Ham & Potato Bake

This is leftover-ham territory at its most efficient. A quick stovetop cheese sauce of sharp cheddar and half-and-half gets stirred together with cubed ham, diced cooked potatoes, and chopped pimento, then baked covered until everything melds. Five ingredients, one casserole dish, no fussy roux or bechamel required.

Using aged sharp cheddar matters here. Mild cheddars turn rubbery when reheated and don’t carry enough flavor on their own. A really good aged cheese gives the sauce backbone, sharpness, and the kind of savory pull that makes a simple bake taste like more than the sum of its parts. The covered bake holds in steam and keeps the sauce from drying out or splitting during the 45-minute cook.

Kitchen Tips

• Stir the cheese sauce constantly over low heat. Cheese seizes and turns grainy at high temperatures, especially aged cheddar with low moisture.
• Use leftover boiled potatoes cooled completely. Hot potatoes break down into mush when stirred into the warm sauce.
• Cube the ham in bite-sized pieces. Long strands tangle on the fork and uneven sizes mean some pieces dry out.
• Don’t peek during baking. Lifting the cover lets steam escape and the top crusts over instead of staying creamy.

Variations

• Stir in a handful of frozen peas or chopped broccoli for color and a vegetable boost.
• Swap turkey ham for diced cooked chicken for a tetrazzini-leaning version.
• Top with crushed buttery crackers or panko breadcrumbs in the last 15 minutes for a crisp golden lid.
