Our Best Christmas Breakfast Casserole Recipes

Hosting family and friends on Christmas morning? Then you’re going to need a few good breakfast or brunch recipes, espeically ones that can be made ahead. Quick breads and pastries are a good addition to any merry morning spread but we always make a point to prepare at least one breakfast casserole, too. They’re a great way to add something savory to the menu — and they go a long way. Plus, most can be prepared the night before, leaving you less to do on Christmas morning. Need a few good ideas to get you started? These are some of our favorite recipes.

Blueberry-Almond Croissant French Toast Casserole

We can’t think of a more delicious way to start off a wintery morning (or any kind of morning to be honest) than with a plate of this warm croissant French toast casserole. Day-old, store-bought croissants work perfectly for this, as their slight staleness helps them soak up all the creamy, almondy custard poured over top. Dollops of blueberry jam and a sprinkling of sliced almonds and fresh blueberries take it to another level, making it a decadent choice for breakfast, brunch or even dessert.
