Keto Cauliflower Soup (Instant Pot)

Keto Cauliflower Soup (Instant Pot)

Adapted from Carla Lybarger’s “Keto Instant Pot Soup (Low Carb)” on Allrecipes.


  • 2 heads of cauliflower
  • 1 onion
  • 1 bell pepper
  • 2 cloves of garlic
  • 1 TBSP olive oil
  • 1 TBSP onion powder
  • 4 cups chicken broth
  • 2 cups shredded cheddar cheese
  • 1 cup half and half
  • 6 slices precooked bacon
  • 1 TBSP spicy brown mustard
  • 8 drops hot pepper sauce
  • 1/8th teaspoon liquid smoke
  • Salt and pepper to taste
  • Optional: sour cream, green onions


If you are new to Instant Pot cooking, be sure to consult your manual before attempting. Using the saute function on your Instant Pot, fry chopped onions and minced garlic in olive oil until lightly browned. Add chopped cauliflower, bell pepper, chicken broth, and onion powder. Put the lid on the Instant Pot, make sure that the vent is NOT open. Select Soup Function, and set the pot for 15 minutes. The soup will actually take a little longer than 15 minutes, as it takes a little time for the pressure to build. Using the Quick Release method, let all of the steam out of the pot before opening. When it is safe, remove lid and add remaining ingredients: cheddar cheese, half and half, chopped bacon, spicy brown mustard, hot pepper sauce, liquid smoke, salt, and pepper. After selecting the Keep Warm setting, stir until cheese is fully melted. If you would like this soup to taste a little more like baked potato soup, garnish with green onions and sour cream.
