Ingredients

Scale

Main Ingredients

  • 10 ounces Frozen Cauliflower Rice
  • 23 Tablespoons 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
  • Fresh Cilantro
  • Sliced Jalapeno
  • Salsa or Hot Sauce

Instructions

  1. Preheat Oven: Preheat your oven to 350ºF (177ºC) to prepare for baking the casserole later.
  2. Sauté Cauliflower Rice: Heat 2-3 tablespoons of oil in a pan over medium-high heat. Add the frozen cauliflower rice and cook until lightly browned. This step gives the cauliflower a tender, slightly crispy texture. Once done, transfer the cauliflower evenly into a greased 2-quart casserole dish.
  3. Cook Ground Beef and Veggies: In the same or another pan, brown 2 pounds of ground beef over medium-high heat. Add the chopped red bell pepper and white onion and cook until softened. Drain any excess fat if needed to keep the dish lighter and prevent greasiness.
  4. Season the Meat: Stir in 4 tablespoons of taco seasoning, 1 tablespoon of tomato paste, and 1/2 cup water. Continue cooking until the liquid is mostly absorbed and the mixture is well combined and flavorful. Spread this meat mixture evenly over the layer of cauliflower rice in the casserole dish.
  5. Add Cheese & Bake: Sprinkle 3 cups of shredded Colby Jack cheese evenly on top of the meat layer. Place the casserole in the preheated oven and bake for 10-15 minutes, or until the cheese is melted and bubbly.
  6. Top and Serve: Remove from the oven and spread 1 cup of sour cream over the top. Optionally, add extra shredded cheese and your favorite toppings such as chopped lettuce, tomato, black olives, avocado or guacamole, cilantro, sliced jalapenos, and salsa or hot sauce for added flavor and texture.

Notes

  • Make sure to drain excess fat from the cooked ground beef for a leaner casserole.
  • You can customize the toppings based on your preference or dietary needs.
  • Use freshly grated cheese for better melting and flavor.
  • If frozen cauliflower rice is not available, you can finely chop fresh cauliflower as a substitute.
  • This casserole can be prepared ahead and refrigerated before baking to save time.
