Method
 

Step 1: Optional – Brown the Beef
  1. If you want deeper flavor, heat a skillet over medium-high heat and brown the beef cubes for 3–4 minutes. This step is optional but helps build richness and color.
Step 2: Load the Slow Cooker
  1. Place the beef—browned or raw—into the slow cooker. Add the carrots, celery, onion, garlic, mushrooms (optional), and potatoes (optional).
Step 3: Add Barley and Spices
  1. Pour the dry pearl barley over the top. Add the thyme, oregano, paprika, salt, and pepper.
Step 4: Add the Broth
  1. Pour in all 6 cups of beef broth. Gently stir to combine, but do not overmix.
Step 5: Add the Bay Leaf
  1. Place the bay leaf on top. It will release its flavor slowly as the soup simmers.
Step 6: Slow Cook
  1. Cook on:
  2. LOW: 7–8 hours
  3. HIGH: 4–5 hours
  4. You'll know it's done when:
  5. The beef is extremely tender
  6. The barley is soft and chewy
  7. The vegetables are fully cooked
Step 7: Finish and Taste
  1. Remove the bay leaf and stir in the fresh parsley. Taste the broth and adjust salt or pepper as desired.
Step 8: Serve Hot
  1. Use a ladle to serve the soup into bowls. Pair with warm bread, biscuits, or a simple salad for a complete meal.
