Ingredients You'll Need

Each component here pulls its weight, creating layers of sweet, savory, and bright. Read through the notes so you can shop confidently and know exactly what to look for at your market.

Protein

2 lb (900 g) boneless, skinless chicken thighs – Thighs stay juicy after hours of gentle heat; if you only have breasts, nestle them on top so they cook more slowly and don’t dry out.

Produce

3 medium carrots, sliced ½-inch thick – Look for brightly colored tops; avoid cracks or limp spots.
2 parsnips, peeled and cut into ½-inch coins – Choose small-to-medium parsnips; larger ones have woody cores.
1 large sweet potato, peeled and ¾-inch dice – Japanese sweet potatoes are drier and fluffier; garnet yams give a deeper orange hue.
1 small celery root (celeriac), peeled and ¾-inch dice (optional but heavenly) – Mild celery flavor with the texture of a creamy potato.
1 large yellow onion, diced – I like a sweet onion for balance; red onion will tint the broth purple.
4 cloves garlic, smashed – Smash instead of mincing so the pieces are easy to fish out if anyone objects to “specks.”
1 bunch lacinato (dinosaur) kale, stems removed and chopped – Curly kale works; just tear into bite-size bits and massage for 30 seconds to soften.
Zest of 1 large orange + juice of half – Use a microplane to avoid bitter white pith.

Pantry & Seasonings

4 cups low-sodium chicken broth – Homemade if you’re fancy; boxed if you’re human.
1 cup dry white wine or additional broth – Wine adds acidity; broth keeps it weeknight-easy.
2 Tbsp tomato paste – Deepens color and umami without turning the stew into tomato soup.
2 tsp kosher salt + ½ tsp black pepper – Start conservative; you can adjust at the end.
1 tsp dried thyme + 1 bay leaf – Classic aromatics; fresh thyme sprigs (3-4) work too.
1 Tbsp honey or maple syrup – Balances citrus and tomato; omit if you prefer savory-only.
2 Tbsp olive oil – For sautéing the tomato paste; adds silkiness.

How to Make Slow Cooker Chicken and Kale Stew with Citrus and Root Vegetables

Prep the aromatics: In a small skillet, heat olive oil over medium. Add tomato paste and cook, stirring, until it turns from bright red to brick red and smells slightly caramelized—about 3 minutes. This step burns off raw metallic notes and blooms the natural sugars. Scrape every last bit into the slow-cooker insert.

Layer the roots: Scatter onion, carrots, parsnips, sweet potato, and celery root (if using) into the insert. Season with half the salt and pepper. Think of this as a vegetable bed that will cradle the chicken and prevent it from sitting directly on the hot bottom.

Nestle the chicken: Pat thighs dry so they brown (yes, even in a moist environment, surface moisture inhibits Maillard reaction). Arrange in a single layer, slightly overlapping is fine. Sprinkle remaining salt, pepper, thyme, and the bay leaf over top.

Deglaze and pour: In the same skillet, warm wine (or 1 cup broth) and scrape up any browned tomato bits. Pour this liquid, plus the remaining broth, around—not over—the chicken to keep the seasoning intact. The liquid should come about ¾ up the sides of the meat.

Low and slow: Cover and cook on LOW for 6 hours or HIGH for 3–3½ hours. Avoid lifting the lid—each peek drops the temperature 10–15 °F and adds roughly 15 minutes to the total time. The stew is ready when the vegetables are fork-tender and chicken shreds effortlessly.

Shred and stir: Transfer chicken to a plate; using two forks, shred into bite-size strands. Discard bay leaf. Return chicken to the pot and fold in kale. The residual heat will wilt the leaves in 3–4 minutes without turning them army-green.

Brighten with citrus: Stir in orange zest, juice, and honey. Taste and adjust salt or more juice if you like tang. The broth should be light, fragrant, and slightly sweet-savory.

Serve smart: Ladle into shallow bowls over a scoop of farro, quinoa, or crusty bread to soak up every drop. Garnish with extra orange peel curls or a drizzle of peppery olive oil for restaurant flair.

Expert Tips

Overnight Flavor Boost

Cook the stew completely, cool, refrigerate overnight, and reheat the next day. The flavors mingle and the broth thickens slightly for a richer spoonful.

Control the Salt

Different broth brands vary wildly in sodium. Start with 1½ tsp salt and add more at the end once ingredients have released their own juices.

Kale Shortcut

Buy pre-washed baby kale and stir it in during the last 2 minutes—it wilts instantly and removes the stem-stripping step.

Thick vs. Brothy

For a thicker stew, whisk 2 Tbsp cornstarch with ¼ cup cold water and stir in at the end; cook on HIGH 10 minutes until glossy.

Citrus Swap

Blood orange, Meyer lemon, or even lime zest each give a different vibe—rotate with the seasons.

Temperature Check

If you own a probe thermometer, chicken is safely done at 165 °F; in a slow cooker it will likely reach 190 °F, perfect for shredding.

Variations to Try

Spicy Moroccan: Add 1 tsp each cumin, coriander, and smoked paprika plus ¼ tsp cayenne. Sub butternut squash for sweet potato and finish with chopped preserved lemon.
Creamy Tuscan: Stir in ½ cup heavy cream and ¼ cup grated Parmesan with the kale. Swap orange for lemon zest and add a handful of sun-dried tomatoes.
Vegetarian Power Bowl: Omit chicken, double the beans. Add two 15-oz cans of chickpeas, rinsed, and use vegetable broth. Cook on LOW 4 hours so flavors meld without chicken juices.
Asian-Inspired: Replace wine with ½ cup low-sodium soy sauce plus 1 Tbsp grated ginger. Finish with lime juice and a drizzle of toasted sesame oil.

Storage Tips

Refrigerator: Cool completely, transfer to airtight containers, and refrigerate up to 4 days. The stew will thicken as the vegetables absorb broth; thin with a splash of water or broth when reheating.

Freezer: Portion into quart-size freezer bags, press out excess air, label, and freeze flat up to 3 months. Thaw overnight in the fridge, then warm gently over medium-low heat to prevent chicken from becoming stringy.

Make-ahead lunch jars: Spoon stew into 2-cup heat-proof jars with tight lids. Keep a container of cooked quinoa or brown rice on the side; combine just before microwaving to keep textures perky.

Frequently Asked Questions

Yes, but add 1 extra hour on LOW. Make sure pieces are separated, not frozen together in a brick, so they cook evenly. Always check the largest thigh reaches 165 °F.

You can skip it, but the stew will taste flatter. Browning takes 3 minutes and creates caramelized flavor compounds that deepen the whole pot.

Lacinato kale needs at least 3–4 minutes in hot broth to soften. If you used curly kale, strip the thick center rib and chop smaller or cook a few minutes longer.

Absolutely. Use a heavy Dutch oven, simmer covered on the lowest burner flame for 1½–2 hours, stirring occasionally, until vegetables are tender and chicken shreds easily.

Stir in an extra ½ cup broth and 1 tsp honey. Simmer 5 minutes. The sweetness will balance sharp acid.

A crusty sourdough or warm naan is perfect. For gluten-free diners, serve over jasmine rice or with cornbread muffins.
