In this easy leftover lamb shepherd’s pie, leftover roast lamb is heated in a flavoursome gravy, topped with soft and fluffy mashed potato, and then baked in the oven until golden and crispy.
What is Shepherds Pie?
Shepherds pie is a classic English dish of lamb topped with mashed potato – essentially a lamb pie.
Traditional shepherds pie is made with lamb mince, but in the recipe I have used leftover roast lamb leg.
My mum often made a lamb shepherd’s pie a day or two after we had had a roast lamb dinner. It was an easy family friendly meal that utilised leftovers, and a delicious recipe for using up leftover roast lamb.
How to make shepherds pie from leftover lamb
- Finely chop the leftover lamb – you can use leftover lamb shoulder or leg.
- Heat through with garlic, fresh rosemary and stock.
- Top with soft mashed potato.
Shepherds Pie is made with lamb, Cottage Pie is made with beef.
Vegetables, such as peas or sweetcorn, or simply leafy salad such as this pear and walnut salad.
Up to 3 days.
Because this is made with leftover lamb, I recommend that you cook the shepherds pie as soon as you have heated the lamb in the carrot and onion stock.
You can however, make the mashed potato a couple of days beforehand.

OMG this was soooooooo good. Had leftover lamb and leftover garlic mashed potatoes so I used those on top. Otherwise followed the recipe and now we are fighting over who gets the leftover shepherds pie🤣
So happy to hear you enjoyed this Sarah! Garlic mashed potatoes on the top sounds sooo good!
Can I use gravy from.the night before Instead of stock
Yes you can, it sounds like a delicious way to use up the gravy Kate 🙂
Hello – I’d like to make this but freeze it. Is it better to freeze the meat part and make potato topping when defrosted? Or make the whole thing and freeze it? I appreciate there’s probably no fixed answer but your professional opinion would be greatly appreciated!
Hi Hannah, you can do either! It really depends on whether you want to cook the mashed potato topping, or have a meal in the freezer that doesn’t need any prep – If you freeze the whole pie, cool it completely before you freeze it, then you can place the shepherds pie in the oven from frozen and cook at 160C/140C fan/320F for 1 hour to 1.5 hours, until the pie is piping hot all the way through. Hope this helps! Robyn
This is such a delicious recipe and an ideal way to enjoy leftovers. We will be doing this from now on when we have roast lamb – I actually think I enjoyed the pie more than I did the original roast 😀
I’m so pleased to hear you enjoyed the pie. I’m the same – I make a lamb roast just so we can then have this pie!
