Slow Cooker Turkey & Winter Squash Stew with Garlic and Lemon

The first time I tested this stew I was knee-deep in January blues—grey skies, bone-cold wind, and a to-do list longer than my grocery receipt. I needed something that felt like sunshine in a bowl yet still honored the season. A single bite of this silky, citrus-kissed stew flipped the script: shredded turkey that melted like down feathers, winter squash that tasted like it had been slow-roasted in a wood-fired oven, and a mellow garlic-lemon broth that somehow tasted bright and cozy at once. Now it’s the recipe I lean on for busy weeknights, Sunday meal-prep, and every pot-luck where I want to bring something healthy that doesn’t scream “diet food.” If you can peel squash and smash a few garlic cloves, you’re twenty minutes away from a set-it-and-forget-it dinner that perfumes the house with promises of good things to come.

Why This Recipe Works

Hands-off comfort: Dump, stir, walk away—dinner is ready when you are.
Lean protein powerhouse: Turkey breast keeps the stew light while staying supremely tender.
Winter squash magic: Butternut or kabocha naturally thicken the broth—no cream needed.
Bright finish: Fresh lemon lifts the richness so each spoonful tastes vibrant, not heavy.
Garlic two ways: Slow-cooked cloves for sweetness, a last-minute grate for punch.
Freezer-friendly: Make a double batch; leftovers reheat like a dream.
One pot, five servings of veggies: A stealthy way to hit your daily quota.

Ingredients You'll Need

Great stew starts at the grocery store. Look for a turkey breast portion that’s pale pink, never grey, and still has a thin layer of skin—this bastes the meat as it slow-cooks. For the squash, choose one that feels heavy for its size; a 2 lb (900 g) butternut yields about 3 heaping cups of cubes, perfect for six generous bowls. Garlic heads should be tight and unblemished; skip pre-peeled cloves which can taste tinny. Finally, grab unwaxed lemons if possible—the zest is where the floral oils live, and you want every speck.

Turkey: Boneless skin-on turkey breast is my goldilocks cut; substitute skinless if you prefer, or swap in bone-in thighs for a richer stew—just add 60 extra minutes on low. Not a turkey fan? Chicken breast works, but reduce the first cook time by 30 minutes so it doesn’t dry out.

Winter squash: Butternut is classic, but kabocha or red kuri give an almost custard-like texture. Avoid spaghetti squash; it’ll turn to threads and disappear into the broth. Short on time? Buy pre-cubed squash, still rock-hard and refrigerated.

Garlic: We’re using a whole head—eight cloves go in at the beginning to mellow into sweet, spreadable nuggets, and two raw cloves finish the stew for that unmistakable pop.

Lemon: Zest + juice. The zest steeps in the stew for subtle bitterness; the juice is stirred in at the end for sparkle. Meyer lemons add honeyed sweetness if you can find them.

Chicken stock: Low-sodium lets you control salt. Vegetable stock is fine, but you’ll lose some depth. Water plus 2 tsp bouillon paste is an economical substitute.

How to Make Slow Cooker Turkey & Winter Squash Stew with Garlic and Lemon

Brown the turkey (optional but worth it)

Pat the turkey breast dry; season generously with 1 tsp kosher salt, ½ tsp black pepper, and 1 tsp dried thyme. Heat 1 tbsp olive oil in a skillet over medium-high. Sear turkey skin-side down 3 minutes until golden. Flip and slide into the slow cooker. The fond left in the pan equals free flavor; deglaze with ¼ cup stock, scrape, and pour those browned bits over the turkey.

Build the aromatic base

While the skillet is still hot, add diced onion and celery; sauté 4 minutes until translucent. Stir in tomato paste; cook 1 minute to caramelize. Add mixture to slow cooker along with bay leaves, smashed garlic cloves, and lemon zest strips (use a vegetable peeler for big pieces you can fish out later).

Load the squash & liquids

Pile squash cubes around—not on top of—the turkey; they’ll steam evenly. Pour in 3 cups stock and ½ cup dry white wine (or extra stock). The liquid should reach ¾ of the way up the turkey; add more if your cooker runs hot. Season with ½ tsp salt, keeping in mind reduction.

Slow cook to perfection

Cover and cook on LOW 5–6 hours or HIGH 2½–3 hours, until turkey registers 165 °F/74 °C on an instant-read thermometer and squash is fork-tender. If you’re out all day, use the “keep warm” setting after 6 hours; the stew holds beautifully for 2 extra hours without drying.

Shred & return

Transfer turkey to a cutting board; rest 10 minutes so juices redistribute. Discard skin (or nibble it—chef’s treat). Shred meat with two forks, then stir back into the stew. Discard bay leaves and large zest strips. Taste; adjust salt.

Finish with brightness

Grate the remaining 2 raw garlic cloves directly into the pot. Stir in 2 tbsp fresh lemon juice, 1 tsp honey to balance acidity, and a handful of chopped parsley. The raw garlic mellows after a minute but keeps the stew lively.

Serve & garnish

Ladle into warm bowls. Top with a drizzle of good olive oil, extra black pepper, and—if you’re feeling fancy—a few lemon-zest curls. Crusty sourdough or warm naan is non-negotiable for sopping up the garlicky broth.

Expert Tips

Use a thermometer

Poultry can go from juicy to chalky fast. Pull at 165 °F for shreddable turkey that still feels luxurious.

Overnight = deeper flavor

Make the stew the day before; refrigerate overnight. Reheat gently—the lemon and garlic meld into something magical.

Thin or thicken

Prefer soupier? Add hot stock at the end. Want stew thicker? Mash a cup of the squash against the pot wall and stir back in.

Save the rind

Toss Parmesan rind into the slow cooker with the stock. Remove before serving; it adds umami without dairy in the final broth.

Quick-soak beans

Stirring in a drained can of white beans? Warm them in the microwave first so they don’t cool the stew.

Color pop

Add a handful of baby spinach in the last 2 minutes; it wilts instantly and gives the stew restaurant-worthy color contrast.

Variations to Try

Moroccan twist: Swap thyme for 1 tsp each cumin & coriander, add ½ tsp cinnamon, ¼ cup chopped dried apricots, and finish with cilantro instead of parsley.
Creamy coconut: Replace 1 cup stock with full-fat coconut milk and stir in 2 tsp Thai red curry paste for subtle heat.
Instant-pot shortcut: Sauté using the pot, then high-pressure manual 12 minutes, natural release 10 minutes. Shred turkey and proceed with lemon finish.
Vegan route: Sub 2 cans chickpeas for turkey, use veggie stock, and stir in ¼ cup nutritional yeast at the end for savory depth.
Grains in one pot: Add ½ cup rinsed farro during the last 45 minutes on low; it plumps up and soaks flavor like risotto rice.
Smoky version: Stir in ½ tsp smoked paprika and replace ¼ cup stock with liquid from canned chipotle peppers for a gentle, smoldering heat.

Storage Tips

Refrigerator: Cool completely, then store in airtight containers up to 4 days. The squash continues to absorb broth, so thin with stock or water when reheating.

Freezer: Portion into zip-top bags, press out air, label, and freeze flat up to 3 months. Thaw overnight in the fridge, then warm gently—avoid rapid boiling which can shred squash into mush.

Make-ahead for parties: Cook the stew fully, refrigerate, and reheat in a Dutch oven over low 20 minutes. Add fresh lemon juice and herbs just before guests arrive for maximum brightness.
