Instructions

  1. Step 1: Cook 6 strips of chopped bacon in a large pot over medium heat until crisp, about 5 minutes; remove bacon with a slotted spoon and set aside, leaving 2 tablespoons of bacon fat in the pot.
  2. Step 2: Add 1 finely diced medium onion to the pot with the bacon fat and cook for 5 minutes until golden and translucent.
  3. Step 3: Add 3 minced garlic cloves and cook for 1 minute until fragrant, then stir in 4 cups of cauliflower florets and cook for 2 minutes to toast lightly.
  4. Step 4: Pour in 4 cups of low-sodium chicken broth, bring to a simmer, cover, and cook for 15 minutes until cauliflower is fork-tender.
  5. Step 5: Remove the pot from heat, blend the soup until smooth using an immersion blender, then return to low heat.
  6. Step 6: Stir in 1/2 cup heavy cream, 1/4 cup shredded cheddar cheese, 2 tablespoons grated Parmesan, and 1/2 teaspoon dried thyme; heat gently for 5 minutes until cheese melts and soup is warm (do not boil).
  7. Step 7: Stir in the reserved crispy bacon, season with salt and black pepper to taste, and garnish with fresh chives before serving.
