  • Preheat oven to 350 degrees F.
  • Cut the cauliflower into florets and rinse under cold water. Add them to double boiler with water in the bottom along with the lid and steam them until soft; approximately 3-4 minutes after the water comes to a boil. Drain the water and add the cauliflower to the pot.
  • While the cauliflower is steaming, make the cheese sauce. Melt 3 tablespoons of butter over medium heat in a small saucepan and whisk in the flour to form a roux.
  • Add milk and cheese, reduce heat to a simmer and stir until sauce thickens.
  • Add the cheese sauce to the cauliflower and mix well; then add to an oven safe baking dish.
  • Melt the remaining 2 tablespoons of butter and combine with the breadcrumbs. Sprinkle the crumbs on top of the cauliflower and bake 30 minutes until hot and bubbly.
