Recipe: Cheddar Cheese and Onion Pie

Cheddar Cheese and Onion Pie

6 to 8 servings (makes one 9-inch pie)

Thinly sliced apples lend a subtle sweetness to this savory pie, which can be served hot, warm or cold. And it's substitute-friendly: Pastry-challenged cooks can use a ready-for-baking pie crust, leeks instead of onions, and steamed diced potatoes instead of apple slices.

6 ounces (1 1/2 sticks) cold unsalted butter
