Keto Mushroom Soup Recipe | Instant Pot or Slow Cooker

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

  • ¼ cup butter
  • 12 ounces mushrooms sliced
  • ½ 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.

Notes

Store in airtight containers in the fridge for up to four days, or freeze for up to three months.  Reheat on the stovetop or in the microwave.
