Ingredients

Why this recipe works

The secret to the success of this casserole lies in the layering technique and the moisture balance. Slicing the potatoes thinly and evenly ensures they cook through at the same rate as the beef, absorbing the savory juices from the meat and tomatoes.

As the casserole bakes, the starch from the potatoes naturally thickens the creamy sauce, creating a rich, velvety consistency without the need for a complex roux or flour-based thickeners. This keeps the prep simple while delivering a luxurious texture.

Browning the ground beef first with the tomatoes develops deep, caramelized flavors that form the savory backbone of the dish. Cooking the meat beforehand also allows you to drain off excess grease, preventing the final casserole from becoming oily. When baked under a tight cover of foil, the steam cooks the potatoes to tender perfection, after which removing the foil allows the cheddar cheese to bubble and brown beautifully.

Notes and substitutions

For the best results, select starchy potatoes like Russets or Yukon Golds. Russets provide a soft, fluffy texture that absorbs the creamy sauce beautifully, while Yukon Golds offer a naturally buttery flavor and hold their shape slightly better.

A mandoline slicer is highly recommended to achieve uniform slices, which guarantees even cooking throughout the dish. If slicing by hand, use a sharp chef's knife and aim for slices about one-eighth of an inch thick.

When it comes to the cheese, shredding a block of sharp cheddar yourself is highly recommended over using pre-packaged shredded cheese. Pre-shredded varieties are coated with anti-caking agents that prevent them from melting smoothly, which can result in a grainy texture.

Freshly grated cheddar melts into a perfectly smooth, gooey layer that pulls beautifully when served. You can substitute the creamy sauce with a homemade blend of heavy cream or half-and-half if preferred.
