Why You’ll Love This Beef & Barley Soup
Made with just 5 main ingredients
Rich, savory broth with tender beef
Naturally thick and satisfying
Perfect for cold weather and meal prep
Freezer-friendly and great for leftovers
Ingredients You’ll Need
1½ pounds beef stew meat, cut into bite-sized pieces
1 cup pearl barley, rinsed
1 medium onion, chopped
8 cups beef broth (or enough to cover ingredients by about 1 inch)
2 cups frozen mixed vegetables (carrots, peas, corn, green beans)
Optional (not counted as ingredients):
Salt and black pepper, to taste
Step-by-Step Instructions
Step 1: Add the Beef
Place the beef stew meat in the bottom of a 5- to 6-quart slow cooker, spreading it out in an even layer. This helps the meat cook evenly and become tender.
Step 2: Layer the Onion and Barley
Sprinkle the chopped onion over the beef, then add the rinsed pearl barley on top. Rinsing the barley removes excess starch and helps keep the broth from becoming gummy.
Step 3: Add the Broth
Pour in the beef broth, adding enough to cover all the ingredients by about 1 inch. Give everything a gentle stir so the barley settles into the liquid.
Step 4: Slow Cook
Cover with the lid and cook:
On LOW: 7–8 hours
On HIGH: 4–5 hours
The soup is ready when the beef is fork-tender and the barley is soft and fully plumped.
Step 5: Add the Vegetables
About 30–45 minutes before serving, stir in the frozen mixed vegetables. Break up any frozen clumps, cover again, and continue cooking until the vegetables are heated through and tender.
Step 6: Adjust Seasoning and Texture
Taste the soup and season with salt and black pepper as desired.
If the soup is too thick, stir in a little more hot broth or water.
If it’s too thin, leave the lid off for the last 15–20 minutes to let some steam escape.
Step 7: Serve
Ladle the soup into warm bowls, making sure each serving has plenty of beef, barley, vegetables, and rich broth. Serve hot.
Variations & Helpful Tips
Use Fresh Vegetables
Swap frozen vegetables for diced carrots, celery, onions, or even chopped cabbage if you have them on hand.
Extra-Rich Flavor
For deeper, old-fashioned flavor, brown the beef in a skillet with a little oil before adding it to the slow cooker. This extra step adds a rich, “Sunday supper” taste.
Tomato Version
Stir in a 14.5-ounce can of diced tomatoes (with juices) along with the broth for a slightly tangy, tomato-based soup.
Thicker, Stew-Like Texture
Reduce the broth by 1–2 cups or add an extra ¼ cup of barley for a heartier bowl.
Lighter Option
Use half beef broth and half water, and trim visible fat from the beef before cooking.
Flavor Boosts (Optional Extras)
If you don’t mind stepping beyond five ingredients, add:
1 bay leaf
A pinch of dried thyme
1 clove minced garlic
Storage & Reheating
Leftovers keep well in the refrigerator for 3–4 days. The soup will thicken as the barley absorbs more broth, so add a splash of water or broth when reheating to reach your desired consistency.
