Cream of Mushroom Soup

Ingredients

Directions

The book gives no cooking times; the times in the steps were added in transcription, so check for doneness rather than trusting the clock.

  1. In a pot, melt the butter over medium heat.

  2. Add the chopped onion and sliced mushrooms; sauté until soft.

  3. Pour in the broth and bring to a boil.

  4. Reduce heat and simmer for 15 minutes.

  5. Stir in the heavy cream and season with salt and pepper.

  6. Blend until smooth, then serve hot, garnished with parsley.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Mushrooms
Provide the main flavor and body of the soup.
Onion
Adds sweetness and aromatic depth as it softens in the butter.
Heavy cream
Adds richness and a smooth, silky texture.
Butter
Carries flavor and adds richness when used to sauté the vegetables.

The step that matters

Stir in the heavy cream. Cream can curdle or separate if boiled hard, so add it after the broth has simmered and keep the soup at a gentle heat once it is in.

Swap the parsley
