This Leftover Roast Beef Stew is a recipe from the early days of my site that suddenly got popular again recently, and I wondered why. Then I realized that now beef is so much more expensive that when people splurge on a nice beef roast, they’re probably searching for another dinner idea to make with the leftovers! And this recipe is the perfect way to use leftover roast beef to make a tasty stew!

This beef stew recipe also a perfect example of something that’s tasty no matter what kind of diet you’re following, and with all the flavor from green pepper, mushrooms, roasted tomatoes, oregano, and basil, you won’t miss the potatoes or carrots a bit. This is a flexible recipe, and you can adjust amounts and ingredients to what you have hanging out in the fridge.

The one thing I think is essential is the dried herbs that are simmered in the stock, with the addition of some fresh basil or frozen basil at the end. For me it was a good reason to buy one of those basil plants that you see in the grocery store, and so far I am keeping it alive in my window! But even if you don’t have fresh basil this is delicious and I hope you’ll try it if you get some leftover roast beef!

What ingredients do you need?

  • onion
  • green pepper
  • olive oil
  • leftover roast beef or steak
  • canned beef broth (or use homemade beef stock if you have some)
  • canned diced tomatoes
  • dried oregano
  • dried basil
  • mushrooms
  • fresh basil or frozen basil (probably optional, but good)
  • salt and fresh-ground black pepper to taste

What if you don’t have fresh or frozen basil?

If you don’t have fresh basil or frozen basil you can use the chopped basil that’s sold in a tube, but another easy option if you don’t need the recipe to be dairy-free would be to use my favorite purchased basil pesto to add that basil flavor.

What makes this leftover beef stew extra flavorful?

Of course starting with roast beef adds flavor to this Italian beef stew. But the stew is also extra flavorful from the green pepper, tomatoes, mushrooms, dried oregano, and dried basil. And if you finish it off with some fresh basil that makes it even better.

What if you have less than a pound of leftover roast beef?

If you have a whole pound of leftover roast beef, I urge you to use the full amount (or even more). But if you don’t have a full pound of beef cubes you can still make a tasty stew. You could use more green pepper or  more mushrooms, or add zucchini, add red bell pepper, add artichoke hearts, or add another vegetable you enjoy in stew. You could also add some bacon or sausage to the stew.

Use at or least 2 cups diced beef cubes for this recipe if you don't have a full pound of leftover roast beef. You can also use leftover steak.

This recipe is a perfect use for frozen chopped basil. You can also use the chopped basil that's sold in a tube if you prefer or use my favorite purchased basil pesto to add the basil flavor.
