How to Make My Mom’s Old-Fashioned Vegetable Beef Soup

Cook the Beef
Season the pot roast generously with salt and pepper. Place it in your slow cooker with half a can of beef broth. Set it on LOW and let it work its magic for about 10 hours until it’s tender and shreds like a dream.
Sauté the Veggies
In a large pot, heat a splash of oil over medium heat. Toss in the chopped carrots and the frozen seasoning blend (or onions). Sauté until they start softening and smelling irresistible—about 5-7 minutes.

Combine & Simmer
Add the shredded beef, chopped potatoes, frozen peas, green beans, corn, remaining beef broth, tomato soup, water, and a sprinkle of salt and pepper. Give it all a good stir.
Let It Simmer to Perfection
Bring the pot to a gentle boil, then reduce the heat to low. Cover and let it simmer for about 1 hour, stirring now and then. If it thickens up too much, just add a splash of water to loosen it.
Slow Cooker Version
Prefer to keep it hands-off? After shredding the beef, toss everything back into the slow cooker and cook on LOW for another 6-8 hours. Dinner practically makes itself.

Olivia’s Tips for the Perfect Homemade Beef Soup

Flavor Boost: Add a splash of Worcestershire sauce or a pinch of Italian seasoning if you want to zhuzh up the flavor.
Veggie Swap: Don’t have frozen peas or green beans? No stress! Use whatever’s in your freezer stash.
Thicker Broth? If you like your soup extra thick and stew-like, let it simmer uncovered for the last 15 minutes.

Leftover Magic: This soup tastes even better the next day—perfect for lunchbox heroes.

And if your soup looks a little too “rustic” (read: chunky and hearty), that’s the charm of a true old-fashioned soup. Embrace it!

A Family Favorite Story from My Kitchen

This recipe has been a staple in my family for as long as I can remember. My mom used to make this hearty vegetable soup on chilly Sunday afternoons while the rest of us lounged around in fuzzy socks. The smell of simmering beef and veggies would fill the house, and by dinnertime, everyone magically appeared in the kitchen, bowls in hand.

When I became a mom, this recipe became my saving grace for busy school nights and family get-togethers. It’s one of those dishes that gets passed down, not just because it’s delicious, but because it brings everyone to the table, no questions asked. Now, my kids request “Grandma’s beef soup” whenever the weather turns crisp. And honestly? I don’t mind one bit.

What to Serve with Old-Fashioned Vegetable Beef Soup

This soup is a meal on its own, but if you’re like me and believe every good soup deserves a sidekick, here are a few ideas:

A loaf of crusty sourdough bread for dipping.
Classic grilled cheese sandwiches (because melty cheese + soup = happiness).

A simple green salad with vinaigrette to add a fresh crunch.
Cornbread muffins if you’re feeling extra homey.

And don’t forget a cozy blanket and your favorite spot on the couch for ultimate comfort.

How to Store and Reheat Leftovers
