Ingredients

Instructions

  • Remove the leaves and stem from the head of cauliflower and then trim the cauliflower into bite-size florettes.
  • Add them to a large pot of boiling salted water and cook for 5 minutes.
  • Drain the cooked cauliflower very well before transferring to a baking dish.
  • Pour in the mornay sauce and mix until completely coated and mixed in.
  • Evenly sprinkle the breadcrumbs over top, covering the cheesy cauliflower.
  • Bake at 400° for 20 to 25 minutes or until browned on top and especially around the outside of the inside of the baking dish.
  • Add an optional garnish of parsley and serve.

Notes

Chef Notes:
  • How to Reheat: Cover with foil or a oven safe lid and cook at 350° for 15-20 minutes or until hot.
  • Make-Ahead: You can make this recipe up to 1 day ahead. Simply reheat 30 minutes before serving.
  • How to Store: Cover and place in the refrigerator for up to 4 days.
  • How to Freeze: Cover and place in the freezer for up 2 months. Thaw 1 day in the refrigerator before reheating.
  • It is very important that the cauliflower be drained completely before mixing with the sauce or else it will become runny.
