Regardless of whether you are defrosting this particular loaf or a store bought loaf of bread, defrosting is the same. Frozen bread can be defrosted in a few ways. Here are some of my methods. 1. Wrap frozen loaf or slices in foil and warm in a moderate oven until heated through and defrosted - my preferred method because it tastes like freshly baked bread. 2. Toast slices until defrosted and golden brown. 3. Without removing wrapping, allow to defrost at room temperature or overnight in the refrigerator.
