How to Reheat Lamb: Tender Results Every Time
Lamb is the dish people most often undo at the last step. It has spent hours breaking down its connective tissue into gelatine, and that work is what makes it tender — but it also means the meat has very little margin if you rush the defrost or guess at the oven.
The times below are the ones published on each product page, not general advice. Where a dish has no published time we have said so rather than invent one.
At a glance
- Defrost
- Fridge only. A full 36 hours for the serves-4 shoulder
- Oven
- 190°C for the lamb shoulder — hotter than most people expect
- Time
- 35–40 minutes from defrosted, 60–70 from frozen
- Never
- Defrost on the bench or under hot water
Step one: defrost in the fridge
Move the lamb from the freezer to the fridge, on a plate or in a shallow dish to catch the juices. The 12-Hour Slow Cooked Lamb Shoulder is the largest thing on the menu and needs the full 36 hours to defrost to the centre. Smaller portions like the lamb kofta are done overnight.
Do not defrost at room temperature or under hot water. The outside sits in the danger zone for hours while the middle is still solid, and you get a worse result besides.
Step two: the oven, at 190°C
This is the part the internet usually gets wrong. A slow-cooked lamb shoulder is not reheated low and slow — the cooking is already done, and a long gentle warm-through just dries it out. The pack specifies a hot oven and a short time.
- Preheat the oven to 190°C and remove the lamb from its vacuum pouch.
- Place the lamb on a tray.
- From defrosted, heat for 35 to 40 minutes.
- From frozen, heat for 60 to 70 minutes.
- Remove the tray carefully. It will be hot, and there will be rendered fat in it.
- Rest for a few minutes before pulling the meat apart.

The kofta trick worth knowing
The lamb kofta tray is safe to submerge. Bring a pot to the boil, drop the sealed tray straight into the simmering water for 10 to 12 minutes, and there is nothing to wash up. It is the most foolproof reheat on the menu, and gluten and dairy free.
Why lamb goes wrong
Three failure modes, in order of how often they happen.
Not defrosted through. A shoulder that went into the fridge yesterday morning is still cold in the middle tonight. You then either serve it lukewarm at the centre or leave it in long enough to dry the outside to leather. Thirty-six hours is not padding.
Oven too cool for too long. Counter-intuitive, but a long warm-through evaporates moisture without ever crisping the outside. The published 190°C gets it hot fast and puts some colour back on the surface.
Carved too early. A few minutes resting lets the juices settle back through the meat. Pull it apart straight out of the oven and they end up on the tray.
Common questions
Should I defrost lamb before reheating?
Yes, in the fridge. A serves-4 shoulder needs a full 36 hours. You can cook the shoulder from frozen at 190°C for 60 to 70 minutes if you have to, but defrosted gives the better result.
What temperature should I reheat lamb at?
190°C for the 12-hour lamb shoulder, on a tray, out of its vacuum pouch. The lamb kofta uses a cooler 160°C oven, or simmering water, or a microwave.
Should I cover it with foil?
The shoulder instructions do not call for it — it goes on a tray uncovered at 190°C. If your oven runs hot and the surface is colouring too fast, foil over the top for the first part of the time is a reasonable adjustment.
Can I reheat lamb on the stovetop?
For lamb in sauce, yes — the Tuscan lamb shanks are specified for stove or oven, and the sauce protects the meat. For a dry cut like the shoulder, the oven is the only method that works evenly.
How do I stop reheated lamb drying out?
Defrost fully, follow the published time rather than guessing longer, and rest it before serving. Most dryness is over-time rather than over-temperature.
