Ingredients For leftover Beef Stroganoff

When I make my leftover roast beef stroganoff recipe, I use:

Butter – Margarine is ok, but butter will have a much better flavour. You could also use olive oil, but I prefer butter.

Red Onion – Brown/yellow is ok too, but I prefer red. 

Garlic – or Garlic puree. 


Dijon Mustard

Smoked Paprika

Lemon Juice – Fresh or bottled is fine. 

Beef Stock

Leftover Roast Beef – Ideally about 400g, but use whatever you’ve got. 

Salt and Pepper

Soured Cream

Parsley – Fresh is best, but I often use dried.

You’ll Also Need

I recommend a sharp knife and chopping board to chop your beef and vegetables, and I cook my stroganoff with leftover beef in a large non-stick frying pan. A cast-iron Dutch Oven would be good, too. Anything that’s flameproof and non-stick. 

You’ll also need a spatula and a saucepan to cook your sides.

Top Tips

This leftover roast beef stroganoff recipe is super simple, so there are not too many tips.

  • You don’t need to cook, or sear the beef first, because it’s a stroganoff with cooked beef. It’ll warm as it simmers in the sauce.
  • I recommend butter instead of margarine. 
  • Use full-fat dairy, which is less likely to separate.
  • If, after 20 minutes, your sauce is too watery, simmer for a little longer to thicken it up.

Serving Suggestions

I usually serve my leftover roast beef stroganoff with pasta. Something like tagliatelle is good, but tubes are nice too because all the sauce gets inside, so there’s stroganoff sauce with every bite. 

Other options include rice, potatoes and egg noodles. I’ve never tried it, but I suspect beef stroganoff from leftover roast would be amazing on a baked potato. Because I think everything is great on a baked potato!

You could also serve with bread or garlic bread to mop up the creamy stroganoff sauce

There are a few variations that you can make to this leftover roast beef stroganoff recipe. 

First, the soured cream. I prefer leftover roast beef stroganoff with sour cream, but I know some recipes call for cream or crème fraiche. Some people even make leftover roast beef stroganoff with cream of mushroom soup. 

Next, the vegetables. I just add mushrooms, but you can add some peppers, too, if you want to. I usually use close cup or button mushrooms; chestnut would be great, too. See my mushroom stroganoff recipe for some options. 


I don’t recommend saving leftovers because the leftover roast beef has already been cooked twice, and every time you reheat meat, the risks increase. Try to eat your beef stroganoff with leftover roast on the same day as you cook it.

Before making stroganoff, make sure your leftover roast beef is stored in a clean, sealed or covered tub in the fridge (between 1-5 degrees C) and that you only keep it for a day or two

Don’t save beef if it wasn’t in date when you cooked it or if it’s been left out on the side for too long (just leave it out to cool, doing so quickly by removing it from the cooking pan) and throw it away if it smells, looks or feels off. Trust your instincts.

I try to cook my leftover roast beef from Sunday on Monday. 


What is Stroganoff Sauce Made of?

Typically, stroganoff sauce is made from soured cream and stock or beef broth and then flavoured with mustard and sometimes paprika. I love to add plenty of mushrooms, too.

Can You Make Leftover Roast Beef Stroganoff Without Soured Cream?

Yes, you can use cream or crème fraiche. Some recipes even use cream of mushroom soup or cream cheese, but I haven’t tried these. I don’t recommend yoghurt, which can separate, but if you want to try it, use full-fat. 

Can You Freeze Leftover Beef Stroganoff?

Because this recipe uses leftover Roast beef, I wouldn’t advise freezing or keeping it at all. 

Can You Make This Recipe with Fresh Beef?

Yes, just brown the beef first. 

What Can I Do with Tough Leftover Beef?

I always think tough beef is better in something slow-cooked, like a stew or casserole. See this post for more ways to use tough leftover roast beef.

What Do You Serve Beef Stroganoff With?

Beef stroganoff with pasta is lovely. Rice, potatoes or even bread work, too. 

Is Beef Bourguignon the Same as Beef Stroganoff?

No beef bourguignon is more of a stew.

Why is My Beef Stroganoff Chewy?

If your leftover beef was overcooked or tough, it will probably stay tough in a stroganoff. Cutting into thinner strips might help.

  1. It looks delicious! We rarely have leftovers after having roast beef but this looks delicious so I’ll just have to buy a bigger joint of beef next time so I can have a go at something like this.

  2. Stroganoff is one of my favourite winter warmers, love it! I often do a version in the slow cooker, and love to come home to the beautiful smell of it cooking away. This one looks perfect! Thank you for sharing #CookBlogShare

  3. I made this using some frozen Cooked pork and Beef slices I found in my freezer. I used Full fat Philadelphia cheese rather than Sour cream as that was all I had available during the Covid lockdown And served it with white rice. This meal tasted amazing-better than any Stroganoff I had ever bought in the shops and it was so Quick and easy to make. I was very impressed and will make it again

    • Sounds lovely Linda, I’m a big fan of using what you’ve got, and I must say we’re using some funny ingredients at the moment too!! Hope you are safe and well, I’m so glad you enjoyed the recipe. Take care.

  4. My husband gave the ultimate compliment….”.I like this better than the 1st time we had the roast beef” ! Thank you for sharing. It was so easy and tasty!!

  5. I was looking at another recipe and saw yours. I had leftover cooked beef and cooked pork. Followed your recipe … love the idea of red onions and used Crimini mushrooms, garlic and added red bell pepper for color and added Worcestershire sauce and love the Dijon mustard and paprika and little sour cream. Mix in cooked rotelle pasta. Delicious.. Thank you for sharing

  6. Lush. Was worried the beef would do tough but it was just as tender as the first time round. My fussy eater loved it though he avoided the mushrooms! Swapped sour cream for Greek yogurt

  7. As a veggie with a “meatie” hubby I’m always looking for recipes that could be easily adapted to work for both of us to save cooking 2 entirely separate meals AND using up left-over meat from his roast (I never buy a tiny joint!) made this a winner! Prepared the sauce then split across 2 pans for the 20 minute simmer, 1 with the beef and 1 with extra mushrooms for me, mountain of rice, job done, absolutely yummy with very little effort or skill required – my kind of meal! Thank you

  8. Our house recipe for stroganoff was using ground beef, but this recipe will take over as #1! It was absolutely delicious. We don’t really enjoy leftover roast beef, my hubby doesn’t like gravy so it limits what you can do with it. The flavours were spot on with this. I didn’t have a smoky paprika(on my grocery list) so shook in a bit of mesquite seasoning. I used a regular onion, will try the red next time. We think the beef was more tender and tasty in this recipe than first made! Glad I found this, thank you.

  9. Made it. Followed the recipe. Delicious. Don’t worry about the Smoked Paprika. It’s smokiness is extremely subtle after cooking and is worth the taste medley.
