Ingredients
Gather your cheese grater and let’s cook! You can have this tasty keto Cheeseburger Casserole with dill pickles ready to enjoy in approximately 40 minutes!
For the creamy cauliflower base:
- Cauliflower – A medium-sized head is ideal. Fresh cauliflower will yield the best results for this recipe.
- Heavy whipping cream – For a silky smooth cauliflower mash.
- White cheddar – You can substitute with yellow cheddar, but it will change the color of your mash.
- Egg – A single egg to help bind the mash together.
For the beefy layer:
- Ground beef – Lean ground beef works best so there’s no need to drain excess fat.
- Onion powder – To reduce the carb content without sacrificing flavor.
- Garlic powder – For that essential garlic kick!
- Salt and pepper – For seasoning the beef perfectly.
- Cream cheese – This adds a nice creaminess to the beef layer.
- Worcestershire sauce – Enhances the flavors in the cheeseburger layer.
- Ketchup – Opt for your preferred sugar-free variety.
- Cheddar cheese – Shred your own to avoid any starchy anti-clumping agents found in pre-shredded cheeses.
For the topping:
- Yellow mustard – Regular hot dog mustard works just fine.
- Sour cream – Use full fat for best flavor.
- Pickles, red onions, and diced tomatoes – Optional toppings that add extra flavor, texture, and color.

How to Make Keto Cheeseburger Casserole
- Chop the cauliflower into florets, then place it in a bowl with 1/4 cup of water and cover with plastic wrap. Microwave it on high until tender, roughly 10 minutes.
- Drain the cooked cauliflower and puree it with the cream, egg, and white cheddar cheese until it is smooth. Set aside.
- Brown the beef along with the onion and garlic powders, salt, and pepper. Dispose of any excess fat.
- Lower the heat and mix in the cream cheese, stirring until it melts.
- Mix in the Worcestershire sauce and sugar-free ketchup and adjust seasonings as needed.
- Spread the mashed cauliflower on the bottom of a 9×9 (or comparable) casserole dish.
- Top with the ground beef mixture and sprinkle cheddar cheese on top.
- Bake covered with foil at 375°F for about 15-20 minutes or until heated through and bubbly.
- Finally, garnish with diced pickles, tomatoes, and onions—classic cheeseburger flavors—and enjoy!
Chef Jenn’s Tips
- Depending on your casserole dish size and the cauliflower’s size, you might not end up using all of it. Feel free to save any leftover for another meal—just remember to cook it thoroughly since it contains raw egg.
- Your beef mixture should be creamy, not soupy. Take care to drain excess fat before adding the cream cheese.
- Don’t skip the garnishes—they add significant flavor and lift the dish!
- If mashed cauliflower isn’t your favorite, feel free to skip that layer and serve your casserole with any vegetable sides you enjoy, like Green Beans Almondine with Bacon or bacon-wrapped asparagus.
