Tip: save now, make later.

When the lid comes off a slow cooker, the potatoes should be tender enough to give under a fork, not falling apart into a cloudy broth. That’s the balance I aim for with Crockpot Ham and Potato Soup: hearty chunks of potato and ham, with enough body in the broth to make each spoonful feel like soup rather than stew water.

I build that texture in two ways. Some of the cooked potatoes get mashed right against the side of the slow cooker, then a smooth mixture of heavy cream and flour goes in near the end. The potatoes give the soup a natural, rustic thickness; the cream mixture rounds it out without spending the whole day cooking. With carrots, celery, onion, thyme, and cooked ham in the pot, the finished bowls are warm, savory, and creamy.

Kitchen Note

Cut the potatoes into even half-inch cubes. Smaller pieces can soften sooner than the carrots, while uneven chunks make it harder to get the whole pot tender at the same time.

Save this Crockpot Ham and Potato Soup for tender potatoes, savory ham, and a creamy broth that thickens right in the slow cooker.

Why the Potatoes Give This Soup More Body Than Cream Alone

A slow cooker soup can have tender ingredients and still taste thin. Cream adds richness, but it doesn’t create the same hearty texture as potatoes that have released their starch and been partly mashed. That’s why I don’t rely on the cream mixture alone to thicken the pot.

Russet potatoes are especially useful here because they soften readily and mash into the broth. Pressing some against the side of the cooker gives the soup a thicker base while leaving other cubes intact. It’s a small change in texture, but it keeps the bowl from feeling like a smooth purée or a thin broth with vegetables floating in it.

The flour in the cream mixture adds another layer of thickness during the final cook. Whisking it smooth before it goes into the pot helps it blend evenly. Together, the mashed potato and flour-thickened cream make a substantial soup without needing a separate stovetop sauce.

What the Potatoes, Ham, and Cream Each Bring to the Pot

Russet potatoes — Their starch helps thicken the broth when you mash some of them. Peeling and cutting them evenly makes the texture more predictable; waxier potatoes won’t mash into the broth in quite the same way.
Cooked ham — It brings a salty, savory note and makes this a useful soup for leftover cooked ham. Dice it evenly so you get pieces throughout the pot. The ham’s saltiness varies, which is one reason low-sodium broth is a good choice here.
Low-sodium chicken broth — It gives the vegetables and ham enough liquid to cook while leaving more control over the soup’s seasoning. A lower-cost carton works well; choose a broth you like the taste of, since it forms most of the base.
Heavy cream and all-purpose flour — Whisked together, they give the finished soup a creamy, thickened consistency. The flour needs to be whisked in until smooth before the mixture goes into the cooker. For a dairy-free adaptation, see the variation below; it won’t have the same richness as heavy cream.
Onion, carrots, celery, thyme, and bay leaf — These build the familiar savory base without competing with the ham. Fresh, firm vegetables are a good choice, but there’s no need for specialty produce. Remove the bay leaf before serving; it seasons the pot but isn’t meant to be eaten.

Building the Soup in the Slow Cooker Without Losing the Potato Texture

Load the Slow Cooker Evenly

Add the potatoes, diced onion, carrots, celery, cooked ham, chicken broth, thyme, black pepper, bay leaf, and kosher salt to a 6-quart slow cooker. Stir to distribute the vegetables and ham through the broth. Keeping the potato pieces close to the same size helps them cook at a similar pace.

Cook Until the Potatoes Yield Easily

Cover and cook on LOW for 7 to 8 hours or HIGH for 4 to 5 hours. Check a potato with a fork near the end of the cooking window; it should pierce easily. If the center still feels firm, the potatoes need more time before you move on to thickening.

Mash Some Potatoes Into the Broth

Remove and discard the bay leaf before serving. Press some of the potatoes against the side of the slow cooker and mash them into the liquid. Leave plenty of potato pieces whole so the soup keeps a chunky, homey texture instead of turning uniformly smooth.

Stir in the Cream Mixture at the End

Whisk the heavy cream and flour in a bowl until the mixture looks smooth, with no dry pockets of flour. Stir it into the soup, cover, and cook on HIGH for 20 to 30 minutes, until the broth has thickened. Stir once more before serving so the creamy base is evenly distributed.

Three Ways to Adjust the Texture and Ingredients

A thicker, more rustic bowl

Mash more of the cooked potatoes against the side of the cooker before adding the cream mixture. The soup will have a heavier potato body and fewer distinct chunks, with no extra thickener needed.

A dairy-free finish

Leave out the heavy cream and use broth from the cooker to whisk with the flour until smooth, then stir it into the soup and finish cooking on HIGH. The result is less rich, with a broth-forward taste; mash some potatoes for a fuller texture. Use ham and broth without dairy ingredients if you need the entire dish to be dairy-free.

A flour-free, potato-thickened version

Omit the flour and mash more potatoes to thicken the soup. The finish will be less silky but still hearty. For a gluten-free meal, choose chicken broth and cooked ham that are gluten-free as well.

Storage and Reheating

Refrigerator: Store in a covered container for 3 to 4 days. The potatoes will continue to absorb liquid, so the soup may thicken as it chills.
Freezer: Freeze in airtight portions for up to 2 to 3 months. Cream-based soups can separate or turn slightly grainy after thawing, so the texture may be less smooth.
Reheating: Warm gently in a saucepan over medium-low heat, stirring often, until steaming throughout; avoid a hard boil, which can make the creamy texture less smooth. Add a splash of broth only if the chilled soup is too thick for your liking.

Questions I Get About Crockpot Ham and Potato Soup

Can I use leftover cooked ham?+

Yes. Dice cooked leftover ham and add it with the vegetables and broth. Since ham varies in saltiness, the low-sodium broth helps keep the finished soup from becoming overly salty.

Can I use a different kind of potato?+

You can, but the soup won’t thicken in quite the same way. Russets soften and mash into the broth readily; waxier potatoes tend to hold their shape more, so the base may feel thinner unless you mash more of them.

How do I fix a flour mixture that has lumps?+

Whisk the cream and flour together until smooth before stirring the mixture into the slow cooker. If you spot lumps before adding it, keep whisking in the bowl; flour pockets are harder to break up once they’re in the soup.

Can I add the cream mixture at the beginning?+

Add it after the potatoes are tender and some have been mashed. The cream and flour are meant to thicken the soup during the final 20 to 30 minutes, rather than cook through the full slow-cooking time.
