Description

This Cauliflower Au Gratin is a classic, tasty, and simple casserole dish. It is great for any holiday or just a dinner side where you want something special.

Ingredients

Units Scale
  • 1 whole cauliflower, cleaned and green leaves removed
  • 2 tablespoon butter
  • 3 tablespoon flour
  • 2 cups milk
  • 3 ounces (about 1.5 cups) Shredded Swiss cheese
  • 1/2 teaspoon salt
  • 1/4 teaspoon pepper
  • 1/4 teaspoon cayenne
  • 1/2 cup Italian Bread Crumbs

Instructions

  1. Preheat oven to 375° Fahrenheit
  2. Fill a large pot full of water and bring to a soft boil
  3. Add Cauliflower and cook for 15 minutes or until tender when you put a fork in it.
  4. Remove from hot water and as soon as cauliflower is cool enough to handle, cut florets into bite sized pieces. 
  5. In sauce pan, heat butter on medium heat until melted
  6. Add flour to butter and mix. It will appear like a thick paste. 
  7. Slowly add milk and stir well. The goal is to integrate the butter, flour mixture with the milk. Turn heat up to medium-high.
  8. Heat and stir until sauce thickens. Continue stirring until sauce starts to thicken.
  9. Once thickened add half of the cheese and mix. Remove from heat and continue to mix for a minute to ensure dairy doesn’t scald.
  10. Add salt, pepper, and cayenne to sauce.
  11. In casserole dish, add ⅓ sauce, cauliflower, and then the rest of the sauce, ensuring to cover all florets.
  12. Spread breadcrumbs evenly over top.
  13. Spread remaining cheese evenly over top.
  14. Bake in oven for 40 minutes.
  15. Remove from Oven and Serve.

Notes

  • Remove the leaves before you boil the cauliflower. Your dog might like them as a treat. 🙂
  • Use quality bread crumbs for the best result
  • Layer your sauce in the casserole dish. Mornay sauce, the cauliflower, more mornay sauce.
  • Bake until heated and cheese on top looks nice and melted. About 25 minutes.
