Method
- In a medium saucepan over medium heat, melt the butter. Whisk in the brown sugar and maple syrup until smooth. Pour into a 9x13 inch baking dish.
- Arrange the thick slices of stale brioche bread in a single layer over the caramel mixture, squeezing them to fit.
- In a large bowl, whisk together the eggs, half-and-half, vanilla extract, Grand Marnier (if using), and salt until well combined.
- Pour the custard mixture evenly over the bread slices. Press down lightly to help the bread absorb the liquid.
- Cover the dish tightly with plastic wrap and refrigerate overnight (or at least 8 hours).
- The next morning, remove the dish from the fridge and let it sit at room temperature for 30 minutes. Preheat your oven to 350°F (175°C).
- Bake uncovered for 35-45 minutes until puffed, golden brown, and the caramel is bubbling around the edges.
- Serve immediately by scooping out a slice and inverting it onto a plate so the caramel side is up. Dust with powdered sugar.
Notes
If the top is browning too quickly while baking, tent lightly with aluminum foil for the last 10-15 minutes.
