How to Make It
Heat a large Dutch oven over medium-high heat. Add oil; swirl to coat. Sprinkle chicken with 1/4 teaspoon salt. Add chicken to pan; cook 5 minutes or until browned, stirring occasionally. Remove chicken from pan.
Add onion, celery, carrot, rosemary, and thyme to pan; cook 7 minutes or until vegetables are tender. Add 4 cups stock, scraping pan to loosen browned bits. Bring to a boil; reduce heat, and simmer 8 minutes. Add gnocchi to pan; cook 3 minutes or until gnocchi float to the surface.
