In a deep-dish pie pan or square baking dish, whisk together eggs, milk, sugar, cinnamon, and vanilla.
Before you dredge the bread slices, preheat a large skillet or griddle over medium heat.
DREDGE BREAD SLICES:
Place the bread slices into the custard mixture and let them sit for 1 minute per side.
COOK THE FRENCH TOAST:
Cook each slice for 2-3 minutes per side, or until golden brown on each side.
KEEP THE TOAST WARM:
Place a wire rack inside a rimmed baking sheet and heat the oven to 275 degrees As slices of French toast finish cooking, place them in the baking sheet inside the oven until you are ready to serve.
TO FINISH:
Top slices with powdered sugar and drizzle with syrup (both optional).
Notes
If you’re using store-bought French bread, then soak the bread in the custard mixture for only 30 seconds per side.
