Slow Cooker Turkey & Winter Squash Stew with Garlic & Herbs

When the first real frost kisses the pumpkin vines and the daylight savings sky goes dark before dinner, I reach for my biggest, coziest sweater and my slow cooker. This golden-hued turkey and winter squash stew has become our family’s official “welcome, winter” ritual. The aroma of rosemary and thyme drifting through the house while I ferry kids to piano lessons or fold laundry is the culinary equivalent of a weighted blanket: steady, reassuring, and deeply comforting.

I developed the recipe during a particularly hectic November when my husband was traveling, my parents were coming for Thanksgiving, and I needed dinners that could cook themselves while I prepped pie dough and brined the holiday bird. One spoonful and my mom declared it “better than anything from the fancy soup bar downtown.” My kids love it because the turkey stays fork-tender and the squash melts into velvety pockets that taste like candy. I love it because I can dump everything into the crockpot after school drop-off, ignore it all day, and still serve a nutrient-dense dinner that makes the house smell like I’ve been slaving away.

Whether you’re feeding a crowd on game day, need a make-ahead meal for new-parent friends, or simply crave something nourishing that won’t dirty every pot you own, this stew delivers. It’s gluten-free, dairy-free, and packed with lean protein, beta-carotene, and all the anti-inflammatory herbs your winter body is begging for. Let’s get slow-cooking.

Why This Recipe Works

Set-it-and-forget-it: 10 minutes of morning prep yields dinner at 6 p.m. with zero mid-day babysitting.
Lean & hearty: Turkey breast keeps the stew protein-rich without the heaviness of dark-meat stews.
Two kinds of squash: Butternut for silky body and delicata for caramelized edges—no peeling required.
Layered garlic: Fresh minced cloves, roasted garlic paste, and garlic powder create depth without bitterness.
Herb strategy: Woody stems cook all day; tender leaves are stirred in at the end for brightness.
Freezer hero: Makes a huge batch and thaws beautifully for up to 3 months.
One pot, five servings of veg: Checks the “eat the rainbow” box in a single bowl.

Ingredients You'll Need

Below are the star players, plus quick shopping notes so you walk into the store with confidence.

Protein

1 ½ lb (680 g) boneless turkey breast – Look for a natural, unseasoned roast that’s uniformly thick so it cooks evenly. Chicken breast or thighs work too, but turkey gives that cozy Thanksgiving vibe we’re after.

Winter Squash Duo

1 medium butternut squash (about 2 lb) – Choose one with a matte, tan skin and no green streaks. The neck should feel solid and heavy for its size. Peeled and cubed, it practically dissolves into the broth.
1 small delicata squash (12 oz/340 g) – The thin edible skin means less prep; its sweet, corn-like flavor intensifies during slow cooking. If you can’t find delicata, swap in an equal weight of peeled sweet potato.

Aromatics & Alliums

1 large yellow onion – Provides the savory backbone. Dice small so it melts into the stew.
4 cloves garlic, minced – Added at the beginning for mellow sweetness.
2 tsp roasted garlic paste – Optional but incredible; stir in at the end for a round, caramelized punch. Find it in the produce section near the fresh herbs.

Herbs & Spices

Fresh rosemary – One 4-inch sprig; woody stems hold up to long cooking.
Fresh thyme – Four sprigs. Don’t bother stripping leaves; the tiny leaves fall off naturally.
2 bay leaves – Remember to fish them out before serving.
1 tsp dried sage – Earthy bridge between poultry and squash.
½ tsp garlic powder – Reinforces fresh garlic without harsh edges.
¼ tsp freshly ground nutmeg – The subtle “what is that?” note that makes squash sing.

Liquid Gold

3 cups low-sodium turkey or chicken stock – Homemade if you have it; otherwise look for brands with “turkey” in the name for richer flavor.
1 cup canned pumpkin purée – Not pie filling. This thickens the stew and adds a velvet texture.
⅓ cup dry white wine – Adds acidity to balance sweet squash. Use something you’d happily drink.

Finishing Touches

1 cup frozen baby peas – Stirred in at the end for pop and color.
1 Tbsp apple cider vinegar – Brightens all the sweet elements.
Optional garnish: Toasted pepitas, a swirl of Greek yogurt, or crispy turkey bacon bits for crunch.

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

Brown the Turkey (Optional but Worth It)

Pat the turkey breast dry and season all over with 1 tsp kosher salt and ½ tsp black pepper. Heat 1 Tbsp olive oil in a large skillet over medium-high. Sear the turkey 2–3 minutes per side until golden. Transfer to a plate. The fond (those brown bits) equals flavor; we’ll deglaze in a moment.

Build the Aromatic Base

In the same skillet, add another drizzle of oil if the pan is dry. Toss in the diced onion and cook 3 minutes until translucent. Add minced garlic; cook 30 seconds. Pour in the white wine and scrape up every speck of browned turkey magic. Let the wine reduce by half—about 2 minutes—then scrape the whole mixture into the slow cooker.

Load the Crock

Add the cubed butternut and delicata to the cooker. Nestle the seared turkey on top. Tuck in rosemary, thyme, and bay leaves. Sprinkle sage, garlic powder, nutmeg, ½ tsp salt, and ¼ tsp pepper over everything. Whisk the pumpkin purée into the stock until smooth, then pour around (not over) the turkey so the herbs stay put.

Cook Low & Slow

Cover and cook on LOW 6–7 hours or HIGH 3½–4 hours, until turkey registers 165 °F/74 °C and squash is fork-tender. If your slow cooker runs hot, check at 5½ hours on LOW; turkey breast dries out quickly once overcooked.

Shred & Return

Transfer turkey to a cutting board and shred with two forks into bite-size pieces. Discard herb stems and bay leaves. Return shredded turkey to the pot and stir in roasted garlic paste if using.

Brighten & Thicken

Stir in frozen peas and apple cider vinegar. Replace lid and let stand 5 minutes; peas will turn bright green and the stew will thicken slightly as the squash continues to break down. Taste and adjust salt—depending on your stock, you may need another ½ tsp.

Serve & Garnish

Ladle into deep bowls. Top with toasted pepitas for crunch, a dollop of Greek yogurt for tang, or crispy turkey bacon if you’re feeling decadent. Crusty sourdough or cheddar biscuits on the side turn dinner into pure hygge.

Expert Tips

Size Matters

Cut squash into 1-inch cubes; any smaller and they’ll disappear into mush, any larger and they won’t cook through.

Herb Bouquet

Tie woody herbs with kitchen twine so you can fish them out in one swoop—no accidental rosemary stem chewing.

No-Wine Swap

Sub equal parts stock plus 1 Tbsp lemon juice for brightness if you’re avoiding alcohol.

Creamy Upgrade

For a creamier stew, whisk ¼ cup half-and-half with 2 Tbsp of the hot broth, then stir in during the last 10 minutes.

Crispy Skin Hack

If your turkey breast has skin, remove it after searing, bake at 400 °F for 10 minutes, and crumble on top for garnish.

Spice It Up

Add ¼ tsp smoked paprika and a pinch of cayenne for a subtle Southwest twist that plays beautifully with squash.

Variations to Try

Chicken & Sweet Potato: Swap turkey for boneless chicken thighs and use orange-fleshed sweet potatoes instead of squash.
Vegan Harvest: Replace turkey with two cans of chickpeas and use vegetable stock; add 1 Tbsp white miso for umami.
Green Veg Boost: Stir in 3 cups chopped kale or spinach during the last 15 minutes for an extra nutrient punch.
Apple & Sage: Add 1 diced tart apple and bump sage to 1½ tsp for a distinctly autumnal flavor reminiscent of sausage stuffing.
Curried Coconut: Sub 1 cup of stock with canned coconut milk and add 1 tsp yellow curry powder; finish with lime juice instead of vinegar.

Storage Tips

Refrigerate: Cool completely, transfer to airtight containers, and refrigerate up to 4 days. The stew will thicken as it sits; thin with a splash of stock when reheating.

Freeze: Ladle into freezer-safe quart bags, press out excess air, and freeze flat up to 3 months. Thaw overnight in the fridge or use the microwave’s defrost setting.

Make-Ahead: Chop all vegetables and aromatics the night before; store in a zip-top bag with the herb sprigs. In the morning, dump into the slow cooker with the turkey and liquids—breakfast prep time drops to 3 minutes.

Reheat: Warm gently on the stovetop over medium-low, stirring occasionally. Add a splash of stock or water to loosen. Microwave works too; cover loosely and heat 2 minutes at a time, stirring between bursts.
