Focaccia bread is a flat, yeasted italian bread traditionally topped with olive oil, fresh herbs and coarse salt. This recipe for gluten-free focaccia bread is free of gluten, dairy, eggs, soy, corn, beans and nuts, ideal for those with multiple food intolerances. It's a delicious appetizer or snack, dipped in marinara sauce. If you like, you can substitute gluten-free beer for the water for extra-yeasty flavor. For convenience, you can make the dough ahead of time and refrigerate until you're ready to bake it fresh.
