In a large soup pot over medium heat, melt the butter.
3 tablespoons unsalted butter
Add in the vegetables. Then season with thyme, salt, and pepper. Stir regularly, sautéing until the vegetables are tender, about 7 to 10 minutes.
1 small yellow onion, 2 cloves garlic, 2 medium carrots, 3 celery stalks, 2 teaspoons dried thyme, 1 teaspoon kosher salt, 1/4 teaspoon black pepper
Stir in the flour, allowing it to fully coat the vegetables.
1/3 cup all purpose flour
Very slowly stir in the chicken broth, scraping up the browned bits at the bottom of the pot. Start with just a little at a time, about two tablespoons, only adding more once the last bit is absorbed. Don't rush this step, but it also shouldn't take more than about a minute.
4 cups chicken broth
Stir in the chicken and bay leaves and bring the soup to a low boil, continuing to stir. Simmer the soup for 5 minutes to let the flavors meld. Then stir in the heavy cream and the peas. Taste the soup and adjust the seasonings, adding more salt and pepper to taste.
3 cups shredded rotisserie chicken, 1 cup heavy cream, 1 cup frozen peas, 2 bay leaves
Serve the soup with biscuits and enjoy!
