  • 3 cups steamed cauliflower florets
  • 4 tablespoon butter
  • cup all purpose flour
  • 2 cups light cream or whole milk
  • ½ teaspoon each tarragon onion powder, garlic powder, white pepper & salt
  • 2 tablespoon Dijon mustard
  • 2 ½ cups shredded Italian blend cheese
  • Topping:
  • 1 cup crushed croutons or buttery crackers
  • 1 tablespoon melted butter


  • Preheat the oven to 350°F. Spray a 2 quart casserole dish with cooking spray. Set aside. Steam the cauliflower florets then roughly chop them into bite size pieces. Set aside to cool slightly while you prepare the sauce.
  • On the stove top over medium high heat, melt 4 tablespoon of butter in a small saucepan. Add ⅓ cup of flour. Whisk together until the butter and flour combine to form a roux.
  • Whisk all of the seasonings and the Dijon mustard into the light cream.
  • Lower the heat to medium. Slowly whisk the cream mixture into the roux, whisking continually. After adding all of the cream continue to whisk until it begins to bubble.
  • Lower the heat and allow it to gently simmer for 3-4 minutes.
  • Add 1 ½ cups of shredded cheese to the sauce, then remove the saucepan from the heat, stirring until the cheese has completely melted.
  • Divide the remaining cheese into three equal parts.
  • To assemble, ladle cheese sauce onto the bottom of the baking dish, next cauliflower then shredded cheese. Repeat ending with shredded cheese.
  • Sprinkle the buttered crumbs on top.
  • Bake for 30-35 minutes until golden and bubbly.


For the topping, I used Ranch flavored croutons for the crunchy topping. You could use your choice of seasoned breadcrumbs or buttery crackers, if desired.
