Instant Pot Cream of Mushroom Soup

Instant Pot Cream of Mushroom Soup features quartered mushrooms, sliced onions, and garlic cooked under pressure with dried herbs and seasonings, then pureed for a partly smooth texture with some mushroom pieces. Heavy cream and cornstarch are added afterwards to thicken the soup, which is garnished with fresh thyme and parsley. This preparation offers a rich, creamy mushroom soup made efficiently in a pressure cooker.

Description

Instant Pot Cream of Mushroom Soup combines fresh mushrooms, sweet onions, garlic, and a blend of dried herbs—thyme, rosemary, Italian herbs—with mild heat from red pepper flakes. The ingredients are pressure cooked in chicken broth to extract rich flavors and soften the vegetables. After natural pressure release and opening the pot, the soup is pureed using an immersion blender to achieve a creamy consistency while leaving some mushroom pieces for texture.

A mixture of heavy whipping cream and cornstarch is added and simmered to thicken the soup without boiling, preserving the cream’s smoothness. Additional thickening can be adjusted by mixing cornstarch with water and adding gradually. Fresh thyme and parsley finish the dish with herbal brightness and color.

This soup is suited for a comforting main or side dish, showcasing the earthiness of mushrooms along with a creamy body. The use of an Instant Pot speeds up the cooking time compared to traditional stovetop methods while maintaining depth of flavor.
