As you all know quick and easy is my way! I love breakfast, especially overnight breakfast casseroles. As much as I love serving it at breakfast time, it also makes a great dinner! It’s so easy to whip up that it makes a perfect dinner and it’s delicious!

Plus, it’s fun to do it at night for mixing things up and being in a rut is not what we want right?!

My kids love it, which is always a win. In fact when I served this my oldest daughter ate three pieces and was begging for it for snack before bedtime. I cut her off, but I promised to warm her up a piece for breakfast the next morning. It reheats great which is another plus!

My family LOVED this Overnight French Toast Casserole. I couldn’t believe my oldest child and her obsession. She’s begging for it every night now!

If you want to serve breakfast for dinner this is the perfect recipe. Whip it up the night before or in the morning before you go to work and pop it right into the oven when you get home.

Expert Tips

• The best bread to use for French Toast is sourdough, challah, brioche and French bread. For this recipe I like sourdough. It holds up nicely and bakes perfectly delicious!
• Prepare this casserole the night before you want to enjoy it because it gives the bread time to soak up the egg mixture. You’ll want to let it soak at least 3-4 hours.
• If it comes out soggy, the bread you used might not have been hearty enough to soak up the egg mixture. Try using a more hearty bread next time or reducing the amount of milk.
• Topping ideas including whipped cream, fresh berries, maple syrup and butter.
• To reheat leftovers, cover the dish with tin foil and tuck it back into the oven for about 30 minutes or until it’s hot – you’ll know when it’s done because you can smell the deliciousness! It will be best to reheat it in the oven, though you can certainly pop it in the microwave in a pinch.

Ok – are you ready to make this easy recipe? I bet you are! This meal is perfect for breakfast, lunch or brunch! And as I’d mentioned earlier, my daughter ate it for dinner too – it’s a favorite! Easy to make and simply delicious!

Your family or guests will be so impressed when you whip this out of the fridge in the morning, bake it to perfection and spoil them!
