The Easiest Pasta Bake
When I need an easy meal that is both delicious and cozy that my entire family loves, I find myself turning to this baked rotini recipe time after time.
And if you love pasta, you too, will adore this baked rotini.
It only requires a handful of inexpensive ingredients and delivers lasagna with cottage cheese vibes without the hassle. And with 22 grams of protein per serving and no added meat, it's a wholesome, affordable meal perfect for busy nights or even special occasions.
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.

My eleven year old grandson and I made this as he loves pasta dishes. It was easy enough for him to make, and it was delicious. We did add ground beef, green pepper and onions. Made enough for leftovers, Will make again.
I love that you made this with your grandson. What a precious memory to go along with your delicious dinner. Thanks for sharing.
I made it exactly as written and it tasted great. It makes for a very easy weeknight meal.
YAY! I love hearing you enjoyed and found this recipe easy to make. And appreciate you taking the time to leave a review, Jennifer.
First off NO spaghetti should be without meat or mushrooms disguised as meat! 😆 I add ground chicken,fire roasted tomatoes and mushrooms and use Banza or Brami pasta to make it keto. I also add parmesan cheese. Other than that I make this by the book and it's a hit every time! Thank you for a truly easy quick recipe!
Love that you enjoy this (and thank you for sharing your additions!)
A wonderful recipe, creamy, easy to make and extremely well explained.
Thanks Kristen
So happy to hear you enjoyed, Ligia! I appreciate you sharing.
Looks and sounds so good.
I made this recipe for me and my elderly parents last night. Not only was it really easy and delicious, we have lots of leftovers to continue enjoying on at both homes. I did add a pound of ground beef to make it a heartier meal, as you suggested, and goodness, is it yummy! My parents kept saying so.
Delicious! Glad you and your parents enjoyed!
Thank you so much for sharing! We love this recipe at our house and make it all the time. If I were to freeze it to eat later, would I bake it for 30 min before freezing or just freeze and bake after when ready to eat?
Hi Hayley! You can assemble the casserole in a freezer-safe dish up to baking. Let cool, cover tightly with foil, and freeze. From freezer, bake at 350 degrees for 45 minutes covered, and then uncovered for 15 additional minutes.
