Notes

  • Use day-old bread for the best texture and absorption.

  • Brioche or challah makes it extra rich and soft.

  • For a softer casserole, bake closer to 45 minutes; for firmer slices, bake longer.

  • Cover loosely with foil if the top browns too quickly.

  • Serve with maple syrup, powdered sugar, or fresh fruit.
