6 large eggs Provides structure and richness.

2 cups eggnog (store‑bought or homemade) Adds holiday spice; substitute milk + ½ tsp nutmeg.

½ cup heavy cream Creates extra fluffiness.

¼ cup pure maple syrup For the glaze; extra for serving.

2 tbsp unsalted butter, melted Adds richness to the custard.

1 tsp vanilla extract Enhances overall flavor.

½ tsp ground nutmeg Classic eggnog spice.

¼ tsp ground cinnamon Adds warmth.

Instructions

Prepare the custard

In a large bowl whisk eggs, eggnog, heavy cream, melted butter, vanilla, nutmeg, and cinnamon until smooth. The mixture should be slightly frothy, indicating air incorporation for a fluffy texture.

Pro Tip: Whisk gently to avoid over‑beating; you want a uniform blend, not a tough batter.

Soak the bread

Arrange cubed brioche in a greased 9‑x 13‑inch baking dish. Pour the custard evenly over the bread, pressing gently to ensure every piece is saturated. Cover and refrigerate for at least 8 hours or overnight.

Pro Tip: If you’re short on time, a 2‑hour soak works, but overnight yields the fluffiest result.

Add the maple glaze

Drizzle ¼ cup maple syrup over the soaked bread, allowing it to pool in the corners. The syrup will caramelize during baking, creating a glossy, sweet crust that complements the spice.

Pro Tip: Use dark, grade‑A maple for a richer flavor profile.

Bake to golden perfection

Preheat oven to 350°F (175°C). Bake the casserole uncovered for 35‑40 minutes, or until the top is deep golden and a knife inserted in the center comes out clean.

Pro Tip: If the top browns too quickly, loosely tent foil over the dish after 20 minutes.

Serve with extra maple syrup

Allow the casserole to rest five minutes, then cut into squares. Drizzle additional warm maple syrup over each serving and garnish with a dusting of cinnamon or fresh berries, if desired.

Pro Tip: Warm the extra syrup briefly to keep the glaze glossy.

Expert Tips

Tip #1: Use Day‑Old Bread

Stale bread absorbs more custard without becoming mushy, giving each bite a tender yet structured crumb.

Tip #2: Chill Overnight

Refrigerating the assembled casserole allows the flavors to meld and the custard to fully penetrate the bread.

Tip #3: Add a Crunch

Scatter a handful of chopped pecans or toasted pumpkin seeds on top before baking for texture contrast.

Tip #4: Serve Warm

The casserole is best enjoyed immediately; reheating gently in a low oven restores its fluffy interior.
