Creating Beef Barley Soup is straightforward if you follow these easy steps:

1. Prepare Ingredients: Start by cutting the beef into 1-inch cubes. Dice the onion, slice the carrots and celery, and mince the garlic.
2. Brown the Beef: In a large pot, heat the olive oil over medium-high heat. Add the beef cubes and brown on all sides, about 5-7 minutes.
3. Cook Onions and Vegetables: Add the diced onion, carrots, celery, and minced garlic to the pot. Cook until vegetables soften, about 3-4 minutes.
4. Add Broth: Pour in the beef broth and stir to combine.
5. Stir in Barley and Seasonings: Add the pearl barley, Worcestershire sauce, bay leaf, thyme, and season with salt and pepper.
6. Bring to a Boil: Increase the heat and bring the soup to a boil.
7. Simmer: Once boiling, reduce heat to low and simmer uncovered for about 1 hour and 30 minutes, or until the barley and beef are tender.
8. Adjust Seasoning: Taste the soup and adjust the seasoning, adding more salt or pepper as needed.
9. Remove Bay Leaf: Before serving, take out the bay leaf.
10. Serve: Ladle the soup into bowls and garnish with fresh parsley if desired.
