In a large pot combine potatoes, onions, garlic, and 1 cup of the broth. Cover and cook over medium 10 minutes or until vegetables are tender, adding water, 1 to 2 tablespoons at a time, as needed to prevent sticking.
Step 2
Add the remaining 5 cups broth and the next seven ingredients (through thyme). Cook 10 to 15 minutes more or until vegetables are tender.
