Slow Cooker Scalloped Potatoes with Ham are a yummy crock pot recipe that turns leftover ham into a whole new meal!
Ham at Easter and at Christmas was always a tradition in my house while I was growing up. I still love having ham during the holidays.
However, after a day or so of reheating the leftovers, it’s nice to turn some of the food into a whole new meal. These Slow Cooker Scalloped Potatoes with Ham are the perfect way to do that!
These cheesy potatoes are a yummy main dish. They take a little more work than a toss-and-go slow cooker meal, but it’s so worth it!
How to make
Line slow cooker with a foil collar against the back half of the cooker, and spray slow cooker insert with nonstick cooking spray.
Microwave potatoes and 2 tablespoons milk in a covered bowl, stirring twice, for 6-8 minutes, or until almost tender. Uncover, and set aside to cool slightly.
While the potatoes are in the microwave, melt butter in a large saucepan. Add garlic and thyme; cook for 30 seconds.
Stir in remaining milk, broth, cornstarch, and pepper.
Bring milk mixture to simmer, whisking constantly, until just thickened.
Whisk in cheese, and stir until cheese has melted.
Remove from heat. The sauce should be nice and pourable. If it’s too thick, stir in additional chicken broth.
Pour about 1/3 cheese mixture over the bottom of the slow cooker.
Layer the potatoes in, overlapping as you go.
Top potatoes with diced ham. Pour cheese sauce over the top, spreading as necessary.
Cover and cook until potatoes are tender, about 4-6 hours on low.
Remove foil collar, and let potatoes cool for 20 minutes before serving.
What is a foil collar?
A foil collar is aluminum foil that’s placed against the hotter side in the slow cooker insert to help the food cook evenly. Typically, the back side is the hotter side of the slow cooker.
How to make a foil collar
To make a foil collar, fold 2-3 sheets of heavy-duty aluminum foil to form a rectangle that’s about 16 inches long. Press the collar against the hot side of the slow cooker insert before placing any food in the slow cooker insert.
Evaporated milk: Regular, low-fat, or fat-free ok.
Chicken broth: I like to use reduced-sodium broth in this recipe.
Thyme: If you don’t like thyme, feel free to omit it.
Cheese: You can use different types of cheese if you prefer.
Ham: I use leftover cooked ham. I don’t recommend using thin lunchmeat-style ham.
This recipe does not hold well on warm.
Prep ahead tips
If you are short on time, some of the prep can be done ahead of time.
You can grate the cheese, cut up the ham, and then store the cheese and ham in containers in the fridge until you’re ready to use them.
This recipe does not hold well on warm. Store the leftovers, covered, in the fridge for up to 4 days.

Have made this twice & everyone loves it!!
I’m so glad to hear that!
Love these scalloped potatoes & ham with only a couple substitutions/ additions it’s perfectly scrumptious!!! I used left-over ham gravy instead of broth & corn starch. Added bell pepper (red is what I had) & sour cream to this recipe.
Yay! So glad that you liked it!
This looks like a great mid-week meal! Was thinking of making a couple slight modifications to timing and potatoes for our family’s crazy schedule & preferences… We like skins-on for potatoes, even when sliced, and that’s what we do when we make scalloped the traditional way; would that mess up a crock pot cook? Also, crock pot will be on overnight, so cook time will be 7-8 hours on low, so I was thinking of NOT microwaving the slices before layering (didn’t want to make mushy more likely). Thoughts please on these changes, anyone? Thank you!
Hi! I haven’t tried those timing changes or leaving the skins on, so I’m afraid that I’m not sure. I’m hoping someone else may have tried it.
Fantastic! I found this recipe when I was looking for a recipe to use leftover ham. It was gobbled up! I’ll make it again when I have leftover ham. Thanks!
Make it a little quicker could frozen hash browns be used?
I think frozen hash browns will cook differently, but I think with some experimenting it could work. Good luck! =)
Is the microwaving of the potatoes necessary if it so going to be cooking 4-6 hrs and they are cut?
It helps to give the potatoes a head start. Low is only about 190F, so microwaving the potatoes helps to get them going.
What is the purpose of the foil on 1/2 of the pot? Can a slow cooker bag be used instead?
The foil collar helps distribute heat. Many slow cookers have a hot spot, and the foil collar helps to avoid over-cooked food in those areas. I haven’t tried this recipe with a slow cooker bag, but I think it’s a good idea.

Can u cook on high 4 hours?
I’ve never tried cooking it on high so, unfortunately, I can’t say for sure.
I have a 2 qt. Crock pot and I was wondering if I can cut the recipe down to half?
I haven’t tried this recipe with a 2 quart, so I’m not sure how well it will work.
Can I make this the night before and assemble and then cook it in the crock pot the next day?
I’ve never tried assembling it the night before. I’m not sure how the potatoes would hold up, but if you try it, I’d love to hear how it turns out. Good luck!
Do you do a layer of potatoes then ham, etc. and repeat or is it only a single layer of each ingredient? Thank you!
It’s just a layer of potatoes, then ham, and then cheese sauce. Please let me know if you have any other questions!
Any time! =)

Wonderful recipe.I like this and I think this is very delicious.
I am going to make this recipe for my family and husband
Thanks for sharing
Thanks! Hope you enjoy it as much as we do! =)
Slightly worried that I might eat the entire batch of these before the guests even arrive– but hey, what’s life without a risk, right?! Seriously though, these look to. die. for.
Hey, the guests will never know! ;) Thanks, Karly!

They look good, I’ll give them a try. What is the point of the foil?
Thanks! Most slow cookers have hot spots, and the foil helps the food to cook more evenly.
