Thawing Your Frozen Green Bean Casserole

Once you’re ready to enjoy your frozen green bean casserole, use one of these thawing methods:

• Refrigerator thawing: For slower thawing, place the frozen casserole in the refrigerator about 24-48 hours before you want to eat it. Allow extra time for very large portions.

• Cold water thawing: For faster thawing, submerge the frozen casserole (still in airtight container) in a bowl or sink of cold tap water. Change water every 30 minutes. Takes 2-3 hours.

• Microwave thawing: For quick results, microwave frozen casserole in 2-3 minute intervals, checking between sessions. Rotate dish for even heating. Watch for hot spots.

Safety tips:

• Don’t thaw casserole at room temperature or hot water, as this allows bacterial growth in the “danger zone” between 40-140°F.

• Cook immediately after microwave thawing for food safety. Partial thawing can cause uneven cooking.
