Leftover Roast Beef Cottage Pie is one of the best ways to use up Sunday lunch leftovers. A classic, comforting dinner, with deliciously tender chunks of leftover meat in a rich, tasty gravy.
It’s filling, it’s got meat, veg and potatoes in one pot, and it’s all topped with cheese! Perfect!
Even better, cottage pie is so simple. There are no fancy ingredients, you can make substitutions easily, and there’s no complicated method.

The only thing that ever makes a cottage pie better in my opinion is if you make it with chunks of beef, instead of mince.
Chunks of slow-cooked beef take on all the flavour of the rich gravy and fall apart in your mouth. The texture is just so much better than with mince.
This is why making Cottage Pie with Leftover Roast Beef is always a fantastic idea!
How Should You Cut Leftover Roast Beef to Make Cottage Pie?
When it comes to the leftover roast beef, if you like your cottage pie with mince, you might want to shred the beef, or at least chop it as small as you can.
However, I really like chunks of meat. I chop mine into fairly small cubes, around 1cm. I just love the texture of slightly chunkier meat.
It wouldn’t hurt if you wanted them bigger, especially if you’ve got quite a lot of leftover meat.
Ingredients for Leftover Roast Beef Cottage Pie
When I make Leftovers Cottage Pie, I like to keep things really simple, just like when I make Traditional Cottage Pie.
As well as the chunks of beef, I add onions, carrots, and peas for some veggies. Then, the gravy is beef stock, red wine, tomato puree, Henderson’s Relish, and mixed herbs.
The red wine is optional, you can just add more stock instead, but I think it gives it a really yummy rich flavour.
You can also add extra water if the stock and wine don’t cover the other ingredients.
The mashed potato topping is just fluffy white potatoes, like King Edwards, mashed with butter, milk and a pinch of salt and pepper. I then top it all with mature cheddar.
Cheddar cheese is ideal for Leftover Roast Beef Cottage Pie Recipe because it melts really well, but you can use mild instead if you prefer.
What Do You Bake a Cottage Pie in?
I bake my Cottage Pie Made from Leftover Roast Beef in a cast-iron dish (affiliate link).
Because it’s both flame-proof and oven-proof, I can simmer the cottage pie middle on the hob, before topping with mash and cheese and baking in the oven, without having to change pans.
If you don’t have anything suitable for both the hob and the oven, simmer your filling in a large frying pan (af link), before tipping into an ovenproof dish (af link) to bake once topped with mash and cheese.
