Easy Italian Sausage and Rigatoni

Step 1
Bring a large pot of lightly salted water to a boil. Cook rigatoni in the boiling water, stirring occasionally until tender yet firm to the bite, about 12 minutes. Drain and set aside.

Step 2
Meanwhile, preheat the oven to 350 degrees F (175 degrees C). Grease a large baking dish.

Step 3
Cook sausage and onion in a large skillet until meat is no longer pink and onions are translucent, 5 to 7 minutes.

Step 4
Combine spaghetti sauce, cottage cheese, 1 cup mozzarella cheese, Parmesan cheese, eggs, parsley, Italian seasoning, basil, salt, and pepper in a large bowl. Add sausage and onion mixture; stir until well combined. Add pasta and carefully mix until well incorporated. Transfer to the prepared baking dish and cover.

Step 5
Bake in the preheated oven for 45 minutes. Remove from the oven, top with remaining mozzarella, and bake, uncovered, until cheese is melted, about 15 minutes.
