Blueberry Baked French Toast Casserole

Wake up to the smell of fragrant blueberries baked into this lusciously decadent overnight casserole recipe. No need to get up early to put it together, because all the work is done the night before! Just assemble, cover, and refrigerate overnight.

The bread soaks up the custard mixture so that it is ready to go in the morning! While this breakfast is delicious and filling, we often add in a side of grapefruit sections or a Fresh Summer Fruit Salad!

How to Make Baked French Toast

This easy French toast starts with bread of course! Regular white bread works (or really, any leftover bread or even leftover dinner rolls) but we get the best results from a denser bread such as brioche or Challah as it holds the custard perfectly.

You want the bread to be slightly dry, so cut it and leave it to sit out overnight. It can also be dried in an oven at 350˚F for about 8 minutes.

To Make French Toast Casserole

  1. Combine the cream cheese, sugar and lemon juice and mix until fluffy.
  2. Layer the bread cubes in a casserole dish, add cream cheese and blueberries.
  3. Combine eggs & milk to create a custard and pour over the bread cubes. Refrigerate overnight.
  4. Top with the streusel topping and bake until golden!

How Long to Bake French Toast Casserole? Leave this french toast bake at room temperature for about 45 minutes while the oven preheats. Like most make ahead casserole recipes, the center of this french toast bake is really cold so leaving it at room temperature for a little bit helps it to bake evenly.  Add topping and bake uncovered for 45-55 minutes.

  1. This turned out perfect the first time with no changes and baking time was actually right on, mine was pretty thick (We used challah bread which would be hard to not do everytime it has such a great texture) so I wasn’t sure it would be enough time. It was the perfect sweetness on its own and not over the top – the cream cheese mixture absolutely made it for me. Everyone loved it and talked about what it would cost for one slice at a breakfast restaurant. I was wondering if you think you could successfully freeze this in individual portions to heat up in the microwave?5 stars

    1. I haven’t tried freezing this but I think it would work just fine, it’s basically french toast which we do freeze often!

  2. Hi … can you do 2 days overnight, instead of one? Making for Christmas and Christmas Eve will be pretty crazy.

  3. Incredibly good! Best breakfast/dessert ever! Love it with warm maple syrup poured on top!
    It was a gigantic hit with EVERYBODY!5 stars

  4. Made a half recipe in an 8×8. This was spectacular!! We used gluten free sandwich bread, but otherwise made as directed. It was done in 40 minutes and came out golden brown perfection. We’re going to do a strawberry/raspberry combo next time. Thank you for another wonderful recipe, Holly!!5 stars

  5. I made this recipe this morning, and I have to say that it has taken over an hour and a half to bake so far! It passed the clean knife test after an hour, but the bread was still soggy. I’ve baked it another 30 minutes and it’s still kind of soggy. I think if I were to make it again, I’d use less eggs and even possibly cut out the cream cheese mixture.2 stars

    1. As this is French toast, the texture is expected to be quite soft and moist (almost like a bread pudding). Hope that helps.

  6. This looks amazing! I might try this with brie instead since my husband and daughter aren’t big cream cheese fans. Can I just mix the sugar in with the eggs? Thanks :)

    1. Definitely. Step 4 of the recipe stated to pour the egg mmixture over the bread cubes, cover with foil and refrigerate overnight.

  7. Hi Holly, Love your recipes, you need a TV show! Just wanted to know about the bake time in cutting this in half, only 2 of us. 8 X 8 dish still 45-55? Thanks

    1. Hi Donna, thanks so much for your kind words!
      Generally, if you make half the recipe your cook time decreases by about a ⅓. I hope this helps!

    1. I haven’t tried it with Splenda so I can’t say for sure but there should be directions on the Splenda package to substitute for sugar.

    1. I haven’t tried it but I think it would work. Strawberries tend to contain a bit more moisture than blueberries so if you are using frozen, you might like to defrost/drain them first. If you try it that way, I’d love to hear how it works for you.
