I would avoid using frozen bread. Using frozen bread combined with the egg and milk mixture, will result in soggy French toast. Instead, take the frozen bread out of the freezer and let it defrost overnight in the refrigerator. If you forget, no worries - simply remove the frozen slices from the loaf and let them defrost quickly on the countertop while you prepare the rest of the ingredients. Within 20 to 30 minutes, the slices will be ready to use. Follow these steps for delicious, non-soggy French Toast every time.
