I swear we just made the BEST Keto Ground Beef Casserole with cauliflower mash, cheesy topping that was to die for! It’s loaded with flavor and wonderful comfort food that’s keto friendly!

If you are staring at a package of ground beef and don’t know what to make for dinner, this one is super simple! It only takes about 15 minutes to prep it and get it in the oven too! It will take longer if you make the cauliflower mash yourself but you can buy cauliflower mash already premade in the freezer section of your local grocery store. Just pop that bad boy in the microwave for about 5 minutes and you have instant cauliflower mash!

This recipe is pretty hardy and filling too! This recipe makes 6 to 7 servings. I always like to make extra servings like this so my daughter and I can take leftovers with us the next day for lunch.

Keto Ground Beef Casserole Ingredients

2 lbs ground beef
1/2 onion, diced
1 14.5 oz can Green beans, drained
1 cup Beef Broth
1 tsp Xanthan Gum
1 tablespoon chili powder
2 tsp cumin
2 tsp oregano
2 tsp onion powder
1 tablespoon horseradish
2 tsp salt
2 tsp pepper
20 oz Cauliflower Mash (or prep 1 small head cauliflower)
2 tsp smoked paprika
3/4 cup cheddar cheese

Keto Ground Beef Casserole Instructions

Preheat the oven to 350 degrees.
In a large cast iron skillet, start by sauteing the onions until translucent.
Add the ground beef and cook it until it’s browned.
Drain the fat from the ground beef.
Add the seasonings (chili powder, oregano, onion powder, salt, and pepper) and horseradish sauce to the cooked ground beef and stir until it’s well combined.
Spread all the ground beef to the sides of the pan to make a hole in the center of the pan.
Pour the cup of beef broth in that hole in the pan and sprinkle the Xanthan gum over the liquid. Whisk the liquid until it’s fully dissolved the Xanthan gum.
Stir the liquid and the ground beef together. It will seem a bit watery but the sauce will thicken as it bakes in the oven.
Add the green beans and mix.
Spread the cauliflower mash over the top of the ground beef casserole in the skillet.
Sprinkle the cauliflower mash with smoked paprika.
Sprinkle the top of the cauliflower with the shredded cheddar cheese.
Bake this ground beef casserole at 350 degrees for 25 to 30 minutes.
Allow this casserole to cool for about 5 to 10 minutes before serving.
Enjoy!

If you don’t own an enameled cast iron frying pan like this, I highly suggest you invest in one. I love coated cast iron pans! They are easy to clean too!
