How to defrost bread so it tastes fresh

updated 11 July 2026

Quick answer

A whole loaf is best defrosted and refreshed in an oven heated to 150-160°C (300-320°F) for 15-25 minutes. Toss slices straight from the freezer into a toaster or air fryer and crisp them for a few minutes. If you have time, simply leave the bread at room temperature for 1-2 hours.

Step by step

  1. 1

    A whole loaf in the oven

    Heat the oven to 150-160°C (300-320°F) and put the frozen loaf in for 15-25 minutes, depending on size. A standard loaf of about half a kilogram (1 pound) needs around 20 minutes, a smaller one 15. If you're worried the crust will brown too much, wrap the bread in aluminum foil and take it off for the last 5 minutes so the crust gets its crunch back.

  2. 2

    Slices in a toaster or air fryer

    Single slices don't need defrosting first, so put them frozen straight into the toaster on a slightly longer setting, or use the defrost function if your toaster has one. In an air fryer, set about 160-180°C (320-355°F) and crisp for 3-5 minutes, flipping halfway. It's the fastest way to get one or two slices ready for breakfast.

  3. 3

    Refresh rolls and buns with a splash of water

    Sprinkle or spray frozen rolls, croissants, or challah with a little water and put them in an oven heated to 160-180°C (320-355°F) for 5-8 minutes. The water turns to steam, which makes the crust crisp and the inside soft. Small baked goods come back from the freezer fastest because they're thin.

  4. 4

    The slow way at room temperature

    Take the bread out of the freezer and leave it on the counter in its bag or under a kitchen towel. Slices come around in 20-30 minutes, a whole loaf in 1-2 hours. Keep the bread in the bag so the moisture returns to the crumb instead of escaping.

  5. 5

    In a hurry, use the microwave

    Wrap a slice in a damp paper towel or set a cup of water next to it, and heat in short 10-15 second bursts. Use a low defrost power instead of full power so the bread doesn't toughen in seconds. The microwave defrosts instantly, but bread defrosted this way goes hard fast, so eat it right away and treat this method as a last resort.

  6. 6

    Refresh the crust at the end

    Bread from the microwave or the counter can end up soft with no crunch. If you have a moment, put it in an oven or air fryer heated to 160-180°C (320-355°F) for 3-5 minutes. The crust will crisp up again while the inside stays soft.

Freeze bread in slices, not whole

How you freeze makes the biggest difference. If you slice the loaf before it goes into the freezer, you can take out exactly as many slices as you need and defrost them in a minute in the toaster. A whole frozen loaf has to be defrosted whole, because you can't cut a single slice off it. If you're worried the slices will fuse into a block, separate them with pieces of baking paper, or freeze them loose on a tray first and then tip them into a bag.

Freeze bread as fresh as possible, ideally the day you buy or bake it. Pack it tightly in a zip-top bag or plastic wrap, squeezing out the air, so it doesn't dry out or pick up freezer smells. Stored like this, it keeps well for about 3 months.

Sourdough versus wheat bread

Rye sourdough bread handles freezing and defrosting exceptionally well thanks to its dense, moist crumb - after a refresh in the oven, it's hard to tell from fresh. Wheat rolls and sandwich bread are more delicate and dry out more easily, so a short bake with a little moisture does them particular good. Wheat bread is best eaten within a month of freezing, while a dense rye loaf will comfortably last two or three.

Avoid freezing bread twice. Defrosted and refrozen bread loses its structure, crumbles, and goes stale much faster. If you've defrosted more than you'll eat, grate the leftovers into breadcrumbs or cut them into croutons instead of putting the loaf back in the freezer.

Frequently asked questions

How do I defrost bread in the oven?

Heat the oven to 150-160°C (300-320°F) and put the frozen loaf in for 15-25 minutes. Wrap a larger loaf in aluminum foil and remove it for the last few minutes so the crust browns. Let the bread rest a moment before slicing.

How do I defrost bread fast?

Slices are fastest, because they go straight from the freezer into the toaster or into an air fryer for 3-5 minutes. A whole loaf is most efficiently refreshed in the oven in 15-25 minutes. The microwave defrosts in seconds, but bread hardens quickly afterwards.

How do I defrost bread in an air fryer?

Set the air fryer to 160-180°C (320-355°F) and put in slices or a smaller loaf. Crisp slices for 3-5 minutes, flipping halfway, and a bigger piece for 6-10 minutes. The air fryer refreshes the crust nicely, so the bread comes out crisp.

Do I need to defrost bread before eating it?

Not slices - a toaster or air fryer handles them straight from the freezer. A whole loaf is more convenient to defrost first, in the oven or on the counter. For packed sandwiches, slices defrost on their own by lunchtime.

Can I refreeze defrosted bread?

For quality's sake it's better not to, because the bread loses structure and goes stale faster. If you've defrosted too much, turn the surplus into croutons, breadcrumbs, or a casserole topping. It's far better to freeze bread in portions or slices from the start.
