I love pie. It’s a big favourite in our house. 

We love ready-made pies warmed up with chips and peas, but nothing beats a homemade pie with tender beef, tasty sauce and delicious pastry. 

This leftover roast beef pie is absolutely filled with meat, veg and potatoes, so it’s perfect for leftovers even if you don’t have a huge amount of leftover beef. 

Monday Pie is a Great Way to Use Up Leftover Roast Beef

Mondays are tough. It’s so hard to get going again after the weekend, especially in winter when it’s cold, grey and depressing. 

A Monday night pie is a fantastic way to enjoy your leftovers, but it’s also warming and filling – the best comfort food!

Ingredients for Leftover Roast Beef Pie

Margarine – To grease your tin.

Ready to Roll Shortcrust Pastry

Egg – To brush the pastry before baking so that you get a golden-brown crust.

Cooking Spray – Cooking oil like olive oil or vegetable oil is fine, too.

Leftover Roast Beef – Starting with a good quality roasting joint is always good.

Plain Flour

Salt and Pepper

Red Onion

Beef Stock

Henderson’s Relish – This isn’t essential, but it’s a nice addition. Use Worcestershire Sauce if that’s what you’ve got. 

Beer – Something dark, like Guinness.

Potatoes

Carrots – I’ve just added carrots, but you could also add or replace the carrots with mushrooms if you’d like a leftover roast beef and mushroom pie. 

Tomato Puree

Dried Thyme

Can You Use Leftover Roast Potatoes and Leftover Vegetables?

Yes! 

I use fresh, parboiled potatoes in my leftover beef pie recipe, so they stay fairly firm. 

If you do add leftover potatoes, I’d just chop them up and add them to the pie mix in the pastry instead of warming them first so that they hold their shape and don’t go too soft. 

You can also add any leftover vegetables in the same way. Things like carrots are best because they are firm. Broccoli might go a little mushy. 

Making Beef Pie without Beer

I add beer to my pie with leftover beef. It’s tasty, it thickens well, and it’s easy to cook with. 

If you’d prefer, you can add extra stock instead. 

Leftover Beef Pie with Puff Pastry

I make leftover beef pie with shortcrust pastry because that’s what I like best. 

But using ready-to-roll means that you can make leftover beef pie puff pastry instead if you want. Just follow the instructions on the pastry pack and make the filling as it is. 

Making This Pie with Fresh Beef

This pie recipe is the perfect way to use up leftover roast beef, but you can absolutely make it with fresh diced beef, too. 

Just toss your beef in salt and pepper and a little flour, brown and then remove from the pan. Follow the rest of this recipe as it is. 

How to Make Leftover Roast Beef Pie

Using ready-to-roll pastry means that the pie part is actually really easy. 

All the flavour comes from the filling.

The good news is, that’s just a case of simmering it to thicken the sauce and to make sure your leftover beef is incredibly tender. 

You can get the full instructions in the recipe card at the bottom of this post and some tips below. 

Thickening The Pie Mix

I add flour to my diced leftover beef and simmer it for about an hour, which gives the stock and beef gravy plenty of time to thicken up. 

This is essential. If your pie mix is too thin or watery, it will soak into the pastry, and you’ll have a soggy bottom. 

If, after an hour, you feel like your mixture is still too thin, there are a few options to thicken it further:

• Simmer for longer.
• Add a tablespoon or two of gravy granules, and simmer for 15 minutes more (you can add more if needed).
• Scoop some liquid out.

You can do a combination of all of these things if you need to, and you will find that your mixture thickens further as it cools down before you add it to the pastry. 

What Kind of Tin Should You Bake Leftover Beef and Potato Pie in?

I bake my pie in a fairly deep 8-inch square cake tin.

Lightly greased, this is non-stick, so it’s easy to get the pie out. And I like a nice deep pie, so it’s perfect. My pie mixture fills it beautifully, with no leftovers. 

You can use different tins or baking dishes as long as they are heatproof and non-stick, but I find this size is perfect for this amount of pie mix and a 500g pack of ready-to-roll pastry. 

Making Pastry

My husband makes pastry, and you can find his recipe included in my leftover lamb pie. 

Personally, I prefer to use ready-to-roll. It’s easy, tastes great, you can get supermarkets’ own, so it’s cheap, and it saves lots of time and fuss. 

You can, of course, make your own instead if you’d like to. 

What to Serve with Beef and Potato Pie

There are potatoes in the pie, so it’s already fantastically filling. I just serve it with mushy peas, but any vegetables are fine. 

You can also serve it with extra gravy, but it’s not essential.
