Old fashioned scalloped potatoes and ham is a great casserole for an everyday meal or potluck dinner. Made from scratch, this will be one of your favorite dinner recipes.
This is one of our favorite comfort foods. With these simple step by step photo instructions, you get it perfect results the first time and every time.
As usual, I read way too many recipes, but most were very similar. The inspiration piece will be a Pioneer Woman recipe on Food Network. But I could use several others as inspiration also. A few changes to simplify the instructions, add the step-by-step pictures, and decrease the fat some.
I know this is cooking for two, but this fits our lifestyle. Since it is the whole meal, we will eat a double amount, and I was cooking for leftovers, also.
This is a recipe that is easily cut in half, but for this amount of time and work, I want more return. But instructions for decreasing the size of the recipe is in the notes of the recipe card.
I had originally rated this a solid four, but with the evolution of the recipe with perhaps 25 repeat cookings, it has made it to the five range. Low 5 but still a 5 for me.
Scalloped vs. Au Gratin
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 or Au Gratin or Scalloped Au Gratin.
Take the cheese out and just use a white sauce and you have Scalloped but not Au Gratin. Now you know.
So, this could also be called Au Gratin potatoes and ham. I was brought up calling this scalloped, so I'm using that, but Au Gratin may be more correct.
All potatoes will cook about the same, so use what you want and have available, but usually, Russet potatoes are used. I like to leave the skin on but remove if you want.
The original recipe called for Monterey Jack, and I used that the first few times. Mostly I now use a mild cheddar. A nice Gruyere would be nice also.
The original recipes ( many of them) suggest total cooking times of 60-70 minutes. While it is "done," there is still a little firm in the potatoes that my wife and I don't like.
I have done this 20 plus times, and I now do a total of about 2 hours of total cooking time. So I have changed the instructions, but feel free to cook for the original recommended 40 minutes covered and 25 minutes uncovered if you want firmer potatoes.
This recipe is written for a full-size casserole of 9X13 inches. I'm calling that 8 servings, but we love the leftovers and try to cook for that. But, I do adjust this down some if I'm short on ham.
But many of you want a smaller "for two" or "for one" casserole. Here are the "cut in half" tips.
- Use a 6X9 or 8X8 pan.
- In the recipe card, adjust the number of servings to 4. That will do the math an change the ingredient amounts displayed. WARNING- this does not adjust the instructions, so you will need to follow the amounts in the ingredients and not the instructions.
- Cooking time does not change to a little shorter, so check a bit early.
Good refrigerated for 3-4 days and can be frozen for 3-4 months.

My Private Notes
- Easy to cut in half. See the instructions below.
- Use a mandolin to slice the potatoes to save your fingers and time. But be careful with the mandolin.
- Use potatoes of your choice, but I like Russets. Peeling is optional.
- Cheese of your choice. I use cheddar or Monterey Jack.
- The original recipes ( many of them) suggest total cooking times of 60-70 minutes. While it is done, there is still a little firm in the potatoes which my wife and I don't like. I have done this 20 plus times, and I now do a total of almost 2 hours total cooking time. So, I have changed the instructions but feel free to cook for the original recommended 40 minutes covered and 25 minutes uncovered if you want firmer potatoes.
- I scale this up or down depending on how much leftover ham I have.
- Good refrigerated for 3-4 days, and can be frozen for 3-4 months.
Instructions for half size:
- Use a 6X9 or 8X8 pan.
- In the recipe card, adjust the number of servings to 4. That will do the math and change the ingredient amounts displayed. WARNING- this does not adjust the instructions so you will need to use the amounts in the Ingredients, and not the Instructions.
- Cooking time does not change much, but check it a bit early.
To adjust the recipe size:
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.
