Ingredients

• 4 medium Potatoes
• 2 cups Ham
• 1 medium Onion
• 2 cups Sharp cheddar cheese, shredded
• 3 tablespoons Butter
• 3 tablespoons All-purpose flour
• 2 cups Milk
• 1 teaspoon Salt
• 0.5 teaspoons Black pepper
• 0.5 teaspoons Garlic powder
• 2 tablespoons Fresh parsley, chopped (optional for garnish)

Directions

Step 1

Preheat your oven to 375°F (190°C). Grease a 9x13-inch casserole dish lightly with butter or cooking spray and set aside.

Step 2

Peel the potatoes and slice them into thin rounds (about 1/4-inch thick). Set aside.

Step 3

Dice the ham into bite-sized pieces, and thinly slice the onion. Set both aside.

Step 4

In a medium saucepan, melt the butter over medium heat. Stir in the flour and cook for 1-2 minutes, whisking constantly, to form a roux.

Step 5

Gradually pour in the milk while whisking to combine. Continue cooking, stirring constantly, until the sauce thickens, about 3-5 minutes.

Step 6

Stir in the salt, black pepper, and garlic powder. Remove from heat and stir in 1 1/2 cups of the shredded cheddar cheese until it melts into a smooth sauce.

Step 7

Layer one-third of the potato slices evenly in the prepared casserole dish. Top with one-third of the ham and one-third of the sliced onion. Pour one-third of the cheese sauce over the layer.

Step 8

Repeat the layering process two more times, finishing with a generous layer of cheese sauce on top.

Step 9

Sprinkle the remaining 1/2 cup of shredded cheddar cheese evenly over the top of the casserole.

Step 10

Cover the dish with aluminum foil and bake in the preheated oven for 40 minutes.

Step 11

Remove the foil and bake for an additional 20 minutes, or until the top is golden and bubbly, and the potatoes are tender when pierced with a fork.

Step 12

Let the casserole rest for 5-10 minutes before serving. Garnish with chopped fresh parsley, if desired.
