Ham, Potato, and Cheese Gratin

Yield 6-8 servings

Ingredients

Instructions

  1. In a saucepan over high heat, bring water to a boil. Add ¼-inch ham steaks or slices and simmer for 30 seconds. Remove from the heat, drain well, and set aside.
  2. Slice the potatoes thin, ⅛ inch thick; use a mandoline to produce even slices quickly.
  3. Simmer or parboil the potatoes until they are cooked half through; do this before layering them in the baking pan. (Simmering the potatoes will shorten the baking time.) Add seasonings to flavor both the potatoes and the liquid.
  4. Peel and smash garlic clove; rub the clove over the inside of the gratin dish (a 9-by-12-inch baking dish) then coat the inside of the dish with butter.
  5. Layer one-third of the potato slices evenly over the bottom of the buttered dish overlapping them slightly then season with salt, fresh ground pepper, and herbs. If you are substituting some of the potatoes with other thin sliced root vegetables such as parsnips or turnips—begin that now (but first parboil those vegetables as you did the potatoes).
  6. Add herbs and aromatic vegetables such as minced red onions or thin rounds of shallots or leeks atop the potatoes to evenly distribute the flavor.
  7. Next, layer half of the thinly sliced ham evenly over the potatoes. Again sprinkle herbs, salt and pepper, and add aromatic vegetables.
  8. Layer the potatoes again then add a second layer of ham before adding a final layer of evenly overlapping potatoes—even layers ensure even cooking.
  9. Preheat oven to 350°F.
  10. Pour the milk into a small saucepan and warm it over medium heat until small bubbles appear at the edge of the pan. Remove from the heat.
  11. In a medium saucepan melt the butter over medium heat. Stir in the flour and cook for 2 minutes stirring constantly; be careful not to brown the mix. Next, slowly stir in the hot milk and cook, stirring until the mixture thickens in about 4 to 5 minutes. Remove from the heat.
  12. Stir in the shredded cheese and mustard; season to taste with salt and black pepper. Return the saucepan to low heat and stir until the cheese just melts, 1 to 2 minutes.
  13. Pour the cheese sauce evenly over the layered potatoes and ham. Shake the pan gently to distribute the sauce evenly into the layers below. Bake uncovered until the potatoes are soft and easily pierced with a fork, the cheese is bubbling around the edges, and the top is golden brown, about 1 hour.
  14. Remove the gratin from the oven and let rest for 10 minutes allowing it to firm up. Serve directly from the gratin dish onto warmed plates. Serve with a green or bean salad and crusty bread or rolls.

Notes

The gratin can also be cooled and left at room temperature for several hours, and reheated in a moderate oven.
