Ingredients

Why this recipe works

The secret to this casserole's incredible texture lies in the balance of moisture and heat during the baking process. Baking the dish covered with foil for the first phase traps the steam escaping from the potatoes, allowing them to cook thoroughly and become tender without drying out.

This steaming process also helps the starch from the potatoes meld with the cream sauce, naturally thickening it into a luxurious glaze that clings to every ingredient rather than pooling at the bottom.

Additionally, using a prepared cream sauce ensures a stable base that will not break or curdle under high oven heat. The sharp cheddar cheese is divided, with half folded into the sauce to create a cohesive, cheesy body throughout the dish, and the other half melted on top during the final minutes of baking. This dual-cheese approach ensures gooey goodness in every single bite.

Notes and substitutions

When choosing potatoes for this recipe, Russet potatoes are excellent because their high starch content helps thicken the sauce, but Yukon Gold potatoes are a fantastic alternative if you prefer a creamier, more buttery texture that holds its shape.

For the ham, this is an exceptional way to repurpose leftover holiday ham, but thick-cut deli ham or pre-packaged diced ham from the grocery store works perfectly well. Just ensure the ham is fully cooked before adding it.

For the best cheese pull and flavor, buy a block of sharp cheddar and shred it yourself rather than buying pre-shredded bags. Pre-packaged cheese is coated with anti-caking agents like potato starch, which can prevent it from melting smoothly and leave your sauce with a slightly grainy texture.

Standard glass or ceramic baking dishes work best for this recipe because they distribute heat evenly and prevent the bottom from burning.

• cream sauce: A homemade white sauce or a can of condensed cream of potato soup can be used as a convenient alternative.
• potatoes: Yukon Gold potatoes work wonderfully and hold their shape well while providing a buttery texture.
