"5 stars. This recipe brought back great memories! It is actually better than my mom's."
This homemade scalloped potatoes and ham recipe is our favorite cheesy casserole we have made many times. A traditional recipe is perfect for using leftover ham from Easter or other holidays.
It is much easier to make from scratch than you would think using common ingredients with easy step-by-step photo instructions.
Make a half recipe for more of a "for two" size recipe if you want, but most people will have two servings, and the leftovers are wonderful.
👨🍳How to Make Scalloped Potatoes and Ham
1. Preheat oven to 350° convection or 375° conventional.
2. Scrub, peel, and slice 4 medium russet potatoes— 1 ½ to 2 pounds. Slice thin—about ⅜ inch thick. A mandolin is recommended if you have one. If you use a mandolin, please follow the manufacturer's safety instructions.
3. Chop 1 small onion. Chop or slice your ham into bite-size pieces.
4. Over medium-high heat, in a medium saucepan, melt 4 tablespoons of butter and add the onion. Cook until clearing—about 3-4 minutes.
5. Sprinkle in 4 tablespoons flour and mix well. Continue to cook and whisk for about 2 minutes until browning some.
6. Add 3 cups of milk slowly while continuing to whisk. Whisk and cook until thickening well—about 3-4 minutes. During this part, add 1 teaspoon salt and ½ teaspoon black pepper.
7. Prep a 9 by 13 inch casserole dish with a coat of butter.
8. Add about ⅓ of the sliced potatoes—top with ⅓ of the ham, ½ cup of shredded cheese, and ⅓ of the sauce. Repeat twice, but with the top layer, add the cheese last and double to a full cup.
9. Cover with aluminum foil.
10. Bake for 90 minutes, then uncover and cook another 20-25 minutes until nicely brown and bubbling. Allow to sit for about 10 minutes before serving—do not skip this step.

⏲️How long to cook scalloped potatoes and ham
It takes about 2 hours to get potatoes "fork tender" with no firmness to the potatoes.
Most reference recipes suggest a total cooking time of 60-70 minutes. While it is "done," the potatoes still have some firmness. Feel free to cook for the original recommended 40 minutes covered and 25 minutes uncovered if you want firmer potatoes.
✔️Tips to get it right every time
About the ham
This recipe is the perfect way to use leftover baked ham. If it has a sweet coating, like a honey glazed ham, rinse the sweet coating off under some running water.
Any ham that is "bit size" will work well. The amount of ham you use is flexible. About ¾ pounds and approximately 3 cups of sliced ham are suggested for this full-size recipe, but more or less is acceptable.
Dice ham will also work, but sliced ham is more traditional.
About the potatoes
Russet potatoes are usually used and should be peeled. Thinner-skinned potatoes like red or Yukon Gold potatoes may be used and don't need to be peeled. This recipe needs about 1 ½ to 2 pounds of sliced potatoes. A medium Russet potato is 6-8 oz.
Slice the potatoes about ⅜ inch thick but no thinner than ¼ inch thick. Use a mandolin if you have one, and please follow the manufacturer's safety instructions to prevent an unscheduled trip to the emergency room.
This recipe is for raw potatoes, not frozen potatoes, which will have an inferior texture. It is worth the little work to peel (optional) and slice.
The cheese choice is a personal choice. Usually mild cheddar cheese, but sharp cheddar, Monterey Jack, or Gruyere is also commonly used. Mixing in some mozzarella cheese will add some creaminess.
While shredded cheese will generally be fine, if you get grainy results, shred your own from a block of cheese.
The white sauce is a classic roux recipe and is easy to make with the instructions. For more details on making a roux, see How to Make Gravy from Scratch—Quick & Easy.
Do not skip letting the casserole rest for 10 minutes, which allows the sauce to set up and not be runny.

⬇️How to make this a "for two" friendly recipe
This recipe is easy to cut in half, from 8 to 4 servings, but the work doesn't decrease much.
- Use a 6X9 or 8X8 pan for a half recipe.
- Adjust the number of servings in the recipe card from 8 to 4. That will do the math and change the ingredient amounts displayed.
- The amounts listed in the instructions do not adjust, so you must follow the quantities in the ingredients and not the instructions.
- Cooking time will be slightly shorter, so check a bit early for fork tender.
How can I make scalloped potatoes and ham ahead?
Assemble completely and seal airtight. Refrigerate for 2-3 days. Freezing uncooked may change the texture and is not recommended. So, fully cook and cool before freezing for 1-2 months.
Serve ham and scalloped potatoes as a dinner entrée but will also work as a side dish. Since it is a heavy starch, serve it with a fresh green salad or a simple hot vegetable like corn, beans, or peas.
How to store leftovers?
For short-term storage of leftovers, seal well and refrigerate for 3-4 days. For longer-term storage, freeze for 1-2 months.
Reheating in the oven is preferred. If frozen, thaw overnight in the refrigerator before reheating.
Scalloped is anything baked in a casserole with a sauce that could be cheese or any other sauce. Au Gratin means “with cheese.” So this recipe could be called Scalloped Potatoes, Au Gratin potatoes, or Scalloped Au Gratin potatoes.

- Use potatoes of your choice, but I like Russets.
- Cheese of your choice. I use mild cheddar or Monterey Jack.
- The cooking time is longer than some other recipes. Discussed in the post.
- I scale this up or down depending on how much leftover ham I have.

You may adjust the number of servings in this recipe card under servings. This does the math for the ingredients for you. BUT it does NOT adjust the text of the instructions. So you need to do that yourself.
