What’s in this Steak Soup Recipe?
This is my mom’s famous steak soup recipe, adapted from and inspired by the famous Plaza III steakhouse in Kansas City. It’s a hearty mixture of veggies, sirloin, and lots of seasonings!
- Vegetable Oil: Helps the vegetables cook without burning.
- Mirepoix: A combination of carrots, celery, and onion that adds rich flavor to the base of this soup.
- Unsalted Butter: Adds richness to the vegetables and combines with the flour to create a roux.
- Garlic: Adds an earthy flavor and a pungent aroma.
- Ground Chuck: A premium version of ground beef that adds luscious fat and flavor to this soup.
- Sirloin: I like to use top sirloin; trim any excess fat and cut it into 2-inch pieces.
- All-Purpose Flour: Combines with the unsalted butter to create a roux that helps thicken the soup.
- Unsalted Beef Broth: Forms the base of this soup.
- Water: Helps add volume to the soup without adding extra sodium.
- Red Wine: Adds a rich depth of flavor to this soup.
- Ac’cent Seasoning: Also known as MSG, this seasoning enhances the flavors of this soup. It’s totally optional, though!
- Beef Stock Concentrate: Adds rich beefy flavor to the soup.
- Frozen Mixed Vegetables: An easy way to add extra nutrients to this soup. I like a mix with sweet peas, corn, carrots, and green beans.
- Petite Diced Tomatoes: Add a touch of acidity and sweetness.
- Black Pepper: Helps the flavors of this soup pop.
Pro Tip: If you prefer, you can swap out the red wine for more beef broth.

I love to use a combination of ground chuck and sirloin steak. Chuck is incredibly flavorful, and sirloin is super tender!
Yes! I like to get a nice bit of browning on my steak before adding it to the soup to add extra flavor.
If the sirloin is tough after cooking, you likely need to cook it for a bit longer to help it break down and become tender.
The Ac’cent seasoning, which is MSG, is perfectly safe to add to this soup. MSG is a great flavor enhancer when added in small amounts. However, you can leave it out if you prefer.
