The combination of slow-cooked beef, earthy vegetables, and wholesome grains makes this soup the perfect dish for chilly evenings or meal prep.

With just a few minutes of prep, this soup simmers low and slow, allowing the ingredients to meld beautifully. Serve it with crusty bread, a simple salad, or enjoy it on its own as a complete and nourishing meal.

What You Need for This Recipe

A few staple ingredients come together to make this soup rich, satisfying, and full of deep, comforting flavors.

  • Beef Chuck or Stew Meat – A well-marbled cut that becomes fork-tender as it cooks. The slow cooking process helps break down the fibers, making every bite melt in your mouth.
  • Pearl Barley – A chewy, nutty grain that thickens the soup and makes it extra satisfying. Barley absorbs the broth beautifully while maintaining a slight bite.
  • Carrots, Celery & Onion – A classic combination that adds depth and a natural sweetness to the broth. These vegetables soften over time, creating a rich base for the soup.
  • Garlic & Herbs – A mix of fresh garlic, thyme, and bay leaves enhances the overall flavor. These aromatics slowly infuse into the broth for a well-rounded taste.
  • Beef Broth – Provides a deep, savory backbone to the soup. Use a high-quality broth for the best flavor, or make your own for an even richer result.

How to Make Slow Cooker Beef and Barley Soup

This recipe requires minimal prep, and the slow cooker does the rest of the work.

  • Brown the Beef (Optional but Recommended)
    • Heat a skillet over medium-high heat and add a little oil.
    • Sear the beef chunks for 2-3 minutes on each side until browned.
    • Transfer to the slow cooker. Browning adds extra depth to the flavor, but you can skip this step if you’re short on time.
  • Prepare the Vegetables
    • Dice the onions, carrots, and celery.
    • Mince the garlic and add everything to the slow cooker.
  • Add the Broth & Seasonings
    • Pour in the beef broth, ensuring it covers all ingredients.
    • Add bay leaves, thyme, salt, and black pepper.
    • Stir everything together to evenly distribute the flavors.
  • Cook on Low & Let the Flavors Develop
    • Cover and cook on low for 7-8 hours or high for 4-5 hours until the beef is tender.
    • About 30 minutes before serving, stir in the barley and continue cooking until it softens. This prevents the barley from becoming mushy.
  • Final Touches & Serve
    • Remove the bay leaves and check the seasoning.
    • Stir well and ladle into bowls.
    • Garnish with fresh parsley or a sprinkle of black pepper for extra depth.

Ways to Customize This Soup

This soup is incredibly versatile, and small adjustments can make it fit your preferences.

  • Make It Gluten-Free – Swap barley for brown rice or quinoa for a gluten-free version.
  • Use Different Vegetables – Add mushrooms, potatoes, or bell peppers for extra flavor and texture.
  • Enhance the Broth – A splash of Worcestershire sauce or a bit of red wine deepens the umami notes.
  • Thicken the Soup – Mash some of the cooked vegetables or stir in a cornstarch slurry for a richer consistency.

Why This Recipe Always Works

This soup is designed to be hearty, flavorful, and foolproof—every element contributes to making it a comforting, well-balanced meal.

  • Rich & Savory – The long cooking time allows the beef to become fall-apart tender while the broth intensifies in flavor.
  • Nutrient-Dense – Packed with protein, fiber, and vegetables, making it both satisfying and wholesome.
  • Perfect for Meal Prep – Tastes even better the next day, and leftovers store well for easy reheating.

Equipment

  • Slow Cooker For cooking the soup
  • Large Skillet For browning the beef (optional)
  • Ladle For serving

Ingredients
  

  • 1.5 pounds beef chuck or stew meat cut into bite-sized pieces
  • 1 tablespoon olive oil for browning the beef
  • 1 small onion diced
  • 3 cloves garlic minced
  • 3 medium carrots peeled and sliced
  • 2 ribs celery chopped
  • 6 cups beef broth low sodium preferred
  • 3/4 cup pearled barley rinsed
  • 2 teaspoons Worcestershire sauce for depth of flavor
  • 1 teaspoon dried thyme
  • 2 whole bay leaves
  • 1 teaspoon salt adjust to taste
  • 1/2 teaspoon black pepper adjust to taste
  • 2 tablespoons fresh parsley chopped, for garnish

Instructions
 

  • If browning the beef, heat olive oil in a large skillet over medium-high heat. Sear the beef on all sides until browned, about 3 minutes per side. Transfer to the slow cooker.
  • Add diced onion, minced garlic, carrots, and celery to the slow cooker.
  • Pour in the beef broth, Worcestershire sauce, and add dried thyme, bay leaves, salt, and black pepper. Stir well to combine.
  • Cover and cook on LOW for 7-8 hours or HIGH for 4-5 hours until the beef is tender.
  • About 30 minutes before serving, stir in the rinsed barley. Cover and let cook until barley is tender but not mushy.
  • Remove bay leaves, taste, and adjust seasoning as needed.
  • Ladle into bowls, garnish with fresh parsley, and serve warm.

Notes

  • For extra depth, add a splash of red wine when sautéing the beef.
  • Leftovers store well in the fridge for up to 4 days; the barley will continue to absorb liquid, so add extra broth when reheating.
  • For a thicker soup, mash a few of the cooked vegetables before serving.
