How long does it take to thaw bread?

Leave frozen bread wrapped on the counter: about 30 minutes for slices, 1 hour for rolls, and about 3 hours for a whole loaf. Toast slices straight from frozen, or crisp a crusty loaf in a 350°F oven for a few minutes.

MicrowaveOKNot recommended: wrap one slice or roll in a damp towel, microwave 30-45 seconds, and eat right away; it thaws unevenly and turns stale fast.
Cook from frozenOKToast slices straight from the freezer; re-crisp crusty loaves in a 350°F (177°C) oven for a few minutes, covered with foil if browning.

After it's thawed

No official refreezing guidance for bread was found; FSIS refreezing rules address perishable foods such as meat, poultry, and seafood.

Never thaw it this way

  • On the counter / at room temperature: The outer layer warms into the 40-140°F (4-60°C) danger zone, where bacteria multiply rapidly, while the center is still frozen.
  • In hot water: Same problem: the surface sits in the danger zone. FSIS's cold-water method uses cold tap water changed every 30 minutes.

Can I thaw bread in the microwave?

In a pinch: wrap one slice or roll in a damp towel and heat 30-45 seconds, then eat it right away. King Arthur doesn't recommend it.

How do I refresh thawed crusty bread?
