Keto Tex-Mex Ground Beef Casserole

Step 1
Preheat the oven to 350 degrees F (175 degrees C). Spray an 11×7-inch baking dish with cooking spray.

Step 2
Heat a large nonstick skillet over medium-high heat. Cook and stir ground beef in the hot skillet until browned and crumbly, 5 to 7 minutes. Stir in 1 1/2 teaspoons chili powder, 1 teaspoon onion powder, 1 teaspoon garlic powder, cumin, coriander, salt, and pepper until spiced are distributed evenly. Cook until fragrant, 4 to 5 minutes. Remove from heat.

Step 3
Whisk together eggs and cream in a bowl; add to meat mixture. Spread mixture into the prepared baking dish and pat down evenly.

Step 4
Wipe the skillet clean, add olive oil, and heat over medium heat. Add onion and cook until soft and translucent, about 2 minutes. Add remaining 1 teaspoon each chili powder, garlic powder, and onion powder. Season with salt and pepper. Stir in tomato paste and cook, stirring often, 2 to 3 minutes. Add cauliflower rice and continue cooking for 4 to 5 minutes. Remove from heat, stir in 1 cup Cheddar cheese, and spread on top of meat in the baking dish, smoothing with a spatula to flatten the top.

Step 5
Bake in the preheated oven for 25 to 30 minutes. Sprinkle remaining 1/2 cup Cheddar over the top and bake until cheese has melted, about 5 minutes. Remove from oven and allow to cool about 5 minutes. Serve warm.
