This Mushroom Leek Soup Recipe gives a nice warm and cozy feeling. Creamy potato-based soup with earthy mushrooms and sweet leeks. Made easy in the Instant Pot.

Ingredients

Scale
  • 5 tablespoons butter
  • 8 oz mushrooms, sliced
  • 3 medium leeks, sliced and washed thoroughly
  • 2 carrots, peeled and grated
  • 1 celery stalk, chopped
  • 6 cups chicken broth
  • 5 medium potatoes, peeled and cubed into 1-inch pieces
  • 1 teaspoon salt (adjust to taste)
  • ½ teaspoon black pepper (adjust to taste)
  • ½ teaspoon dried thyme
  • 1 bay leaf (optional)
  • Fresh parsley for garnish (optional)

Instructions

  1. Turn Instant Pot to sauté mode. Add butter and sliced mushrooms. Sauté for 3 minutes, stirring occasionally until mushrooms begin to soften and brown slightly.
  2. Add leeks, grated carrots, and chopped celery. Sauté for 7 minutes, stirring a few times until leeks are soft and translucent.
  3. Add cubed potatoes, chicken broth, bay leaf, thyme, salt, and pepper. Stir to combine.
  4. Cover with lid and move steam release handle to sealing position. Cook on soup/broth mode for 10 minutes. Pot will take 8-10 minutes to come to pressure before cooking begins.
  5. When cooking completes, carefully quick release the pressure by turning handle to venting. Wait until all steam has escaped and the float valve drops before opening lid.
  6. Remove bay leaf. Taste and adjust seasonings as needed. Soup will have a naturally creamy, slightly chunky texture. Ladle into bowls and garnish with fresh parsley. Serve hot with crusty bread.

Notes

  • Recipe requires a 6-quart Instant Pot. For stovetop method, simmer covered for 25-30 minutes after sautéing vegetables.
  • Leeks trap dirt between layers. Slice first, then rinse thoroughly in a colander under cold water.
  • For creamier texture, use an immersion blender to puree half the soup while leaving some chunks.
  • Can substitute half the mushrooms with shiitake varieties for deeper flavor.
  • Yukon Gold potatoes work best for naturally buttery flavor, but russets are fine too.
  • Soup tastes even better the next day as flavors meld together. Add broth when reheating if too thick.
