Ingredients

Why this recipe works

The success of this casserole lies in the balance of moisture and starch. Diced potatoes release starch as they bake, which naturally thickens the creamy sauce into a luxurious, velvety consistency.

Covering the dish with foil during the first phase of baking traps the steam, ensuring that the potato cubes cook through completely and become tender without drying out or becoming mushy. This dual-stage baking method guarantees a perfect texture throughout the entire dish.

Additionally, baking the casserole uncovered in the final stage allows the excess moisture to evaporate while browning the cheddar cheese topping. This creates a beautiful contrast of textures, with a crispy, golden-brown cheese crust on top and a rich, creamy interior.

The savory ham pieces distribute their smoky oils throughout the bake, infusing every bite with deep flavor. It is a foolproof method that yields consistent, delicious results every single time.

Notes and substitutions

When choosing potatoes for this recipe, russet or Yukon Gold potatoes are the best options. Russets provide a fluffier texture and absorb the creamy sauce beautifully, while Yukon Golds offer a buttery flavor and hold their shape slightly better.

Be sure to dice them into uniform half-inch cubes to ensure even cooking. For the ham, pre-cooked diced ham from the grocery store is a great timesaver, but this recipe is also the perfect vehicle for using up leftover holiday ham.

For the best melting capability and flavor, grate your own cheddar cheese from a block rather than buying pre-shredded varieties. Pre-shredded cheese is coated with anti-caking agents that prevent it from melting smoothly, which can result in a grainy texture. Sharp cheddar provides a robust flavor that stands up well to the potatoes and ham, but you can easily substitute Gruyere, Swiss, or Monterey Jack for a different flavor profile.

• creamy sauce: A homemade béchamel sauce or a can of condensed cream of mushroom or chicken soup can be used as a convenient alternative.
• cheddar cheese: Colby Jack, Monterey Jack, or Gruyere cheese will melt beautifully and offer a delicious alternative flavor.
