How do you refresh bagels and baguette loafs?
Use the "Reheat" mode at 300 degrees F for a 9 minute duration. It will fill the oven with steam for the first 6 minutes. The last 3 minutes will be spent drying out the interior and raising the temperature up to 300 degrees F.
Check out the Wolf Steam Oven Chart. Perhaps you didn't get one of these with your oven.
