Instructions
- Preheat the Oven
Preheat your oven to 375°F (190°C). Grease a 9×9-inch casserole dish with cooking spray or butter. - Cook the Ground Beef
In a large skillet, heat a tablespoon of oil over medium-high heat. Add the ground beef and cook, breaking it up with a spoon, until browned and cooked through (about 6–8 minutes). Drain excess fat if necessary. - Sauté the Vegetables
Add the diced onion, garlic, and bell pepper to the skillet with the beef. Cook for 4–5 minutes, until the vegetables soften. - Season the Mixture
Stir in the paprika, oregano, cumin, salt, and pepper. Continue cooking for another 2 minutes to allow the spices to bloom. - Add the Cauliflower Rice
Add the cauliflower rice to the skillet, stirring to combine with the beef and vegetables. Cook for 3–5 minutes, until the cauliflower rice is heated through and tender. - Assemble the Casserole
Transfer the beef and cauliflower rice mixture into the prepared casserole dish. Spread it evenly, then sprinkle the shredded cheddar cheese on top. - Bake
Place the casserole in the preheated oven and bake for 15–20 minutes, or until the cheese is melted and bubbly. - Garnish and Serve
Remove the casserole from the oven and let it cool for a few minutes. Garnish with freshly chopped parsley, if desired. Serve warm.

- Cheese: Feel free to substitute cheddar cheese with mozzarella, Monterey Jack, or a cheese blend if you prefer.
- Ground Beef: For a leaner option, you can substitute ground turkey or chicken instead of beef.
