My keto cheeseburger casserole features seasoned ground beef, low carb macaroni, and layers of gooey melted cheese. It has all the flavors and textures of a cheeseburger, without all the carbs. Topped with burger sauce and pickles, it’s a family favorite we crave on repeat!

My family’s favorite cheeseburger casserole

When life gets busy and you need dinner fast, casseroles are a lifesaver, and this cheesburger casserole is my go-to.
It packs all the best parts of a juicy cheeseburger, minus the bun, and swaps in keto macaroni noodles that taste just like the real thing (I tested every low-carb noodle I could find to get it right).
It’s kid-approved, customizable, and so good that even my non-low-carb family requests it on repeat. Bonus? It’s freezer-friendly, so make a double batch and stash one away for an easy weeknight win.
Key Ingredients
This isn’t the full list of ingredients, but just some notes on the main ones. Find the printable recipe with measurements below.
- Low-carb macaroni. I tested Kaizen low-carb fusilli, Pete’s low-carb pasta, Carpe Diem penne, and also Aviate keto pasta. Pete’s low-carb penne came out on top and out of these four, tasted the most similar to pasta. If there’s a particular low-carb pasta you enjoy, you can use that.
- Bacon. Because why not make a keto bacon cheeseburger casserole?!
- Ground beef. I used lean ground beef, but if you prefer higher-fat cuts, drain the excess fat before adding it to the casserole.
- Tomato sauce. Think of this as the ketchup to the burger.
- Worcestershire sauce. Just a dash adds a depth of flavor.
- Shredded cheddar cheese and mozzarella cheese. A combination of both cheeses gives the casserole the perfect gooey, melty texture.
- Cheeseburger toppings. Optional, but you can top the casserole with chopped dill pickles, shredded lettuce, yellow mustard, sugar-free ketchup, or sugar-free BBQ sauce.
Recipe variations
- Swap the meat. Instead of ground beef, use ground turkey, ground chicken, or even plant-based ground meat.
- Add more veggies. Like cauliflower rice, diced tomatoes, chopped mushrooms, or sliced bell peppers.
- Make a creamier sauce. Add a splash of heavy cream or softened cream cheese.
- Play around with spices. Give it some heat with red pepper flakes, smoked paprika, or even my keto taco seasoning.
How to make keto cheeseburger casserole

Step 1- Make the sauce. Add oil to a large skillet over medium-high heat. Once hot, add the onion and chopped bacon and cook for a further minute. Add the ground beef and cook until no longer pink. Add the tomato sauce to the pan and cook for another minute.

Step 2- Combine. Add the cooked pasta to the ground beef mixture. Stir in half the cheeses and combine.

Step 3- Bake. Transfer the mixture to the greased casserole dish. Top with the remaining cheese and bake for 10-15 minutes until the cheese is bubbling.

Step 4- Top. Rest the casserole for a few minutes, add any cheeseburger toppings, and serve.

Arman’s recipe tips
- Prepare it up to four days in advance. Assemble the casserole, cover it, and refrigerate it until you’re ready to bake. Let it come to room temperature for 20 minutes before baking.
- If possible, use freshly grated cheese. Trust me, it melts way smoother and makes for a creamier mixture.
- Adjust the consistency. If the sauce is too thick, add 1-2 tablespoons of pasta water to thin it out.
- Taste as you go, and add any seasonings or salt as needed.

Notes
- Keto pasta brands: I like using Pete’s low carb pasta, which is available on Amazon (usually in a 6-pack). If you can’t find that, the next best option is Kaizen pasta. Of course, if there’s a brand of keto pasta you enjoy, feel free to use that.
