Instructions
Step 1 — Make the Caramel Layer:
Melt the butter in a saucepan over medium heat. Stir in the brown sugar and corn syrup until the mixture becomes smooth and fully combined. Pour this into a 9×13 inch baking dish.
Step 2 — Layer the Bread:
Arrange the sliced bread in a single layer on top of the caramel mixture.
Step 3 — Mix the Custard:
Whisk together the eggs, half-and-half, vanilla, Grand Marnier (if using), and salt until smooth.
Step 4 — Soak Overnight:
Pour the custard evenly over the bread and lightly press so it absorbs the mixture. Cover and refrigerate for at least 8 hours or overnight.
Step 5 — Bake:
Preheat the oven to 350°F (175°C). Remove the dish from the fridge while the oven heats, then bake for 35–40 minutes, or until golden and puffed.
Step 6 — Finish & Serve:
Allow it to rest briefly before serving. For a true crème brûlée touch, sprinkle sugar over the top and caramelize with a kitchen torch until crisp and golden.
