A rich and creamy holiday breakfast casserole made with brioche, eggnog, and warm spices. This easy-to-make dish is perfect for Christmas morning or festive brunches, offering a comforting balance of crispy top and custardy interior.
Day-old brioche or challah works best as it absorbs the custard without becoming mushy. If the top browns too quickly, cover loosely with foil for the last 10 minutes. For a dairy-free version, substitute heavy cream with coconut cream and butter with coconut oil. For gluten-free, use gluten-free brioche but reduce soaking time as it absorbs liquid faster.
