Ingredients
  

Roasted Cauliflower
  • 1 large head cauliflower, cut into small bite-sized florets
  • 2 tbsp olive oil
  • Salt and black pepper
Three-Cheese Sauce
  • 1 cup heavy cream
  • 1 ounces cream cheese, cubed
  • 1 1/2 cup sharp cheddar cheese, freshly shredded
  • 1/2 cup Monterey Jack cheese, freshly shredded
  • 1/4 cup Parmesan cheese, freshly grated
  • 1/2 teaspoon garlic powder
  • 1/2 teaspoon onion powder
  • 1/4 teaspoon smoked paprika
  • 1/4 teaspoon Dijon mustard
  • Pinch of cayenne pepper (optional)
  • Salt and black pepper to taste
Crispy Topping
  • 1/4 cup Parmesan cheese, grated
  • 2 tbsp melted butter
  • 1/4 teaspoon garlic powder
Optional Additions
  • 4 slices crispy bacon, crumbled
  • Fresh chives or parsley, chopped
  • Hot sauce

Method
 

  1. Preheat oven to 425°F. Spread cauliflower florets on a parchment-lined baking sheet. Drizzle with olive oil, season with salt and pepper. Roast for 18-20 minutes, flipping halfway, until golden and tender.
  2. While cauliflower roasts, heat heavy cream in a large pot over medium-low heat. Add cream cheese cubes and whisk until melted and smooth.
  3. Reduce heat to low. Add cheddar and Monterey Jack one handful at a time, stirring until melted. Stir in garlic powder, onion powder, smoked paprika, Dijon mustard, and cayenne. Season with salt and pepper.
  4.  Add roasted cauliflower to the cheese sauce and gently fold until every piece is coated. Transfer to an oven-safe baking dish.
  5. Mix grated Parmesan, melted butter, and garlic powder in a small bowl. Sprinkle over the top of the cauliflower mac and cheese.
  6. Broil on high for 2-3 minutes until topping is golden and crispy. Top with bacon, chives, or hot sauce if desired. Serve immediately.
