This Berry French Toast Casserole is the perfect make-ahead breakfast or brunch. The best part is it’s easy to customize with your favorite mixed berries! Overnight french toast casseroles are a great option for just about any event especially if you need to come up with something fast that will feed a ton of people and won’t take much to prepare. Anyone can really make this casserole. It can easily be halved for smaller gatherings.
Breakfast foods of any kind, will always be my favorite. Oatmeal, pancakes, waffles, bacon, muffins, eggs.. all of that! This Berry French Toast Casserole is a perfect way to use up some of the berries that you have sitting in the fridge. I love using fresh berries for this casserole however, frozen works perfectly fine too. No need to thaw the frozen berries first; just layer them in the casserole as you would with the fresh berries.
Quick Tips:
- Slice the strawberries ahead of time.
- Cut the bread in advance.
- Mix the egg and milk mixture the night before.
- Assemble everything the night before and store it in the fridge overnight to soak up all that goodness.
In my most humble opinion, the best way to serve this amazingness is to drizzle some maple syrup (especially the fancy kind!) on top. And of course, pair it with a few slices of bacon!

Rhonda J Walsh says
you say a 9×13 dish, but yet your picture is in a pie plate? Can it be made in a 9″ deep pie dish?
Chef Elizabeth Reese says
Hi Rhonda! You can most certainly use a casserole dish or a round pie dish, whatever you have on hand will work perfectly fine!
Vanessa D says
Do you bake covered with foil or uncovered?
Chef Elizabeth Reese says
Hi Vanessa! You can bake the casserole uncovered.
Judy says
Made this day before Christmas Eve and cooked Christmas Eve morning while family drove over here. Came out wonderfully delicious and got compliments from everyone!
Chef Elizabeth Reese says
Hi Judy, Im glad your family loved it!
Betsy Wunder says
Sounds delicious. Can frozen fruit be used?
Chef Elizabeth Reese says
Hi Betsy- I wouldn’t recommend using frozen fruit because the excess water could create additional moisture and make the bread soggy. If you can use fresh fruit I strongly recommend it!
