How to Cook High Protein Stuffed Shells

Preheat your oven to 375°F (190°C). Spread 1 cup of marinara sauce evenly on the bottom of a baking dish to enhance the flavor.
Bring a large pot of salted water to a rolling boil. Add the jumbo pasta shells and cook until al dente, about 9 minutes. Drain and cool them on a baking sheet to prevent sticking.
In a large pan over medium heat, warm a splash of olive oil. Add the diced onion and sauté for about 3 minutes until softened. Stir in minced garlic and cook for an additional minute until fragrant.
Crumble the ground turkey into the pan, adding Italian seasoning, kosher salt, black pepper, and red pepper flakes. Cook until the turkey is browned and fully cooked, about 5 to 7 minutes.
Incorporate the frozen chopped spinach into the turkey mixture, cooking until the spinach is wilted and combined.
In a separate bowl, mix the cottage cheese, 1 cup of mozzarella cheese, and parmesan until well combined and season with salt.
Fold the cheese mixture into the turkey and spinach filling carefully.
Take the cooled pasta shells and stuff them generously with the turkey mixture. Place the filled shells in the baking dish, side by side.
Pour the remaining marinara sauce over the stuffed shells and sprinkle the remaining mozzarella cheese on top for a bubbly finish.
Bake in the preheated oven for 25 minutes until heated through and golden on top. Optionally, broil for a few minutes for an extra crispy finish.
Garnish with fresh basil before serving for added color and flavor.

Serve with a white sauce or different marinara varieties, such as a spicy arrabbiata.

Cook’s Notes and Secrets

Ensure the pasta shells are fully cooked but still firm, as they will continue to cook in the oven.
Don’t overstuff the shells; a generous spoonful is all you need.

For even cooking, make sure the shells are arranged evenly in the baking dish.
Use a thermometer to ensure the filling reaches an internal temperature of 165°F (74°C).
