Keto Mushroom Soup Recipe

This Keto Cream of Mushroom Soup is pure comfort food, and also works as a substitute for canned soup in many recipes. When eating it as a meal, I like to drizzle it with a touch of garlic oil and serve it with a chaffle or other keto-friendly bread.

Ingredients

  • 1/4 cup butter
  • 12 ounces mushrooms sliced
  • 1/2 cup chopped onion
  • 1 teaspoon minced garlic
  • 1 tablespoon fresh thyme
  • 4 cups chicken bone broth or regular broth
  • 3 ounces cream cheese
  • Salt and pepper to taste
  • 1 cup heavy cream

Instructions

Stove Top

  • Melt butter in a large saucepan
  • Add mushrooms, onions, garlic, and thyme.
  • Cook until the mushrooms have released most of their liquid, about 7 minutes.
  • Add chicken broth and cream cheese to the pan, and cook until the cream cheese melts.
  • Season to taste with salt and pepper, and add heavy cream. Simmer for 15 minutes.

Instant Pot

  • Set your Instant Pot to low saute and add butter. When the butter melts add the mushrooms, onions, garlic, and thyme. Cook for 6 minutes. Season to taste with salt and pepper.
  • Add the chicken broth and place the lid on your Instant Pot. Set pressure to high and the timer to 4 minutes.
  • Allow the pressure to release naturally for 10 minutes, and then do a quick release.
  • Set the Instant Pot to sauté, and add the cream cheese. Cook, stirring often, until the cream cheese melts.
  • Turn to warm and stir in cream.
