Made with only 5 key ingredients, and minimal effort, this easy baked rotini recipe delivers a cheesy, gooey, kid-friendly meal that can feed a large crowd on a budget.
Bring a large pot of water to a rapid boil. Once boiling, add in 1 tablespoon of kosher salt and the rotini noodles. Cook the noodles for 1-2 minutes less than the package suggests--just shy of al dente, stirring occasionally. Drain pasta, reserving ½ cup of the cooking liquid.
Place the cooked rotini in a large mixing bowl. Add the prepared spaghetti sauce, ½ cup of reserved cooking liquid, cottage cheese, and half the mozzarella cheese. Stir to combine, then add the whisked egg into the pasta, mixing again to combine.
Pour the pasta mixture into a large 9-by-13-inch casserole dish or a 3-quart casserole dish and top with the remaining cheese.
Bake uncovered for 30 minutes, or until the cheese is bubbly and the casserole is warmed through.

Notes
Rotini Noodles: Whole wheat, regular, or gluten-free rotini noodles can be used. In place of rotini, feel free to use ziti, rigatoni, or penne noodles. Add Meat: Feel free to add ground beef, sausage, or even pepperoni to this baked rotini for a heartier dish.Cheese: Feel free to use a mixture of mozzarella and parmesan or even an Italian-blend of cheese. Spices: Feel free to add up to 1 teaspoon each of garlic powder, dried oregano, and Italian seasoning. Cottage Cheese: Choose cottage cheese by ingredients, not just fat content. For the smoothest, creamiest results, use 2% or 4% small-curd cottage cheese made with simple ingredients (milk, cream, and salt). Do not use fat-free cottage cheese. In place of cottage cheese, ricotta cheese can be used. Egg-Free: Simply omit the egg from the casserole and be sure your noodles are egg-free. Storage: Allow the pasta bake to cool, then store in an airtight container in the refrigerator for up to 3 days. Reheat on a heat-safe plate, covered with a damp paper towel, in the microwave in 60-second intervals until warmed through. Make-Ahead: Pasta Bake can be assembled up to baking, covered, and refrigerated up to 24 hours in advance. Remove from the fridge while the oven preheats and bake at 350 degrees F for 50 minutes.Freeze the Casserole: Assemble the rotini casserole up to baking in a freezer-safe/oven-safe baking dish. Cover with 2 layers of foil and freeze for up to 2 months. To bake from frozen, remove one layer of foil and bake at 350 degrees for 1 hour. Remove foil and bake for an additional 15-20 minutes, or until warmed through.
