Slow Cooker Vintage Ham and Potato Casserole is stick-to-your-ribs good! Smoky ham, potatoes and green beans in a cheesy sauce, what could be better?

This was great. All in one pot.

I found this ham and potato casserole recipe in my Amish-Country Cookbook and adapted it for the slow cooker. It’s full of cheesy sauce that keeps everything moist, with smoky ham flavor throughout and potatoes that turn perfectly tender after hours of slow cooking. This tastes like scalloped potatoes, but it’s a complete meal on its own.
Key Ingredients
Ham – Diced ham takes center stage in this vintage-inspired dish. Leftover holiday ham works perfectly and this is my favorite leftover ham recipe!
Potatoes – Sliced russet potatoes, skins left on give the dish a rustic flavor.
Green Beans – Fresh green beans cook along with the other ingredients adding a fresh bite.
Sauce Ingredients – A smooth mix of cream of chicken soup, milk, and seasonings coats every layer in creamy, savory goodness.

How to Make Ham and Potato Casserole
- Combine the soup, milk, and seasonings until smooth.
- Layer the potatoes, green beans, ham, onion, and part of the cheese, then pour the sauce over the top and stir to coat.
- Slow cook until the potatoes are tender, then add the rest of the cheese and let it melt before serving.



Tips & Variations
- Meat swap: You can swap out the ham for cooked ground beef, kielbasa or bacon for a change.
- Other Veggies: In addition to the other vegetables, you can add mushrooms or thin sliced carrots. You can even add peas or a pack of frozen mixed vegetables.
- Lower the sodium by using the heart healthy Campbell’s soup and omitting the salt.
- Cheese Swap – Try mozzarella, Swiss, or pepper jack instead of sharp cheddar for a different flavor.

What to Serve with Ham and Potato Casserole
- Toppings: Add a sprinkle of extra cheese and generous amount of freshly ground black pepper.
- Sides: Other sides to round out the old fashioned ham and potato casserole meal are a garden salad and dinner rolls.

How would I do this is the oven?
Hi! I don’t test my recipes in the oven so I can’t say with certainty.
This was great. All in one pot.
We made this for Easter dinner. Up to the time we added the cheese it tasted great. But – after we added the cheese it turned salty. All we could taste was the salt from the cheese. We were so disappointed after waiting all that time and we were not able to enjoy it. Too bad.
Don’t add any salt. There is more than enough in the canned soup.
This was excellent added some garlic bread.
Hello,
I am trying this recipe later this week. I was wondering if I could use frozen green beans or would that add too much water?
Also, could I cook this on high for 4 hours? My crockpot doesn’t have a 6 hour low setting. (There is a 6 hour high one though.)
Thanks
Great recipe to use left over ham. I used mushroom soup and corn becuase I didn’t have cream of chicken or beans. My kids don’t like onions so that didn’t go in. I really like how versatile your recipes are!! I use my crockpot at least twice a week and love using your recipes. They always turn out even when I have to substitute or take something out.
Thank you!!!!
Is the ham cooked already?
Most ham in the US is precooked and is actually safe to eat raw (read the label on yours). Yes, it’s cooked packaged ham. 🙂
I found these cute little bite sized potatoes so I just dumped in the whole lb besides about 12 wonky ones. I hate measuring anything I just put it on, eyeballing everything except the milk, cheese and spices. I can tell it’s going to be delicious and it was fairly quick to throw everything in and stir, especially not having to cut the tatos since theyre seriously tiny. Thank you so much for this recipe! Until then I have some extra fresh green beans to snack on
Fam loved it… my son ( who just bought his first house ) asked if I could make him a recipe book with all his favorite recipes! That is quite the compliment!
It’s in the crockpot now. Smells super delicious! Love having supper ready and so easily made. I had to use mushroom soup because I dint have cream of chicken soup on hand.
Thank you for the great idea.
