Many of you know that if a dish has too many ingredients, I won’t go near it. But I still like it made fresh – not with a lot of processed food. Since going on the Keto diet, I’ve had to make some adjustments and make a few dishes that are more complicated to get rich flavors and textures. Not this time though – I think we’ve found a winner in this Simple Keto Cheeseburger Casserole that is something I can whip up quickly any night with ingredients we always have on hand.

It looks a little something like this…

Browning the beef is the first step. And also starts your kitchen smelling amazing! You could use turkey or sausage for a different twist. But good old ground beef will do just fine.

The finished product will not last long in the bowl!

All that texture in there is cauliflower! I’ve been craving potatoes and this is the closest this Keto girl can come to that texture and flavor. It did not disappoint. It’s also nice and saucy, so it’s very filling. I used mozzarella, but you could totally class it up with your favorite cheeses.

It made enough for lunch leftovers which is awesome! Here’s the recipe – I did wing it a bit which I tend to do, but this is about what I added.

Simple Keto Cheeseburger Casserole


  • 1 lb ground beef
  • 2 tbs Kerrigold salted butter
  • 1/2 c almond flour (we use this one)
  • 1 tbs dijon mustard
  • 7 oz package mozzarella cheese
  • 2 c heavy whipping cream
  • 4 c cauliflower rice (or nibblets), cooked
  • 1 tsp garlic powder
  • 1 tsp salt
  • 1/2 chopped onion


Preheat oven to 350 degrees. Sauté the onion over medium heat until soft. Brown the ground beef and remove from pan – retain the grease and add 1 tbs butter until melted. Add back in the onion and the salt and garlic powder and stir. Add almond flower and heavy whipping cream. Stir over low heat until the sauce begins to thicken.

In a 13×9 baking dish, melt the remaining 1 tbs butter on the bottom (more if you want cuz butter!). Add the cooked cauliflower and spread evenly. Pour half the sauce over the cauliflower and top with 1/2 the bag of cheese (I use a fork to spread it around a bit). Add the ground beef and remaining sauce on top (again fork, spread). Sprinkle with the remaining cheese.

Bake for 25 minutes with foil over top. Remove the foil and bake another 10 minutes. Let set for 10 minutes before serving.

Next time I might sautee some mushrooms with the onion. Maybe even some green peppers. I think you could really do anything with this. It’s so flavorful but not heavy.

Pin it for later!

    You also didn’t say anything in the recipe about when to put in the mustard I’m guessing during making the sauce ??

    What are the macros on this dish? Counting fat/protein/carbs on keto important.
