Creamy ham and scalloped potatoes cheesy, hearty, and oven-baked to golden perfection. The ultimate winter comfort food casserole.

Ingredients

For the Creamy Sauce:

  • 4 tablespoons butter
  • 4 tablespoons all-purpose flour
  • 3 cups milk
  • Salt & pepper to taste

For the Layers:

  • 1 tablespoon butter for sautéing onions
  • 3 medium yellow onions thinly sliced
  • 8 medium russet potatoes peeled and thinly sliced (use a mandoline if you have one!)
  • 24 oz sliced ham about 2 thick ham steaks, cubed
  • 4 cups freshly grated mild cheddar cheese

Instructions

Step 1: Preheat Your Oven

  • Set your oven to 350°F (175°C). Lightly butter a deep 9x13-inch baking dish to prevent sticking and to add a bit of flavor.

Step 2: Make the Creamy White Sauce

  • In a saucepan over medium heat, melt 4 tbsp of butter.
  • Whisk in the flour to form a roux. Cook for 1 minute, stirring constantly.
  • Remove from heat and slowly whisk in the milk until smooth.
  • Return to heat and simmer, whisking, until thickened—about 5–7 minutes.
  • Season generously with salt and pepper. Set aside.

Step 3: Sauté the Onions

  • In a large skillet, melt 1 tablespoon butter over medium heat.
  • Add sliced onions and cook for 10–12 minutes, until golden and soft.
  • Season lightly with salt and pepper.

Step 4: Layer the Casserole

  • Now comes the fun part:
  • Spread 1/3 of the white sauce in the bottom of your prepared baking dish.
  • Layer with:
  • Half of the sliced potatoes
  • Half of the sautéed onions
  • Half of the cubed ham
  • Half of the shredded cheese
  • Pour another 1/3 of the white sauce evenly over the top and season lightly.
  • Repeat the layers with the remaining ingredients, finishing with the remaining cheese on top.

Step 5: Bake to Golden Perfection

  • Cover with foil and bake for 45 minutes.
  • Remove the foil and continue baking for 30–40 more minutes, or until the potatoes are fork-tender and the top is bubbly and golden.

Step 6: Let it Rest

  • Remove from the oven and let the casserole rest for 10 minutes before slicing. This helps it set and makes it easier to serve.
