- 2 cups (300 g) cooked ham, diced
- 1 small onion, finely chopped
For the Cheese Sauce
- 4 tablespoons unsalted butter
- 4 tablespoons all-purpose flour
- 2½ cups (600 ml) whole milk
- 1 cup (240 ml) heavy cream
- 2½ cups (250 g) shredded cheese (Cheddar, Colby-Jack, or a blend)
- ½ teaspoon salt
- ½ teaspoon black pepper
- ½ teaspoon paprika
- ¼ teaspoon garlic powder
Optional Toppings
- ½ cup breadcrumbs or crushed crackers
- 2 tablespoons melted butter
- Fresh parsley or chives for garnish
Choosing the Best Potatoes
Potatoes are the backbone of this casserole. The right choice ensures a creamy texture rather than a watery or mushy result.
Best potato options:
- Yukon Gold – creamy and buttery
- Russet potatoes – soft and fluffy
- Red potatoes – slightly firmer, good for structure
Slice potatoes thinly and evenly so they cook at the same rate.
Preparing the Potatoes
Bring a large pot of salted water to a boil. Add the sliced potatoes and cook for 5–7 minutes, just until slightly tender but not fully cooked.
Drain well and set aside. This step ensures the casserole bakes evenly without raw potatoes in the center.
Making the Creamy Cheese Sauce
Creating the Roux
In a large saucepan over medium heat, melt the butter. Add the flour and whisk constantly for about 1 minute until smooth. This forms the base of your sauce and removes the raw flour taste.
Adding Milk and Cream
Slowly pour in the milk while whisking continuously to prevent lumps. Once smooth, add the heavy cream. Continue stirring until the sauce thickens slightly.
Adding Cheese and Seasoning
Lower the heat and gradually stir in the shredded cheese until melted and smooth. Season with salt, pepper, paprika, and garlic powder.
The sauce should be thick, creamy, and rich—but still pourable.
Preparing the Ham
Dice the cooked ham into bite-sized pieces. Smoked or honey ham works beautifully, adding depth and a hint of sweetness.
If using leftover holiday ham, this recipe is an excellent way to give it new life.
Assembling the Casserole
Layering the Ingredients
Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch (23×33 cm) baking dish.
Layer half of the potatoes in the bottom of the dish. Sprinkle with half of the diced ham and half of the chopped onion.
Pour half of the cheese sauce evenly over the layer.
Repeat with remaining potatoes, ham, onion, and cheese sauce.
Optional Crunchy Topping
Mix breadcrumbs or crushed crackers with melted butter and sprinkle evenly over the top for a crispy finish.
Baking the Casserole
Cover the casserole with aluminum foil and bake for 30 minutes.
Remove the foil and continue baking for another 20–25 minutes, or until the top is golden brown and the casserole is bubbling around the edges.
Let it rest for 10–15 minutes before serving. This helps the layers set and makes slicing easier.
Texture and Flavor Notes
A perfect Cheesy Ham Potato Casserole should be:
- Creamy but not soupy
- Tender potatoes that hold their shape
- Savory, smoky ham in every bite
- Rich cheese flavor without being greasy
The balance of cream, cheese, and starch creates a luxurious texture that feels indulgent yet comforting.

Common Mistakes to Avoid
