Instructions
- Preheat Oven: Preheat your oven to 375°F (190°C) to ensure it’s ready for baking the casserole later.
- Cook Ground Beef: In a skillet over medium heat, cook 1 lb of ground beef until it is fully browned. Once cooked, drain any excess grease from the pan to keep the dish from becoming too oily.
- Sauté Vegetables: Add the chopped onion, diced bell pepper, and minced garlic to the skillet with the beef. Cook these together until the vegetables become soft and fragrant, which usually takes about 5 minutes.
- Add Spices: Stir in the taco seasoning packet, ground cumin, chili powder, paprika, salt, and black pepper to the beef and vegetable mixture. Mix well to evenly coat all ingredients with the spices.
- Incorporate Cauliflower Rice and Tomatoes: Add the cauliflower rice and the drained can of Rotel diced tomatoes with green chilies to the skillet. Heat the mixture through, stirring occasionally, for about 3-4 minutes.
- Melt in Cream Cheese: If using, add the cream cheese to the skillet and stir until it melts completely and melds into the mixture, creating a creamy texture.
- Transfer to Baking Dish: Lightly grease a 9×13 inch baking dish. Pour the beef and vegetable mixture into the dish and spread it out evenly.
- Top with Shredded Cheese: Sprinkle the 2 cups of shredded cheddar or Mexican blend cheese evenly over the top of the casserole mixture.
- Bake: Place the baking dish in the preheated oven and bake for 20 to 25 minutes, or until the cheese on top is melted, bubbly, and slightly golden.
- Rest and Serve: Remove the casserole from the oven and allow it to rest for 5 to 10 minutes to set. Add your preferred optional toppings such as sour cream, cilantro, green onions, or avocado. Serve warm and enjoy!
