Unlike other keto casseroles, this casserole has layers like a cheeseburger! The base is similar to my loaded cauliflower casserole, while the beef and topping layers are similar to a big mac casserole. You’re going to love it!
Ingredients & Substitutions
Here I explain the best ingredients for a cheeseburger keto casserole, what each one does in the recipe, and substitution options. For measurements, see the recipe card.
Base Layer:
Avocado Oil – For your pan. Olive oil or any other neutral cooking oil works. Cauliflower – Some people make cheeseburger casserole with pasta, but I used cauliflower rice for a healthier option that’s just as comforting. You can also use store-bought riced cauliflower (fresh or frozen), or use one of my roasted cauliflower recipes as the base instead. Sea Salt Shredded Cheddar Cheese – Pairs with the riced cauliflower for a cheesy layer. You can use any cheese you’d serve on a burger, such as mozzarella, Swiss, or Monterey Jack. Heavy Cream – Makes it rich and creamy. You could also use half and half, or coconut cream.
Beef Layer:
Ground Beef – I typically use 85/15 grass-fed beef, which is flavorful without being too greasy, but use any variety you like. You could even sub ground chicken or ground turkey for lighter options. Sea Salt & Black Pepper
Top Layer:
Ketchup – My fave is homemade sugar-free ketchup, but I like this store-bought brand when I’m in a hurry. Mustard – I used yellow mustard for classic hamburger flavor, but Dijon mustard works, too. Shredded Cheddar Cheese – For a gooey topping.
How To Make Keto Cheeseburger Casserole
This section shows how to make low carb cheeseburger casserole with step-by-step photos and details about the technique, to help you visualize it. For full instructions with amounts and temperatures, see the recipe card.
Storage Instructions
Store: Wrap the baking dish tightly with plastic wrap or transfer the casserole to an airtight container. Store in the fridge for up to 4-5 days. Meal prep: Make the casserole, and then portion it into individual containers in the refrigerator for easy lunches. Reheat: Simply pop bowls of individual portions in the microwave for a minute or two, until warm. Alternatively, you can reheat the entire dish in the oven at 350 degrees F for about 15-20 minutes. Freeze: Cover the keto cheeseburger casserole with plastic wrap followed by foil, then keep in the freezer for up to 3 months. You can reheat right from frozen, but it’s much faster if you thaw in the fridge overnight first. You can also freeze individual portions instead to enjoy on meal at a time.
What To Serve With Keto Cheeseburger Casserole
This keto hamburger casserole is a complete meal on its own, but like a burger, you may want a side or two. Here are some ideas:
Low Carb Fries – Make it a classic fast-food meal by pairing this keto hamburger casserole with a side of keto french fries or jicama fries. If you want a veggie twist, try zucchini fries. Salad – I love to pair this casserole with a simple arugula salad, but you can pair it with any of my keto salad recipes for a quick and easy side dish. Roasted Veggies – Serve keto cheeseburger casserole with a side of roasted vegetables like broccoli, or for extra comfort food, cheesy keto brussels sprouts. Fruit – For a light and refreshing side, simply serve this dish with a side of keto fruit. Dessert – Don’t forget dessert! I like to make a quick and easy keto pudding, but any of my keto desserts would be delicious.
