How to Make Baked Rotini

The following tips are provided to help you achieve perfect results. You will find the ingredient quantities and detailed instructions in the recipe card at the bottom of this post.

Cook Rotini Noodles. Cook the noodles in heavily salted boiling water until just shy of al dente--about 1-2 minutes less than the package suggests. The pasta will finish cooking through in the oven. Drain pasta, reserving ½ cup cooking water.
Combine Ingredients. In a large mixing bowl, combine the cooked rotini with the spaghetti sauce, half of the cheese, reserved cooking liquid, and cottage cheese. Pro Tip: Add the reserved cooking liquid to the empty jar of spaghetti sauce and give it a shake before adding to the mixture--that will get out every tidbit of sauce.
Add Egg. It is best to add the whisked egg AFTER combining the other ingredients with the cooked rotini. That will cool the pasta down enough to ensure your egg won't scramble when it hits the hot pasta.
Assemble Pasta Bake. Pour the rotini mixture into a large baking dish and top with the remaining cheese.
Bake. Bake until the cheese melts and the pasta is warmed through.

Kristen's Key Tips for Baked Rotini

Rotini Noodles are Best. Rotini noodles are easy to find, grasp the sauce perfectly, and stay soft during baking. Other suitable options are rigatoni, corkscrew, or penne.
Pick a Quality Sauce. Because this recipe uses so few ingredients, be sure you start with quality spaghetti sauce or marinara.
Reserve the Cooking Liquid. Adding a bit of the starchy, salty cooking liquid from the pasta will help the sauce adhere to the noodles, while flavoring it as well.
Grate the Cheese Yourself. This recipe is designed to be EASY! But if you can, take a few minutes to grate the cheese rather than relying on bagged cheese for the creamiest of melts.
Make it Your Way! Add cooked and crumbled Italian sausage, baked meatballs, or ground meat, amp up the seasonings with the addition of garlic powder and Italian seasoning, omit the egg, swap out the cottage cheese for ricotta cheese--you get the idea.

Storage & Make-Ahead Instructions

This easy pasta bake is almost always found stashed in my freezer. It makes a great go-to meal for busy nights for my family, but it is also a great meal to take to a friend or family in need of a comforting home-cooked meal.

Leftover Pasta: Let the pasta cool slightly, place in an airtight container, and store in the refrigerator for up to 3 days. Reheat in the microwave on a heat-safe, covered with a damp paper towel until warmed through.
Assemble & Freeze: To prepare pasta in advance, assemble pasta up to baking in a freezer-safe baking dish. Cover well with 2 layers of foil and freeze for up to two months. To bake from frozen, remove 1 layer of foil and bake at 350 degrees F for 60 minutes covered, then uncover and bake for an additional 10-15 minutes, or until warmed through and cheese is melted.
Prep Up to 24 Hours in Advance: If you plan to bake this rotini casserole within 24 days of assembling, there is no need to freeze it. Simply prepare the casserole up to baking. Place the prepared rotini in a baking dish, cover it with plastic wrap, and refrigerate it for up to 24 hours. When ready to bake, remove the baking dish from the fridge while the oven is preheating, remove the plastic wrap, and bake at 350 degrees F for 45-50 minutes or until warmed through.
