Easy Leftover Roast Beef Stroganoff

It's a great idea to make enough Roast Beef for leftovers and this is one of my favourite ways to make a whole new meal.  

  • 3-4 cups slivered leftover roast beef
  • 2 tablespoons oil
  • 1 large onion
  • about 15 large button mushrooms
  • 2 tablespoons flour
  • 2 cups beef or mushroom broth
  • 1/3 cup red wine (optional)
  • 1/4 cup fresh or freeze dried chopped parsley
  • 1 teaspoon dried thyme
  • 1/2 teaspoon garlic powder
  • a few dashes cayenne pepper
  • 1 cup sour cream
  • salt and pepper to taste
  • wide or medium hot buttered noodles
  1. In a large saucepan, saute onion and mushrooms in oil over medium heat, stirring occasionally until veggies begin to caramelize.
  2. Add flour and stir to combine for a minute and then add mushroom or beef broth and red wine, stirring to create a sauce.  
  3. Add leftover roast beef and seasonings and simmer a few minutes to blend flavours.
  4. Add sour cream and season with salt and pepper to taste. Heat through.
  5.  Add a bit more broth if necessary to thin the sauce and bring to a simmer. 
  6. Serve over hot buttered noodles. 


  1. How delicious! This is perhaps one of my favourite dishes of all time :)

  2. This looks pretty good and there seems to be enough to feed a small army. Suddenly, I'm hungry. Thanks for leaving a comment on Monday Mural. It is amazing how many you see when you start looking.

  3. Oh that sure looks good. Great idea to make extra roast beef just for this delicious "left over" meal! I've made stroganoff using ground beef but must try it tis way sometime.

  4. How do you sliver your roast beef? Just curious. And of course it looks scrumptious, and a tad above plain old hamburger stroganoff.

    1. Melodie, I find it really easy to slice when it is cold. I use a very sharp paring knife and it works great!

  5. An amazing dish. You would never think you were eating leftover roast beef. Made the recipe as is with the exception of adding 1 1/2 TBSP butter to the oil. I did not add salt or pepper because it didn't need it. Portabella mushrooms were used. Looks like it could easily serve 6 people. Pretty easy recipe. I wasn't too sure about the cayenne, but I think it really makes the dish.

  6. When do you add the cooked beef

    1. Thank you for pointing out that omission. I've added it to the instructions now.
