Ingredients

Scale
  • 1 large head cauliflower, cut into bite-sized florets
  • 1 cup sharp cheddar cheese, shredded
  • 1/2 cup mozzarella cheese, shredded
  • 4 oz cream cheese, softened
  • 1/2 cup heavy cream (full-fat)
  • 2 tablespoons unsalted butter
  • 1 teaspoon garlic powder
  • 1 teaspoon Dijon mustard
  • Salt and black pepper, to taste
  • Optional: pinch of smoked paprika or cayenne pepper

Instructions

  1. Preheat the oven to 425°F (220°C) and line a baking sheet with parchment paper or foil.
  2. Wash and cut the cauliflower into bite-sized florets, ensuring even size for roasting.
  3. Toss the florets with 1 tablespoon melted butter, salt, and black pepper. Spread in a single layer on the baking sheet.
  4. Roast cauliflower for 20-25 minutes until tender and lightly browned at the edges.
  5. While roasting, melt the remaining 1 tablespoon butter in a medium saucepan over medium heat.
  6. Add softened cream cheese and stir until mostly melted and smooth.
  7. Slowly whisk in heavy cream, garlic powder, and Dijon mustard. Cook for 2-3 minutes until sauce thickens slightly.
  8. Remove from heat and stir in shredded cheddar and mozzarella until melted and creamy. Season with salt, pepper, and optional smoked paprika or cayenne.
  9. Transfer roasted cauliflower to a large mixing bowl and pour cheese sauce over it. Gently fold to coat evenly.
  10. Serve immediately for a softer texture or transfer to a baking dish and broil for 3-5 minutes for a golden cheese crust.
  11. Let rest for 2-3 minutes before serving to thicken the sauce.

Notes

Do not overcrowd the baking sheet to avoid steaming the cauliflower. Use full-fat dairy for best sauce texture. Freshly shred cheese for smooth melting. Roast cauliflower until just tender to avoid mushiness. Slowly melt cream cheese to prevent lumps. Broil carefully to avoid burning the cheese crust. If sauce is too thick, add a splash of cream or broth. Pat cauliflower dry before roasting to reduce wateriness.
