Why make this recipe
Ham and scalloped potatoes is a delicious casserole that's perfect for family dinners or potlucks.
Are you looking for a great casserole to make and use up leftover ham? This cheesy ham and scalloped potatoes is a perfect option.
You don't have to just wait until you have leftover ham though. You can make this with ham you buy at the store or leave the ham out altogether.
Other favorite recipes using leftover ham include this ham and rice casserole and this delicious ham tetrazzini.
Scalloped potatoes are very similar to au gratin potatoes. You could say they are cousins - scalloped potatoes often have cheese added to the dish. And of course these scalloped potatoes also have ham.
Key ingredients
- Potatoes - russet potatoes or Yukon gold
- Ham - cut into small cubes
- Onions - yellow or white onion
- Cheese - a mixture of cheddar and Monterey Jack
Slice the potatoes
The potatoes should be thin and evenly sliced. I used a mandolin to get perfect sliced potatoes.
If you don't have a mandoline, you can hand slice the potatoes. Try to keep them as evenly sliced as possible.
- Use a mandoline and slice the potatoes as thin as possible
- Slice each potato
- Continue until all potatoes are sliced
- Slice onion on mandoline too on the same setting or thickness
Step by step directions
- Layer potatoes in a greased baking dish
- Layer onions
- Sprinkle with flour and cheese and salt and pepper and add the ham and cheese
- Add another layer of potatoes
- Continue adding onions and ham, flour and cheese and salt and pepper
- Repeat with a third layer adding potatoes, onions and ham
- Pour milk over casserole and sprinkle with final cheese
- Cover with foil and bake in a 350° oven for 1 hour. Remove the foil and continue cooking for 30-45 minutes until potatoes are soft and cooked through.
Tips:
- Slice potatoes and onions evenly
- Evenly distribute ingredients through each layer
- Cover with foil before baking
- After 1 hour, remove foil and continue baking for 30-45 additional minutes
- Test to see if done by inserting a butter knife in the center. The potatoes should be soft and cooked through.
- Bake on a baking sheet to help prevent a mess in your oven, if the casserole bubbles over
- Allow dish to rest for 15 minutes before serving
Recipe FAQs
This is a perfect make ahead casserole dish. I often like to make this in the morning and refrigerate until it's time to pop into the oven.
This potato casserole does not freeze well.
Yes, this recipe can be doubled. However, the cooking time will increase due to a larger sized dish. Baking time may increase 30-45 minutes.

Hi just wondering about the flour, since it's not mixed , just sprinkled ? I assume that's how you're doing it ?
Kathy says
Hi Josephine,
The flour is just sprinkled lightly over each layer of potatoes and onions.
Enjoy! 🙂

Haven't tried it yet. I have all the ingredients to make it. Looks and sounds delicious. Can't wait for the family to try it. Big snow storm coming. Everyone will enjoy this!

Perfect meal to make on a cold snowy day! Stay safe and enjoy! 🙂
Kristine says
I want to make this for my large family. How would I adjust the baking time for a 9x13 pan?
Kathy says
Hi Kristine,
This casserole takes a long time to bake. To make a larger size, I would plan on adding 30-45 minutes of additional bake time. Keep the foil on until the final 30 minutes and keep an eye on it to make certain it doesn't overbake.
Enjoy!
Kathy 🙂

I loved this version! I was wondering as I made the layers how it would turn out and it was excellent! The onions cook down to give it a great taste with a tiny hint of sweetness and the flour makes a wonderful sauce with the Dijon, Thyme and milk. So Good! sending a copy of this to all my family and friends. Thanks for the recipe!!
Kathy says
Hi Melissa,

Scalloped potatoes are a total comfort food around here. My Mom used to make them growing up, but I haven't had them in years. We suddenly have a lot of time on our hands here...maybe digging back into Mom's cookbook is a good idea! But first, scalloped potatoes. And I feel like this one lends itself to fun different flavors of cheese, too!

Love the addition of ham here for extra flavour and heartiness! I don't need a main with this one! A big plateful and I'm one happy lady 😉 Delish, my friend!
