Print Recipe


  • 14.5 ounces chicken bone broth
  • 3/4 cup heavy cream
  • 4 cloves garlic minced
  • 1/2 teaspoon onion powder
  • 1/4 teaspoon poultry seasoning see note
  • 1 teaspoon xanthan gum or glucomannan
  • 32 ounces frozen cauliflower florets or 2 fresh heads cut into florets
  • 16 ounces freshly grated sharp cheddar cheese divided (or preferred cheese)
  • 8 slices no sugar bacon cooked and chopped


  • Combine broth, heavy cream, garlic, onion powder, poultry seasoning, and xanthan gum in medium saucepan.
  • Cook liquid over medium heat, stirring frequently, until thickened. Remove from heat.
  • Mix the cauliflower, cheese, and sauce together in 9x13 casserole pan.
  • Sprinkle the chopped bacon on top then cover with remaining cheese.
  • Bake in 350°F oven for 50 minutes or until browned and cauliflower is tender.



Poultry seasoning can be substituted with a mix of sage, marjoram, thyme, parsley and paprika.
Xanthan gum can add a slimy feel. That why my preferred thickener is glucomannan.
