This soup is seriously next-level good.

What really drew me to this slow cooker chicken soup recipe was how it uses a rainbow of veggies and an herb garden’s worth of flavors. Unlike many recipes, it’s brimming with onions, carrots, and parsnips, plus a fresh mix of herbs that boost every spoonful.

The original version was a stovetop recipe, but I switched it up for the slow cooker to keep things simple. Plus, I adore the idea of chicken soup slowly cooking all day, filling the house with that amazing aroma you can’t wait to come home to. Like most slow cooker meals, you just toss everything in, walk away, and come back to magic. Adding farro near the end seals the deal and keeps texture perfect.

It’s that easy, crazy healthy, and even better tasting than you’d expect.

The only way I think this soup could get any better is adding a slice of crusty bread on the side—you definitely don’t want to skip that.

One Sunday, I let this slow cooker chicken soup cook all day while I was filming some videos. My son Kai was fighting a pesky cold and said chicken soup was the only thing he wanted. So I popped everything in the slow cooker and by the time we wrapped filming, the soup was ready. We both agreed it’s the perfect chicken soup, with the fresh cilantro on top adding a beautiful punch.

I saved the leftovers for the next day’s lunch and honestly, the soup tasted even better after sitting overnight. Quick tip: if you’re meal prepping or saving leftovers, either scoop out the farro before storing or make it separately and add it to your bowl when serving. Hot broth alone will warm it up nicely. Leaving farro in the soup while storing means it’ll absorb a lot of the broth and get mushy.

Also, here’s a fun touch—not pictured—but I ended up topping my soup with stove-popped popcorn. It sounds quirky, but it’s something my mom always did and honestly, popcorn on chicken soup is a game changer. You have to try it.

When the temperature drops and you want your home to smell like a warm hug the second you walk in, this slow cooker chicken soup should be your go-to. It’s a timeless, brothy chicken soup loaded with veggies and brightened with fresh herbs and lemon, delivering comforting flavors that really sink in after slow cooking all day.

Expect effortless prep: dump everything in your crockpot in the morning, forget about it, and by dinner you’ll have a rich broth with tender chicken and soft vegetables. I like adding farro near the end so it stays perfectly chewy and doesn’t soak up all that delicious broth. Finish each bowl with a squeeze of lemon and fresh herbs—oh, and crusty bread or popcorn on the side is totally encouraged!

Below, you’ll find the full slow cooker instructions plus stovetop and Instant Pot options, timing tips (low 5–6 hours or high 4–5 hours), and my favorite hints about storing leftovers and freezing. Just a quick tip: be sure to remove the farro before storing so your soup keeps that great broth texture.

It’s a breeze to prep, cooks behind the scenes all day with barely any effort, feeds a crowd, and tastes even better the next day. Serve it with crusty bread, a classic spinach salad, or even popcorn (trust me here) for a meal that feels like a warm hug in a bowl.

Expert Tips for Success

• Use bone-in chicken if you can — it makes the broth richer and more flavorful. Just remove the bones when shredding for easier eating; if you want a refresher on the technique, try this easy pulled chicken method.
• Be sure to clean your leeks thoroughly—they’re great flavor but can trap dirt between layers. Slice them, then rinse in a bowl of cold water before adding them to the slow cooker.
• Don’t add the farro at the start. Adding it about 45 minutes before serving keeps it chewy and stops it from soaking up all the broth and getting mushy.
• If you want to save leftovers, take out the farro before storing or cook it separately. That way your soup stays broth-y and delicious overnight.
• Always add fresh herbs and lemon juice at the very end. This brightens the soup and brings back fresh flavors, especially after reheating.
• If the soup tastes a little flat just before serving, a quick squeeze of lemon and pinch of salt lifts everything perfectly.

Mix-Ins and Substitutions

• Swap grains easily: use pasta, brown rice, white rice, or quinoa instead of farro. Just mind the cooking times—add pasta later or cook grains beforehand.
• Switch up the protein: boneless skinless thighs work well, or use shredded rotisserie chicken added in the last 20 minutes to warm through.
• Add greens if you like: stir in chopped kale, spinach, or Swiss chard during the last 5–10 minutes for extra color and nutrients.
• Boost the flavor and immunity with a thumb-sized piece of fresh grated ginger and a pinch of turmeric added along with the stock.
• Want it vegetarian? Use vegetable broth and swap chicken for cannellini beans or extra mushrooms for a hearty, meatless version—or try a creamy vegan asparagus soup (dairy free) as an alternative.

Storing, Freezing, and Reheating

• Refrigerate: Let the soup cool completely, then transfer to airtight containers. Store for up to 3–4 days. For best texture, remove the farro (or any pasta/rice) before storing so the broth stays light.
• Freeze: Once cooled, freeze in freezer-safe containers for up to 3 months. For the best results, freeze shredded chicken and broth separately from cooked farro—a method that also works for other soups like Creamy Roasted Pumpkin Soup. Thaw in the fridge overnight before reheating.
• Reheat: Warm gently on the stove over medium-low heat, stirring occasionally, or microwave in a covered bowl. Add a splash of stock or water if the soup thickened too much. Finish with fresh lemon juice and herbs before serving.
• Make-ahead idea: You can prep the soup base (broth plus veggies) in advance and refrigerate for 1–2 days. Add chicken and cook as directed when ready to eat, or just assemble and slow cook all at once (or try a creamy make-ahead option like Crockpot Tuscan Chicken).

Common Questions

• Q: Can I use boneless chicken instead of bone-in?

  A: Absolutely! Boneless chicken works fine, and it cooks a bit faster too. But bone-in pieces give the broth extra depth of flavor. Just watch your cooking times so you don’t overcook.

• Q: Is it okay to use frozen chicken in the slow cooker?

  A: It’s best to thaw chicken first for evenly cooked and safe results. If you have to use frozen, add extra cooking time and make sure it reaches 165°F inside. Thawing in the fridge ahead is always safer.

• Q: My farro soaked up all the broth—how can I avoid that?

  A: The trick is adding farro late in the cooking—about 45 minutes before you want to eat—or cooking it separately and adding to individual bowls. That keeps your soup from turning too thick.

• Q: How do I make this gluten-free?

  A: Swap farro for rice, quinoa, or gluten-free pasta. Make sure your chicken stock is gluten-free too, and you’re good to go.

• Q: Can I thicken the soup?

  A: Yes! To thicken, simmer uncovered to reduce the broth, or blend some cooked veggies and stir them back in (see how pureed vegetables build creamy body in this Easy Pumpkin Soup). A cornstarch slurry also works for a quick boost.

• Q: How do I season the soup?

  A: Start with the pinch of salt in the recipe, then taste toward the end and adjust. Adding lemon juice and fresh herbs right before serving really brightens all those cozy flavors.
