Ingredients

Why this recipe works

The secret to this casserole lies in the balance of textures and flavors. Dicing the potatoes into uniform cubes ensures they cook evenly and absorb the rich flavors of the surrounding sauce.

As the casserole bakes, the starch from the potatoes naturally thickens the creamy sauce, creating a cohesive, velvety body that binds the ingredients together beautifully. Meanwhile, the savory, salty notes of the diced ham cut through the richness of the dairy, providing a delicious contrast in every single bite.

Baking the casserole uncovered allows the moisture to evaporate slightly, concentrating the flavors and helping the cheese top form a beautiful, golden-brown crust. The high heat melts the cheddar into stretching, gooey ribbons while crisping up the edges of the baking dish.

This dual texture—creamy and tender on the inside, with a bubbly, caramelized cheese layer on top—is what makes this traditional baking method incredibly successful and satisfying for any home cook looking for perfect results.

Notes and substitutions

For the best results, select firm potatoes like Russets or Yukon Golds, as they hold their shape well during the long baking process while releasing just enough starch to thicken the sauce.

Pre-cooked ham is ideal for this recipe; you can use leftover holiday ham or purchase thick-cut diced ham from the deli counter. Ensure the ham is dried slightly with a paper towel before adding it to the dish to prevent excess moisture from watering down your creamy sauce.

When it comes to the cheese, freshly shredded sharp cheddar is highly recommended over pre-packaged options. Pre-shredded cheese is often coated with anti-caking agents that prevent it from melting smoothly, which can result in a grainy texture. A standard glass or ceramic 9x13-inch baking dish is perfect for this recipe, as it distributes heat evenly and allows you to easily monitor the bubbling edges as the casserole cooks to golden perfection.

• diced cooked ham: cooked diced turkey or cooked crumbled bacon for a different savory profile
• shredded cheddar cheese: Gruyere, Swiss, or Monterey Jack cheese for a unique flavor twist
