Ingredients
  

For the Beef
  • 1.5 lb beef chuck roast trimmed and cut into 1-inch cubes
  • 1 tbsp olive oil
  • 1 tsp salt divided
  • 0.5 tsp black pepper freshly ground
For the Soup
  • 1 large yellow onion diced (about 1.5 cups)
  • 3 medium carrots peeled and sliced 1/2-inch thick
  • 2 ribs celery sliced 1/2-inch thick
  • 3 cloves garlic minced
  • 1 tsp dried thyme
  • 1 bay leaf
  • 8 cups beef broth low sodium
  • 0.75 cup pearled barley not quick-cooking
  • 2 tbsp tomato paste
  • 1 tbsp Worcestershire sauce
  • 0.25 cup fresh parsley chopped, for garnish

Equipment

  • 6-quart Slow Cooker
  • Large skillet

Method
 

Prep
  1. Pat beef cubes dry with paper towels - this is crucial for browning. Season with half the salt and all the pepper. Heat olive oil in a large skillet over medium-high heat until shimmering. Working in batches to avoid crowding, sear beef until deeply browned on all sides, about 6-8 minutes total per batch. Transfer to slow cooker.
  2. Reduce heat to medium. Add onion, carrots, and celery to the same skillet. Cook, scraping up browned bits, until vegetables soften and onion turns translucent at the edges, about 5 minutes. Add garlic and thyme; cook 1 minute until fragrant. Stir in tomato paste and cook 1 minute more. Transfer everything to the slow cooker.
Build the soup
  1. Add bay leaf, beef broth, barley, Worcestershire sauce, and remaining salt to the slow cooker. Stir well to combine, making sure barley is submerged in liquid.
  2. Cover and cook on LOW for 8 hours or HIGH for 4-5 hours, until beef is fork-tender and barley is chewy but cooked through. The soup should be thick; if too thick, stir in hot water 1/4 cup at a time. Remove bay leaf and taste for seasoning.
  3. Ladle into bowls and garnish with fresh parsley. Serve with crusty bread for soaking up every last drop.

Notes

Don't skip browning the beef - it builds the deep, savory foundation that makes this soup special. Pearled barley (not quick-cooking) holds its texture during long cooking; quick-cooking varieties will turn mushy. This soup thickens considerably as it cools; when reheating, thin with water or additional broth to your desired consistency.
