Easy French Toast Casserole
French toast casserole is one of my go-to brunch recipes, especially around the holidays when I’m feeding a crowd. Instead of standing over the stove flipping slice after slice, I can just toss the bread cubes into a dish, pour over the custard, and let the oven do the work. It comes out golden on top, soft in the middle, and the pecan crunch gives it some texture.
What I love most is how low-effort it is. I don’t even have to prep it the night before. If friends or family pop over at the last minute, I can pull this together in about 10 minutes and still look like I planned ahead. Between the cinnamon custard and the crusty French bread, this French toast casserole always disappears fast.
Happy Cooking!

French Toast Casserole Ingredients
- Bread: I like to use a day-old loaf of French bread for this French toast casserole recipe, but you can also use a baguette, brioche, sourdough, or challah.
- Eggs: Room temperature eggs are best!
- Milk: Go for whole milk if you can.
- Greek Yogurt: I like to use plain, full-fat Greek yogurt for this recipe, but low-fat will work, too.
- Chopped Nuts: Pecans are my favorite, but any chopped nuts will do.
- Seasoning: I like to use maple syrup as a sweetener in this recipe, along with vanilla, cinnamon, and salt for flavor.

Ingredients
- 1 loaf French bread cut into 1-inch cubes
- 8 eggs beaten
- 2 cups milk
- 1 cup Greek yogurt
- ¼ cup maple syrup plus more for drizzling
- 1 ½ teaspoons cinnamon
- 1 teaspoon vanilla extract
- ½ teaspoon salt
- ½ cup chopped pecans
Instructions
- Preheat the oven to 350°F and grease a 13×9-inch baking dish
- Place the bread cubes in the greased baking dish; set aside.
- In a large bowl, combine eggs, milk, Greek yogurt, maple syrup, cinnamon, vanilla and salt. Pour evenly over the bread cubes. Use a spoon to carefully coat all the bread cubes with the batter.
- Top the french toast with the chopped pecans. Then drizzle more maple syrup over the pecans.
- Bake in the preheated oven for 40-50 minutes, or until a knife inserted in the center comes out clean. If the top starts browning too quickly, loosely cover with foil for the last 10 minutes to prevent the casserole from drying out.
- Let stand for 5 minutes to cool. Serve with maple syrup if desired.

FAQs
Store any leftovers in an airtight container for up to 4 days in the fridge. You can reheat individual slices in the microwave, but the best way to reheat is to pop the baking dish back in the oven at 350°F for about 10 minutes to warm the French toast through and re-crisp the top.
Yes, you can freeze this healthy breakfast casserole in an airtight container, freezer bag, or wrapped in the baking dish for up to 3 months. Thaw it in the refrigerator before reheating according to the instructions above.
You can make the batter up to 24 hours ahead of time! You can also prepare the entire dish in advance if you have very thick and crusty bread that will hold up to being soaked for hours. If you do, keep it covered in the fridge.
If your French toast casserole turned out soggy, it’s likely because your bread soaked for too long in the custard, or because the bread was too soft to begin with. If you use tender bread like challah or brioche, it should be either stale or toasted.

Is this recipe “diabetic friendly”? Would it spike your sugar level?
I’m so sorry Ken, I’m not sure. I recommend checking with a nutritionist or registered dietitian.
Good morning Yumna, no problem – Thank you for the reply, I’ll probably give the recipe a try just edit some ingredients. Have a great day
You’re welcome, Ken. I hope you enjoy!
Can this be made in a slow cooker and if so how do you time?
So sorry, I’ve never tried making this French toast casserole in a slow cooker so I’m not sure how long it would take! I think it would work but you’ll have to experiment with the timing.
I am so excited to try this.
Would this be something I could make ahead and freeze?
Yes, absolutely! You can make this French toast casserole and store in your freezer in an airtight container, freezer bag, or wrapped in the baking dish for up to 3 months.
Have you tried using dairy free yogurt? Was it plain or flavoured? What about using a vanilla flavoured yogurt? Thanks!
Hi Nichole, I haven’t tried dairy-free yogurt in this recipe before but I think plain or vanilla would work great!
Super yummy!!! ๐
So glad you liked it, Jamie!
Does this taste sour at all because of the Greek yoghurt? My kids donโt like the taste of yoghurt and Iโm curious if you can taste it in this recipe.
No, I do not think they will detect the taste of yogurt. It just adds creaminess and most of the flavor comes from maple syrup, cinnamon and vanilla.
Easy and delicious! Will make again!
Thank you so much!
