What do you do with leftover roast beef and potatoes?

If you’re looking for some ideas, you’ve come to the right place.

From sandwiches to hashes, I’ve got plenty of recipes that will help you make the most of your leftovers.

So, put on your thinking cap and get ready to cook up something delicious.

Make a sandwich

Making a sandwich from your leftover roast beef and potatoes is a quick and easy way to get rid of them.

Just slap some horseradish mayo on a roll or baguette, layer with the meat and potatoes, maybe some cheese if you have it, then broil until the bread is toasted.

Dinner’s ready.

Make a salad

To make a salad from your leftovers, you need to do some prep work.

Toss out any wilted veggies and cook anything else that might be able to stand up to dressing (i.e., not potatoes).

Then chop the roast beef into cubes or slices and break up your taters.

Put it all in a bowl with finely chopped lettuce (or whatever greens you have on hand), some chopped bell pepper, onion, or shallots for crunch.

Dress liberally with any vinaigrette you have in the fridge and serve with fresh bread or crackers.

Make a hash

Hash is another great way to use your leftover roast beef and potatoes.

Hash comes together pretty quickly, so if you’ve only got a little bit left you can still prepare it.

Just brown the beef and potatoes with some onions, then add an egg or two, maybe some cheese if that’s your thing, and serve.

It only takes a few minutes and tastes great hot or cold.

Make a soup

In order to make a soup from your leftover roast beef and potatoes, you’ll need to make some stock.

That’s one of the tolls for using leftovers in soup; making the stock is a pain in the butt.

But if you have about an hour or so it isn’t that bad, just start early.

Once your stock is nice and flavorful, add whatever veggies are on-hand (potatoes, carrots, celery) and some fresh herbs if you have them.

Let the flavors infuse as the veggies cook (you can do this by either simmering or roasting), then add your leftover roast beef and potatoes cubes.

Season with salt and pepper to taste, then serve.

Make a quesadilla

Quesadilla is another great way to use up your leftover roast beef and potatoes.

They’re easy to assemble, take about five minutes to cook per quesadilla (so you can make several at once), and are scrumptious.

Just slice some baguette or ciabatta thinly, brush with oil or butter, then bake until they’re crispy.

Next, lay down some slices of cheese (go for a melting cheese like Monterey Jack or Muenster if you can find it), add your cubed beef and potatoes, plus any other veggies you might like (corn, scallions, tomatoes), then top with another slice of cheese.

Put in a skillet until the bread is crispy and the cheese is melted.

Finally, remove from the heat and transfer to a plate, then slice and serve.

Make a frittata

Frittatas are another classic way to use up all those leftovers you’ve got in your fridge or freezer.

Just whisk together some eggs (preferably with an equal amount of milk), then add your leftover roast beef and potatoes.

Season with salt, pepper, cheese (optional), or any other herbs or spices you like.

If you have some veggies that need to be used up, toss them in too.

Bake the frittata at 350 degrees for about 30-40 minutes until it’s puffed and golden brown, then serve.

Make a pizza

The possibilities of what you can do with your leftover roast beef and potatoes are endless; there’s no end to the things you can make using these ingredients as the base.

One such recipe is pizza, which is pretty darn easy to make from scratch, so I’ll share my favorite dough recipe: it’s pretty basic, but I’ve found that the simpler the dough the better it comes out.

To make my pizza dough (yields 2 thin-crust pizzas), you’ll need:

3 cups flour 1 tsp yeast 2 tsp salt 4 tbsp olive oil 1 cup warm water

Mix together all ingredients until a loose dough forms; knead/stir until a tight dough forms.

Divide into two balls, then let it sit for about half an hour to rise.

Once the dough has risen, roll out onto a floured surface and shape as desired.

The only rule with pizza is that there are no rules, so use whatever you want.

I always make sure to have some veggies (onions, mushrooms, peppers) and cheese (mozzarella is my go-to).

Bake at 450 degrees for about 10 minutes until the crust is golden brown and crispy.

Make some curry

Curry is another great option if you’re looking for a creative way to use up your leftover roast beef and potatoes.

Just dice them up and add them to a pot; we’re going to make a curry, so the combinations of veggies and spices are almost endless.

Just keep in mind that you want it on the spicy side (since you can’t really taste any individual flavors), so just go big with the chili powder.

If you have some diced tomatoes or tomato sauce lying around, adding that to the pot is another way to add flavor, as well as some yogurt if you’d like it creamy.

Cook until your veggies are tender and enjoy with rice or naan.

Make beef stew

To make beef stew, just follow the same steps for making curry.

Just chop up all of your leftovers (potatoes, beef, veggies), add some stock and just about any spices you have on hand (cumin or smoked paprika would be a good place to start), and simmer until it’s thickened.

Serve with potatoes, mashed if you’ve got them.

Make a burrito bowl

Beef and potatoes make a pretty good filling for a burrito bowl.

Start by cooking up some rice, then add in your beef and potatoes along with any veggies you have on hand (corn, beans, bell peppers).

Top with salsa or hot sauce if you can handle the heat.

If you want this to be a bigger meal that can stand alone, feel free to pack it all up in a tortilla.

Make fried rice

Fried rice is yet another great use for your leftover roast beef and potatoes; if you have some cooked brown rice, this recipe couldn’t potentially be easier.

Chop up your veggies (scallions, carrots) and fry them in butter in a pan; add your leftover beef and potatoes, along with any soy sauce or fish sauce you like.

Cook for about 10 minutes until everything is well-heated, then toss in the rice.

Fry the rice (on medium-high heat) for about 5 minutes until it’s heated through, then serve.


There are so many possibilities for dishes that you can make with leftover roast beef and potatoes.

Whether you want to stick with simple recipes or get a little more creative, these ingredients provide the perfect foundation.

From pizza to curry to fried rice, I’ve shared some of our favorite recipes that will help you use up your leftovers in no time.
