We all crave cheeseburgers on our keto journey, right? While you can make amazing keto cheeseburgers and hamburgers using my keto burger buns recipe, there is a quicker option. This keto hamburger casserole is the trick to fix all your (cheese)burgers cravings and, meal prep a week of easy keto breakfasts without cooking every morning!
Keto cheeseburger casserole ingredients
All you need to make this easy low-carb keto cheeseburger casserole are few simple ingredients. Of course, jump to the recipe below for the full measurements of each ingredient. But first, let us see how to choose the best ingredients for this easy keto casserole.
Ground beef – choose good-quality beef, grass-fed if possible.
Burger spices – most store-bought ready-made burger spice mixes contain sugar. That’s why this keto recipe doesn’t use this option. Instead, you can mimic burger flavors using a combination of garlic powder, onion powder, paprika, and beef broth.
Grated cheddar – any kind of cheddar cheese works well, use your favorite. In case you are wondering, cheddar has only 0.7 grams of net carbs per ounce, making it a very low-carb dairy product.
Salt and pepper – seasoning casserole is the key to making the best keto cheeseburger casserole.
Mayonnaise – not all mayonnaise are keto-friendly, the best option is avocado oil mayonnaise. If you can’t find this in your store, replace by the same amount of sour cream or cream cheese.
Mustard – yellow or Dijon mustard, as you like, both are keto-friendly.
Pickles– normal cheeseburgers are hamburgers with cheese and pickles (gherkins in the UK). So to make a proper cheeseburger casserole, you need a few slices of pickles or we should call this dish a keto hamburger casserole! Of course, if you are not a fan of pickles, swap for the same amount of fried bacon pieces, a keto bacon cheeseburger casserole is amazing too!
A super easy keto breakfast casserole
We are all looking for keto breakfasts without eggs. I mean, not totally egg-free but a breakfast that doesn’t look like an omelet, fried eggs, or scrambled eggs.
Well, this easy keto casserole is the best egg-free keto breakfast to start the day with only 3 grams of net carbs.
I recommend preparing your casserole the day before and rewarming every morning in the microwave, oven, or saucepan.
Step 1: Brown the meat
The key to making a tasty keto ground beef casserole is to brown the meat in olive oil. Warm a large skillet over medium-high heat, start browning the meat by breaking/crumbling the beef apart with a spoon to cook evenly.
The meat is cooked when it is not pink anymore.
Step 2: Drain the meat
To avoid a runny casserole it is important to remove the liquid from the skillet. Then, return the meat into the skillet and cook again with the mayonnaise, cream cheese, or sour cream.
Step 3: Pick the correct casserole dish size
We all love our casseroles differently. If you love a thick beef layer, to mimic a double cheeseburger, then use a 9-inch x 9-inch baking dish as seen in this post.
For a thinner layer of ground beef use a 9-inch x 13-inch. Spread the beef mixture evenly over the pan, add pickle slices, and set aside.
Note that this won’t impact the carb per serve because whatever the size of the dish you use, you divide the entire dish into 9 portions of the same size.
Since you spread the ingredients evenly into the baking dish, the net carbs per serve will remain the same.
Step 4: Making the cheeseburger sauce
Prepare the cheeseburger sauce in a separate mixing bowl. Beat the eggs with heavy cream, sugar-free ketchup, mustard, and shredded cheddar. Pour this sauce evenly over the baking dish. The larger the dish is, the thinner the layer of sauce will be.
Step 5: Bake for 15 minutes
Bake the casserole with the remaining shredded cheddar on top, until melted and broiled.
How to customize my keto casserole?
There are so many options to tune this recipe and create a variety of new keto casseroles.
Keto cheeseburger cauliflower casserole – replace 1/2 lbs of ground beef by the same amount of cauliflower rice.
Keto cheeseburger bacon casserole – simply add bacon – fry 1/2 lbs of fried bacon pieces and arrange on top of the cooked ground beef in the casserole dish.
Vegetables – you can add 1/2 cup of diced red bell peppers, along with the onions.
How to eat cheeseburger casserole?
Of course, you can serve this casserole plain, it is delicious. But what about turning the cheeseburger experience further by serving your casserole on top of lettuce and thin slices of tomatoes.
This will bring out all the cheeseburger flavors and if you add 50g (1.8 oz) of each ingredient, one serving will contain 5.2 grams of net carbs instead of 3 grams of net carb, if served without these keto vegetables.
