How to Make Cheesy Ham and Potato Casserole
This Cheesy Ham and Potato Casserole recipe comes together with simple layering and basic cheese sauce. The technique is foolproof.
Prep the Potatoes
Peel and slice potatoes into thin rounds about ⅛ inch thick using a sharp knife or mandoline. Thin slices are essential for cheesy ham and potato casserole with real potatoes that actually cook through.
Place sliced potatoes in a bowl of cold water to prevent browning while you prep the other ingredients. This keeps your cheesy potato and ham casserole looking fresh and white instead of oxidized and gray.
Make the Cheese Sauce
Melt butter in a large saucepan over medium heat. Add diced onions and cook for 3 to 4 minutes until softened and translucent without browning.
Whisk in flour and cook for 1 minute to create a roux base for your ham and cheesy potato casserole sauce. The roux thickens the milk and prevents thin watery sauce.
Add Dairy and Cheese
Gradually whisk in milk and heavy cream, stirring constantly to prevent lumps. Bring to a simmer and cook for 3 to 4 minutes until thickened enough to coat the back of a spoon.
Remove from heat and stir in shredded cheddar cheese, garlic powder, salt, and pepper. The cheese melts into the hot sauce and creates that creamy base for cheesy ham and potato casserole recipe success.
Layer the Casserole
Spray a 9x13 inch baking dish with cooking spray. Drain potato slices and pat them dry with paper towels to remove excess moisture.
Arrange one third of the potato slices in overlapping layers on the bottom of the dish. Top with half the diced ham spread evenly, then pour one third of the cheese sauce over everything.
Repeat Layers
Add another layer of potato slices, remaining ham, and more cheese sauce. Finish with final layer of potatoes and remaining sauce poured over the top.
The layering ensures every bite of your ham and potato casserole has potatoes, ham, and creamy cheese sauce. Cover the dish tightly with aluminum foil to trap steam.
Bake Until Tender
Bake covered at 375°F for 45 minutes until potatoes are tender when pierced with a fork. The foil traps steam that helps potatoes cook through without drying out the top.
Remove foil and bake uncovered for 15 more minutes until top is golden brown and bubbly. The uncovered time crisps up the top layer and creates that signature casserole texture.
Let the casserole rest for 10 minutes before serving. This resting time lets the sauce thicken and makes your cheesy ham and potato casserole easier to scoop without falling apart.

My Cheesy Ham and Potato Casserole Journey
First time I made Cheesy Ham and Potato Casserole I cut potatoes into thick chunks because I didn't want to spend time slicing them thin. The potato pieces stayed completely hard and crunchy even after baking for over an hour.
Had to keep putting it back in the oven and the ham dried out while the cheese sauce separated into a greasy mess. My family took one bite of the crunchy potatoes and suggested ordering pizza instead.
Tried again using properly thin sliced potatoes about ⅛ inch thick. Suddenly the potatoes cooked through perfectly in 45 minutes with creamy tender texture. The layers held together and every bite had that perfect combination.
Then I made the sauce too thin by using all milk and no cream. It was watery and pooled at the bottom instead of coating the potatoes. Started using heavy cream mixed with milk and got that thick creamy sauce that clings to everything.
Now I make this Cheesy Ham and Potato Casserole every time I have leftover ham from holidays. Thin sliced potatoes, thick creamy sauce, proper layering, and covered baking.
