Instructions

  1. Preheat oven to 400°F.

Roast Cauliflower

  1. Rinse cauliflower and break into bite-sized florets. Toss with olive oil and salt and pepper to taste.
  2. Place on a baking sheet and roast 15-20 minutes or until tender.

Make Sauce

  1. While cauliflower is roasting, melt butter (and garlic if using) in a saucepan until fragrant, about 30 seconds. Whisk in flour until smooth and let cook for 1 minute. Add milk a little at a time while whisking until smooth.
  2. Cook over medium heat until thick and bubbly. Stir in cream cheese, salt, black pepper, and mustard powder until smooth. Add in ¾ cup cheddar cheese and swiss cheese. Whisk until smooth.

Bake

  1. Toss cheese mixture with roasted cauliflower and place in a 2 qt casserole dish. Top with remaining cheese and bake 20-25 minutes or until heated through.
  2. Broil 1-2 minutes or until browned.

Notes

  • Roasting the cauliflower keeps the sauce from getting watery. If you steam or boil (or use frozen) be sure to drain very well.
  • Broccoli can be added to the cauliflower if desired.
  • The sauce is very rich, ensure your cauliflower head is at least 7-8 cups.
  • Remove the sauce from the heat before stirring in the cheese. If the cheese overheats or boils it can separate. 
  • The cheese on top can be replaced with buttery bread crumbs. Combine 1/3 cup breadcrumbs with 1 tablespoon melted butter and sprinkle over top before baking.
  • Leftovers can be stored in an airtight container in the refrigerator for up to 4 days.
