Why You’ll Love This Berry French Toast Casserole
Nothing gives me more joy than waking up on a holiday morning with all my children home! While several are grown and have homes of their own, I always make an easy breakfast casserole recipe to serve when we’re all together.
I love that this Berry French Toast Casserole has berries and nuts, which gives it delicious sweetness and crunch! But also, this casserole can be made ahead of time, which is quite a lifesaver during these visits.
Here’s why it’s a favorite:
- I used my tried-and-true French Toast Casserole recipe as a base, which means you already know it’s going to be a winner!
- The nuts add crunchy texture and flavor, making this breakfast casserole irresistible! (If you love nuts for breakfast, be sure to try my Healthy Banana Nut Pancake and Caramel Bread Pudding too.)
- This berry French toast casserole is quick and easy to assemble, which is always a plus in the lead up to a holiday!
- It effortlessly goes from breakfast to dessert! (I mean, French toast casserole is basically bread pudding, right?!) Serve it warm with a scoop of our berry ice cream or berry crumble.
Important Ingredient Notes
- Unsalted butter – Using unsalted butter keeps your French toast casserole from being overly salted.
- Light brown sugar – This has a milder flavor than dark brown sugar so it won’t over-power the berries.
- Brioche bread – Brioche is my favorite for French toast since it’s tender, rich, and a little bit sweet. You could swap it out for texas toast or cinnamon raisin bread too.
- Eggs – The liquid mixture for French toast is custard, so eggs are a key component!
- Milk – Whole milk will give you the richest berry French toast casserole, but whatever you have on hand is just fine.
- Flavorings – Cinnamon adds cozy flavor, then you’ll also use vanilla and maple extracts. You can swap the maple extract for almond extract if you’d prefer.
- Frozen triple berry blend – Or any frozen berries you like.
- Walnut pieces – For crunch and nutty flavor!
- Maple syrup – Or another topping you like. Whipped cream would also be delicious!
How to Make Berry French Toast Casserole
Prepare: Preheat your oven to 350ºF and spray a 13×9 baking dish with non-stick baking spray.
Make the Topping: In a small bowl, mix together the walnut pieces with the softened butter and brown sugar.
Make the Brown Sugar Layer: In a small saucepan, melt the butter with brown sugar, whisking until the sugar dissolves. Pour this into the bottom of the greased baking dish.
Add the Bread: Arrange the bread cubes over the butter mixture.
Make the Custard: In a large bowl, whisk the eggs, milk, cinnamon, vanilla, maple extract, and salt. Pour the custard over the bread.
Bake: Add the berries and walnut mixture over the bread, then cover with foil and bake for 30 minutes. Remove the foil and bake an additional 20 minutes, then serve warm with maple syrup.
Tips and Tricks
- Use a good quality sweet bread as your base. I love to use a soft brioche bread, but Hawaiian bread or cinnamon raisin bread would also be delicious.
- I topped the casserole with frozen mixed berries. No need to thaw them. You can also use 2 cups of fresh berries.
- It’s easiest to use your hands when combining the sugared walnut mixture. You want to make sure there are no loose crumbs as it all comes together to coat the walnuts completely.
- Sprinkle with powdered sugar instead of maple syrup—or in addition to it! The sugar makes a beautiful presentation as well.
Recipe FAQs
If your French toast casserole is soggy, you’ll need to bake it longer. The custard should be set when you pull the casserole out of the oven.
If you’d like the bread to be a little bit firmer after baking, you can start with stale bread or toast the bread first. This isn’t necessary, though—it simply depends on your desired results!
I don’t recommend letting the assembled casserole sit in the refrigerator longer than overnight. I usually put it together the night before and then bake it in the morning.
