Kristen's Keys for Cheesy Scalloped Potatoes with Ham

This recipe is very approachable, but a few small details make a big difference in how creamy, cheesy, and evenly cooked your potatoes turn out. Paying attention upfront saves you from undercooked potatoes or a ensures your sauce is perfectly creamy.

  • Opt for starchy potatoes. Either russet or Yukon Gold potatoes have enough starch to give these scalloped potatoes a creamy, rich finish.
  • Slice the potatoes thin. Aim to cut your potatoes into ⅛-inch thick slices, which will ensure the potatoes cook fully without the need to parboil them first.
  • Grate your own cheese. Pre-shredded cheese doesn't melt as smoothly because of added anti-caking agents. Taking a few extra minutes to grate it yourself gives you a sauce that's silky, not grainy.
  • No leftover ham? Purchase a ham steak of thick slice of ham from the deli or omit the ham altogether.

How to Make Cheesy Scalloped Potatoes and Ham

Think of this section as me walking you through exactly how I make these cheesy scalloped potatoes in my own kitchen.

Step One: Slice Potatoes

Wash and peel potatoes and then thinly slice into ⅛-inch thick slices. A mandoline makes this quick and consistent, but a sharp knife works too!

Step Two: Make the Cheese Sauce

Using a from-scratch cheese sauce gives these scalloped potatoes the best flavor and irresistibly creamy texture. It is well worth the 5 extra minutes it takes to make.

  • Melt butter in a small saucepan. Once melted, whisk in the flour to form a thick paste (AKA a roux) which will thicken the sauce.
  • Let the roux cook for a minute or two to remove any raw flour taste.
  • Slowly whisk the milk into the mixture until incorporated.
  • Simmer, stirring constantly, for just a couple minutes until the sauce thickens enough to coat the back of a spoon.
  • Once thickened, remove the pan from the heat and stir in the grated cheddar cheese until fully melted. Taking the pan off the heat before adding cheese prevents separation and keeps the sauce smooth.

Step Three: Assemble the Casserole

Layer half the potatoes in a buttered baking dish, followed by half the ham and half the cheese sauce. Repeat the layers. For extra cheesy goodness, top with additional shredded cheese.

Step Four: Bake

Cover the casserole dish tightly with foil and bake for one hour. Remove the foil and bake for an additional 25-35 minutes or until the potatoes are fork-tender and the sauce is bubbly.

Serving Suggestions

Cheesy Potatoes and Ham is one of those recipes that earns a permanent spot in the dinner rotation, whether served as the star of the show or as a supporting side dish.

Make-Ahead Instructions

When it comes to holiday meals, anything you can prep ahead is a small gift to your future self. Cheesy scalloped potatoes are no exception! For the best flavor and texture, it's best to bake them first and then reheat rather than assembling them ahead. This keeps the potatoes from discoloring and ensures the sauce stays creamy.

  • Prepare and bake the scalloped potatoes as directed.
  • Once baked, let them cool to room temperature, cover tightly with foil, then refrigerate for up to 3 days.
  • When you're ready to serve, take the dish out of the refrigerator about 30 minutes before reheating to take the chill off the dish.
  • Bake covered with foil, at 350°F for about 30 minutes, or until warmed through.

Equipment

Notes

Storage: Leftovers can be stored in an airtight container in the refrigerator for 3-4 days and reheated as desired in the microwave. 
Sodium: If you are using very salty or smoked ham, decrease the amount of salt to ½ teaspoon. 
How Many Potatoes: You will need about 3 pounds of potatoes or 3 large Russet potatoes and 4 large Yukon gold potatoes, to equal 6 cups of sliced potatoes. 
Note on Par-Boiling Potatoes: I do not find it necessary to parboil your potatoes before baking. However, if you want your potatoes fall-apart tender,  you can opt to parboil your potatoes before baking. I recommend parboiling the potatoes whole in salted, simmering water for 7 to 9 minutes. Drain, let the potatoes cool, and then thinly slice. You don't want to slice your potatoes prior to parboiling, as they will become waterlogged. 
Casserole Dish: Any 2 or 3-quart oven-safe casserole dish will work as long as it is deep enough to pour the cheese sauce over.
Make-Ahead Instructions: Prepare and bake the scalloped potatoes as directed. Let cool to room temperature, cover tightly with foil, and refrigerate for up to 3 days. Let the dish sit at room temperature for 30 minutes before reheating. Then, bake at 350°F, covered, for about 30 minutes, or until warmed through.

    Saw this recipe online and decided to try it for dinner this evening. What a hit this casserole turned out to be for my husband and son. Made it with a small thinly sliced onion on the mandolin like Davey mentioned in your comments and what an absolutely delicious dish this was! Thank you for the great recipe. It will become one of our family's favourites.

    1. YAY!!! I love hearing when people love my recipes--especially when the family enjoys! And I am with you and Davey, I love the addition of onions--but my kids not so much 😉 I hope you enjoy this recipe for years to come.

  2. 4 stars
    Do you mean to say that you were the first person to think of putting ham into a potato casserole? Then you must have a time machine! LOL. Because my mom used to make this all the time when I was a kid many years ago. She would add thinly sliced onions onto the layers of potatoes, and I dare say there was even Velveeta added on occasion for creaminess. Always a family favorite!

    1. Davey, I certainly was NOT the first person to think of this recipe. Just the first person in my family 😉 My dad always just did potatoes and onions and we loved it--the ham just made this side dish worthy of being an entree!

      1. I made this last night, with the addition of thinly sliced onions (once you have the mandolin out, it's hard not to keep using it!) and it was awesome! Thanks for the inspiration.

      2. You bet! And Davey, I think next time I make this, I will add onions myself!

    I made this for dinner last night. I followed the recipe without making any adjustments and it was DELICIOUS. All three of us loved it and since we still have some ham and potatoes, I might make it again tonight!

  4. I made this today, it didn't turn out quite as I had hoped. I was expecting scalloped potatoes with ham, i.e. potatoes and ham in a creamy, cheesy sauce, but after baking, the milk, cheese and flour had curdled into blobs leaving a clear watery liquid. The ham I used gave it a smokey tang, but also contributed salt, so the dish was on the verge of being too salty. I'd advise going easy on any added salt. All in all, the dish was tasty and enjoyable but a bit disappointing in texture and appearance.

    1. Hi Larry! I am sorry it was not as you expected. Let me help you trouble shoot: Did you allow the cream sauce to fully incorporate and cook for a few mintues to get thick before pouring on your potatoes and ham? Did you whisk the mixture well while cooking? Did you overcook the cream sauce by keeping on high heat? I have never had this mixture curdle, so I am trying to figure out why this could have happened for you.
      As far as the salty ham, that is a GREAT point, and I am going to add that to my notes. I used a very low sodium ham, so yes the salt amount should be adjusted for based on ham used.

      1. I am glad you still enjoyed the taste. As for the curdled texture--be sure to whisk flour fully into milk and heat over lower heat--what will help in the future.
