1 (16 ounce) package jumbo pasta shells
4 cups large curd cottage cheese
12 ounces mozzarella cheese, shredded
¾ cup grated Parmesan cheese, divided
2 large eggs, lightly beaten
1 pinch garlic powder
1 teaspoon dried oregano
1 teaspoon dried parsley
1 (26 ounce) jar spaghetti sauce
Gather all ingredients.
Preheat the oven to 350 degrees F (175 degrees C).
Bring a large pot of salted water to a boil. Add shells and cook, stirring occasionally, until tender yet firm to the bite, about 8 minutes. Drain, rinse under cold water, and set aside.
Mix together cottage cheese, mozzarella cheese, 1/2 cup Parmesan cheese, eggs, and garlic powder in a large bowl. Rub oregano and parsley between your palms to pulverize them, then stir into cheese mixture.
Stuff cheese mixture into pasta shells.
Spread 1/3 of the spaghetti sauce on the bottom of a 15x10-inch baking dish. Place shells, seam-side up, close together in the dish. Spread remaining sauce on top; sprinkle with remaining 1/4 cup Parmesan cheese.
Bake in the preheated oven until bubbly, 25 to 35 minutes. Let stand 10 minutes before serving.
