Ingredients

Why this recipe works

The success of this casserole lies in the balance of textures and the structure of the cheese sauce. Using a pre-made or store-bought cheese sauce ensures a smooth, stable base that will not split or become greasy during the baking process.

This velvety sauce perfectly coats every cube of potato and piece of ham, ensuring that no bite is left dry or unseasoned while creating a cohesive, comforting texture throughout the entire dish.

Pre-cooking the cubed potatoes slightly before combining them with the other ingredients is another crucial step. Potatoes contain a high amount of water, and baking them completely raw in a sauce often results in an overly watery casserole or unevenly cooked pieces.

A quick parboil locks in their shape while allowing them to release excess starch, which actually helps the cheese sauce cling to them even better as the dish bakes to its final bubbly state.

Notes and substitutions

For the best results, select starchy or all-purpose potatoes like Russets or Yukon Golds. Yukon Golds offer a naturally buttery flavor and hold their shape well, while Russets provide a fluffier texture that absorbs the cheese sauce beautifully.

When it comes to the cheese topping, grating a block of sharp cheddar yourself is highly recommended. Pre-shredded packaged cheeses are coated with anti-caking agents that prevent them from melting smoothly, which can lead to a slightly grainy texture.

The ham should be fully cooked and diced into uniform bite-sized pieces to match the size of the potato cubes. Leftover baked ham works wonderfully here, but thick-cut deli ham or a pre-packaged ham steak from the grocery store is also an excellent option. For the sauce, select a high-quality store-bought cheese sauce or prepare your favorite recipe ahead of time to keep the assembly quick and effortless.
