Ingredients You'll Need

Great stew starts at the grocery store, so let’s shop like we mean it. Look for boneless, skinless turkey thighs—dark meat is non-negotiable here. Breast dries out faster than my houseplants, while thighs forgive a long, lazy simmer and shred into silky threads. If your market only carries bone-in, add 30 minutes to the cook time and simply pull bones out at the end; the meat will slide right off.

Sweet potatoes should feel heavy for their size and have tight, unwrinkled skins. I like to grab one garnet and one Japanese purple for color contrast, but any variety works. Skip the monster-sized tubers; they tend to be fibrous. For the garlic, buy two whole bulbs. We’re using ten cloves—yes, ten—because slow heat tames their bite into mellow, spreadable nuggets.

Chicken stock is the backbone of flavor, so reach for low-sodium and taste later. Homemade is grand, but I’ve had excellent luck with the organic boxed stuff. Avoid “roasted” varieties; they can muddy the turkey. Canned fire-roasted tomatoes bring subtle smoky depth; if you only have regular diced, add ½ tsp smoked paprika to compensate.

Fresh thyme and bay leaves are worth the splurge—dried thyme becomes dusty over long cooking. If you must substitute, use ½ the amount dried and add it only in the last hour. A single cinnamon stick warms the background without screaming “dessert.” Finally, a modest splash of apple-cider vinegar at the end wakes everything up like a well-timed punchline.

How to Make Comforting Slow Cooker Turkey Stew with Sweet Potatoes and Garlic

Pat and Season the Turkey

Lay turkey thighs on a double layer of paper towels and press the tops dry—moisture is the enemy of browning. In a small bowl, whisk 1 Tbsp kosher salt, 1 tsp black pepper, 1 tsp sweet paprika, and ½ tsp dried oregano. Sprinkle mixture evenly over both sides of the meat, pressing gently so it adheres.

Optional but Worth It: Sear for Depth

If your slow-cooker insert is stovetop-safe, heat 2 Tbsp olive oil over medium-high. Sear turkey 3 minutes per side until chestnut-brown. No stovetop insert? Use a skillet, then deglaze with ¼ cup stock and pour every last brown bit into the cooker. This caramelized fond equals free flavor.

Build the Aromatic Layer

Scatter diced yellow onion and celery into the insert. Nestle turkey on top. Smash and peel garlic cloves; tuck them around the meat like edible treasures. Add cinnamon stick, bay leaves, and thyme sprigs. These will perfume the stew for hours.

Load the Sweet Potatoes

Peel sweet potatoes and chop into 1-inch cubes—any smaller and they dissolve; larger stays toothsome. Arrange them on top so they steam rather than mush. Pour in entire can of fire-roasted tomatoes (juice included) and 2½ cups stock. The liquid should barely kiss the bottom layer of potatoes; resist adding more or you’ll dilute flavor.

Set It and Actually Forget It

Cover and cook on LOW 6–7 hours or HIGH 3–3½ hours. If you are leaving the house, place the insert on a folded kitchen towel in a rimmed baking sheet—an extra insurance policy against the rare crack leak.

Shred and Return

Turkey is ready when it yields easily to tongs. Transfer to a plate; discard any rogue thyme stems or bay leaves. Use two forks to shred meat into bite-size strands, trimming visible fat as you go. Return meat to the stew for at least 10 minutes so it reabsorbs juices.

Brighten and Thicken

Mash a handful of sweet-potato cubes against the side of the insert; stir to create a naturally creamy body. Add 1 tsp apple-cider vinegar and taste for salt. The stew should be thick enough to coat a spoon but still brothy—add a splash of stock or hot water to loosen if needed.

Serve with Personality

Ladle into shallow bowls over steamed rice or alongside crusty sourdough. Garnish with chopped parsley, a dollop of Greek yogurt, or—for the rebels—a few slices of pickled jalapeño for heat. Leftovers reheat like a dream and taste even better the next day.

Expert Tips

Overnight Maximizer

Prep everything the night before; keep the insert covered in the fridge. In the morning, set it on the base and hit START—no extra cook time needed.

Defat Trick

Let stew rest 15 minutes after cooking; fat will rise and pool on top. Lay a paper towel over the surface, swipe gently, and discard—no greasy spoonfuls.

Speed-Cool for Safety

Transfer insert to a sink filled with 2 inches of ice water; stir stew every few minutes. It drops to fridge-safe temps in under 30 minutes.

Color Pop

Add a handful of baby spinach in the last 3 minutes; it wilts to emerald ribbons and makes photos (and nutrition) sparkle.

Double-Thicken Option

Whisk 1 Tbsp cornstarch with 2 Tbsp cold water; stir into stew 30 minutes before finish for an even silkier texture.

Keep-Warm Hack

Most models auto-switch to WARM after cooking. Stir in an extra ½ cup stock to prevent scorching if holding longer than 1 hour.

Variations to Try

White-Bean Tuscan

Swap sweet potatoes for two cans of rinsed cannellini beans; add 2 tsp minced rosemary and zest of 1 lemon.
Smoky Southwest

Add 1 chipotle in adobo, 1 tsp cumin, and 1 cup frozen corn. Finish with cilantro and squeeze of lime.
Coconut Curry

Replace 1 cup stock with full-fat coconut milk; stir in 1 Tbsp red curry paste and 1 tsp grated ginger.
Harvest Apple

Fold in 1 peeled, diced apple and ½ cup dried cranberries during the last hour for sweet-tart bursts.
Kale & Barley

Add ½ cup pearl barley and 2 cups shredded kale; increase stock by 1 cup and cook 1 extra hour.

Storage Tips

Refrigerator: Cool completely, transfer to airtight containers, and refrigerate up to 4 days. The stew will thicken as the sweet potatoes continue to absorb liquid; thin with broth or water when reheating.

Freezer: Portion 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. Warm gently over medium-low heat, stirring often.

Make-Ahead Lunch Jars: Ladle stew into 2-cup mason jars, leaving 1 inch headspace. Top with a pinch of fresh herbs. Refrigerate up to 5 days; grab and microwave 2 minutes with the lid ajar.
