Ingredients

Scale
  • 1 medium head cauliflower, riced (about 4 cups)
  • 8 slices bacon, cooked and crumbled
  • 1 pound ground beef (80/20 fat ratio preferred)
  • 4 ounces cream cheese, softened
  • 1 ½ cups shredded cheddar cheese (about 150 g)
  • ½ cup heavy cream (120 ml)
  • 1 tablespoon Dijon mustard
  • 1 teaspoon garlic powder
  • 1 teaspoon onion powder
  • Salt and pepper to taste
  • 1 large egg, beaten
  • ¼ cup grated Parmesan cheese (about 25 g)
  • Optional toppings: sliced pickles, diced tomatoes, chopped green onions

Instructions

  1. Preheat your oven to 400°F (200°C).
  2. Rice the cauliflower by cutting it into florets and pulsing in a food processor until fine and rice-like (about 4 cups). If using frozen, thaw completely and squeeze out excess moisture with a kitchen towel.
  3. Transfer the riced cauliflower to a microwave-safe bowl and microwave uncovered for 5-6 minutes, stirring halfway. Let cool slightly.
  4. In a mixing bowl, combine the cooked cauliflower rice, beaten egg, Parmesan cheese, salt, and pepper. Mix well.
  5. Press the cauliflower mixture firmly into a greased 9×13-inch baking dish to form a thin crust layer. Bake for 15-20 minutes until golden and set.
  6. Cook the bacon in a large skillet over medium heat until crispy (8-10 minutes). Drain on paper towels and crumble. Reserve 1 tablespoon bacon fat in the skillet.
  7. Add ground beef to the skillet with bacon fat and cook over medium-high heat until browned and fully cooked (7-8 minutes), breaking it up with a spoon. Drain excess fat if needed.
  8. Reduce heat to low and stir in cream cheese, heavy cream, Dijon mustard, garlic powder, onion powder, salt, and pepper. Cook, stirring occasionally, until smooth and creamy (3-4 minutes). Stir in half the shredded cheddar and all the crumbled bacon.
  9. Pour the creamy beef mixture over the baked cauliflower crust and spread evenly. Top with remaining shredded cheddar cheese.
  10. Bake the casserole for another 10-15 minutes until the cheese is melted and bubbly with golden spots.
  11. Let the casserole rest for 5 minutes before slicing. Garnish with optional toppings like sliced pickles or chopped green onions.

Notes

Drain cauliflower rice thoroughly to avoid soggy crust. Press crust firmly before baking. Use sharp cheddar and fresh Parmesan for best flavor and texture. Let casserole rest before slicing for cleaner cuts. Can be assembled ahead and baked later with slightly longer baking time. Freezer-friendly for up to 2 months.
