To revive stale bread using an oven, lightly dampen the bread with water, then bake it in a preheated oven at 150-175°C (300-350°F) for 5-10 minutes until warmed through and the crust is crisp again.
Detailed Explanation:
Stale bread isn't moldy bread; it's bread that has lost moisture and whose starch molecules have recrystallized, making it hard. You can often bring it back to life:
- Preheat Oven: Set your oven to a moderate temperature, around 150-175°C (300-350°F). You want it warm enough to heat and re-steam the bread, but not so hot that it toasts or burns.
- Lightly Dampen: This is the key step. Briefly hold the stale bread under running water (don't soak it!). You want the crust to be visibly damp, but not dripping wet. For larger loaves, you can use a spray bottle to mist the surface evenly. For slices, a light brush with water works.
- Bake: Place the dampened bread directly on the oven rack (or on a baking sheet if it's very small) and bake for 5 to 10 minutes. The exact time will depend on the size and staleness of the bread.
- For a whole loaf, it might take 8-10 minutes.
- For individual rolls or slices, 3-5 minutes might be enough.
- Check for Doneness: The bread should feel soft and warm throughout, and the crust should have regained its crispness.
- Serve Immediately: This technique is temporary. Once revived, the bread will go stale again very quickly (often within an hour or two) as it cools and loses its regained moisture. Enjoy it right away!
Pro Tip:
This method works best for crusty breads (like baguettes or boules) that have gone hard. It's less effective for very soft breads or those that are extremely old and moldy (which should be discarded).
