When the mushrooms hit the pot, they soften and release liquid before any browning starts. That wet stage can make it seem like the soup is already underway, but letting the liquid cook off gives the mushrooms a deeper, savory taste that carries through every bowl.
This chicken mushroom barley soup with fresh herbs makes six generous servings, with tender chicken thighs and pearl barley in a broth that turns pleasantly hearty as it simmers. I like that the barley gives the soup body without needing cream or a flour-thickened base.
The chicken goes in after the barley has had a head start, so it can cook gently while the grains finish softening. Fresh parsley stirred in at the end keeps the long-simmered broth tasting bright, and the finished soup is full of tender vegetables, chewy barley, and shredded chicken.
Kitchen Note
I let the soup rest off the heat for the full five minutes after the parsley goes in. The barley settles into the broth, and the soup is easier to ladle without rushing it straight from a bubbling pot.

Why the mushrooms need to brown before the broth goes in
Mushrooms give off a surprising amount of liquid as they heat. Before that moisture evaporates, they’re essentially simmering in their own juices, so they stay soft and pale instead of developing the deeper flavor that makes this broth taste rounded. The change is easy to spot: the pot starts wet, then the liquid cooks away and the mushrooms begin to brown.
That little stretch of cooking is worth giving them. If broth goes in while the mushrooms are still releasing liquid, they won’t have the same chance to brown, and the soup will miss some of its savory depth. Keep the heat at medium and stir occasionally; the mushrooms don’t need constant attention, just enough time for their moisture to cook off. Add the garlic only after they’ve started browning, since minced garlic can scorch if it sits in the pot too long.
What the barley, chicken, and fresh herbs each bring to the pot
- Pearl barley — It gives the broth a tender, pleasantly chewy texture and thickens it as it cooks. Rinse it before it goes into the pot, as called for here. Pearl barley is the right choice for this timing; quick-cooking barley softens much faster. If you need a gluten-free bowl, see the rice adaptation below rather than swapping grains one-for-one.
- Boneless, skinless chicken thighs — Thighs stay succulent through a gentle simmer and shred easily once cooked. A store-brand pack is fine; choose pieces that are similar in size so they cook at a similar pace. Chicken breast works as a leaner alternative, though the finished shreds won’t be quite as rich.
- Cremini mushrooms — Their earthy flavor holds up against chicken broth and barley. Fresh, firm mushrooms are best, but there’s no need to seek out a specialty variety. Slice them evenly so they cook at roughly the same rate; shiitake caps are a good swap when you want a deeper, more pronounced mushroom taste.
- Fresh thyme — Thyme can simmer with the broth without losing its savory, woodsy character. If fresh thyme isn’t available, use one teaspoon of dried thyme in its place and stir it in with the broth ingredients.
- Fresh parsley — Parsley goes in after the chicken is shredded, so its clean, green flavor stays noticeable instead of fading during the simmer. Chopped chives can stand in as a finishing herb; they’ll bring a mild onion note rather than parsley’s grassy freshness.
- Low-sodium chicken broth — It lets the chicken and mushrooms come through while leaving room to season the soup with kosher salt. A standard store-brand broth works well; the low-sodium choice is useful here because the broth reduces slightly as the soup cooks.
Build the soup in stages so the barley and chicken finish together
Soften the vegetables before browning the mushrooms
Heat the olive oil in a 6-quart Dutch oven or soup pot over medium heat. Add the chopped onion, carrots, and celery, then cook for 5 minutes, stirring occasionally, until they begin to soften. Add the sliced mushrooms and cook for 7 to 9 minutes, stirring now and then, until they release their liquid and begin to brown. Stir in the minced garlic and cook for 30 seconds, just until fragrant.
Start the barley in the seasoned broth
Add the chicken broth, rinsed pearl barley, chopped fresh thyme, kosher salt, black pepper, and bay leaf. Bring the pot to a boil over high heat, then reduce the heat to maintain a gentle simmer. Partially cover the pot and cook for 15 minutes. Keep the simmer gentle rather than letting the broth boil hard.
Simmer the thighs until the grain is tender
Add the chicken thighs and bring the soup back to a gentle simmer. Cook partially covered for 20 to 25 minutes, until the barley is tender and the thickest part of the chicken reaches 165°F. Check a thicker thigh rather than relying only on the outside color. If the chicken reaches temperature before the barley is tender, take it out and use the troubleshooting note in the FAQ.
Shred the chicken and finish with parsley
Transfer the cooked thighs to a cutting board and remove the bay leaf from the pot. Shred the chicken with two forks, then return it to the soup and stir in the chopped parsley. Take the pot off the heat and let it rest for 5 minutes before serving. The barley will continue to absorb broth as the soup sits, so the texture will be hearty rather than thin.
Easy ways to adapt this chicken, mushroom, and barley soup
Use shiitake mushrooms for a deeper, earthier bowl
Replace the cremini mushrooms with 8 ounces of sliced shiitake caps. Their flavor is more intense and savory, so the soup will taste earthier; keep the same browning step and cooking time.
Swap in chicken breasts for a leaner soup
Use 1 1/2 pounds of boneless, skinless chicken breasts in place of the thighs. Cook them in the soup until the thickest part reaches 165°F, then shred as usual. The meat will be leaner and a little less succulent, so check it rather than leaving it simmering after it’s cooked through.
Make a gluten-free bowl with rice
Use low-sodium chicken broth labeled gluten-free, leave out the barley, and spoon cooked plain rice into each bowl before ladling in the soup. Adding rice to individual servings keeps it from soaking up the broth in the pot, though rice won’t have barley’s chewy texture.
Storage and Reheating
- Refrigerator: Cool and refrigerate within 2 hours, then store in an airtight container for 3 to 4 days. The barley will absorb more broth and soften as it sits.
- Freezer: Freeze in airtight, portion-size containers for up to 3 months. The barley may be softer after thawing, but the soup freezes well; thaw it in the refrigerator.
- Reheating: Warm gently on the stovetop, stirring in a little extra chicken broth if the barley has thickened the soup. Heat leftovers to 165°F, and avoid a hard boil, which can make the chicken tougher and the barley too soft.
