Instructions

  1. Step 1: Grease a 9x13-inch baking dish with 1 tbsp unsalted butter. Spread 8 cups of cubed thick-cut brioche bread evenly in the dish.
  2. Step 2: In a large mixing bowl, whisk together 2 cups eggnog, 6 large eggs, 1/2 cup granulated sugar, 1 tsp ground cinnamon, 1/2 tsp ground nutmeg, and 1 tsp pure vanilla extract until smooth and fragrant.
  3. Step 3: Pour the eggnog mixture evenly over the bread cubes, pressing gently with a spatula to make sure all bread is soaked. Drizzle 1 tbsp melted unsalted butter over the top.
  4. Step 4: Cover tightly with plastic wrap and refrigerate overnight (at least 8 hours) to allow the bread to absorb the custard.
  5. Step 5: Preheat oven to 350°F. Remove plastic wrap and bake uncovered for 45-50 minutes until the top is golden and the custard is set.
  6. Step 6: Let cool for 10 minutes before serving. Serve warm with maple syrup on the side.
