Description

This creamy cauliflower au gratin recipe with crispy bacon, thyme, and homemade cheese sauce is an easy, veggie-packed holiday side.


Ingredients

Scale
  • 4 strips of bacon, diced
  • 2 head of cauliflower, cut into florets
  • 2 tablespoons unsalted butter
  • 2 1/2 tablespoon flour
  • 1 1/2 cups 2% milk
  • 1 1/4 cup + 2 tablespoons Tillamook Sharp White Cheddar Cheese, shredded
  • 1 tablespoon of fresh thyme (plus more for garnish)
  • salt & pepper to taste

Instructions

  1. Preheat oven to 400 degrees F.
  2. Bring a small skillet to medium high heat. Add the bacon and saute until crispy, about 3-4 minutes.
  3. Remove bacon from the skillet and place on a paper towel lined plate to let the grease drain out. Set aside.
  4. Bring a large pot of water to a boil.
  5. Add the cauliflower florets to the pot and cook for 4-5 minutes, until the cauliflower is just tender.
  6. Pour cooked cauliflower into a colander and drain all the liquid. (Be sure all liquid is gone, so you don’t end up with a watery casserole)
  7. Pour drained cauliflower into a 13×9 inch baking dish.
  8. In the meantime, heat a medium saucepan to medium high heat.
  9. Add butter to sauce pan and melt. Then add flour to pan. Whisk the flour and butter together, continue to do so for at least 3 minutes.
  10. Then slowly pour in the milk, whisking the entire time. Bring milk mixture to a boil. Reduce to simmer. Let the milk mixture simmer for about 6-8 minutes to thicken up. Whisking occasionally.
  11. Remove the saucepan from the heat. Add in the 1 1/4 cup shredded cheese, fresh thyme, salt, and pepper.
  12. Whisk until cheese is melted and mixture is smooth.
  13. Pour cheese sauce over the cauliflower.
  14. Using a spoon, gently mix the cheese sauce and cauliflower together.
  15. Sprinkle the top of the cauliflower with bacon, additional fresh thyme, and 2 tablespoons of shredded cheese.
  16. Place baking dish in the oven and bake for 20 minutes until slightly browned.
  17. Remove from oven and serve.
