Overnight Blueberry French Toast Bake

It’s here! Now anyone can make French Toast! This Overnight Blueberry French Toast Bake is perfect for a special occasion like Mother’s Day and easy enough for a weekend treat. Just layer buttery croissants, blueberries and a maple-flavored egg mixture into a baking dish, chill one hour or overnight, then bake. Serve it sprinkled with confectioner’s sugar and extra blueberries for a seasonally sweet breakfast treat. Dairy-free option available.

Serving on spring flowered plate with syrup and casserole.

French Toast is one of my favorite breakfast items to order when I go out to eat. And it seems like the only time I make it at home is for a special occasion. I mean, I love my Strawberry Stuffed French Toast and Apple French Toast Muffins but this Overnight Blueberry French Toast Bake is so much easier that I actually make it more often whenever that French Toast craving hits.

My husband is the one who actually found this recipe first and made it for me last Mother’s Day. Don’t you love it when your hubby takes the time to look up a recipe that he thinks you’ll  like and takes the time to get the ingredients to make it? I certainly do!

Pouring syrup on french toast .

And let me tell you, this one was one delicious breakfast bake and, since I watched him make it, it’s as easy as 1-2-3. We did make a few changes from the original recipe that he found on BuzzFeed by using fewer eggs and adding vanilla extract, cinnamon and, of course, some Grand Marnier.  You can also make it dairy-free, which he did for me, and you won’t be able to tell the difference.

Bite of breakfast casserole.

Of course, the best part is eating it. Now pour on the syrup and dig in! Doesn’t that bite just make you want to jump up and go whip it up now? Check out just how easy it is below.


  • Change out the blueberries for strawberries, apples, peaches or cherries.
  • Want a more crunchy casserole? Add chopped pecans or your favorite nut.
  • Want something a little more hearty? Add chopped cooked bacon, ham or crumbled sausage to the mix.
  • Love even more sweetness? Add a crumb layer on top just prior to baking. (see crumb topping from my Lemon Blueberry Muffins

Best bread for French Toast

There are so many delicious breads that can be used beside the croissants used here. Just look for a denser bread that will hold up to the egg batter. Breads such as:

  • Brioche bread – (one of my favorites) is a rich, sweetened bread made with a ton of butter and eggs.
  • Challah is a rich, dense egg bread, no butter, that is sweetened with a bit of honey.
  • For a more savory French toast, both sourdough and French bread can be used.

Can you freeze this casserole?

Most definitely! I do it all the time since there is just the two of us now. I like to let it cool, cut it in square and wrap well in plastic wrap. Freeze. At this point, the pieces can be combined in a large resealable plastic bag to protect them from freezer burn. When you are ready to eat them, thaw in the refrigerator (or I’ve even thawed them in microwave) then pop them into the microwave for 1-2 minutes to reheat. If you are reheating a number of servings, thaw and place in casserole dish and reheat for 20 minutes in a 350 degree oven.


Coating blueberries with flour step.

  1. Add flour and powdered sugar to blueberries.
  2. Toss together. This will help prevent the blueberries from sinking to the bottom.

Layering croissants and blueberries into casserole dish.

  1. Cut croissants into pieces and spread in bottom of greased casserole dish. This nonstick spray step will help prevent the bread from sticking and will make clean up a breeze.
  2. Sprinkled floured blueberries on top of croissants.

Making batter and pouring over casserole.

  1. Stir together eggs, yogurt, vanilla and cinnamon.
  2. Add in maple syrup and Grand Marnier and mix well.
  3. Pour batter on top of croissants and blueberries. Cover the casserole dish tightly with plastic wrap and refrigerate overnight. 

After overnight soaking the casserole is ready to bake.

  1. Just look at how all that egg-yogurt batter has been soaked up by the bread! When you’re ready to bake it, preheat the oven to 350 degrees, remove plastic wrap and bake. When it starts to cook, you’ll love the aromas of blueberries and cinnamon coming out of your kitchen.  

Beautiful baked french toast casserole.

My mouth is watering just waiting for this easy overnight blueberry French toast to be done. You’ll be super impressed with the beautiful golden brown of the croissants and the plumpness of the blueberries just waiting to burst forth with their flavor when you take a bite. Now, sprinkle with some powdered sugar for a little extra sweetness and a finished gourmet look.

I like to serve mine with extra blueberries, a light sprinkle of confectioner’s sugar and a side of maple syrup. Yum! Now comes the easy part, grab a fork and dig in. Believe me, it has all the flavors you love about French Toast, the slightly toasted exterior and a sweet and moist blueberry and maple-flavored inside. In fact, it’s so good you won’t want to put your fork down! And it’s not only great for special occasion breakfasts or brunches like Mother’s Day but feeds a crowd super easy too. Enjoy!
