Ingredients

Scale
  • 1 large head cauliflower, cut into bite-sized florets (about 4 cups)
  • 1 cup shredded sharp cheddar cheese
  • 1/2 cup shredded mozzarella cheese
  • 1/4 cup grated Parmesan cheese (for topping)
  • 4 ounces cream cheese, softened
  • 1/2 cup heavy cream (full-fat; can substitute coconut cream for dairy-free)
  • 2 tablespoons unsalted butter
  • 1/2 teaspoon garlic powder
  • 1/2 teaspoon onion powder
  • 1 teaspoon Dijon mustard
  • Salt and pepper to taste
  • Optional: pinch of smoked paprika or cayenne pepper

Instructions

  1. Preheat your oven to 375°F (190°C).
  2. Cut the cauliflower into bite-sized florets, aiming for uniform pieces.
  3. Steam the cauliflower for 8 minutes or boil for 5-6 minutes until just fork-tender but still firm.
  4. Drain well and pat dry thoroughly to remove excess moisture.
  5. In a medium saucepan, melt butter over medium heat. Whisk in softened cream cheese until smooth.
  6. Add heavy cream, garlic powder, onion powder, and Dijon mustard. Stir continuously until smooth and slightly thickened, about 3-4 minutes.
  7. Remove from heat and stir in shredded cheddar and mozzarella until melted and creamy. Season with salt and pepper to taste.
  8. Place the drained cauliflower in a mixing bowl and pour the cheese sauce over it. Gently mix to coat evenly.
  9. Transfer the mixture to a 9×9-inch baking dish. Sprinkle grated Parmesan and a little extra shredded cheddar on top.
  10. Bake uncovered for 15-20 minutes until the top is bubbly and golden brown. Tent with foil if browning too quickly.
  11. Let rest for 5 minutes before serving.
  12. Optional: For an extra crispy top, broil for 1-2 minutes at the end, watching carefully to avoid burning.

Notes

Do not overcook cauliflower to avoid mushiness. Dry cauliflower thoroughly after cooking to prevent watery sauce. Use moderate heat and whisk constantly when making cheese sauce to avoid graininess. Parmesan topping is essential for a crispy, flavorful crust. Broil briefly at the end for extra crispiness but watch carefully to prevent burning.
