First Step: Prepare Ingredients Start by chopping the onion finely, mincing the garlic, slicing the carrots, and dicing the celery and bell pepper. Measure out the pearl barley and beef broth so everything is ready to add during cooking.

Second Step: Brown the Beef Heat oil in a large, heavy pot over medium-high heat. If using cubed beef chuck, pat dry and season with salt and pepper. Sear the beef in batches until browned on all sides (about 5-7 minutes). Remove the beef and set aside. If using ground beef, brown it with onions and drain excess fat.

Third Step: Sauté Vegetables In the same pot, add a little more oil if needed. Sauté onions and garlic until fragrant and translucent, about 3-4 minutes. Add carrots, celery, and green bell pepper, and cook for 3-5 minutes until they start to soften.

Fourth Step: Deglaze the Pot If using red wine, pour it into the pot to deglaze, scraping up the browned bits from the bottom. Allow the wine to reduce by half to concentrate flavors.

Fifth Step: Combine Ingredients and Simmer Return the browned beef to the pot. Add beef broth, diced tomatoes with juices, Worcestershire sauce, thyme, bay leaf, and pearl barley. Bring the soup to a boil, then reduce heat to low, cover partially, and simmer for 40 to 60 minutes. The barley and beef should be tender, and the flavors well blended.

Sixth Step: Final Adjustments Remove the bay leaf. Taste and season with salt and black pepper as needed. If the soup thickens too much on cooling, add extra broth or water to reach your desired consistency. Stir in fresh parsley just before serving to add brightness.

Final Step: Serve and Enjoy Ladle the beef barley soup into bowls and serve hot, accompanied by crusty bread or a green salad for a complete meal. This soup also works well for batch cooking and freezing in individual portions.
