How To Make A Keto Hamburger Casserole

To prepare this casserole, start by cooking 24 ounces of frozen cauliflower rice in the microwave according to the instructions on the bag. Once cooked, place the cauliflower rice in a small bowl and set it aside.

Then, in a large skillet over medium-high heat, brown the ground beef, breaking it up and sprinkling it with baking soda and seasonings. If using baking soda to tenderize the meat, allow it to sit for 15 minutes.

Cook the beef until browned, breaking the meat mixture into pieces with a spatula. Transfer the browned ground beef to a 13×9-inch baking dish.

To make the tomato sauce, cook onions, peppers, and garlic with olive oil in a small pot over medium-high heat until the vegetables are tender and translucent.

Add canned tomatoes, dry herbs, and seasoning, then simmer the sauce for about 5 minutes before setting it aside.

Preheat the oven to 350 degrees. Layer the casserole by adding the ground beef to the bottom of the baking dish, followed by the cooked cauliflower rice, and spread it evenly.

Next, pour the tomato sauce over the cauliflower rice layer and spread it evenly, then sprinkle shredded cheddar cheese over the sauce. Bake the casserole for 35–45 minutes until the cheese melts and lightly browns around the edges.

Finally, sprinkle the top of the casserole with freshly chopped parsley and serve it hot.

Leftovers can be refrigerated for up to three days or frozen in an airtight container for up to three weeks.

Tips To Make A Low-Carb Cheeseburger Casserole

Something to keep in mind when making this hamburger keto casserole is the use of lean ground beef.  I opted for 85% lean ground beef because it prevents the casserole from being too greasy when served.

I promise you won’t miss the flavor of the fat since it’s a casserole that is loaded with flavor.

Another thing to keep in mind is that, although I used frozen cauliflower rice, if frozen cauliflower isn’t an available option for you, refer to cauliflower rice to make your own.

How To Tenderize Ground Beef With Baking Soda

When preparing ground beef, I enjoy sprinkling a small amount of baking soda over the raw ground meat before cooking and letting it rest for 15 minutes. Why? It helps to tenderize the ground beef.

The addition of baking soda aids in breaking down the meat quickly, preventing large clumps of beef. The general guideline is to add 1/4 teaspoon per pound of beef, which is why I included 1/2 teaspoon in the recipe.

I find this clever trick particularly useful when making low-carb ground beef recipes, as it accelerates the cooking process and ensures the ground meat cooks more evenly.

It’s important to note that while this step is entirely optional, omitting it will result in a slightly longer cooking time for the ground beef.

Recipe Variations

This low-carb hamburger casserole is easy to customize for other flavor options. Here are a few suggestions to try:

• Add a few dashes of hot sauce to the tomato sauce layer for a little spice.
• Add a few crumbled slices for a keto bacon cheeseburger casserole.
• A layer of chopped dill pickles if your family likes pickles.
• Swap out the shredded cheddar cheese for mozzarella cheese or any other easy-melting cheese.
• Swap out the ground beef for ground turkey or even ground chicken.

What To Serve With A Cheeseburger Keto Casserole?

What’s especially nice about a low carb casserole like this is that it’s a hearty meal on its own. Dinner time just got easier since no side dishes were needed to round out the meal.

However, if you want to stretch the meal further, there are a few sides that work well with the flavorings of this keto ground beef casserole.

• Keto Green Beans Almondine
