Instructions
Step 1: Sauté the Aromatics
In your soup pot, heat the olive oil or butter over medium heat. Add the chopped onion, celery, and carrots and sauté until softened, about 6–8 minutes. Stir in the garlic and cook for another minute until fragrant.
Step 2: Add Mushrooms
Toss in the sliced mushrooms and cook for 7–10 minutes, stirring occasionally. They’ll release moisture, then start to brown. This step is key to building the savory base found in the best mushroom soup recipes.
Step 3: Toast the Barley
Add the rinsed barley to the pot and stir for a minute to lightly toast it. This boosts its nutty flavor and helps it hold up better in the soup.
Step 4: Deglaze and Simmer
Pour in your chicken broth, scraping the bottom of the pot to release any brown bits. Add your dried herbs, bay leaf, and season with salt and pepper. Bring everything to a boil, then reduce to a simmer. Cover and let it cook for 30 minutes, or until the barley is tender.
Step 5: Add Chicken and Cream
Stir in the shredded chicken and your choice of milk or half-and-half. Let the soup simmer gently for another 10 minutes. If you’d like it a bit thicker, whisk 2 tablespoons of flour into a splash of milk before adding it to the pot.
Step 6: Final Touches
Taste and adjust seasoning. Add a splash of lemon juice or a dash of soy sauce for brightness and depth. Remove the bay leaf and serve hot.
