A Dutch oven is neither Dutch nor an oven—it is a deep covered pot that you can use on the stove or in the oven. It usually refers to a pot that holds between three and six quarts, although the size can vary. A deep oven-proof skillet can work, as can an oven-proof soup pot. And if your recipe doesn't call for putting the pot in the oven at all, any heavy deep pot will do.
