Instructions

Cook the Cauliflower Rice
Heat 1 tablespoon of oil in a large skillet over medium heat. Add the frozen cauliflower rice and cook for about 5–7 minutes, stirring occasionally, until heated through and slightly browned. Set aside. -
Cook the Ground Beef
In the same skillet, add the remaining oil and ground beef. Cook over medium heat, breaking it apart with a spoon, until browned and cooked through (about 6–8 minutes). -
Add the Vegetables
Add the chopped red bell pepper and onion to the skillet with the beef. Cook for an additional 3–5 minutes until the vegetables are softened. -
Add Taco Seasoning and Tomato Paste
Stir in the taco seasoning and tomato paste, mixing well. Add the water and simmer for 2–3 minutes to combine the flavors. Remove from heat. -
Assemble the Casserole
Preheat your oven to 375°F (190°C). In a greased 9×13-inch baking dish, layer the cauliflower rice at the bottom. Top with the seasoned beef and vegetable mixture, spreading it out evenly. -
Add the Cheese
Sprinkle the shredded cheese evenly over the top of the casserole. -
Bake
Place the casserole in the preheated oven and bake for 15–20 minutes, or until the cheese is melted and bubbly. -
Finish and Serve
Remove from the oven and let the casserole cool slightly before serving. Add a dollop of sour cream on top of each serving for extra creaminess.
