French Toast Casserole

This baked French toast casserole is one of the easiest recipes you will ever make! I love it not only because it’s totally decadent and delicious but it requires zero sit time - don’t get me wrong I love a good overnight French toast casserole but sometimes you just want it now and this is THAT French toast casserole! Seriously decadent right out of the oven, crispy edges soft middle texture with its self saucing caramel sauce at the bottom - oh my!! I love to serve it with whipped cream and chopped nuts or fresh berries or other fruit - and for extra decadence drizzled of maple syrup. It the perfect breakfast casserole for brunches or slow morning when you are craving something sweet and delicious!

French Toast Casserole Recipe Ingredients

  • BREAD: You are going to need a fairly large loaf of bread – enough to make about 6-7 cups once cubed. Use any loaf, like a French loaf, sourdough bread for a tighter sturdier crumb or ciabatta, challah or torn or cubed Texas toast for a softer lighter crumb which will soak up the custard faster. Feel free to use glute free bread if needed
  • BUTTER: I use unsalted and for this recipe it is melted or browned - I love to use brown butter for this recipe as it gives this French toast casserole even more flavor.
  • SUGAR: You will need brown sugar for the casserole and granulated sugar for the cinnamon sugar topping.
  • EGGS: You will need 6 large eggs. Eggs help bind everything together.
  • MILK: I recommend whole milk or even a combination of whole milk and heavy cream for a richer custard
  • RUM/BOURBON: The bourbon is optional but it adds such a delicious flavour to the custard and overall dish. I often swap it out for spiced rum too. If you prefer the recipe without alcohol - simply replace it with more milk.
  • VANILLA: Adds that signature flavor to all my sweet baked goods.
  • SPICES: I kept things simple with cinnamon and a pinch of salt but feel free to add more warming spices like nutmeg, cardamon or allspice.

Baked French Toast Casserole Make Ahead

  • MAKE AHEAD: This baked French toast can be made ahead so it’s more of an overnight French toast. Prepare as directed up to when you have to bake it then cover casserole dish with plastic wrap and store in the fridge overnight. When ready to bake remove from fridge and let it sit on the counter while you preheat the oven, uncover the plastic wrap and bake as directed.
  • STORAGE: Leftovers can be covered tightly and stored in the refrigerator for up to 4-5 days. To reheat, place in a preheated oven at 350°F for 10 to 15 minutes, or until warmed through and re-crisped on top. Slices can be reheated in the microwave or toaster oven.
  • FREEZING: The fully cooked and cooled casserole can be frozen, although it’s better when fresh. But if you have leftovers to freeze, wrap individual portions in plastic wrap and then a layer of foil. Defrost the individual slices in the refrigerator overnight then reheat until just warmed through in the microwave or oven. If you are freezing the whole casserole wrap in plastic wrap and foil and place cooled casserole in the freezer and store for up to 1 month - thaw in the fridge overnight and place in a preheated oven at 350°F for 10 to 15 minutes, or until warmed through and re-crisped on top.

Recipe Notes

  • For less custardy cover with foil at the 20 minute mark and continue to cook a few extra minutes until cooked to your desired texture
  • Instead of pouring the custard over the bread cubes in the casserole dish, feel free to mix or toss the bread cubes and the custard together in a bowl first to saturate all the cubes with the custard.
  • No one likes soggy bread! French toast casserole is one of those recipes that has a lot of variables. Maybe your eggs are a bit bigger, or your bread was too fresh etc. There’s an easy way to fix soggy French toast, though. Just increase your baking time until the casserole has reached your desired level of doneness. Cover loosely with foil to prevent top from burning or browning too quickly.
