Low-Carb Ground Beef and Cauliflower Casserole

WHAT IS GROUND BEEF AND CAULIFLOWER CASSEROLE?

Low-carb ground beef and cauliflower casserole can be described (by me, at least) as lasagna without the sauce and the carbs. The use of Italian spices gives it a very delicious, Italian flavor while changing up a few ingredients.

Don’t misunderstand, this isn’t meant to be a lasagna replacement.

It is, however, a delicious dish that is something different than you make on a consistent basis. It’s meaty, cheesy, and delicious!

LOW-CARB GROUND BEEF AND CAULIFLOWER CASSEROLE INGREDIENTS

Before you try to make this recipe, you’ll want to make sure to have the following ingredients on hand.

  • 1 lb ground beef, fat content of choice
  • 1 cup sour cream
  • 1 package (10 ounces) frozen cauliflower rice
  • 8 ounces shredded Italian blend cheese
  • 1/2 small yellow onion, chopped
  • 3 cloves garlic, minced
  • 1 tsp Italian seasoning
  • 1/2 tsp paprika
  • salt and pepper, to taste

After you have all of this, you’re set and ready to cook!

HOW TO MAKE GROUND BEEF CASSEROLE

  1. Begin by browning beef (fat content of choice) in a non-stick skillet and a meat chopper
  2. While the beef is browning, preheat your oven to 400˚F
  3. Remove your beef from the pan and add the chopped onions to the leftover beef fat; cook until soft
  4. Stir in garlic and cook for around 30 seconds
  5. Drain beef fat from skillet, if desired, using a slotted spoon to reserve onions and garlic
  6. Add beef to the cooked onions and garlic in the skillet, adding spices; Italian seasoning, paprika, and salt and pepper, to taste
  7. Cook the packaged cauliflower rice, following package directions
  8. In a 9×13 baking dish, combine cooked cauliflower rice and sour cream; add salt and/or pepper if you wish
  9. Form the cauliflower mixture into a layer and spoon the beef mixture on top
  10. Cover with Italian cheese (or cheese of choice)
  11. Bake for 20 – 25 minutes until the cheese is bubbly
  12. Remove from the oven, serve, and enjoy!

WHAT KIND OF GROUND BEEF SHOULD I USE?

Ideally, for a low-carb or keto diet, you want to aim for using higher-fat meats. Generally, a 70/30 ground beef would be the best for a recipe such as this.

Fatty meats, however, do cook down a lot more since there is more fat to cook out. While this isn’t a huge deal, that simply means however much you’re using doesn’t go as. far.

For instance, one pound of 70/30 ground beef might cook down to 3/4 of a pound or less.

Ground beef that is lower in fat will end up being more meat and less fat after browned but is more expensive.

Really, the choice is yours.

STORING LEFTOVER GROUND BEEF CASSEROLE

Storing your leftover ground beef and cauliflower casserole is super easy and simple!

As we always suggest, use glass storage containers for containers that are not only versatile but can be used in the oven and microwave as well.

Obviously, you can use whatever storage containers you may have on hand.

Place the leftovers into the refrigerator where they can stay for 4 – 5 days. If you don’t eat them within that time frame, it’s probably best to discard them.

REHEATING CASSEROLE LEFTOVERS

Reheating this ground beef casserole couldn’t be easier! There are a couple of quick ways you can reheat your leftovers.

REHEATING IN THE MICROWAVE

The quickest and easiest way to reheat your leftover casserole is in the microwave. To do this, simply spoon out the amount you are wanting to reheat onto a plate or into a bowl and place it in the microwave.

Microwave on high for 1 minute, stirring at the 30-second mark. Remove from the microwave, check to ensure it is heated through, and eat.

If your casserole serving needs more time, heat in 15-second increments until it reaches your desired temperature.

USING THE OVEN

If you’d like to heat your low-carb ground beef casserole more slowly, you can use your oven. It will give you a deliciously warm meal that’s been heated through.

Preheat your oven to 350˚F and place your leftover casserole into an oven-safe baking sheet. Heat for 10 minutes, stirring occasionally, then check for the desired temperature.

If your casserole isn’t heated through yet, continue to heat in the oven in four-minute increments until the desired level of temperature is reached.

Click on the links to see the items used in making this recipe. You can also find these products linked in the recipe below.

  • Meat Chopper – A meat chopper is an odd-looking tool that can make breaking apart ground meat or sausage a breeze. The tool isn’t very big and will easily fit in your kitchen utensil drawer. If you don’t have a meat chopper and are constantly aggravated by breaking meat apart, it’s time to get one!
  • Non-Stick Skillet – A good non-stick skillet is a must for any kitchen. For this particular recipe, it makes cooking and cleanup a breeze. If you don’t have a non-stick skillet or if yours is getting some age on it and isn’t working well, there’s no time like the present to get one!
  • 9×13″ Baking Dish – The “nine by thirteen” is a baking dish that is synonymous with tons of recipes, especially when it comes to casseroles.
