Introduction
This Low Carb Taco Casserole is a delicious and hearty dish perfect for taco lovers seeking a healthier twist. Featuring cauliflower rice and flavorful seasoned beef, it’s an easy, crowd-pleasing meal that comes together quickly and bakes to cheesy perfection.

Ingredients
- 10 ounces frozen cauliflower rice
- 2-3 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, cilantro, sliced jalapeno, salsa or hot sauce
Instructions
- Step 1: Preheat your oven to 350ºF (175ºC).
- Step 2: Heat oil in a pan over medium-high heat and pan-fry the frozen cauliflower rice until browned. Transfer it to a greased 2-quart casserole dish and spread evenly.
- Step 3: In the same pan, brown the ground beef with the chopped red bell pepper and onion over medium-high heat. Drain excess fat if needed. Stir in the taco seasoning, tomato paste, and water, cooking until the liquid is absorbed. Spread this mixture evenly over the cauliflower rice in the casserole dish.
- Step 4: Sprinkle the shredded cheese over the beef layer and bake the casserole for 10 to 15 minutes, until the cheese is melted and bubbly.
- Step 5: Remove from oven and spread sour cream on top. Add extra shredded cheese if desired and garnish with your favorite toppings such as lettuce, tomato, olives, avocado, cilantro, jalapenos, and salsa or hot sauce.
Tips & Variations
- For a spicier kick, add diced jalapenos into the beef mixture while cooking.
- Swap ground beef for ground turkey or chicken for a leaner option.
- Use a mix of cheeses like cheddar and Monterey Jack for extra flavor.
- To keep it dairy-free, omit cheese and sour cream and try avocado slices or dairy-free yogurt instead.
Storage
Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat gently in the microwave or oven until warmed through. Adding fresh toppings after reheating keeps the dish bright and tasty.
