Ingredients

  • 4 cups leftover roast beef trimmed and cubed
  • 1 pound small potatoes diced
  • 2 cups low sodium beef broth
  • 2 tablespoons butter
  • 1 onion diced
  • 3 stalks celery diced
  • 2 cloves garlic minced
  • 8 ounces mushrooms quartered or sliced
  • 1/4 cup all-purpose flour
  • 8 ounces baby carrots
  • 2 bay leaves
  • 1/2 teaspoon Montreal Steak Seasoning

Instructions

  • Peel the potatoes (or leave the skins on if they are thin and unblemished) and cut the potatoes into bite-sized pieces. Simmer them in the beef broth with 1/2 teaspoon salt, until they are fork-tender. About 5-8 minutes.
  • Meanwhile, saute the diced onion and celery in the butter or oil until soft, over medium heat, about 5 minutes. Add the garlic and cook for an additional minute.
  • Add the mushrooms to the vegetables and cook until they give off their liquid.
  • Add the flour to the vegetables and mix well. Add the cooking liquid from the potatoes, stir well to dissolve the flour, and heat over medium heat to thicken.
  • Add the carrots and bay leaves and simmer for about 10 minutes or until the carrots are fork-tender. Add the potatoes and the beef and season with about a half teaspoon of Montreal Steak seasoning to start (you can always add a bit more.) Heat it through and serve!

Notes

Chef Jenn's Tips

  • Trim the fatty or gristly bits from the leftover roast beef and cut it into bite-sized cubes.
  • Don't worry if your gravy seems really thick. The vegetables will give off some liquid while finishing cooking and will thin out the sauce. If it's still too thick, and a smidge more beef broth or even water to thin it out.
  • Conversely, if it's too thin, make a bit of a slurry (1 tbsp all-purpose flour plus 2 tablespoons cold water mixed well) and add that to the gravy and simmer it to thicken some more.
  • No Montreal Steak Seasoning? Just season the Leftover Roast Beef Stew with salt and freshly ground pepper.
