  • 4 tablespoons butter unsalted if possible
  • 3 tablespoons all-purpose flour or quinoa, almond or other gluten-free flour
  • 1 ½ cups milk
  • Sea salt and ground pepper to taste
  • 1/8 heaping teaspoon ground nutmeg or more to taste

  • Preheat the oven to 425 degrees F.
  • Place cauliflower florets on a microwave-safe plate and cover with wet paper towel.

  • Melt the butter in a small sauce pan over medium heat.
  • Add flour and whisk until it makes a bubbly paste.
  • Gradually add the milk and stir until the sauce becomes thick and creamy.
  • Remove from heat and add salt, pepper, nutmeg and half of the sharp cheese. (Do not add the parmesan yet.)
