Ingredients For Leftover Lamb Pie with Mint

When I make my leftover roast lamb pie, I use:

Cooking Spray – Or olive oil.

Onion – Finely chopped or diced. 

Leftover Roast Lamb – Chopped into bites. 

Plain Flour

Salt and Pepper

Red Wine

Carrots – This is technically a lamb and vegetable pie, too!

White Potatoes – A lamb and potato pie recipe is ideal for leftovers when you might not have much meat. 

Lamb Stock – Use beef stock if you don’t have lamb.

Henderson’s Relish – Henderson’s is pretty region-specific. You can use Worcestershire sauce or skip it if you can’t get any. 

Mint Sauce 

Ready-Made Shortcrust Pastry – Either a block or pre-rolled, which you might need to roll out to a different size and shape to fit your tin. 

Egg – This is just for the egg wash; it’s not essential, and you could also use milk. 

Butter – This is just to grease your tin. You can use margarine instead. 

You’ll Also Need

Homemade pie with leftover lamb is super easy to make, so you don’t need much. I use:

• Peeler, chopping board and sharp knife to prepare the ingredients for the lamb pie recipe. 
• Jug and whisk for the stock.
• Cast Iron Dutch Oven. Any large, flameproof pan or dish is fine, but I like to use my big dish. A large nonstick frying pan would be great. 
• Pie tin or dish. I use a deep 8-inch square cake tin. If yours is significantly different in size, you might have to adjust the quantities. 
• Pastry Brush

How to Make Leftover Lamb Mint and Potato Pie – Step-by-Step Instructions

Full, easy-to-follow instructions and quantities are available in the recipe card at the bottom of this post.

Step One

Liberally mist a flameproof, non-stick cooking dish or pan with cooking spray or a tablespoon of olive oil and warm over medium heat on the hob. 

Step Two

Add the onions and fry for 5 minutes until soft, stirring often. 

Step Three

Add the cooked lamb, a tablespoon of flour and a pinch of salt and pepper. Stir together well. 

Step Four

Cook for two minutes, stirring often. The flour will start to stick to the lamb. 

Step Five

Pour in the wine and scrape the bottom of the pan. 

Step Six

Bring to a simmer and cook for 3 minutes, stirring often. This stops the flour from clumping together. 

Step Seven

Add the carrots and potatoes. Stir. If your cooking dish is quite full, this might be tricky. Just do your best; it doesn’t matter much.

Step Eight

Pour in the stock and add a splash of Henderson’s relish. 

Step Nine

Stir well and bring to a simmer. 

Step Ten

Simmer for 30 minutes, stirring occasionally, until the sauce has reduced. Reduce the temperature if necessary to achieve a nice, steady simmer. 

Step Eleven

Remove from the heat. Your sauce should have reduced quite a bit. If it’s still watery, simmer for up to ten minutes more. 

On the other hand, stir in a cup of water if it ever becomes too dry. 

Step Twelve

Stir in the mint sauce. Add more or less, depending on your preference. I used to only add a teaspoon or two. The kids were fussier when they were younger but don’t mind a stronger flavour nowadays. 

If you aren’t sure, you can always taste and add more. 

Step Thirteen

Leave the filling to one side while you prepare the pastry. 

Step Fourteen

Roll out the pastry into two squares on a lightly floured surface. 

One should be big enough to fill the bottom and sides of the tin with a little hanging over, and the other should be able to comfortably cover the top. 

Step Fifteen

Preheat the oven to 180 degrees C (fan-assisted). 

Step Sixteen

Grease your baking tin or pie dish with butter or margarine, taking care to get right into the corners. 

Step Seventeen

Place the larger pastry square into the tin and press into the bottom and sides gently, leaving a little hanging over the edges. If there are any tears, just rip a bit off and patch it up. Pastry is more forgiving than we think. 

Step Eighteen 

Stir the pie filling and carefully spoon it into the tin, filling the pastry as much as possible. 

Step Nineteen

Cover with the other square of pastry. 

Step Twenty

Trim away any excess with a sharp knife.

Step Twenty-One

Press the ends together by firmly crimping around the edges of the tin, pressing the two layers of pastry together securely. You might find this easier to do with damp fingers. 

Step Twenty-Two

Use a pastry brush to brush the egg liberally on the top of the pie. 

Some ready-rolled pastry is pre-brushed, so check the packet. 

Step Twenty-Three

Use a knife to stab two holes into the middle of the pastry. I just stab two slits. 

Step Twenty-Four

Place into the oven and bake for 30 minutes until golden brown. 

Step Twenty-Five

Remove from the oven and rest for a few minutes before serving. This helps the sauce thicken, and the pie holds its shape when cut and removed from the tin. 

Serving Suggestions

Your leftover lamb, mint and potato pie has meat, potatoes, vegetables and pastry. 

It’s got everything you need for a family dinner. I tend to serve with some peas or other green veggies.

Variations

There are a few things that you can do differently when you make leftover lamb, mint and potato pie. 

Change the Quantities

If you have more than 300g of lamb, you might want to use fewer potatoes or carrots to avoid overfilling your pie.

Use Puff Pastry

I prefer a leftover lamb pie with shortcrust pastry, so that’s what I use. Puff is fine, too. 

Use Homemade Pastry

I never make pastry. I don’t have the time or inclination when store-bought is fine. You can, though, of course.

Increase the Mint

I recommend tasting and adding more mint to suit your tastes. 

Skip the Wine

If you prefer not to cook with wine, skip it and go straight to the stock. Add a little at a time, stirring in well before adding more to ensure your flour doesn’t clump together. 

Make a Minted Lamb Pie with Fresh Lamb

You can use fresh meat if you want to make this pie but don’t have any leftover lamb. 

Buy diced lamb, brown it in the cooking pan, and remove before following this recipe as it is. 

Leftovers

This pie is made with leftover roast lamb, so I don’t recommend reheating leftovers for another day. The more you reheat meat, the greater the risks, so I try to just reheat it once.

Storage 

The leftover lamb for this pie can be stored in a sealed tub in the fridge for up to two days. I try to eat it the day after and wouldn’t save it for longer than two days.
