This cream of mushroom soup recipe for the slow cooker delivers deep, earthy mushroom flavor together with smooth butter and rich cream. It starts with fresh button and dried shiitake mushrooms slow cooked with herbs, spices, savory chicken stock, and a splash of sherry. A garnish of sautéed mushrooms and a sprinkling of dill adds the perfect finishing touch.

Prepping Dried Mushrooms

A quick way to hydrate your dried mushrooms is to place them in a medium-sized bowl and cover with water. Microwave on high for 30 seconds and wait 5 minutes before adding the mushrooms to your recipe.

You could skip pre-soaking your mushrooms for this recipe, but it's not recommended. Dried mushrooms usually contain at least a few bits of grit. By soaking first, the dirt releases into the hot water and not into your hot soup. You don't have to lose flavor either. Just pass the soaking water through a coffee filter and add it back into your soup.
