Step 1

Prepare the following, placing them all in the same large bowl: dice 1 medium yellow onion and 3 medium celery stalks, peel and dice 2 medium carrots, and mince 2 garlic cloves.

Step 2

Heat 2 tablespoons olive oil in a Dutch oven or large pot over medium heat until shimmering. Add the onion mixture, 1 1/2 teaspoons kosher salt, and 1/4 teaspoon black pepper. Cook, stirring occasionally, until softened, about 5 minutes.

Step 3

Pour in 4 cups low-sodium chicken broth. Bring to a boil. Reduce the heat and simmer for 10 minutes. Stir in 2 cups shredded chicken, 2 cups cooked rice, and 1 cup half-and-half, and simmer until the rice is warmed through, 3 to 4 minutes more.
