How to Make Slow Cooker Chicken Barley Soup
Step 1: Prep the Vegetables
Start this soul-warming journey by prepping your veggies. Peel and dice the onion, peel and chop the carrots, and slice the celery. You don’t have to be too fussy—rustic chopping works perfectly for Slow Cooker Chicken Barley Soup. The long, gentle cook will soften everything just enough to be irresistibly tender.
Step 2: Season the Chicken
Place your chicken thighs on a chopping board and sprinkle with salt and black pepper. Flip and season the other side too. This extra attention ensures every bite of chicken is deliciously flavorful as it simmers in the soup.
Step 3: Layer the Ingredients
Sprinkle the diced onion into the bottom of your slow cooker, followed by the carrots and celery. Place the seasoned chicken thighs right on top. Layering like this infuses every bite with maximum savory goodness and ensures the chicken cooks to tender perfection.
Step 4: Add the Liquids and Aromatics
Pour in the chicken stock, letting it gently cascade over the layers. Sprinkle dried thyme across the top for an early infusion of herby flavor. The stock and thyme mingle to create a deeply satisfying soup base.
Step 5: Cook and Finish with Barley & Mushrooms
Set your slow cooker to high for 4 hours or low for 8 hours, cover, and let those flavors meld. About an hour before you’re ready to eat, slice the mushrooms. Open the slow cooker and stir in the mushrooms and barley. Use tongs to remove the tender chicken, chop it into bite-sized pieces, and return it to the soup. Stir everything together, replace the lid, and let it finish for the last hour. This step ensures the barley cooks just right and mushrooms retain their lovely bite.
Step 6: Serve It Up
When the time is up, remove the lid and inhale the delicious steam. Ladle your Slow Cooker Chicken Barley Soup into bowls, garnish generously with chopped parsley, and finish with a few extra grinds of black pepper. Get out the big spoons and dig in—you’ve earned it!

Garnishes
A handful of fresh flat-leaf parsley adds a splash of color and a fresh, herbal lift to each steaming bowl. Don’t skip the extra crack of black pepper—both brighten up the flavors and make the Slow Cooker Chicken Barley Soup truly irresistible.
Side Dishes
Serve this soup with crusty sourdough, warm rolls, or even a classic grilled cheese for dunking. A simple green salad with a sharp vinaigrette is a perfect partner, cutting through the richness and complementing the flavors beautifully.
Creative Ways to Present
Try ladling Slow Cooker Chicken Barley Soup into small mugs for a casual gathering or pour it over a scoop of creamy mashed potatoes for ultra-comfort. You can also top each bowl with a swirl of Greek yogurt or a sprinkle of grated Parmesan for a little extra flair.
Make Ahead and Storage
Storing Leftovers
Let leftover Slow Cooker Chicken Barley Soup cool to room temperature before storing. Transfer to airtight containers and pop them in the refrigerator—your soup will keep fresh and delicious for about 3–4 days. The flavors will deepen, and the soup may become even tastier!
Freezing
This soup freezes beautifully. Spoon into freezer-safe containers or bags, leaving a little space for any expansion. Freeze for up to 3 months. Thaw overnight in the fridge (barley will keep its great texture) before reheating.
Reheating
Reheat Slow Cooker Chicken Barley Soup gently on the stove over medium-low heat, stirring occasionally until warmed through. If it’s looking extra thick, just add a splash of water or broth to reach your desired consistency. The microwave works in a pinch as well—just be sure to cover your bowl to keep in all that fragrant steam.
FAQs
Can I use chicken breasts instead of thighs?
Absolutely! While chicken thighs offer a juicier, richer flavor, chicken breasts will also work well and make the soup a bit leaner. Just be mindful not to overcook them so they stay tender.
Do I need to cook the barley before adding?
No need! The barley goes straight into the slow cooker raw one hour before the end. It absorbs flavor and cooks just right this way.
What other veggies work well in this soup?
Swap or add whatever hearty veggies you have on hand. Parsnips, turnips, chopped spinach, or even a handful of peas can all be stirred in for color and variety.
Can I make Slow Cooker Chicken Barley Soup vegetarian?
Yes, simply omit the chicken and use vegetable broth. Boost the protein by adding a can of drained chickpeas or white beans in the last hour of cooking.
Will the barley make the soup too thick?
Barley will plump up and thicken the broth as it cooks, which gives Slow Cooker Chicken Barley Soup its wonderful heartiness. If it gets thicker than you like, just stir in a bit more broth before serving.
