Creamy Ground Beef Cauliflower Casserole Recipe (Recipe of the Year)

It goes without saying that I make and create a lot of new recipes. Some I'd like to forget I made, and some I cannot wait to make again. This creamy ground beef and riced cauliflower casserole recipe is one that I cannot wait to make again. It was one of the best recipes I made in 2023. I want to make it again, but it's not far to the 2024 recipes because it probably would win again! Yes, it's that good. 

The keto-friendly casserole is super simple to make, too. You start by chopping cauliflower into very small pieces (riced) and microwaving it for 5 minutes to soften. Ground beef and onion are cooked in a little butter, then the flavorful ingredients join in. A little cream cheese, some heavy whipping cream, beef broth, tomato paste and garlic powder are stirred in, then the riced cauliflower. The mixture is cooked until most of the liquid evaporates and thickens up. Top with mozzarella and cheddar and let it melt right there on the stovetop. No oven needed. Amazing flavors, textures and a creamy consistency!

This is a complete low-carb dinner, but I did toss together a spring mix salad with lemon vinaigrette to enjoy with it. You could also serve it with a steamed or roasted vegetable. This is one cheesy casserole recipe you really need to try.

Recipe Notes

  • You could pop the skillet under the broiler (if it is ovenproof) if you want a browner top. But we loved the cheese strings when we spooned the casserole onto our plates. 
  • Shred your own cheese and it melts better than those bags of pre-shredded cheese.
  • If you don't want to chop fresh cauliflower, you could use a bag of frozen riced cauliflower cooked according to package directions.

Here's how to make it: 

  1. Put the riced cauliflower and 1/2 cup of water into a microwave-safe bowl and cover with plastic wrap. Microwave for 5 minutes. Drain and set aside.
  2. Melt the butter in a skillet (I used a cast iron skillet). Add the ground beef and onion and cook until meat is cooked through, about 5 minutes.
  3. Add the cream cheese, heavy whipping cream, beef broth, tomato paste and garlic powder. Generously season with salt and pepper. Stir until cream cheese melts.
  4. Add the cauliflower and stir to coat. Add chopped parsley or parsley flakes, if desired. Bring to a gentle simmer and cook, stirring occasionally, until most of the liquid has evaporated and it thickens up, about 8 to 10 minutes.
  5. Top with the cheddar and mozzarella. Cook, without stirring, until cheese melts.
