Ingredients
- 4 medium-sized russet potatoes
- 2 cups cooked ham
- 1 large yellow onion
- 2 cups shredded cheddar cheese
- 1.5 cups milk
- 3 tablespoons unsalted butter
- 2 tablespoons all-purpose flour
- 1 teaspoon garlic powder
- 1 teaspoon salt
- 0.5 teaspoon ground black pepper
- 2 tablespoons parsley
- 2 tablespoons olive oil
Directions
Step 1
Preheat your oven to 375°F (190°C). Lightly grease a 9x13-inch baking dish with cooking spray or butter.
Step 2
Peel the potatoes and slice them into thin rounds, approximately 1/8-inch thick. Set them aside in a bowl of cold water to prevent browning.
Step 3
Dice the cooked ham into small, bite-sized pieces. Set aside.
Step 4
Slice the yellow onion thinly. In a skillet, heat the olive oil over medium heat. Add the onion slices and cook for 7-8 minutes, stirring occasionally, until they are softened and lightly caramelized. Set aside.
Step 5
In a medium saucepan, melt the butter over medium heat. Once melted, whisk in the flour and cook for 1 minute to form a roux.
Step 6
Slowly pour in the milk while continuously whisking to avoid lumps. Cook for 3-4 minutes, or until the sauce thickens slightly.
Step 7
Stir the garlic powder, salt, black pepper, and half of the shredded cheddar cheese (1 cup) into the sauce. Mix until the cheese is fully melted and the sauce is smooth. Remove from heat.
Step 8
Drain the potatoes and pat them dry with a clean kitchen towel. Begin layering the casserole: start with a single layer of potato slices on the bottom of the prepared baking dish.
Step 9
Top the potato layer with a portion of the ham, caramelized onions, and a drizzle of the cheese sauce. Repeat the layers until all ingredients are used, finishing with a layer of cheese sauce on top.
Step 10
Sprinkle the remaining cheddar cheese (1 cup) evenly over the casserole.
Step 11
Cover the baking dish with aluminum foil and bake in the preheated oven for 40 minutes. Then, remove the foil and bake for an additional 20 minutes, or until the top is golden and bubbly and the potatoes are tender.
Step 12
Remove the casserole from the oven and let it rest for 5-10 minutes before serving. Garnish with freshly chopped parsley for added flavor and presentation.
