Ingredients You'll Need

Russet potatoes are the classic choice here—they break down slightly during slow cooking, naturally thickening the broth while still holding their shape. Look for firm potatoes without green spots or soft eyes; store them in a cool, dark place (never the fridge). If you prefer a waxy potato, Yukon golds work, but the stew will be less creamy. For the ham, use thick-cut deli ends, leftover holiday ham, or even a smoked ham steak diced into ½-inch cubes. The smoky saltiness seasons the entire stew, so skip adding extra salt until you taste at the end. Carrots and celery contribute earthy sweetness and aromatics; choose carrots with bright color and celery that snaps crisply. Yellow onion mellows beautifully over the long cook time—save your sweet onions for raw applications. Chicken broth is the liquid backbone; low-sodium is best so you control salinity. Whole milk enriches the broth without the weight of heavy cream; 2 % works in a pinch but avoid skim—it can curdle. Cornstarch is the thickener; whisk it with cold milk first to prevent lumps. A bay leaf quietly perfumes everything, while dried thyme and a whisper of smoked paprika echo the ham’s flavor. Fresh parsley stirred in at the end lifts the whole dish with color and freshness.

How to Make Slow Cooker Creamy Potato and Ham Stew for Cold Weather

Prep the vegetables

Peel potatoes and cut into ¾-inch cubes; place immediately into the slow cooker to prevent browning. Dice carrots and celery into ¼-inch pieces so they soften evenly. Finely chop the onion—larger pieces stay too crunchy over the long cook time.

Layer flavors

Add ham, bay leaf, thyme, smoked paprika, and a generous grind of black pepper to the slow cooker. Avoid salting now—ham varies in saltiness. Stir gently to distribute aromatics among the vegetables.

Add broth

Pour in cold chicken broth; it should just cover the solids. If you need more liquid, add water rather than more broth—too much stock makes the stew salty. Give everything a gentle stir, cover, and set to LOW for 7–8 hours or HIGH for 4 hours.

Make the slurry

About 30 minutes before serving, whisk cornstarch into cold milk until completely smooth. Remove 1 cup of hot broth from the slow cooker and whisk it gradually into the milk mixture to temper; this prevents curdling when you add it back.

Season and serve

Fish out the bay leaf. Taste and adjust with salt, pepper, or a splash of lemon juice if it needs brightness. Stir in chopped parsley for color. Ladle into warm bowls and serve with crusty bread or cheddar biscuits.

Expert Tips

Low and slow wins

Resist the urge to cook on HIGH for convenience; the potatoes need the gentle heat of LOW to release starch and thicken naturally.

No curdling

Make sure the milk is cold when you whisk in cornstarch and always temper with hot broth before adding to the crock.

Keep the lid on

Every peek releases steam and adds 15–20 minutes to cook time. Trust the process; only remove the lid to add the slurry.

Overnight prep

Chop everything the night before; store potatoes in water in the fridge. In the morning, drain and dump—breakfast is faster.

Double batch trick

If your slow cooker is 6-quart or larger, double the recipe and freeze half in quart bags; lay flat for space-saving storage.

Brighten at the end

A teaspoon of Dijon mustard or a squeeze of lemon wakes up flavors muted by long cooking. Add just before serving.

Variations to Try

Cheddar & Broccoli

Swap half the potatoes for bite-size broccoli florets added during the last 90 minutes. Stir in 1 cup shredded sharp cheddar with the slurry for broccoli-cheese vibes.

Smoky Kielbasa

Replace ham with sliced kielbasa and add ½ tsp caraway seeds with the other spices for Eastern-European flair. A dollop of sour cream on top is divine.

Veggie-loaded

Stir in 2 cups baby spinach and 1 cup frozen corn during the last 15 minutes. The spinach wilts instantly and corn adds pops of sweetness.

Spicy Cajun

Add 1 tsp Cajun seasoning and a chopped bell pepper. Finish with Crystal hot sauce and sliced green onions for a Louisiana twist.

Dairy-free

Replace milk with unsweetened oat milk and thicken with 2 Tbsp instant potato flakes instead of cornstarch for a gluten-free, dairy-free option.

Herbaceous Spring

Swap thyme for fresh dill and add 1 cup frozen peas in the last 10 minutes. Bright, grassy flavors turn this winter stew into a spring meal.

Storage Tips

Allow leftovers to cool completely, then ladle into airtight containers. The stew will thicken as it cools; thin with a splash of broth or milk when reheating. Refrigerate up to 4 days or freeze up to 3 months. For individual lunches, freeze in 2-cup souper-cubes; pop one out and microwave for 4–5 minutes, stirring halfway. Thaw overnight in the fridge for best texture, though the microwave’s defrost setting works in a pinch. When reheating on the stovetop, warm gently over medium-low heat to prevent curdling; whisk occasionally. If you plan to freeze, slightly undercook the potatoes so they stay firm after thawing. Label bags with the date and a reminder to add fresh parsley for bright flavor on reheating.

Frequently Asked Questions

Absolutely—use smoked turkey if possible for depth. If using unsmoked turkey, add ½ tsp smoked paprika or a small ham hock for that essential smoky backbone.

Mix 1 Tbsp cornstarch with 2 Tbsp cold water and stir into hot stew; cover and cook 10 minutes more. Alternatively, mash a handful of potatoes against the side of the insert and stir to release natural starch.

Yes—simmer covered over low heat for 45–60 minutes until potatoes are tender, stirring occasionally. Add the slurry during the last 5 minutes and simmer until thickened.

As written, yes—cornstarch is the thickener. If you swap for flour, use an equal amount of gluten-free all-purpose blend.

Stir in 1 cup shredded sharp cheddar or Gruyère after the slurry step; cover until melted. Avoid pre-shredded cheese—it can become grainy.

Cut potatoes into uniform ¾-inch pieces and cook on LOW. If you must use HIGH, check at 3 hours; they may be done sooner. Russets hold better than Yukon golds under long heat.
