What Is a Keto Cheeseburger Casserole?

Keto cheeseburger casserole is an easy alternative to classic low-carb burgers that can be prepared in 30 minutes and satisfies for a long time.

The high-fat recipe contains hardly any carbohydrates and is ideal for a ketogenic diet.

The great thing about casseroles is that they require little effort. Pack a few ingredients into a casserole dish, pop it in the oven, and dinner is ready in minutes.

This keto casserole is made with juicy ground beef topped with melted cheese. Fans of the bacon cheeseburger can also top it with crispy bacon. Both kids and adults love this simple dish.

The tasty combination of ingredients rich in healthy fats will unleash a symphony of flavors that will leave you wanting more.


  • Ground beef: I always use ground beef for an authentic cheeseburger flavor. Stay away from low-fat ground beef when following a ketogenic diet.
  • Butter: Grass-fed butter adds extra flavor when sautéing onions and garlic.
  • Onion: No cheeseburger is natural without the zesty onion flavor.
  • Garlic: It adds extra flavor to this keto casserole.
  • Cheese: I prefer cheddar for cheeseburger recipes, as this cheese adds an extra tangy flavor. You can use another cheese of your choice instead.
  • Pickles: Read labels, ingredient list, and nutritional values. Some pickles hide high amounts of sugar. I prefer dill pickles, but you can also use jalapenos if you like them hotter.
  • Mustard: Dijon mustard is the only mustard traditionally made without sugar. To be safe, check the nutritional information as well.
  • Ketchup: This recipe uses organic unsweetened ketchup from Primal Kitchen. It is the only keto-friendly ketchup without unhealthy additives I know.
  • Mayonnaise: I use only homemade keto mayo with olive oil, which you can make in a minute. Ready-made mayo consists of pro-inflammatory seed oils that prevent you from losing weight. Optionally, you can buy mayo from Primal Kitchen, which uses avocado oil instead.


  • For a bacon cheeseburger casserole, add 7 oz of diced bacon to the ground beef before you stuff it into the casserole dish.
  • If you like it spicier, add ½ teaspoon of chili powder.
  • Some people like to add an egg to the meat mixture to help it hold together. You can experiment with 1-3 eggs and find out how it tastes best to you and your family.
  • If you want a creamier casserole, add ¼ cup of cream when you top the ground beef with cheese.
  • You can substitute some or all of the ground beef with sausage, ground chicken, or ground turkey.
