Step-by-Step Guide to Making Your Eggnog Breakfast Casserole

1. Make the Eggnog Custard Mixture

  • In a large bowl, whisk together:
    • 2 cups of eggnog
    • 4 large eggs
    • 1/4 cup granulated sugar
    • 1 teaspoon vanilla extract
    • 1 teaspoon ground cinnamon and 1/4 teaspoon nutmeg
  • Mix until smooth, ensuring all spices are evenly distributed.

2. Prepare the Bread

  • Cut your bread into 1-inch cubes for even soaking.
  • Arrange the cubes in a greased 9×13 baking dish.
  • Pour the eggnog mixture evenly over the bread, ensuring each piece is coated.

Tip: Let the bread sit for a few minutes to absorb the custard before covering.

3. Cover and Refrigerate Overnight

  • Cover the dish tightly with plastic wrap.
  • Refrigerate for at least 8 hours or overnight to allow the flavors to meld.

4. Add Toppings and Bake

  • Preheat your oven to 350°F (175°C).
  • If using a streusel topping, mix together 1/2 cup brown sugar, 1/4 cup flour, 1/4 cup cold butter, and a pinch of cinnamon. Sprinkle it evenly over the casserole.
  • Bake uncovered for 45-50 minutes until golden brown and set in the center.

Shortcut: Skip the streusel and drizzle maple syrup directly before serving.

Creative Serving Suggestions

Take your casserole to the next level with these ideas:

  • Pair it with crispy bacon or sausages for a savory contrast.
  • Serve alongside fresh fruit like sliced oranges or berries for a refreshing balance.
  • Offer a variety of syrups, including classic maple, caramel, or spiced honey.

Tips for Perfect Results

  • Use Stale Bread: Slightly dry bread absorbs the custard better without becoming soggy.
  • Adjust the Sweetness: Taste your eggnog before adding sugar to balance sweetness levels.
  • Add Alcohol (Optional): A splash of rum or bourbon can elevate the holiday flavors for adult gatherings.
  • Keep an Eye While Baking: Cover with foil if the top browns too quickly.
