1. My Mom’s Old-Fashioned Vegetable Beef Soup ( Yield: 6 Serving )

Ingredients

• 1 pot roast (about 2 pounds)
• 2 russet potatoes, chopped
• 1 bag frozen seasoning blend (or just chopped onions)
• 1 bag frozen peas
• 1 bag frozen green beans
• 1 bag frozen corn
• 4 large carrots, chopped
• 1 (32 oz) container beef broth
• 2 (10.75 oz) cans tomato soup
• 1 can filled with water
• Salt and pepper, to taste

Instructions

Step 1: Season and slow-cook the roast.

Begin by generously seasoning the pot roast with salt and pepper on all sides. Place the roast into your slow cooker and cook on LOW for 6–8 hours or HIGH for 3–4 hours, depending on your schedule.

Slow cooking allows the beef fibers to break down gradually, resulting in meat that is fork-tender and easy to shred. You don’t need to add liquid to the slow cooker unless desired—the roast will release enough juices as it cooks.

Step 2: Shred the cooked beef.

Once the roast is cooked, carefully remove it from the slow cooker and place it onto a cutting board or large bowl. Use two forks to shred the beef into bite-sized pieces. Discard any excess fat. Set the shredded beef aside while preparing the soup base.

Step 3: Start the soup in a large pot.

In a large soup pot or Dutch oven, pour in the entire container of beef broth. Add the two cans of tomato soup along with one can of water (using the empty tomato soup can to measure). Stir well to combine the liquids and create a rich tomato-beef base.

Step 4: Add the fresh and frozen vegetables.

Next, add the chopped potatoes, frozen seasoning blend (or chopped onions), chopped carrots, peas, green beans, and corn. Frozen vegetables work wonderfully in this recipe—they’re convenient, nutritious, and help keep the texture consistent throughout the soup.

Step 5: Add shredded beef and simmer.

Stir in the shredded pot roast. Season with additional salt and pepper to taste. Bring the pot to a gentle boil over medium-high heat, then reduce the heat to low and let the soup simmer for 30–45 minutes. This allows the potatoes and carrots to soften while the flavors meld together beautifully.

Step 6: Adjust seasoning and serve.

Before serving, taste the broth and adjust seasoning if needed. Serve hot with crusty bread, crackers, or a sprinkle of fresh herbs if desired. This hearty soup stores well in the refrigerator and tastes even better the next day as the flavors continue to deepen.

2. Tips for Perfect Old-Fashioned Vegetable Beef Soup

Use leftover pot roast for convenience.

If you already have leftover pot roast from a previous meal, this soup is the perfect way to repurpose it. Simply shred the leftover meat and skip the slow-cooker step.

Don’t skip the slow-cooker method for fresh roasts.

Cooking the pot roast slowly is the key to achieving tender, flavorful meat that blends seamlessly into the soup. Rushing this step can leave the beef tough and chewy.

Balance the vegetables.

Using frozen vegetables ensures you get consistent texture, but you can mix in fresh veggies too. Just remember fresh carrots and potatoes take longer to cook, so add them early.

Add more broth for a thinner soup.

If you prefer your soup more brothy, simply add extra beef broth or water as it simmers.

Avoid overcooking the vegetables.

Once the potatoes are tender, remove the soup from heat. Overcooking can cause vegetables—especially peas—to become mushy.

Let it rest before serving.

Allowing the soup to rest for a few minutes after simmering helps the flavors settle and enhances the overall taste.

3. Frequently Asked Questions

Can I make this soup in a slow cooker entirely?

Yes. After shredding the roast, you can add all remaining ingredients back into the slow cooker and cook on LOW for 4 hours. However, a stovetop simmer gives better texture control for the vegetables.

Can I substitute ground beef for pot roast?

You can. Brown 1½–2 pounds of ground beef in a skillet, drain excess fat, and proceed with the recipe. The flavor will differ, but it still makes a delicious vegetable beef soup.

Can I freeze this soup?

Absolutely. Vegetable beef soup freezes very well. Cool completely, place into airtight containers, and freeze for up to 3 months. Thaw in the refrigerator before reheating.

Can I add pasta or rice to this soup?

Yes, but cook them separately and add just before serving. Adding them directly to the pot causes them to swell and absorb too much liquid over time.

How can I thicken the soup?

If you prefer a thicker consistency, simmer the soup uncovered for a longer time, or mash a few of the cooked potatoes and stir them into the pot.

Is this recipe gluten-free?

All listed ingredients are naturally gluten-free, but make sure to check the labels on tomato soup and broth, as some brands may contain additives with gluten.
