Can I freeze bread dough, and at what stage?

Freezing does not stop fermentation instantly and it does kill a proportion of the yeast, particularly on slow freezing and long storage. Both facts shape the practical advice: freeze fast, use within a month or so, and expect a slower, less vigorous final rise than the same dough would give fresh. Some bakers add a little extra yeast to dough destined for the freezer, which is reasonable for a straight yeasted dough and not worth doing for sourdough.

What you'll need

• A baking tray that fits your freezer
• Freezer bags or an airtight box
• A little oil (optional)

Step by step

1. Decide the stage.After mixing and kneading but before the first rise gives the most flexibility and the slowest thaw. After the first rise and shaping is the most convenient: it thaws, proves and bakes. After the final prove is not worth doing — the risen structure collapses on freezing.
2. Freeze fast and freeze it flat.Shape the rolls or loaf and put them on a lined tray in the freezer uncovered until solid, typically two to three hours. Fast freezing makes smaller ice crystals and kills less yeast. Only bag them once hard, or they will deform and stick together.
3. Wrap tightly and label with the date.Oil the surface lightly, then bag with the air pressed out. Dough dries and cracks in the freezer, and freezer burn on the skin becomes a hard patch that never proves.
4. Use it within about a month.It stays safe far longer but the yeast keeps dying. At three months a dough may take most of a day to prove, or fail to rise at all. Enriched doughs with sugar and fat keep slightly better.
5. Thaw overnight in the fridge.Slow thawing in the fridge is far kinder than a warm room, where the outside starts fermenting while the middle is still frozen. Leave it covered and loosely wrapped so it can expand.
6. Allow a long final prove.Bring to room temperature and then let it prove until visibly puffy and passing the poke test — the surviving yeast is doing the work of a full population, so twice the usual time is not unusual. Judge by the dough, never the clock.
7. Bake as normal.No temperature adjustment is needed. If anything, previously frozen dough browns very slightly less, so a couple of extra minutes may help.

Tips

• Portion rolls individually. A tray of frozen rolls you can take three of is far more useful than one frozen block of dough.
• Enriched doughs — brioche, cinnamon buns, hot cross buns — freeze well shaped, and are the case where this genuinely saves the most work on the day.
• Sourdough freezes less predictably because the culture is slower to recover. Cold retarding is the better tool for sourdough.
• Pizza dough is the one people freeze most successfully, because a slightly under-risen base is no bad thing.

Common mistakes

• Freezing dough after its final prove — The gas structure collapses as it freezes and does not come back. All the proving work is lost.
• Thawing on the worktop in a warm kitchen — The outside ferments and over-proves while the centre is still ice. The fridge overnight avoids this completely.

If it doesn't work

Alternatives

• Freeze the baked bread instead: Almost always better. Bread freezes superbly, thaws in an hour, and refreshes in a hot oven for five minutes with no proving involved. See `freeze-bread-properly`.
• Cold-prove in the fridge instead of freezing: Up to 48 hours in the fridge gives you the same ready-when-you-are convenience, better flavour, and no yeast losses at all. See `cold-prove-dough-overnight`.
• Par-bake, then freeze: Bake to a set but pale crust, cool, freeze, then finish from frozen in a hot oven. This is how supermarket bake-at-home bread works and it is very reliable.
