 Preparation & Cooking Time

  • Cooking Time: 45 minutes
  • Total Time: ~1 hour 5 minutes
  • Servings: 6

 Ingredients

For the casserole:

  • 3 cups cooked ham, diced (perfect for leftovers)
  • 4 medium potatoes, peeled and sliced thin
  • 1 small onion, diced
  • 2 cloves garlic, minced
  • 3 tablespoons butter
  • 3 tablespoons all-purpose flour
  • 2 1/2 cups milk (whole milk recommended)
  • 1/2 teaspoon Dijon mustard (optional for depth of flavor)
  • 1/2 teaspoon paprika
  • Salt and black pepper, to taste
  • 2 cups shredded cheddar cheese (divided)
  • 1/4 cup Parmesan cheese
  • 2 tablespoons fresh parsley, chopped (optional garnish)

 Instructions

Step 1: Prepare the Cheese Sauce

  1. In a medium saucepan, melt the butter over medium heat.
  2. Add the flour and whisk for about 1–2 minutes to form a smooth roux.
  3. Slowly pour in the milk, whisking continuously until the mixture thickens into a creamy sauce.
  4. Stir in the Dijon mustard, paprika, salt, and pepper.
  5. Add 1 1/2 cups of cheddar cheese, whisking until fully melted and smooth. Set aside.

Step 2: Assemble the Casserole

  1. Preheat oven to 375°F (190°C).
  2. Grease a 9×13-inch baking dish.
  3. Layer half of the sliced potatoes on the bottom of the dish.
  4. Add half the ham and onions, then pour some of the cheese sauce over the top.
  5. Repeat with the remaining potatoes, ham, onion, and sauce.
  6. Sprinkle the remaining cheddar cheese and Parmesan evenly on top.

Step 3: Bake

  • Cover the dish with aluminum foil and bake for 30 minutes.
  • Remove the foil and bake for an additional 15 minutes, until the top is golden brown and bubbly.
  • Let the casserole rest for 5–10 minutes before serving so it sets nicely.

 Tips & Variations

  • Veggie Add-ins: Add peas, broccoli, or spinach for extra nutrition and color.
  • Creamier Texture: Substitute half of the milk with heavy cream for a richer casserole.
  • Cheese Options: Experiment with Gruyère, Monterey Jack, or mozzarella instead of cheddar.
  • Spicy Kick: Add chopped jalapeños or a pinch of cayenne pepper for a little heat.
  • Crunchy Topping: Mix breadcrumbs with melted butter and sprinkle over the top before baking for added crunch.
  • Gluten-Free: Use cornstarch instead of flour to thicken the sauce and ensure gluten-free ingredients throughout.

 Serving Suggestions

  • Pair with a crisp green salad for a balanced meal.
  • Serve alongside roasted vegetables like carrots or Brussels sprouts.
  • Enjoy it as a hearty brunch dish with a fried egg on top.
  • Perfect as a standalone comfort food dinner on chilly nights.

 Storage & Make-Ahead

  • Refrigerator: Store leftovers in an airtight container for up to 3 days. Reheat in the oven or microwave.
  • Freezer: Freeze the casserole (either baked or unbaked) for up to 2 months. Thaw overnight in the fridge before reheating or baking.
  • Make-Ahead: Assemble the casserole a day in advance, cover tightly, and refrigerate. Bake just before serving.
