Absolutely not. Many bread recipes will call for a dutch oven to replicate the steam ovens at bakeries, and it's a favorite method for making homemade bread. However, you don’t need to spend hundreds of dollars to have delicious bread. You can place a pan of water below a baking dish, baking sheet, pizza stone, baking stone, or loaf pan in the oven to create a steamy environment. Or, you can try this trick from Bon Appetit and use a roasting pan to mimic the effects of a dutch oven.
