Creamy cauliflower cheese soup topped with bacon

This cheese soup with cauliflower is a game-changer for anyone watching their carbs. Unlike traditional loaded potato soup, this version uses cauliflower for a fraction of the carbs while delivering all the creamy, cheesy satisfaction you crave.

Cauliflower is the perfect vegetable for cheese soup because it has a mild flavor that lets the cheese shine while becoming wonderfully tender and creamy when cooked. Blend part of it to create a naturally thick base without any flour.

Why Cauliflower?

Cauliflower is a keto superstar:

  • Low carb - Only 5g carbs per cup
  • High fiber - Keeps you full
  • Mild flavor - Takes on cheese beautifully
  • Creamy texture - When blended, mimics potatoes
  • Nutritious - Vitamins C, K, and B6

Making It Keto-Friendly

  • No flour needed - cauliflower thickens naturally
  • Use heavy cream instead of milk
  • Add extra cheese for fat content
  • Top with bacon for protein

Ingredients

Instructions

  1. Sauté aromatics. Melt butter in a large pot over medium heat. Add onion and cook 5 minutes until soft. Add garlic, cook 1 minute.
  2. Cook cauliflower. Add chicken broth and cauliflower florets. Bring to a boil, then reduce heat and simmer 15 minutes until cauliflower is very tender.
  3. Create texture. Using an immersion blender, blend about half the soup until smooth, leaving the rest chunky. (Or remove half, blend in a blender, and return.)
  4. Add dairy. Reduce heat to low. Stir in heavy cream. Add cheddar and Parmesan gradually, stirring until completely melted.
  5. Season and serve. Stir in mustard powder. Season with salt and pepper. Ladle into bowls and top with crispy bacon and chives.

  • Extra creamy: Blend all the cauliflower for silky smooth texture.
  • More cheese: Add smoked Gouda or Gruyère for variety.
  • Vegetarian: Use vegetable broth and skip the bacon.
  • Net carbs: Only 7g net carbs per serving (10g total - 3g fiber).
