Generously cover potatoes with cold water in a 4-quart pot and add 1 tablespoon salt. Bring to a boil, then simmer, partially covered, until potatoes are just tender when pierced with a small sharp knife, about 12 minutes. Drain. Cool potatoes to warm, then peel and cut in half crosswise.

Brush bottom of a 15- by 10-inch shallow baking pan with oil and half of reserved bacon fat. Sprinkle potatoes with 1/2 teaspoon salt and 1/4 teaspoon pepper and arrange, cut sides down, in baking pan. Bake until undersides are golden brown, 30 to 35 minutes.

Reduce oven temperature to 375u00b0F. Turn potatoes over, then sprinkle with cheese, bacon, and garlic and drizzle with remaining bacon fat (if fat congeals, reheat briefly over medium heat). Bake until cheese is melted, about 15 minutes. Sprinkle with parsley.

Cook's notes:
-
7
Potatoes can be boiled and peeled 1 day ahead and chilled in an airtight container.
-
8
Potatoes, without cheese, bacon, garlic, and bacon fat, can be baked 6 hours ahead and kept, loosely covered, at room temperature. Turn potatoes over and proceed with recipe, baking a little longer. If baking at same time as stuffing, leave oven temperature at 425u00b0F.
