Ingredients
  

  • 1.5 pounds (680 g) ground beef (80–90% lean works best)
  • 1 large head cauliflower (about 2 pounds), cut into small florets
  • 1 small onion, finely chopped
  • 3 cloves garlic, minced
  • 1 cup (240 ml) heavy cream
  • 4 ounces (115 g) cream cheese, softened and cubed
  • 2 cups (200 g) shredded cheese (cheddar, Monterey Jack, or a blend)
  • 2 tablespoons tomato paste
  • 1 teaspoon smoked paprika
  • 1 teaspoon dried oregano
  • 1/2 teaspoon chili powder (optional, for mild heat)
  • 2 tablespoons olive oil or butter
  • Salt and black pepper, to taste
  • Fresh parsley or chives, chopped, for garnish (optional)

Method
 

  1. Preheat and prep: Heat your oven to 375°F (190°C). Grease a 9x13-inch baking dish with a little oil or butter.
  2. Cook the cauliflower: Steam or microwave the florets until just tender, about 6–8 minutes. Drain well and blot dry with paper towels. Excess water will make the casserole runny.
  3. Brown the beef: Warm 1 tablespoon oil in a large skillet over medium-high heat. Add the ground beef and cook, breaking it up, until browned and no longer pink, 6–8 minutes. Drain excess fat if needed.
  4. Add aromatics: Push beef to one side. Add remaining oil, onion, and a pinch of salt. Sauté 3–4 minutes until softened. Stir in garlic for 30 seconds.
  5. Season and enrich: Stir in tomato paste, smoked paprika, oregano, and chili powder. Cook 1 minute to bloom the spices. Season with salt and pepper.
  6. Make the creamy sauce: Reduce heat to medium-low. Add heavy cream and cream cheese. Stir until smooth and slightly thickened, 2–3 minutes. Taste and adjust seasoning.
  7. Fold in cauliflower: Gently mix the drained cauliflower into the beef mixture until evenly coated with sauce.
  8. Assemble: Spread the mixture in the prepared baking dish. Top with shredded cheese, spreading it to the edges for an even golden crust.
  9. Bake: Bake for 18–22 minutes, until the casserole is bubbling and the cheese is melted and lightly browned.
  10. Finish and serve: Let it rest 5–10 minutes to set. Garnish with chopped parsley or chives. Scoop and serve.
