Ingredients

• 4 medium russet potatoes
• 4 tablespoons unsalted butter
• 3 tablespoons all-purpose flour
• 2.5 cups whole milk
• 0.5 cups heavy cream
• 2 cups sharp cheddar cheese, shredded
• 0.5 cups Parmesan cheese, grated
• 1.5 cups cooked ham, diced
• 6 large eggs
• 3 green onions, sliced
• 1 teaspoon garlic powder
• 1 teaspoon salt
• 0.5 teaspoon black pepper
• 0.5 cups breadcrumb topping (optional)
• 1 tablespoon olive oil or melted butter for topping (optional)

Directions

Step 1

Preheat your oven to 375°F (190°C) and lightly grease a 9x13-inch baking dish.

Step 2

Peel the potatoes and thinly slice them into uniform rounds, about 1/8-inch thick. Set aside in a bowl of cold water to prevent browning.

Step 3

In a medium saucepan, melt butter over medium heat. Sprinkle in the flour and whisk continuously for 1-2 minutes to cook out the raw flavor of the flour.

Step 4

Gradually add the milk and heavy cream, whisking constantly to combine. Cook for 3-5 minutes, until the mixture thickens and starts to bubble.

Step 5

Remove the saucepan from heat and stir in the cheddar cheese, Parmesan cheese, garlic powder, salt, and black pepper until the cheese has melted and the sauce is smooth.

Step 6

Drain the potatoes and pat them dry with a clean kitchen towel. Spread half of the potato slices in the bottom of the prepared baking dish, overlapping slightly.

Step 7

Sprinkle half of the diced ham and half of the green onions over the potatoes. Pour half of the cheese sauce evenly over the layer.

Step 8

Repeat with the remaining potatoes, ham, green onions, and cheese sauce, ensuring everything is evenly layered.

Step 9

Crack the eggs into small wells or divots made in the top layer of the casserole. Space them evenly, ensuring they remain intact.

Step 10

If using, mix the breadcrumbs with the olive oil or melted butter and sprinkle over the top of the casserole for an extra crispy finish.

Step 11

Cover the dish with foil and bake for 30 minutes. Remove the foil and bake for another 25-30 minutes, or until the eggs are set, the potatoes are tender, and the top is golden brown.

Step 12

Let the casserole rest for 10 minutes before serving. Sprinkle with extra green onions if desired.
