Ingredients Method Notes

Ingredients
  

  • 1 large cauliflower head, cut into florets
  • 1 cup Monterey Jack Cheese, shredded
  • 1 cup sharp cheddar cheese, shredded
  • 8 slices bacon, cooked and crumbled, divided
  • 3/4 cup sour cream
  • 1/4 cup cream cheese, room temperature
  • 2 tsp brown mustard
  • 1 tbsp fresh parsley, finely chopped
  • 2 tsp fresh chives, finely chopped
  • 1/2 tsp pink salt

Method
 

  1. Preheat oven to 375 degrees F. Spray a 9x13 casserole dish with non-stick cooking spray.
  2. Place cauliflower florets and 3 tablespoons of water in a large microwave safe bowl. Cover with damp paper towels and microwave 7-8 minutes, steaming until tender.
  3. In another large bowl, combine half of each cheese, half of the bacon, sour cream, cream cheese, mustard, herbs and spices, mixing well. Add the steamed cauliflower florets and the water from the bowl, tossing gently until coated.
  4. Transfer mixture to prepared baking dish and top with remaining cheese and bacon.
  5. Cover with foil and bake for 20 minutes. Remove foil and bake another 5-10 minutes or until cheese is bubbly and beginning to brown. If desired broil for 1-2 minutes at the end for browned crispy cheese topping!
  6. Serve immediately.

Notes

- For the crispiest bacon bits, cook them in a skillet until extra-crisp before crumbling. This adds a lovely texture contrast to the creamy casserole.
- If you prefer a firmer cauliflower, reduce the microwave steaming time by a minute or two. The goal is tender-crisp, not mushy.
- Make-ahead: Assemble the entire casserole, cover it tightly with foil, and refrigerate for up to 24 hours. When ready to bake, add an extra 10-15 minutes to the initial covered baking time. This cauliflower casserole stores well in an airtight container in the fridge for up to 5 days, perfect for meal prepping.
