Preheat oven to 400 degrees. Wash and cut potatoes if they are a bit bigger. Add to cocotte. In another cocotte or small bowl, combine chicken broth, lemon juice, garlic, dill, za'atar, salt and pepper. Mix well until combined.
Pour over top the potatoes and baked covered, for about 40-50 min or until the potatoes are soft.
Top with feta crumbles, more lemon juice and fresh dill. Enjoy!
