I ordered 2 loaves of frozen challah bread from Fresh Direct (Shabtai brand) to use in a french toast casserole I'm going to make tomorrow for brunch. I can not figure out now what to do with them-- should I just leave them on the counter to defrost or will they get soggy? Should I pop them in the oven to defrost? There are no instructions of any kind on the label, and I'm a little at a loss. Any suggestions would be welcome. Thanks!
