Here’s What You’ll Need
You will only need a few simple ingredients for this keto cheeseburger casserole recipe. All the exact measurements of the ingredients are listed in the recipe card below. Here’s what you’ll need to cook this recipe:
- Ground beef. You can choose any ground beef; whether you prefer extra lean or leaner, any kind is fine. Alternatively, you can also use ground pork, ground chicken, or ground turkey instead. But if you change any of the ingredients, remember that the number of calories and fat of the cooked meal will be different.
- Eggs. It's okay to skip this ingredient. But I like to add it into the casserole because it gives more flavor, and it holds everything together.
- Sauce. For the casserole sauce, you'll need to combine some heavy cream, tomato paste, and some mustard. Just be careful when choosing the tomato paste and make sure that it is sugar-free.
- Bacon. I can't imagine eating a burger without bacon. So, this ingredient is a must for this cheeseburger casserole. You'll need to chop it up and fry it in a pan until crisp before adding it into the low-carb cheeseburger casserole.
- Onion. Simply chop up the onion and fry it in the fat that was left after cooking the bacon.
- Pickled cucumber. This is my favorite ingredient since it adds the needed flavor.
- Tomato. If you like tomatoes on your cheeseburger as much as I do, then you must include this ingredient into the keto cheeseburger casserole.
- Mozzarella cheese. A cheeseburger without cheese is like a sausage patty without meat. The more mozzarella cheese you add into the casserole, the better.
- Seasoning. If you don't like to add any spices or herbs to your meals, you can skip this part. Just adding salt and pepper will be enough. But I prefer my keto cheeseburger casserole with some garlic powder, pepper flakes, and the Grill Mates Hamburger Seasoning.
What Baking Dish to Use
For this recipe, I chose an 8x8-inch baking dish. The keto cheeseburger casserole turned out with the perfect thickness. If you have a slightly larger dish, you can use it, but then the casserole will be a bit thinner.
When I have some friends over, I always make twice the amount of cheeseburger casserole. In that case, I simply double all of the ingredients and use a 13x9 casserole dish instead.
How to Store the Casserole
Cover the keto cheeseburger casserole with some plastic wrap or place it in a container before storing it in the refrigerator. You can keep it in the fridge for up to 4 days. Whenever you want to eat it, simply reheat it in the microwave.
Or, you can also freeze this meal. It’s simple—fully cook the cheeseburger casserole, cover it with plastic wrap, then place it in the freezer. Before serving, let the dish thaw in the fridge or at room temperature and then heat in the microwave for a minute or two before serving.
Just like the traditional burgers are best with lettuce, the same applies to this cheeseburger casserole. Since burger buns are definitely a no when it comes to eating keto, simply adding some fresh lettuce when serving this casserole will make it taste as close to a burger as it can get.
Other ways to serve this low-carb cheeseburger casserole is with some cauliflower rice on the side. It’s a great way to add more veggies to your diet.
Or, you can also serve the casserole with some guacamole on the side. I love it and can eat it with almost anything, and it tastes perfect with this cheesy casserole.
