Ingredients You'll Need

Great stew begins with smart shopping. Seek bone-in, skin-on chicken thighs for collagen that naturally thickens the broth; if you’re partial to white meat, add two bone-in breasts but keep at least half the meat thigh-based for richness. For squash, choose a heavy, matte-skinned butternut (indicates full ripeness) and a firm acorn squash with no orange patches—those signal over-maturity. Thyme should be perky and silvery green; if the leaves are black-tipped, the herb is past its prime. Lemon is the surprise star: its zest goes in at the start for essential oils, while the juice is stirred in at the end to keep the flavor bright. Tomato paste in a tube is convenient and less wasteful; look for one with no added sugar. Finally, keep your chicken stock low-sodium so you can reduce and concentrate flavors without over-salting.

How to Make Slow Cooker Chicken and Winter Squash Stew with Lemon and Thyme

Brown the chicken for deeper flavor

Pat the thighs dry and season generously with 1 ½ tsp salt and ½ tsp pepper. Heat olive oil in a skillet over medium-high. Place chicken skin-side down; sear 3 minutes until golden. Flip, cook 2 minutes more. Transfer to slow cooker, skin-side up. The fond left behind equals free flavor—don’t wash the pan yet!

Build the aromatic base

In the same skillet, reduce heat to medium; add onion, carrot, and celery with a pinch of salt. Cook 4 minutes until edges soften. Stir in tomato paste and garlic; cook 2 minutes until brick red and fragrant. Deglaze with ½ cup stock, scraping browned bits. Pour entire mixture over chicken.

Add squash & seasonings

Nestle butternut cubes around chicken; they’ll break down and thicken the stew. Layer acorn half-moons on top so they stay intact. Tuck thyme sprigs and bay leaves between pieces; scatter lemon zest. Sprinkle chili flakes if using. Season with ½ tsp more salt and several grinds of pepper.

Pour liquid, but not too much

Add remaining stock until liquid reaches three-quarters up the ingredients; the squash will exude moisture. Starting with less broth ensures concentrated flavor—you can always thin later. Avoid submerging the chicken skin; it won’t stay crisp but will lend richness.

Low and slow magic

Cover and cook on LOW 7–8 hours or HIGH 4–5 hours, until chicken registers 175 °F (the extra heat helps collagen melt). If you’re home, baste once halfway; if not, no worries—gravity does the work.

Shred and stir

Remove chicken to a plate; discard skin if desired (I save it for crispy chef snacks). Use two forks to shred meat into bite-size chunks; return to pot. Fish out thyme stems and bay leaves. Stir in white beans and juice of half the lemon; taste, then add more lemon or salt.

Finish bright

Let stew bubble 10 minutes on HIGH to marry flavors. Just before serving, sprinkle remaining fresh thyme leaves and a whisper of lemon zest. The broth should be velvety, not watery; if too thick, splash stock or water; if thin, mash a few squash cubes against the side and simmer uncovered.

Serve and savor

Ladle into shallow bowls over toasted sourdough, quinoa, or cauliflower rice. Garnish with extra black pepper, a drizzle of peppery olive oil, or shaved Parmesan for a salty bite. Leftovers taste even better tomorrow—promise.

Expert Tips

Skin-on is non-negotiable

The skin renders fat that coats vegetables and prevents dryness. Remove after cooking for lower fat, but don’t skip the sear.

Zest first, juice later

Zesting a naked lemon is torture; do it while the fruit is whole. Microplane just the yellow layer—white pith equals bitterness.

Layer textures

Butternut breaks down into creamy broth; acorn holds shape. Swap delicata for acorn if you want edible peel and faster prep.

Bean brine bonus

Aquafaba (chickpea liquid) can replace half the stock if you want lighter body and extra protein—just reduce added salt.

Herb swaps

No thyme? Use rosemary, but keep quantity modest—rosemary is stronger. Dried thyme works in a pinch: ½ tsp per fresh sprig.

Crouton crown

Toss cubed stale bread with olive oil and garlic powder; bake at 375 °F for 10 min. Float on stew for restaurant vibe.

Variations to Try

Smoky Paprika & Turkey: Replace chicken with turkey thighs and add 1 tsp smoked paprika plus ½ tsp chipotle powder for a Spanish twist.
Coconut-Ginger: Swap 1 cup stock for full-fat coconut milk; add 1 Tbsp grated fresh ginger and lemongrass stalk for Thai-inspired notes.
Vegetarian Power Bowl: Skip chicken, double beans, add 1 cup green lentils and 2 cups diced mushrooms. Use vegetable stock and finish with spinach.
Apple-Cider Twist: Replace ½ cup stock with apple cider and stir in diced Granny Smith apple in the last 30 min for sweet-tart contrast.
Grains & Greens: Add ½ cup pearled barley or farro at step 4; they’ll cook gently. Stir in chopped kale before serving for color.

Storage Tips

Refrigerate: Cool stew to room temperature within 2 hours. Transfer to airtight containers; keep 4 days. The squash will continue absorbing broth—thin with stock or water when reheating.

Freeze: Portion into quart-size freezer bags, press out air, lay flat to freeze (saves space). Keeps 3 months. Thaw overnight in fridge, then warm gently to prevent beans from splitting.

Make-ahead: Chop vegetables the night before; store in a zip bag with a paper towel to absorb moisture. Sear chicken in the morning while your coffee brews; everything else takes 3 minutes.

Reheat: Microwave at 70 % power, stirring halfway, or simmer on stovetop over low. Add a squeeze of fresh lemon to wake up flavors.

Frequently Asked Questions

Yes, but the broth will be thinner. Add 1 Tbsp gelatin powder or simmer with bones saved from a roast to mimic silkiness. Reduce cook time by 1 hour on LOW.

The peel softens and is edible—plus it adds color. If you prefer silky texture, remove using a spoon after cooking or peel before cooking with a sturdy vegetable peeler.

Stir in another pinch of salt, a squeeze of lemon, or ½ tsp fish sauce for umami. Bright herbs like parsley or chives wake up long-cooked flavors instantly.

Yes—4 hours on HIGH works, but collagen won’t fully dissolve, so the broth will be lighter. If you’re rushed, microwave vegetables 3 min to jump-start softening.

Absolutely. Serve as-is or over rice. If adding barley, choose certified gluten-free grains or stick with potatoes to maintain GF status.

Use a 7- to 8-quart slow cooker. Keep liquid ratio the same—squash exudes extra moisture. Stir once midway to ensure even heating. Freeze half for a no-cook night.
