Ingredients

  • 1 large head cauliflower cut into small pieces (about the size of the thumb), equal to 6-7 cups
  • 1 tbsp butter
  • 1 tbsp flour see notes
  • ¾ cup milk see notes
  • ½ tsp garlic powder
  • 1 tsp fine sea salt to taste
  • black pepper to taste
  • 1 ½ cups shredded cheddar cheese off the block
  • ½ cup shredded gruyere cheese off the block

Breadcrumb Topping

  • cup panko breadcrumbs
  • 1 tbsp unsalted butter melted
  • ½ tsp fine sea salt
  • minced parsley for garnish

Instructions

  • Preheat oven to 375ºF and grease 9x9 casserole dish with butter or oil. Set aside.
  • Boil Cauliflower: Bring a large pot of water to boil. Place cauliflower florets in pot (making sure water is covering cauliflower) and cook for 4 minutes. Cauliflower should be tender but not too soft. Drain and pat dry, then transfer to prepared dish.
  • Make cheese sauce: In a medium saucepan over medium-high heat, add butter and flour. Stir constantly until well combined. Slowly add in milk, whisking until combined. Reduce heat to medium and allow mixture to thicken, stirring occasionally, about 3-5 minutes. Add garlic, pepper, and salt. Add cheese and whisk until cheese is melted and sauce is smooth. Pour over cauliflower in dish.
  • Make breadcrumbs: In a small bowl, mix together breadcrumbs, butter, and salt. Scatter into one even layer over cauliflower.
  • Bake: Bake for 20-25 minutes, or until breadcrumbs are golden brown. Let dish stand for 10 minutes before serving.

Notes

MAKE AHEAD - prepare the cauliflower and the cream sauce up to 2 days in advance and store separately in the fridge. Combine and bake as instructed on the day you are going to serve.
STORAGE - leftover cauliflower mac can be stored tightly covered with plastic wrap or in an airtight container in the fridge for 4 days. We do not recommend freezing.
REHEAT - cover with aluminum foil and reheat in a low oven (300 degrees F) for 15-20 minutes, until warm. OR, reheat individuals portions in the microwave.
