If you're used to having visitors spend the night at your house, you're familiar with hectic times in the kitchen, trying to feed an army of people. Baked casseroles, sweet or savory, are great options for large groups of people because they go a long way when served with fruit and spreads (or a small cheese plate), are easy to prep, and there won't be much to clean after, besides your guests empty plates.

This overnight French toast casserole is especially convenient since it can be prepared the night before and then baked in the morning. You might also like New Orleans Style French Toast or pain perdu, or a different French toast flavor like in our vanilla version.

Glass Bakeware Warning

For premade casseroles or leftovers that are in a glass baking dish and have been refrigerated, do not place directly into a hot oven as the glass can shatter. Instead, place any cold glass bakeware into a cold oven to warm up while it preheats. Or, allow the bakeware to rest outside of the fridge for 30 minutes to reach room temperature while the oven preheats.

Toppings for Your Toast

French toast is a great brunch dish and can be the centerpiece of an even tastier spread by using one of the following variations:

  • Sweet Savory Toast: Follow the recipe to the letter and while the toast bakes, pan-fry 12 slices of bacon until crispy. Discard the fat. Serve each portion of toast with 2 strips of bacon and extra maple syrup on the side.
  • Chocolate Toast: Follow the recipe to the letter and 5 minutes before the end of the cooking time, sprinkle 1 cup of semi-sweet chocolate chips on top of the toast. Finish baking and serve each slice with freshly cut strawberries.
  • Croque Madame Toast: Follow the recipe to the letter and bake the toast in two separate pans, dividing the bread evenly into the pans. Once the slices of French toast are cooked, take both pans out of the oven and top one of the pans with 1 layer of sliced Gruyere cheese and 1 layer of good quality ham. Cover the toast that has the ham and cheese with the undressed slices, making sandwiches, and bake for an additional 5 to 7 minutes. While they bake crack open 6 eggs and fry them. Top the French toast Croque Madames with a fried egg each.

Raw Egg Warning

Consuming raw and lightly-cooked eggs poses a risk of food-borne illness.
