Creamy Minnesota wild rice soup with earthy wild rice and vegetables is a comforting Midwestern family tradition. This hearty, healthy soup celebrates the state's native grain in every warming spoonful.
Rinse wild rice thoroughly, then add to a large pot with chicken broth. Bring to a boil over high heat, then reduce to low and simmer, covered, for 45 minutes until tender.
While rice cooks, melt butter in a skillet over medium heat. Add onion, carrots, celery, and mushrooms; sauté for 7–8 minutes until vegetables are soft and fragrant.
Add chicken breast to the pot with wild rice and simmer for 20 minutes, ensuring chicken cooks through. Remove chicken, shred or dice, and return to the soup.
Stir in sautéed vegetables, salt, black pepper, and thyme. Cook for 10 minutes, allowing flavors to meld.
Mix flour with heavy cream to make a slurry. Stir into soup, increase heat to medium-high, and cook 5–7 minutes until the soup thickens. Adjust seasoning and serve hot.
