Scale
Main Ingredients
- 10 ounces Frozen Cauliflower Rice
- 2–3 Tablespoons Oil (such as olive or avocado oil)
- 2 Lbs Ground Beef
- 1 Small Red Bell Pepper – seeded and chopped
- 1 Small White Onion – chopped
- 4 Tablespoons Taco Seasoning
- 1 Tablespoon Tomato Paste
- 1/2 Cup Water
- 3 Cups Shredded Colby/Jack Cheese
- 1 Cup Sour Cream
Toppings
- Chopped Lettuce
- Chopped Tomato
- Sliced Black Olives
- Avocado or Guacamole
- Cilantro
- Sliced Jalapeno
- Salsa or Hot Sauce
Instructions
- Preheat Oven: Preheat your oven to 350ºF (175ºC) to prepare for baking the casserole later.
- Cook Cauliflower Rice: Heat 2-3 tablespoons of oil in a pan over medium-high heat. Add the frozen cauliflower rice and cook, stirring occasionally, until it is browned and slightly crisp. Then, transfer it evenly into a greased 2-quart casserole dish.
- Brown Ground Beef Mixture: In the same pan, cook the ground beef along with the chopped red bell pepper and onion over medium-high heat until the beef is fully browned. Drain any excess fat, if necessary. Add the taco seasoning, tomato paste, and 1/2 cup water to the beef mixture. Stir well and continue cooking until the liquid is mostly absorbed.
- Assemble Casserole: Spread the seasoned ground beef mixture evenly over the layer of cauliflower rice in the casserole dish. Sprinkle the shredded Colby/Jack cheese over the top.
- Bake: Place the casserole in the preheated oven and bake for 10 to 15 minutes, or until the cheese has melted and bubbly.
- Add Sour Cream and Toppings: Remove the casserole from the oven. Spread the sour cream evenly over the top layer. Sprinkle with additional shredded cheese if desired, then add your favorite toppings such as chopped lettuce, tomatoes, sliced black olives, avocado or guacamole, cilantro, sliced jalapenos, and salsa or hot sauce.
