Loaded Keto Cauliflower Soup

Topped with sharp cheddar cheese, crunchy bacon bits, and a dollop of sour cream, this keto cauliflower soup recipe tastes like a baked potato bar — without as many carbs, of course.

French fries, tater tots, scalloped potatoes, baked potatoes, American fries, breakfast potatoes, shall we go on? Potatoes are one of the most versatile and — let’s just go ahead and say it — beloved vegetables out there. These starchy tubers also contain their fair share of carbohydrates, which may spike your blood sugar more than a slice of white bread (1).

In this recipe, you’ll blend cauliflower florets with beef bone broth to make a faux loaded potato soup. By simmering the cauliflower in broth until fork tender, then blending it in a Vitamix or food processor, you’re left with a thick, creamy soup that tastes just like traditional potato soup.

Why Cauliflower Makes the Perfect Substitute for Potatoes

If you’re a recovering starch fiend new to the keto diet, you probably know that cauliflower makes an excellent substitute for your former favorite foods. Cauliflower has been baked into biscuits, rolled out into pizza crusts, grated into rice, and even baked under layers of cheddar and American cheese as a faux mac ‘n’ cheese, making it perfect for any low-carb diet.

While a cauliflower pizza crust might not satisfy your pizza cravings, cauliflower is remarkably similar to potatoes in taste, making it a viable substitute. Cauliflower can be mashed, roasted, or smothered in butter to give a taste that’s similar to potatoes, but much lower in carbs. A cup (or 100 grams) of cauliflower contains less than 3 grams of net carbs per serving and also contains dietary fiber, fitting nicely into any keto meal plan. Meanwhile, 100 grams of white potatoes contain 19 grams of net carbs (2).

Recipe Notes and Alterations

Hopefully, you’ll find this low-carb recipe fairly easy to follow. Just in case, here are a few tips that might make the process a little easier:

Use an Immersion Blender

The recipe below is a blended soup. Meaning, you are going to have to pour a very hot liquid into your food processor or blender to give it the perfect, creamy texture you’re looking for. If you’ve never attempted this before, know this: Many home chefs have spent hours scrubbing their counters, floors, and alas, their ceilings due to an exploding hot liquid in their blender. When you blend this recipe (step five in the recipe instructions), you will need to hold down firmly on your blender, preferably with an old towel wedged between your palm and the lid.

Or, you could go the simpler route: Use an immersion blender.

An immersion blender is a handy kitchen gadget that allows you to blend liquids together (like hearty soups and bisques) without having to pour your concoction into a food processor. Not only does that cut down on the dishes you’ll have to scrub by hand, but it can prevent a major — major — mess in the kitchen.

Substitute Coconut Cream for Heavy Cream 

This low-carb soup uses three types of dairy: sour cream, shredded cheese, and heavy cream. If you think this much dairy will be a tad harsh on your stomach, feel free to swap out heavy cream for coconut cream of full-fat coconut milk. It will alter the taste slightly, but the chives and garlic will cut through the coconut enough that you won’t notice a difference.

Loaded Cauliflower Keto Soup

This low-carb cauliflower soup tastes just like traditional loaded baked potato soup, without the extra carbs. Cauliflower florets are blended with beef bone broth and heavy cream to create a rich, creamy soup that resembles a bisque. Top with chives, bacon bits, and sharp cheddar cheese to complete the dish.
Course Soup
Prep Time 5 minutes
Cook Time 20 minutes
Total Time 25 minutes
Servings 8


  • 8 strips bacon
  • 1 Tbsp. extra virgin olive oil
  • 1 sweet onion chopped
  • 3 Tbsp. minced garlic
  • 1 Tbsp. onion salt
  • 1/2 tsp. red chili flakes
  • 3 Tbsp. fresh chives
  • 4 cups Kettle & Fire Beef Bone Broth
  • 2 heads cauliflower florets
  • 2 cups heavy cream
  • Green onions for garnish
  • Shredded cheddar cheese for garnish
  • Sour cream for garnish


  1. Heat a large cast iron pan or skillet over medium-high heat. Place the bacon in the pan, cooking until crispy, or roughly two minutes per side. Set aside.

  2. While the bacon is cooking, heat a large soup pot or Dutch oven medium heat. Drizzle olive oil in the pot, then add the chopped onion. Add the garlic, onion salt, red chili flakes, and chives to the large pot with the onion.

  3. When the onion is translucent, but not caramelized, add the beef bone broth. Add the cauliflower florets, and cover. Cook for 15 minutes, or until fork-tender.

  4. While the cauliflower is simmering, prepare your garnishes. Chop the bacon and green onion.

  5. Remove the cauliflower from heat, carefully pouring into a high-powered blender or food processor. Blend in batches, as only half the mixture will fit into your food processor at one time. Hold tightly to the lid, as the heat will cause excessive pressure while blending.

  6. Once fully blended, return the cauliflower mixture to the soup pot, turning the burner back to medium heat. Stir in the heavy cream and bacon bits, reserving some bacon to be used as a garnish. Continue to cook for 5 minutes.

  7. Pour soup into serving bowls. Top with bacon, green onions, cheddar cheese, and sour cream. Serve.
