Step by Step Instructions: How to Make Blueberry French Toast Casserole
Time needed: 10 minutes.
How to Assemble Blue Berry French Toast Casserole
- Prep the Bread
On a cutting board and using a sharp, serrated bread knife, cut the bread into bite-sized cubes. Spray an 8×8 inch casserole dish with cooking spray. Add the bread.
- Add the Blueberries
Add 1/2 cup of the blueberries to the top of the bread. Be sure to reserve ½ cup!
- Make the Egg Mixture
In a mixing bowl, whisk together the eggs, milk, melted butter, maple syrup, and vanilla.
- Add the Egg Mixture & Let it Rest
Pour the egg mixture evenly over the bread and blueberries and toss to make sure every piece of bread is moist. Sprinkle the remaining ½ cup of blueberries over the top. Cover and refrigerate for at least 3 hours and up to 24 hours, if not freezing.
- Bake It!
Preheat the oven to 350°F, while the casserole sits on the counter to warm slightly. Bake, uncovered, for 50-60 minutes or until golden brown on top and set in the middle. (If it’s browning too much on top, tent the casserole with foil.) Let the casserole cool for about 10 minutes.
- Make a Vanilla Glaze (Optional)
While the casserole cools, stir together the milk, vanilla, and salt in a small bowl. Add the powdered sugar and whisk until a thin, white glaze forms.
Use a spoon to drizzle the glaze over the casserole (you don’t have to use all of it). - Serve Warm!
How to Freeze a French Toast Casserole
One of the beauties of this recipe is it can be made ahead of time. It’s a perfect recipe to serve to groups of people since you can assemble it the night before and just pop it in the oven the morning you want to cook it.
Freeze For Later: Assemble the recipes as directed but don’t make it. Tightly wrap the dish in a few layers of plastic wrap or foil (or a tight-fitting lid), fill out and tape on the freezer label, and freeze.
Prepare From Frozen: Note: You will need to have the ingredients to make the Vanilla Glaze on hand. Thaw completely using one of these safe thawing methods. Bake as instructed!
How to Serve Blueberry Baked French Toast
Here are some serving suggestions for a baked french toast recipe.
Serve warm alongside other brunch or breakfast favorites like:
- Scrambled eggs (or hard-boiled eggs)
- Bacon (try our No Fail Bacon recipe)
- Fresh fruit
You can also mix this recipe up in a variety of ways. Here are some ideas:
- If you want to skip the Vanilla Glaze, just serve with real maple syrup on the side instead.
- Swap raspberries or chopped-up strawberries for the blueberries.
- Add some toasted sliced almonds to the top for a little crunch.

No need to slave away over the stove flipping French toast. Serve everyone at once with this easy and DELICIOUS Blueberry French Toast Casserole. What’s even better is this is a fabulous make-ahead breakfast casserole. Keep it in the fridge or pop it in the freezer for an easy breakfast on a busy morning.
Ingredients
For French Toast:
- 5 large eggs
- 1 cup milk (your choice)
- 1/4 cup melted salted butter, melted (DF option: Use ghee or melted coconut oil.)
- 1/4 cup pure maple syrup, plus more (optional) for serving
- 2 teaspoons pure vanilla extract
- Cooking spray
- 1 (10 ounce) loaf of sourdough bread* (GF option: Use gluten-free bread.)
- 1 1/2 cups fresh or frozen** blueberries
For Vanilla Glaze: (optional)
- 1 tablespoon milk (your choice)
- 1/2 teaspoon pure vanilla extract
- Pinch of salt
- 1/2 cup powdered sugar
*If you don’t have stale bread on hand, preheat the oven to 350°F. Place your bread cubes on a rimmed baking sheet and bake for 10 to 15 minutes, stirring at least once, until toasted. Let the bread cool before using.
**If using frozen blueberries, add them to the casserole while still frozen (do not thaw first). This helps prevent the berries from coloring the casserole too much.
Instructions
Make It Now:
- In a large bowl, whisk together the eggs, milk, melted butter, maple syrup, and vanilla.
- Spray an 8×8 inch casserole dish with cooking spray. Add the bread and 1 cup of the blueberries (reserve ½ cup). Pour the egg mixture evenly over the bread and blueberries and toss to make sure every piece of bread is moist. Spread the remaining ½ cup of blueberries on top. (Freezing instructions begin here.)
- Cover and refrigerate for at least 3 hours and up to 24 hours, if not freezing.
- Preheat the oven to 350°F, while the casserole sits on the counter to warm slightly. Bake, uncovered, for 50-60 minutes or until golden brown on top and set in the middle. (If it’s browning too much on top, tent the casserole with foil.)
- Make the Vanilla Glaze. In a small bowl, stir together the milk, vanilla, and salt. Add the powdered sugar and whisk until a thin, white glaze forms.
- Let the casserole cool for about 10 minutes. Then, use a spoon to drizzle the glaze over the casserole (you don’t have to use all of it). Serve warm, with more maple syrup, if desired.
Freeze For Later: Follow Steps 1-2, tightly wrap the casserole in plastic wrap or foil, and freeze.
Prepare From Frozen: Note: You will need to have the ingredients to make the Vanilla Glaze on hand. Thaw completely. Follow Steps 4-6.
Cooking Notes:
- If you want to double this recipe, make it in a 9×13 pan and bake for a bit longer, until set in the middle and golden brown on top.
If freezing, do I let it thaw before baking or bake it frozen? If baking frozen, how long do I bake it for?
Sorry! I see it saws thaw completely, totally missed it. Can’t wait to eat 😀
No worries. Let us know if you have any other questions!
How long can you freeze this for?
If you wrap it tightly with several layers of plastic wrap and/or foil, squeeze out as much air as possible, and stick it in the back of your freezer, I’d say it’s good for 3-6 months. But, as long as it’s stayed completely frozen, it’s safe to eat indefinitely according to the USDA!
So good! I made this for a birthday breakfast brunch for a work colleague and it was so yummy. I did add cinnamon because I love cinnamon, and it was great even without the glaze. There were no leftovers!!

Great idea to add cinnamon. Thanks for taking the time to leave a review, Linda!
