Ingredients

Servings
  • 2 lbs fresh cauliflower florets 900 g
  • 1 tablespoon vegetable oil 15 ml
  • 4 tablespoons butter 60 g, plus extra for greasing
  • 4 tablespoons all-purpose flour 30 g
  • 1 ½ cups whole milk 360 ml
  • 1 cup half-and-half cream 240 ml or substitute with whole milk
  • 1 teaspoon salt 5 g
  • 1 teaspoon onion powder 5 g
  • 1 teaspoon mustard powder 5 g or 1 teaspoon prepared mustard (5 ml)
  • ½ cup cheddar cheese shredded (60 g)
  • ½ cup mozzarella cheese shredded (60 g)
  • 3 lices Provolone cheese torn (about 60 g)
  • ¼ cup Parmesan Cheese shredded (25 g)
  • Optional Topping Fresh parsley, chives chopped, for garnish (optional)

Instructions

  1. Preheat the Oven: Preheat your oven to 425°F (220°C).

Roast the Cauliflower:

  1. Place the cauliflower florets on a parchment-lined baking sheet. Gently coat with vegetable oil using a pastry brush.
  2. Bake for 15 minutes or until the florets develop golden-brown spots. Remove from the oven and set aside. Reduce the oven temperature to 375°F (190°C).

Make The Cheese Sauce

  1. Melt the butter in a large saucepan over medium heat. Add the flour and stir continually for about 3 minutes.
  2. Gradually stir the milk and cream, whisking to create a smooth sauce. Cook for about 5 minutes until thickened. NOTE: For low-carb keto variation, add 1/4 tsp xantham gum and stir until incorporated. Add additional xantham if needed until desired consistency is reached.
  3. Remove from heat and stir in the cheddar, mozzarella, provolone, salt, onion powder, and mustard powder.

Assemble the Dish

  1. Lightly butter a 13" x 9" (33 cm x 23 cm) baking dish. Gently stir the roasted cauliflower into the cheese sauce, ensuring all florets are coated. Pour the mixture into the prepared baking dish and sprinkle with grated parmesan.

Bake

  1. Bake at 375°F (190°C) for 20 minutes, until the top is golden. For a deeper color (and crispy, cheesy bits!), broil for 3–4 minutes. Watch closely. If using a panko or bread topping, add just before baking.

Cool and Garnish

  1. Let the dish cool for at least 5 minutes before serving. Sprinkle with parsley, diced onions, or chives, if desired.

Notes

  • Use a pastry brush when applying the oil to the cauliflower to ensure you get all the nooks and crannies.
  • For low-carb alternatives, replace the flour with 1/4 teaspoon of xanthan gum adding it to the milk mixture. For the topping, use crushed pork rinds.  
  • Pick cauliflower that is firm not soft or mushy. A large head of cauliflower will provide about 2 pounds of florets. 
  • Use a pastry brush when applying the oil to the cauliflower to ensure you get all the nooks and crannies.
  • When roasting the cauliflower flip each floret halfway through the cooking time for even fork-tender cauliflower.
  • Stir the cheese sauce often to avoid burning.
