Keto Tex-Mex Beef Casserole

To begin, preheat your oven to a high temperature of 350 degrees Fahrenheit (175 degrees Celsius). Next, take an 11x7-inch baking dish and spray it with a non-stick cooking spray to ensure easy removal.

Heat up a large, non-stick skillet over high heat and cook ground beef in the hot pan until it's browned and crumbly, taking about 5 to 7 minutes. Add a blend of spices including chili powder, onion powder, garlic powder, cumin, coriander, salt, and pepper to the skillet and stir until these flavors are evenly distributed throughout. Continue cooking for an additional 4 to 5 minutes, allowing the aromas to meld together.

In a separate bowl, whisk eggs and cream until well combined. Add this mixture to the cooked ground beef and stir until everything is fully incorporated.

Transfer the meat mixture into the prepared baking dish and press it down firmly to create an even layer.

Clean the skillet thoroughly, add a small amount of olive oil, and heat it over medium heat. Add sliced onions to the pan and cook until they're soft and translucent, taking about 2 minutes. Add a small amount of each remaining spice blend and season with salt and pepper to taste. Stir in tomato paste and cook, stirring frequently, for 2 to 3 minutes. Add cauliflower rice and continue cooking for an additional 4 to 5 minutes. Remove the skillet from heat.

Stir in one cup of Cheddar cheese and spread it evenly over the top of the meat mixture in the baking dish. Use a spatula to smooth out the cheese and create an even layer.

Place the baking dish in the preheated oven and bake for 25 to 30 minutes, or until the cheese has melted. Remove the dish from the oven and sprinkle the remaining 1/2 cup of Cheddar cheese over the top. Return the dish to the oven and continue baking until the cheese has melted, taking about 5 minutes. Remove the dish from the oven and allow it to cool for about 5 minutes before serving warm.
