leftover stuffed shells cool completely, then transfer to an airtight container. They will keep for up to 4 days in the refrigerator. The flavors often get better overnight.

Freezer

To freeze, assemble the unbaked dish in a freezer-safe baking dish (or portion into individual containers). Cover tightly with foil and freeze for up to 3 months. Thaw overnight in the fridge before baking as directed, adding 10–15 minutes to the covered bake time. You can also freeze baked leftovers in a single layer on a baking sheet, then transfer to a freezer bag.

Reheating

Reheat individual portions in the microwave on medium power for 2–3 minutes, or until hot. For the oven, cover with foil and bake at 350°F (175°C) for 15–20 minutes, or until warmed through. If the shells seem dry, add a spoonful of water or extra sauce before reheating.

FAQ

Can I use ricotta instead of cottage cheese? Yes, you can substitute an equal amount of ricotta. The filling will be richer and slightly less tangy. The protein content will be lower.

How spicy are these stuffed shells? With 2 tablespoons of Calabrian chili paste, they have a moderate heat—about the level of a spicy marinara. For less heat, use 1 tablespoon; for more, add up to 3.

Can I make this dairy-free? Yes, use dairy-free cottage cheese (or tofu ricotta), vegan mozzarella, and dairy-free Parmesan. Bake times remain the same.

Do I have to use jumbo shells? No, you can use any large pasta that can be stuffed, like manicotti or conchiglie. Cooking time may vary.

Can I assemble this ahead of time? Absolutely! Assemble the dish completely, cover, and refrigerate for up to 24 hours. Add 10 minutes to the covered baking time if baking straight from the fridge.

What can I serve with this? A simple green salad with lemon vinaigrette, roasted broccoli, or crusty garlic bread are great sides. It's a complete meal on its own, too.

My shells keep breaking—what's wrong? They may be overcooked. Cook just to al dente, rinse with cool water, and handle gently. Also, underfilling can cause cracking—fill them snugly but not overly full.

Can I use store-bought marinara instead of making sauce? Yes, use 2–3 cups of your favorite marinara. Simmer it with a little extra garlic and dried herbs for a flavor boost if desired.
