Sneak Preview: Leftover Steak Soup combines the flavor of a leftover rib-eye or tenderloin steak with the umami of mushrooms. Adding tangy sour cream as the final touch creates a tasty gravy for dipping homemade French Bread or Ciabatta.

Are you like me and wondering what to do with leftover steak?

Our Christmas is over, the decorations are boxed and stashed back into the attic, but my fridge is still reeling from excess food, specifically leftover rib roast. It was delicious but too big for one meal.

That’s why this recipe was born.

Recycling a Christmas Rib Roast

Prepare this soup quickly with leftover meat. Use any leftover or pre-cooked steak you have on hand. Even a leftover roast would be delicious.

Herbs, spices, and a splash of red wine make the soup more interesting. Although I specify fresh herbs, you can substitute dried herbs if you have them on hand.


Ingredients and substitutions:

  • Bacon: Pork bacon, turkey bacon, or small pieces of fatty ham can be used. Use bacon bits from a bag (like Costco sells) for convenience.
  • Onion: Yellow or white onions both work. Or use frozen onions from the freezer section in the supermarket.
  • Mushrooms: Fresh white button mushrooms are the least expensive and my first choice. I prefer to quarter them for soup. Canned mushrooms are a last resort.
  • Beef Broth or Beef Stock: I rarely have this on hand. If you are the same, make broth with 5 cups of water and one tablespoon of beef bouillon concentrate.
  • Kitchen Bouquet: Kitchen Bouquet adds umami flavor. Substitute Worcestershire sauce if you can’t find it.
  • Soy Sauce: Soy sauce is another source of flavor (and salt).
  • Red Wine: You only need a splash–or leave it out if you prefer.
  • Bay Leaf: Bay leaves add so much flavor. These are always in my spice drawer. If you don’t have them, it’s OK to skip them. Don’t forget to remove the leaf before serving the soup.
  • Cornstarch: Substitute flour for cornstarch 1:1. If you need gluten-free, substitute arrowroot flour 1:1.
  • Sour Cream: Sour cream is the secret to the stroganoff flavors in this soup, in addition to the mushrooms. Substitute light sour cream if you’re watching the calories.
  • Leftover steak: This recipe is designed for leftover steak that has been cooked.

FAQs :

What can I serve with steak soup?

Hopefully, you’ve got some Sourdough Bread, Garlic Sticks, or White Crusty Bread in the house. Toast a slice for dipping in the saucy sour-cream-flavored goodness.

You could go in a different direction by dishing up mashed cauliflower or potatoes, noodles, or rice in each soup bowl first, then topping with this stroganoff-like soup.

Can I freeze this soup?

I don’t recommend freezing soup with sour cream as it tends to separate during the thawing and reheating process.

How can I use this recipe to rescue tough leftover steak?

If the steak is a tougher cut of meat like chuck steak or round steak, add it to the broth (in step three) and let it cook until it’s tender.

Can I use raw steak in this recipe?

I recommend you use my recipe for Easy Beef and Mushroom Soup in a Slow Cooker for raw beef if you have raw meat that needs to cook for an extended period of time like chuck or round beef.

Parting Thoughts: Be careful not to overcook tender steak like prime rib. Warm it gently by adding it at the end just before serving.

    Delicious blend of flavours! I had no sour cream so used a little cream cheese thinned out with milk, which worked well. As the recipe suggests, add the beef right at the end to avoid making it too chewy /tough. Really good soup/stew! Will make again.

    1. Hi Jennoe,
      Thank you so much for coming back to leave a comment. Glad you liked it. I never thought of using cream cheese, but why not? Creme fraiche would also be good instead of sour cream.
