Ingredients

20–24 jumbo pasta shells
2 cups low-fat cottage cheese (2%)
1 cup part-skim mozzarella, shredded, divided
1/2 cup grated Parmesan, divided
2 large egg whites (or 1 whole egg)
2 cups marinara sauce (low-sugar if preferred)
2 cups fresh spinach, chopped (or 1 cup frozen, thawed and well-squeezed)
2 cloves garlic, minced
1 tablespoon fresh basil, chopped (or 1 teaspoon dried)
1 teaspoon dried oregano
1/4 teaspoon red pepper flakes (optional)
Salt and black pepper to taste
Olive oil spray or 1 teaspoon olive oil (for the baking dish)

Instructions

Cook the shells: Boil in salted water until just shy of al dente. Drain and rinse with cool water so they’re easier to handle.Set aside on a tray.
Prep the filling: In a bowl, stir cottage cheese until slightly creamy. Add 1/2 cup mozzarella, 1/4 cup Parmesan, egg whites, garlic, basil, oregano, red pepper flakes, spinach, and a pinch of salt and pepper. Mix until combined.
Taste and adjust: Add more salt, pepper, or herbs as needed.The filling should be well-seasoned since the pasta is mild.
Prepare the pan: Lightly oil a 9×13-inch baking dish. Spread 1 cup marinara across the bottom.
Stuff the shells: Spoon about 2 tablespoons of filling into each shell. Nestle stuffed shells into the sauced dish, open side up.
Top and cover: Spoon the remaining marinara over the shells.Sprinkle with the remaining 1/2 cup mozzarella and 1/4 cup Parmesan.
Bake: Cover with foil and bake at 375°F (190°C) for 20 minutes. Uncover and bake 10–15 minutes more, until bubbly and lightly golden.
Rest and serve: Let stand 5–10 minutes. Garnish with fresh basil or parsley and a crack of black pepper.

Keeping It Fresh

Fridge: Store leftovers in an airtight container for 3–4 days.
Freezer (unbaked): Assemble in a freezer-safe dish, wrap well, and freeze up to 2 months.Bake from frozen at 350°F (175°C) for 45–60 minutes, covered, then uncover to brown.
Freezer (baked): Cool completely, portion, and freeze. Reheat covered at 350°F until hot.
Moisture tip: Add a splash of water or extra sauce when reheating to keep shells from drying out.

Pitfalls to Watch Out For

Dry bake: Ensure there’s sauce on the bottom and over the top so the shells steam and stay tender.

Variations You Can Try

Herb & lemon: Add lemon zest and extra fresh parsley for brightness.
Veggie boost: Fold in sautéed mushrooms, roasted peppers, or zucchini.
Meaty version: Add lean ground turkey or chicken sausage to the sauce for even more protein.

FAQ

Can I use ricotta instead of cottage cheese?

Yes. Use the same amount of part-skim ricotta. For a lighter version, keep the egg whites and spinach as written.

How do I make the cottage cheese smoother?

Blend it in a food processor or with an immersion blender for 10–20 seconds before mixing.

It becomes silky and more ricotta-like.

What’s the best store-bought sauce for this?

Choose a marinara with simple ingredients, low added sugar, and robust tomato flavor. Brands with basil and garlic notes work especially well.

Can I assemble this ahead?

Absolutely. Assemble up to 24 hours in advance, cover, and refrigerate.

Add 5–10 extra minutes to the covered bake time.

How can I add more protein?

Stir in cooked ground turkey to the sauce, or add a few tablespoons of grated Parmesan to the filling. You can also use higher-protein cottage cheese.
