Overnight French Toast Casserole Recipe

French toast is one of my favorite breakfasts, hands-down. I tend to save it for special occasions like Mother's Day or Thanksgiving morning, but as my family kept growing, so did the portion sizes!

After years of making french toast, I decided to give breakfast casserole french toast a try! Let me tell you, I've never seen breakfast disappear so fast. I wanted to have leftovers, but I had to make another entire casserole the same day! Thankfully, it's all the flavor with half the work!

It didn't take long for me to learn to make it the day before. Making this casserole french toast overnight saves you all that morning prep, making a big breakfast easy as can be! Not feeding a whole family? Prepare for days of easy breakfasts!

Sooooooo good I made it for my husband and I the last time you shared & we had breakfast for like 4 days

Overnight French Toast Ingredients

• Brioche or Challah bread: I highly recommend a sweet loaf like Brioche or Challah! I used one with chocolate chips and it was to die for. If you want a more complex flavor, try using sourdough bread!
• Butter: Butter, combined with brown sugar, makes a delicious caramel-y base for this french toast that leaves it crispy, chewy, and utterly decadent.
• Brown sugar: It's important to use brown sugar, not white sugar. The molasses will help pair with the butter for a richer, more delicious caramel sauce.
• Eggs: Any large eggs work, but as always, I really recommend pasture-raised eggs. They just taste better!
• Milk: I recommend whole milk, which thickens up and has a lovely flavor in comparison to skim milk. You can also use half & half.
• Vanilla extract: For a sweet baked french toast casserole, I recommend vanilla extract! However, I've used pumpkin pie extract and almond extract before, and both were delightful.
• Cinnamon: A pinch of cinnamon adds a wonderful aroma and hint of spice that French Toast just isn't right without!
• Powdered sugar (optional): Personally, I like adding a dusting of powdered sugar to the top after it's done baking. It's just so pretty!
• Fresh berries (optional): You can mix them into the casserole before baking (ever tried blueberry french toast casserole?), or add them to the top afterwards for a fresh burst of juicy goodness!

Overnight French Toast Casserole Recipe

1. Preheat oven to 425°F. Butter a 9 by 13-inch baking dish and cut or tear your bread loaf into cubes.
2. In a saucepan over medium heat, melt the butter. Add brown sugar and mix well until the sugar dissolves completely and the mixture is smooth and beginning to thicken.
   
3. Pour the mixture into the bottom of your greased baking dish. Smooth out evenly across the bottom of the dish.
   
4. Add bread cubes to the baking dish.
   
5. In a bowl, whisk together eggs, milk, vanilla, and half of your cinnamon. Once whisked well, pour egg mixture over the cubed bread. Make sure all pieces of bread have been soaked. Mix together remaining cinnamon and sugar to make cinnamon sugar, then sprinkle over the loaf.
   
6. Bake 25-30 minutes, or until the top is golden brown and fluffy. Remove from the oven and top with powdered sugar and fresh fruit if desired. Enjoy!

Making Make-Ahead French Toast Casserole

Making this casserole ahead of time is super simple. All you need to do is fully assemble it following the directions above, then wrap it in plastic wrap and place it in the fridge before baking it. It will continue to soak up flavor overnight!

On the morning you wish to serve it, bake it as usual straight out of the oven, then dig in! This is the perfect breakfast recipe for holidays!

Make Ahead French Toast Casserole Tips

• If your casserole is browning too quickly, cover it with foil for part of the cooking time.
• I recommend using brioche or challah bread for this recipe, or a nice thick sourdough. Avoid regular sliced white bread; it's so thin and airy, it will just turn to mush.
• 1-2 days old bread works best for French toast as it holds up better to the liquid. If you're using a fresh loaf, just leave the loaf out, unwrapped, for 1-2 hours. You can even speed up the process by tearing it into cubes and leaving them out for 30 minutes.
• If you want to avoid dairy milk, you can use almond, oat, or coconut milk instead.

Overnight Casserole French Toast Variations

• Savory: Add in cubed ham, bacon, or even a sprinkling of cheese on top for savory french toast. You can cut back on the sugar or embrace the sweet and savory!
• Orange: Orange pairs wonderfully with maple and caramel, so a great variation is adding orange zest to the milk and egg mixture!
• Blueberry: Mix in fresh blueberries with the bread chunks for blueberry french toast! You can also use frozen, but I recommend rinsing off any stuck-on ice and then dusting them in flour before adding them in.
• Pumpkin: Pumpkin french toast casserole is the perfect Autumn treat! To make it, mix in a can of pumpkin puree into the milk and egg mixture, and use pumpkin pie spice instead of cinnamon.
• Eggnog: This is the Christmas breakfast recipe you've been waiting for! Swap out the milk for eggnog and add a bit of nutmeg to the seasonings for this holiday classic.

French Toast Casserole FAQs

How to Store French Toast Casserole

• Fridge: Casserole french toast can be stored in the fridge for 5 days. I usually keep it in the casserole dish until only a few servings are left, at which point it can be moved to airtight containers. This makes it a great breakfast for the whole week.
• Freezer: Leftover casserole can easily be frozen in serving-sized containers, but only after it's been baked. You can also cover the entire casserole dish in plastic wrap and freeze it that way.
• Thawing: Thaw frozen portions in the fridge overnight, or place in an oven-safe dish and wrap in foil, then bake for 10 minutes at 425°F or until fully warmed through.
• Reheating: French toast casserole can be reheated in the microwave if already cut into portions, or in the oven if you want to reheat the whole dish at once.
