Instructions
Heat oven to 375ºF. Line a 9x13x2-inch baking dish with parchment.
Whisk eggs in a large bowl. Whisk in milk, cream, maple syrup, vanilla, cinnamon, and salt until smooth.
Dip each slice of bread into the custard, then shingle the slices in the dish so they slightly overlap and absorb more custard. Pour any remaining custard over the top.
Drizzle melted butter over the bread.
Bake until puffed, edges are crisp, and center is set, about 30 minutes. The internal temperature at the center should read about 175ºF. Let stand 5 minutes before serving.
Notes
If your bread is fresh, dry slices in a 300ºF oven for 8–10 minutes.For doneness, target an internal temp of 175–180ºF (79–82ºC). At this range the eggs are fully set but the middle stays creamy. If it’s under 170ºF, it will be too loose and won’t hold once cooled.Overnight option: assemble, cover tightly, and refrigerate overnight. Bake at 375ºF for about 35 minutes, until golden and set. Let stand 5 minutes before slicing.
