Growing up, French toast was one of my absolute favorite breakfasts. My dad used to make the BEST French toast.
His secret? Extra vanilla.
I always liked my French toast with a little crispy edge and lots of maple syrup on top. I’ll take French toast over pancakes any day, though I’m realizing most people don’t agree!
So whenever there’s a special breakfast or brunch, I always make something French toast inspired.
This Lemon Blueberry French Toast Casserole is so simple and easy to make and can be done the night before you plan on serving it. It’s absolutely perfect for Easter, Mother’s Day, or even Christmas morning! And I find it holds up well after baking for at least a few hours too.
The texture is really a cross between French toast and bread pudding. The exterior has a slight crunch, but the inside is ultra rich, soft, and almost like custard.
Your whole family is going to love this baked French toast casserole!

Lemon Blueberry Topping
The blueberry topping on top is definitely worth the extra effort. Not only does it taste incredible, but it adds such a pretty, springy look and flavor to this breakfast casserole. It can be made, cooled, covered, and refrigerated for a few days. Just rewarm when ready to serve!
What to Serve with French Toast Casserole?
- Fresh berries – raspberries, strawberries, additional blueberries are all great choices

What is the Best Pan for French Toast Casserole?
This Lemon Blueberry French Toast Casserole was written for a 9 x 13-inch baking dish. I always prefer to bake in a good-quality light-colored metal pan, like this one, but a glass or ceramic pan will work, too. Learn more about why I prefer metal baking pans here.

Cover well with plastic wrap or foil and store in the fridge for a couple of days. I haven’t tried freezing this recipe personally, but due to its eggy nature, I don’t think it would freeze well, so I wouldn’t recommend it.

Hands down the best recipe I’ve ever pulled from Pinterest! This will go into my special occasion rotation.
Thank you!
Yay!! So happy you loved this recipe, thanks so much for letting us know! 🙂
Hi. Can you freeze this dish? We are going away and having brunch on the last day. I want something I can have prepared and just throw in the oven on our last morning. Thanks!
Unfortunately, I think it’s too egg heavy to freeze well. Sorry!
Love this dish! I’ve made it for Mother’s Day, Easter brunch and my daughter’s baby shower brunch. Delicious and easy!
So wonderful! I’m happy to hear you’ve used this recipe to celebrate with 🙂
I am with you – french toast is so much better than pancakes (my opinion). This is such a great recipe and I appreciate the video to make my own challah. What a wonderful plus! Thank you for all your great recipes and your wonderful instruction videos.
I, too, was wondering why the egg/milk mixture is added in two steps – should I stir before adding the second half? Like another commenter, was also wondering if I need to cover the dish when baking. Thanks!
Terrific recipe, worth making – we had it for brinner!
For anyone questioning covering the dish or not, the recipe clearly states that the dish is covered before refrigeration and baked uncovered. Really not trying to be snarky, but bloggers can’t answer every question about things that are already clearly stated in the recipe:
“Top with the remaining egg-milk mixture to cover completely. Cover the pan and refrigerate for at least 2 hours or overnight.
Preheat the oven to 350°F.
Bake uncovered for 40 minutes, or until golden brown.”
Hi Tessa!
Your Lemmon Blueberry French Toast sound heavenly and would be a perfect accompaniment for my Easter brunch. I’m a little confused though as to if I should keep it covered when it goes in the oven or do I uncover to bake it?
I am totally missing something…..
Place the bread cubes in the prepared pan. In a…… Pour half of the egg-milk mixture over the bread.
Top with the remaining egg-milk mixture to cover completely. Cover and refrigerate for at least 2 hours or overnight.
What do I do between the two halves of egg milk mixture?
Not bad, had good flavour and it strue that its a cross between bread pudding and french toast. I would omit the syrup as it was really sweet with good flavor.
Ohmigosh! This turned out so well! Divine. I doubled the recipe and made this in a 10 x 15 casserole dish. I also made double the sauce which really wasn’t necessary. Both were just so delicious and a huge hit at my Mother’s Day brunch. I used fresh blueberries for the casserole and frozen blueberries for the sauce. Huge organic blueberries in both cases. Worked great. Thank you!
Wonderful!! So happy to hear that. Thanks for sharing 🙂
Can I use frozen blueberries for the sauce?
This was delicious!!!!! Tessa you are quite something! I’m ready to eat it again!! I strongly recommend this dish to all!!!
I’m still on a diet but screw that! How can I not make this?!? I’m totally with you when it comes to French toast over pancakes, let the haters hate! I need to go buy the blueberries asap
Haha! 🙂
Hi Tessa,
Love your new design! And also love this recipe. Anything with bread is good, will keep this for a weekend.
