ATK Cast Iron French Toast Casserole

French toast is a delicious, easy-to-make breakfast favorite, but could we make it even easier—and more crowd friendly? To meet our goal, we translated the concept of French toast into a casserole. No more standing at the stove, flipping slice after slice, dripping egg wash on the counter, or serving one person at a time: Our French toast casserole is an ideal family breakfast. It takes full advantage of the cast-iron skillet's heat-retaining ability to replicate the crisp-crusted texture of conventional French toast in a simple, family-size dish. Potato bread, with its sturdy slices, was the perfect choice for the base of our casserole. To ensure that the bread would fit easily in a skillet, we halved the slices and layered them in the pan with a brown sugar–cinnamon mixture and butter. Repeating this process to create a double stack, we then poured egg custard over the top so it could soak through the layers of bread. For a satisfying crunch, we topped the casserole with sliced almonds before putting it into the oven and finished the baked casserole with a light dusting of confectioners' sugar. The result? A cast-iron skillet filled with layers of tender, sweet French toast.
