Step 1

In a 6-quart saucepan or pot, heat the butter and oil until hot over medium heat. Add the carrots, celery, onion, thyme and rosemary and cook, stirring often, until vegetables are slightly tender, 3-4 minutes.

Step 2

Add the broth, rice, salt and pepper. Bring the soup to a simmer and cook, stirring occasionally to prevent sticking, until the rice is tender. The exact time will depend on variety of rice and package directions. For a brown and wild rice blend, the time will be about 30 minutes.

Step 3

Whisk together or blend the half and half and flour until smooth and there are no lumps. Stir the flour mixture into the soup, whisking quickly, and simmer gently until slightly thickened, 5-6 minutes.

Step 4

Stir in the cooked turkey and heat through. Season to taste with additional salt and pepper, if needed. Serve.
