Cream Mushroom Soup

This from-scratch cream of mushroom soup proves you don’t need a pantry full of ingredients to make something that tastes luxurious. Fresh mushrooms, milk, butter, and flour. That’s the whole list.

Cooking the mushrooms in a double boiler for 20 minutes is an old-fashioned technique that extracts their flavor gently without browning. The mushroom-infused water becomes part of the soup base, so no flavor goes to waste. When the milk goes in, you’ve got a broth that tastes deeply of mushroom without needing stock or bouillon.

The thickening method is classic beurre manie: butter and flour rubbed together into a smooth paste, dissolved in a bit of hot milk, then stirred back into the soup. It thickens without lumps and creates a velvety consistency. A spoonful of whipped cream in each bowl is the finishing touch.

Kitchen Tips

• Chop the mushrooms fine so they release maximum flavor into the cooking liquid during those 20 minutes.
• Dissolve the butter-flour paste in a small amount of hot milk before adding to the pot. Dumping it straight in creates stubborn lumps.
• Boil briefly after adding the flour mixture to cook out the raw flour taste. Under-cooked flour leaves a starchy, pasty mouthfeel.

Variations

• Wild mushroom version: Use a mix of cremini, shiitake, and oyster mushrooms for a more complex, earthy flavor.
• Garlic boost: Add a minced clove of garlic to the mushrooms while they cook for extra savory depth.
