Prepare the Ingredients: Start by dicing the chicken, carrots, celery, and onion. Aim for uniform size for even cooking.
Add to Pot/Slow Cooker: In a large pot or slow cooker, add the diced chicken, wild rice, carrots, celery, onion, and chicken broth.
Season: Add salt and pepper to taste. You can also add any additional herbs or spices you enjoy at this stage.
Cook: If using a slow cooker, set it to low for 6-8 hours, or high for 3-4 hours. For stovetop, bring to a boil and then simmer for about 30 minutes until the rice is tender and the chicken is cooked through.
Finally, Add Cream: Stir in the cream or milk in the last 15-20 minutes of cooking for added richness. (If you prefer a lighter soup, omit this step).
Check Seasoning: Prior to serving, taste the soup and adjust seasoning as necessary. You can also add some fresh herbs for a burst of flavor.
Serve Warm: Ladle the soup into bowls, and enjoy the warmth and comfort of your meal!
