Ingredients to Make Leftover Roast Beef Stew

• Potatoes – Boil them in beef broth for extra flavor; Yukon Gold or red potatoes hold their shape well.
• Beef broth – Use low- or no-sodium to control the salt in the stew.
• Butter – Salted is fine; adds richness to the gravy. If you cook with unsalted butter, you’ll need to adjust the seasoning before serving.
• Celery – Finely diced so it cooks evenly and melds into the stew.
• Onion – Yellow onions work well; they add sweetness when sautéed.
• Mushrooms – I’ve tested this recipe with both white and cremini mushrooms. Both work, but if you like a more assertive mushroom flavor, then go for the cremini, aka baby bellas.
• Garlic – Fresh garlic only; skip jarlic to maintain bright, aromatic flavor.
• All-purpose flour – Helps thicken the stew; mix with a bit of butter or broth first to avoid lumps.
• Baby carrots – Or peel and slice large carrots; add at the right time so they stay tender, not mushy.
• Leftover roast beef – Any tender cut works; trim visible fat and cut into bite-sized chunks. I have tested this recipe with leftover rib roast, strip roast, and sirloin roast. My favorite was the rib roast, but all will work just don’t overcook the beef.
• Montreal steak spice – Adds savory depth; adjust to taste.
• Bay leaves – Remove before serving; they add subtle aromatic flavor without overpowering.

How To make This Easy Beef Stew Recipe

For a full list of ingredients and instructions, please scroll down to the recipe card at the end of this page.

Peel the potatoes, or leave the skins on if they are thin and unblemished, then cut them into bite sized pieces. Simmer them in the beef broth with 1/2 teaspoon salt until they are fork tender.

Meanwhile, sauté the diced onion and celery in the butter or oil until soft, about 5 minutes. Add the garlic and cook for another minute.

Add the mushrooms and cook until they release 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 cook over medium heat until thickened.

Add the carrots and bay leaves and simmer for about 10 minutes or until the carrots are fork tender. Add the potatoes and leftover beef, then season with about 1/2 teaspoon Montreal steak seasoning.

Adjust if needed, heat everything through, and serve.

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.
