Slow Cooker Turkey & Sweet Potato Stew with Spinach

A soul-warming bowl of comfort that practically cooks itself—tender turkey, velvety sweet potatoes, and nutrient-packed spinach simmered in a fragrant broth that's been kissed by herbs and just enough spice to make your kitchen smell like autumn, no matter the season.

Last October, when the first real cold snap hit Chicago and my inbox was already filling up with holiday prep reminders, I found myself craving something that felt like a gentle exhale. Not another sheet-pan dinner, not a 30-minute skillet—something that would welcome me home at 6:30 p.m. with the promise of a meal that had been quietly taking care of itself all day. I wanted the culinary equivalent of flannel sheets and a crackling fire.

That Tuesday I tossed a pound of lean turkey, two diced sweet potatoes, and a fistful of baby spinach into my ancient slow cooker, poured in some stock, and whispered a prayer to the kitchen gods. Eight hours later I lifted the lid and was met with a scent so comforting it felt like a hug from the inside out. The turkey had relaxed into tender morsels, the sweet potatoes had melted into silky chunks, and the spinach had surrendered its bright green to the broth, leaving behind minerals and a whisper of earthiness. One bite and I knew: this would be the stew that carried us through the long Midwestern winter.

Since then, I've made it for new-parent friends, for a neighbor recovering from surgery, and for countless Sunday nights when the thought of Monday morning felt overwhelming. It is humble food that tastes like you tried harder than you did, and it scales beautifully for a crowd or tucks into the freezer for future-you who forgot to thaw dinner.

Why This Recipe Works

Set-it-and-forget-it: Ten minutes of morning prep rewards you with a finished dinner the moment you walk in the door.
Budget-friendly protein: Lean ground turkey delivers big flavor without the price tag of beef or lamb.
Sweet-potato magic: Their natural sugars caramelize slowly, thickening the broth and eliminating the need for cream or flour.
Spinach at the end: A last-minute handful wilts in the residual heat so you keep vibrant color and all the nutrients.
Freezer hero: Portion leftovers into quart bags, lay flat to freeze, and you've got a microwave-ready meal for up to three months.
One pot, zero dishes: Everything cooks in the ceramic insert—no browning step required—so cleanup is blissfully minimal.

Ingredients You'll Need

Great stew starts at the grocery store. Here's what to look for—and what you can swap if your pantry or wallet demands flexibility.

Lean ground turkey (93%) keeps the dish light while still giving you that satisfying meaty bite. If you only have 85% turkey, drain off the extra fat after the first hour of cooking or the broth will feel heavy. Not a turkey fan? Ground chicken works identically; if you're vegetarian, swap in two cans of drained chickpeas and reduce the stock by ½ cup.

Sweet potatoes should be firm, without soft spots or sprouting eyes. I like the copper-skinned Garnets for their deep orange flesh and extra beta-carotene, but any variety will do. Peel them just before dicing so they don't oxidize; ¾-inch cubes cook evenly and hold their shape without turning to complete mush.

Low-sodium chicken stock lets you control salt later. If you only have regular stock, hold off on seasoning until the end. Vegetable stock is fine, but chicken amplifies the savory notes. Homemade stock will make you feel like a domestic superhero, but the boxed stuff absolutely keeps this weeknight-friendly.

Baby spinach comes pre-washed and wilts in seconds. If you're using mature spinach, remove the thick stems and give it a rough chop so you don't end up with stringy bites. Frozen spinach works in a pinch—thaw and squeeze it dry, then stir it in with the lemon juice at the end.

Aromatics—yellow onion, garlic, carrot—form the flavor backbone. Dice them small so they melt into the stew and disappear, a trick that keeps picky eaters from fishing out "the chunky stuff."

Tomato paste adds umami depth without watering down the broth. Buy it in the squeeze tube if you hate wasting the can; you'll use it for pasta sauces and chili all winter.

Smoked paprika is the quiet MVP here. Just ½ teaspoon gives the illusion of bacon without any actual pork. If you only have regular paprika, add a pinch of cumin to mimic the smokiness.

Fresh lemon juice wakes everything up at the end. Bottled lemon juice tastes flat; if you don't have a fresh lemon, use 1 tablespoon apple-cider vinegar instead.

How to Make Slow Cooker Turkey & Sweet Potato Stew with Spinach

Brown the turkey (optional but worth it)

Set a large non-stick skillet over medium-high heat. Add the turkey, sprinkle with ½ teaspoon salt, and cook, breaking it into small pieces, until just cooked through—about 5 minutes. You're not looking for deep color here; you simply want to render a bit of fat so the meat stays separate in the stew instead of clumping into rubbery nuggets. Transfer the turkey to the slow cooker insert with a slotted spoon, leaving behind any liquid.

Build the base

To the insert add diced onion, carrot, garlic, sweet-potato cubes, tomato paste, smoked paprika, thyme, bay leaf, and black pepper. Pour in the stock and give everything a gentle stir so the tomato paste dissolves and no rogue clumps remain. Resist the urge to add salt now; as the stew simmers, liquid evaporates and flavors concentrate. You'll adjust seasoning at the end.

Set the slow cooker

Cover and cook on LOW for 7 to 8 hours or on HIGH for 4 to 5 hours. The stew is ready when the sweet potatoes are fork-tender and the flavors have married into one cohesive, aromatic pool. If you're home during the day, give it a quick stir halfway through to redistribute the veg, don't stress if you can't.

Finish with greens and brightness

Turn the cooker to WARM (or switch it off if your model doesn't have that setting). Fish out the bay leaf and discard. Stir in the spinach and lemon juice, cover, and let stand 5 minutes—just long enough for the leaves to wilt and turn a vivid green. Taste, then season with salt and additional pepper. The acid from the lemon should make the flavors sing; if the stew still tastes flat, add another squeeze.

Serve and swoon

Ladle into deep bowls and top with a swirl of Greek yogurt or a sprinkle of chopped parsley if you're feeling fancy. Crusty bread is non-negotiable for mopping up every last drop. Leftovers thicken overnight as the sweet potatoes continue to release starch; thin with a splash of stock when reheating.

Expert Tips

Overnight prep trick

Chop all veg the night before and store them in a zip-top bag with a paper towel to absorb moisture. In the morning, dump everything into the insert and you're out the door in under five minutes.

Chill broth first

Pour cold stock over the ingredients; starting with hot liquid can crack some ceramic inserts and it shortens the cooking window, leading to mushy sweet potatoes.

Speed option

If you own an Instant Pot, use the Slow Cook function on LOW for 6 hours with the glass lid. The tighter seal traps more moisture, so reduce stock by ¼ cup.

Salt at the end

Taste after the spinach goes in. Sweet potatoes drink salt, so the stew that seems perfectly seasoned at hour four may taste flat at hour eight.

Thickening hack

If you prefer a thicker stew, mash a cup of the sweet-potato cubes against the side of the insert with the back of a spoon and stir them back in.

Color pop

Add an extra handful of spinach to each bowl just before serving if you want that restaurant-style contrast of deep green against the sunset-orange broth.

Variations to Try

Moroccan twist: Swap smoked paprika for 1 tsp ras el hanout and add a handful of golden raisins during the last hour. Top with toasted sliced almonds.
Creamy version: Stir in ⅓ cup cream cheese cubes along with the spinach for a chowder-like richness.
Spicy kick: Add ¼ tsp chipotle powder and a diced chipotle pepper in adobo. Finish with cilantro instead of parsley.
Keto swap: Replace sweet potatoes with cauliflower florets and cook on HIGH for 3 hours so they stay al dente.
Lentil hearty: Skip turkey, add 1 cup rinsed red lentils and an extra cup stock. Puree half the stew for texture contrast.

Storage Tips

Refrigerator: Cool the stew completely, then transfer to airtight containers. It keeps up to 4 days, though the spinach will dull slightly in color after 48 hours—still tastes great. Reheat gently on the stove or microwave with a splash of stock or water.

Freezer: Portion into quart-size freezer bags, press out excess air, and freeze flat on a sheet pan. Once solid, stack like books. Thaw overnight in the fridge or submerge the sealed bag in a bowl of cold water for 30 minutes. Heat to 165°F before serving. Best within 3 months for optimal flavor.

Make-ahead lunch jars: Spoon 1½ cups stew into 16-oz wide-mouth jars, leaving 1 inch at the top. Cool, cap, and refrigerate up to 4 days. Grab-and-go portions reheat in 2 minutes; the glass won't stain and you can eat straight from the jar at your desk.

Frequently Asked Questions

Yes—use 90% lean ground beef and drain fat after browning. The stew will be richer; you may want to add an extra squeeze of lemon to balance.

You can skip it, but texture suffers. Raw turkey clumps and turns a bit rubbery. If you're in a rush, at least break the raw meat into tiny pieces as you add it.

They were either cut too small or cooked too long. Next time cut 1-inch cubes and check at 6 hours on LOW. Older slow cookers run hotter; consider upgrading to a model with temperature probe.

Only if your slow-cooker insert is 7 quarts or larger. Fill no more than ⅔ full to prevent overflow. Cooking time increases by 1 hour on LOW.

The recipe is naturally dairy-free. Skip the optional yogurt topping or use coconut yogurt for a tangy swirl.

Absolutely—use a heavy Dutch oven. Simmer covered on the lowest burner heat for 1½ hours, stirring occasionally, until sweet potatoes are tender. Add spinach and lemon at the end as directed.
