Ingredients

  • 1/4 cup salted butter
  • 1 large yellow onion diced
  • 3 cloves garlic minced
  • 1/2 cup all purpose flour divided
  • 8 cups chicken stock or vegetable broth
  • 1 large head cauliflower cut into large chunks, leaves removed
  • 2 bay leaves
  • salt & pepper to taste
  • 1/2 teaspoon thyme thyme leaves, not ground thyme
  • 1 cup Half & Half
optional toppings:
  • cheddar cheese grated
  • Bacon cooked and crumbled
  • and/or parsley

Instructions

Slow Cooker Directions
    Cup of Yum
  1. In a medium skillet, melt butter over medium heat. Sauté onion until brown. Add in garlic and cook another minute until fragrant. Sprinkle with 1/4 cup flour and stir to moisten the flour and cook briefly. Pour onion mixture into the bottom of a crockpot.
  2. Whisk in chicken stock to crockpot and then stir in cauliflower pieces, bay leaves, salt, pepper and thyme. Cover and cook on high 3-4 hours or until fragrant and cauliflower is very tender.
  3. Remove bay leaves from crockpot. Blend soup in a high powered blender until very smooth. Soup should thicken up once blended, but still be on the thinner side.
  4. Measure half and half into a microwave-safe large bowl or larger glass liquid measuring cup. Whisk in remaining 1/4 cup flour until smooth. Slowly whisk in 3 cups of hot soup to the half and half. Microwave for 3 minutes, whisking every 30 seconds. This mixture should become very thick. Pour into crockpot and whisk to combine to create a creamy, thick soup. Taste and adjust seasonings. Serve with cheese, bacon and parsley.
