12 ounces French bread – cut into 1-inch thick slices
3 tablespoons unsalted butter
1 tablespoon vegetable oil
powdered sugar – for dusting (for serving)
cane syrup – for serving
Instructions
Slice the French bread into 1-inch thick slices and set aside; day-old bread is ideal so it soaks without falling apart.
In a wide, shallow bowl, whisk the eggs, granulated sugar, kosher salt, ground cinnamon, and ground nutmeg until smooth.
Whisk in the whole milk, heavy cream, and vanilla extract until the custard is evenly combined and fluid.
Lay the bread slices in a single layer in the custard. Soak 2–3 minutes per side, turning once, until the slices are saturated but still hold their shape.
Heat a large nonstick skillet or griddle over medium heat. Melt 2 tablespoons unsalted butter with the vegetable oil.
Lift each soaked slice, let excess custard drip back into the bowl, and place it in the hot pan. Cook until deep golden and the custard is set in the center, 3–4 minutes per side; lower the heat to medium-low if it browns too quickly.
Repeat with the remaining bread, adding the remaining 1 tablespoon butter to the pan between batches as needed.
Dust the pain perdu with powdered sugar and serve hot with cane syrup.
