How to revive stale bread: water, oven and steam, without ruining it

The weekend's loaf has a hard crust and a dry middle, but it is not ruined. With a little water from the tap and a hot oven, it is surprisingly close to freshly baked again in ten minutes. Here is the method that rescues stale bread, plus the mistakes that ruin it.

Why does bread go stale, and can it be saved?

Stale bread is rarely old in the sense of spoiled. What happens is that the starch in the crumb slowly changes structure after baking and binds the water more tightly, so the bread feels dry and crumbly even though much of the moisture is still in there. The good news: the process is partly reversible. Moisture and heat loosen the starch's grip, and the crumb becomes soft and springy again. The effect is temporary, which is why the trick works best on bread you eat the same day.

One important limit: this applies to stale bread. Bread with mouldy spots goes straight in the bin, and frozen bread has its own method, which you will find in the guide on how to freeze bread properly.

The water-and-oven method, step by step

You need neither a steam function nor any special equipment, the tap and the oven are enough. Here is how to do it with a whole or half loaf:

1. 1
   Preheat the oven to 150-200 °C

   The drier the bread, the lower the temperature and a little longer the time. 150-160 °C is safest for really stale bread; 200 °C gives the crispest crust when the bread is only slightly soft.

2. 2
   Wet the crust with water

   Hold the bread under running cold water for a couple of seconds, or stroke over the whole crust with wet hands. The surface should be wet, not soaked through.

3. 3
   Straight on the rack for 5-10 minutes

   The water turns to steam that draws into the crumb, while the crust dries and turns crisp. A large, dense loaf may need a couple of extra minutes.

4. 4
   Let the bread rest before you cut it

   A couple of minutes on a rack, so the steam can settle into the crumb. Cut, and feel the difference.

Whole loaf or slices?

The oven method is made for whole and half loaves, where the crust protects the crumb from the heat. If the bread is already sliced, the toaster is both faster and better: toast the slices as they are, on a medium setting. Dry slices never quite become like fresh bread again, but freshly toasted with butter they make a perfectly good breakfast.

Baguette? Shorter and more gentle

The thin baguette crust is revived the same way, but tolerates less: just a light wetting with wet hands and 5-7 minutes at 200 °C. You will find the full method, and how to keep the baguette crisp from the start, in the guide on how to keep baguettes and crusty bread crisp.

The two mistakes that ruin the bread

Revived bread is perishable, eat it the same day

Be honest with yourself about what you have got: a loaf on borrowed time. As it cools, the starch sets again, often faster than the first time. So never revive more than you can manage to eat, and let the rest go to the toaster or the freezer. You will find more good ways to use up leftover bread in the guide on how to avoid bread waste.

Best of all: bread that never gets the chance to go stale

Reviving is first aid, the lasting solution is storage that slows the drying from day one. The paper bag and an airy bread bin breathe too well and let the moisture escape within a day or two. The plastic bag holds on to the moisture, but traps the condensation inside until the crust softens and mould thrives. Bread needs something in between.

A Bivoks™ bread bag is sewn from cotton and linen with a thin layer of natural beeswax on the inside: the fabric breathes so the condensation escapes, while the wax layer slows the drying. The bread stays fresh for 7-10 days, and the bag closes with a clip, easy to open, even for stiff morning fingers.
