Craving a warm, comforting bowl of soup without the carb overload? This keto cauliflower soup with bacon is the perfect solution. It's a creamy, flavorful chowder that's easy to make and satisfying, even for those who aren't cauliflower fanatics. This recipe offers a delightful alternative to traditional potato soup, delivering a similar comforting experience with a fraction of the carbohydrates.
Why Cauliflower?
Cauliflower shines as a versatile vegetable, and in this soup, it cleverly mimics the texture of potatoes while keeping the carb count low. The result is a creamy, comforting soup that doesn't feel like a compromise.
Variations and Substitutions
This recipe is easily adaptable to suit different dietary needs and preferences:
- Vegetarian: Substitute avocado oil for bacon fat, use vegetable broth, and omit the bacon topping.
- Dairy-Free: Use coconut cream instead of heavy cream and nutritional yeast for a cheesy flavor.
- Adding More Flavor: Consider roasting the cauliflower before adding it to the pot for a deeper, more complex flavor. Simply spread the cauliflower florets on a parchment-lined baking sheet, drizzle with olive oil, and bake at 400 degrees F for 25 minutes. If roasting, reduce the simmering time in the recipe by half.

The Secret to Crispy Bacon
To ensure perfectly crispy bacon for both the soup base and topping, use the "cold pot" technique. Cut the bacon into small pieces and place them in a cold pot. Cook over medium heat, stirring occasionally, until the bacon is golden brown and crispy. Remove the bacon with a slotted spoon and set aside, reserving the rendered bacon fat.
Step-by-Step Instructions
Here's how to make this delectable keto cauliflower soup:
- Prep the Veggies: Chop all vegetables and set aside.
- Sauté Aromatics: Add bacon fat and butter to a medium/large pot over medium heat. Once the butter begins to bubble, add bell pepper, half a cup of leeks (saving the rest for topping), onion, celery, garlic, and thyme. Sauté until softened.
- Simmer the Soup: Add the cauliflower pieces, chicken broth, cayenne, salt, and pepper. Bring to a boil, then cover and reduce heat to low. Simmer for 10 minutes, or until the cauliflower is tender.
- Make it Creamy: Remove the lid and add softened cream cheese, half a cup of cheddar cheese (saving the rest for topping), and heavy whipping cream. Stir until the cheese is melted and the soup is creamy.
- Thicken (Optional): For a thicker chowder texture, sprinkle 1/2 teaspoon of xanthan gum over the broth and stir well.
- Serve and Garnish: Remove from heat and let cool for a few minutes before serving. Top each bowl with the remaining cheese, leeks, and crumbled bacon.
Tips and Tricks
- Roasting Cauliflower: For a deeper flavor, roast the cauliflower florets before adding them to the soup. Toss with olive oil and roast at 400°F (200°C) for 20-25 minutes, or until tender and slightly browned.
- Blending for Smoothness: If you prefer a completely smooth soup, use an immersion blender to puree the soup directly in the pot. Alternatively, transfer the soup in batches to a regular blender and blend until smooth, then return to the pot.
- Adjusting Thickness: If the soup is too thick, add more broth until you reach your desired consistency. If it's too thin, simmer uncovered for a few minutes to allow some of the liquid to evaporate.
- Spice it Up: Add a pinch of red pepper flakes or a dash of hot sauce for an extra kick.
- Make Ahead: This soup can be made ahead of time and stored in the refrigerator for up to 3 days. The flavors will meld together even more overnight.
- Freezing: Allow the soup to cool completely before transferring it to an airtight container. Freeze for up to 2-3 months. Thaw overnight in the refrigerator before reheating.
