Ingredients You'll Need

Start with 1¼ lb (570 g) boneless skinless chicken thighs. Thighs stay succulent during the long cook; if you insist on breast, reduce the time by 90 minutes and add them only for the last hour so they don’t turn stringy. Look for pale-pink flesh with minimal odor—if it smells like anything other than nothing, pass.

You’ll need 3 medium beets, about 1 lb (450 g) untrimmed. I prefer the candy-stripe or golden varieties because they won’t turn your cutting board into a crime scene, but everyday red beets work if you handle them carefully. Choose firm, smooth globes the size of tennis balls; anything larger tends to be woody. Pro tip: if the greens are attached and look perky, the beet is fresh. Sauté those greens tomorrow with garlic and olive oil—zero waste.

1 large leek adds gentle allium sweetness without the bite of onion. Split it lengthwise, fan the layers under cold water, and let the grit fall away. No leek? Two fat shallots or one yellow onion will pinch-hit.

2 medium carrots give natural sweetness and echo the color story. Look for carrots that still have their tops; the greens should be bright, not slimy.

2 ribs celery contribute aromatic backbone. Save the leaves—they’re packed with minerals and make a pretty last-minute sprinkle.

4 cloves garlic, smashed. Smashing releases allicin, the compound that makes garlic good for your heart and slightly less good for your breath.

4 cups (960 ml) low-sodium chicken bone broth. I make mine in the Instant Pot from rotisserie carcasses, but a quality boxed brand like Kettle & Fire or Pacific works. Regular broth is fine; bone broth just amps the protein and body.

1 cup (240 ml) beet kvass or water. Beet kvass is a fermented tonic that adds subtle tang and probiotics; water keeps things neutral. If you’re a kombucha fan, you’ll love kvass.

2 bay leaves, 1 tsp dried thyme, ½ tsp black pepper, 1 tsp kosher salt. These are the baseline aromatics; we’ll brighten everything at the end.

Finishing players: 1 Tbsp apple-cider vinegar to lock in magenta, zest and juice of ½ lemon for lift, and a handful of fresh dill or parsley for spring-on-a-spoon vibes. For garnish, I like a swirl of plain Greek yogurt or a crumble of goat cheese, plus toasted pumpkin seeds for crunch.

How to Make Slow Cooker Chicken and Beet Soup for Healthy Eaters

Prep the vegetables

Scrub the beets and trim the tops and tails, but leave the skin on—it slips off effortlessly after cooking and keeps the color from bleeding. Slice the leek into half-moons, dice the carrots and celery into ¼-inch pieces, and smash the garlic with the flat of a knife. Keep the beet separate from the other vegetables to prevent Technicolor cross-contamination.

Layer the slow cooker

Place the chicken thighs on the bottom of a 6-quart slow cooker—this protects them from over-cooking and keeps the meat submerged. Scatter the leek, carrot, celery, and garlic on top. Nestle the whole beets among the vegetables like ruby Easter eggs. Tuck in the bay leaves and sprinkle the thyme, salt, and pepper evenly.

Add liquid and acid

Pour in the bone broth and beet kvass (or water). The solids should be just barely covered; add an extra splash if needed. Drizzle the apple-cider vinegar over everything—this small step is the difference between muddy purple and jewel-tone magenta.

Cook low and slow

Cover and cook on LOW for 7–8 hours or HIGH for 4 hours. Resist the urge to lift the lid; every peek drops the temperature by 10 °F and adds 15 minutes to the total time. The soup is ready when the beets are fork-tender and the chicken shreds effortlessly.

Remove and shred

Using tongs, transfer the beets to a plate to cool slightly. Fish out the chicken thighs and place them on a cutting board. Slip the beet skins off with your fingers or a paring knife—they’ll come off like silk stockings. Shred the chicken with two forks; it should yield easily into bite-size strands.

Dice and return

Dice the peeled beets into ½-inch cubes for pleasant texture. Return the shredded chicken and diced beets to the slow cooker. The broth will immediately turn a show-stopping fuchsia.

Brighten and season

Stir in the lemon zest, lemon juice, and fresh dill. Taste and adjust salt; depending on your broth, you may need another ½ teaspoon. Let the soup heat through for 5 minutes on HIGH so the flavors marry.

Serve with flair

Ladle into warm bowls. Top each portion with a dollop of Greek yogurt, a scatter of toasted pumpkin seeds, and an extra pinch of fresh herbs. Serve with crusty whole-grain bread or a simple green salad dressed with lemon vinaigrette.

Expert Tips

Keep it pink

A teaspoon of vinegar preserves the beet’s color, but avoid baking soda; it turns the broth brown and murky.

Overnight upgrade

Make the soup on Sunday, refrigerate overnight, and reheat gently; the flavors deepen and the broth clarifies.

Zero-waste greens

Sauté the beet greens with olive oil and garlic for a quick side, or blend them into the soup for extra minerals.

Freeze smart

Freeze in silicone muffin trays for single-serve pucks; transfer to a bag and you’ll have instant lunch for up to 3 months.

Double-batch bonus

The recipe doubles beautifully in an 8-quart cooker; leftovers morph into pasta sauce or the base for a hearty grain bowl.

Quick-release trick

If you’re short on time, cook on HIGH for 4 hours, then switch to “keep warm” for 30 minutes for a flavor boost.

Variations to Try

Spicy Moroccan: Add 1 tsp ground cumin, ½ tsp cinnamon, and a pinch of harissa. Swap dill for cilantro and finish with a squeeze of orange juice.
Creamy velvet: Purée half the finished soup with an immersion blender and stir in ½ cup coconut milk for a dairy-free cream version.
Lentil boost: Add ½ cup rinsed red lentils during the last 2 hours for extra fiber and a silky texture.
Spring green: Replace beets with 2 cups diced zucchini and 1 cup peas; add fresh mint instead of dill.
Smoky paprika: Stir 1 tsp smoked paprika and a bay leaf into the broth for a subtle campfire note that pairs with the sweetness of beets.

Storage Tips

Refrigerator: Cool the soup completely, transfer to airtight containers, and refrigerate up to 5 days. The color may deepen, but the flavor improves. Reheat gently over medium-low heat; microwaving can turn the chicken rubbery.

Freezer: Ladle cooled soup into quart-size freezer bags, lay flat to freeze, then stack like books for up to 3 months. Thaw overnight in the fridge or submerge the sealed bag in cold water for 30 minutes. Stir in a squeeze of fresh lemon after reheating to wake up the flavors.

Make-ahead: Chop all vegetables and store in a zip-top bag with a paper towel to absorb moisture for up to 3 days. You can also sear the chicken quickly in a skillet for extra flavor, though it isn’t necessary for tenderness in the slow cooker.

Frequently Asked Questions

Absolutely—this recipe cooks the beets whole in the slow cooker, so there’s no need to pre-roast. The long, moist heat tenderizes them perfectly and makes the skins slide right off.

Beets are naturally higher in carbs, so a serving contains roughly 18 g net carbs. If you’re strict keto, substitute radishes or turnips for a similar texture with fewer carbs.

Fresh basil, tarragon, or even a handful of baby spinach blended in at the end all work beautifully. Start with ¼ cup and adjust to taste.

Yes. Simmer the chicken and whole beets in a Dutch oven with 5 cups broth for 45 minutes, add vegetables, and cook another 15 minutes until tender. Proceed with shredding and seasoning as written.

Temper the yogurt by whisking it with a few spoonfuls of hot broth before swirling it into the bowl. Full-fat Greek yogurt is more stable than non-fat.

Yes, double every ingredient but keep the salt at 1½ tsp to start; you can always add more later. Cooking time remains the same because the volume still fits within the cooker’s efficient thermal mass.
