This Crockpot creamy mushroom soup is rich, savory, and simple to prepare. Fresh mushrooms, onion, garlic, thyme, broth, and cream slowly cook into comforting homemade soup.

About This Crockpot Mushroom Soup

Slow-cooked mushroom flavor

Slow cooking allows mushrooms, onions, garlic, and thyme to blend into a savory broth.

Creamy but not heavy

Half-and-half creates a smooth finish without making the soup excessively rich.

Choosing mushrooms

Button, cremini, or mixed fresh mushrooms all work well.

Homemade comfort food

Serve it as lunch, a starter, or a light dinner with crusty bread.

Crockpot Creamy Mushroom Soup Ingredients

Mushrooms and aromatics

Use evenly sliced mushrooms, diced onion, and minced garlic.

Broth and cream

Vegetable broth makes the recipe vegetarian; chicken broth creates a richer flavor.

Flour and butter

A small amount of flour thickens the soup. Use gluten-free flour if needed.

Seasonings

Thyme, salt, pepper, nutmeg, and parsley complement earthy mushrooms.
