If you are looking for a comforting breakfast that feels special enough for a weekend brunch but is simple enough to prepare ahead of time, this Blueberry Almond French Toast Casserole is a wonderful choice. It combines soft, custardy bread with juicy blueberries, crunchy almonds, warm cinnamon, and a lightly golden top. The result is a delicious baked breakfast that is creamy in the center, slightly crisp around the edges, and packed with sweet berry flavor. It is especially good served warm with maple syrup, powdered sugar, fresh berries, or a spoonful of whipped cream.
This French toast casserole is also an excellent make-ahead recipe. Instead of standing over a skillet cooking individual slices of French toast, you simply assemble everything in one baking dish and let the oven do the work. This makes it ideal for holidays, family breakfasts, Mother’s Day, Christmas morning, brunch gatherings, or lazy Sunday mornings. The bread absorbs the sweet egg mixture overnight, allowing every piece to become soft, flavorful, and custardy while the top develops a beautiful golden-brown finish.
The combination of blueberries and almonds gives this casserole a fresh and slightly nutty flavor that makes it different from traditional French toast. You can use fresh or frozen blueberries, depending on what you have available, and sliced almonds provide a pleasant crunch on top.

6 large eggs
2 cups whole milk
1 cup heavy cream
½ cup granulated sugar
2 teaspoons vanilla extract

Kitchen Equipment
9-by-13-inch baking dish
Large mixing bowl
Whisk
Measuring cups and spoons
Rubber spatula
Small saucepan or microwave-safe bowl
Sharp knife
Preparing the Bread
Begin by cutting the bread into approximately one-inch cubes. Slightly stale bread works especially well because it absorbs the custard without becoming overly soggy. If your bread is very fresh, spread the cubes on a baking sheet and allow them to sit uncovered for several hours, or lightly toast them in the oven for a few minutes.
Brioche and challah are excellent choices because their rich, slightly sweet flavor creates a luxurious French toast casserole. A crusty French bread also works beautifully and provides a slightly firmer texture.
Lightly grease a 9-by-13-inch baking dish with butter or nonstick cooking spray. Spread the bread cubes evenly across the bottom of the dish.
Adding the Blueberries
Scatter approximately one and a half cups of blueberries over the bread cubes. Reserve the remaining blueberries for the top.
Try to distribute the berries evenly so every serving gets plenty of fruit. If you’re using frozen blueberries, there is no need to thaw them first. Add them directly to the casserole.
Preparing the Custard
In a large mixing bowl, whisk together the eggs, whole milk, heavy cream, granulated sugar, vanilla extract, cinnamon, nutmeg, and salt.
Whisk until the eggs are completely incorporated and the mixture looks smooth.
Pour the custard evenly over the bread and blueberries. Press the bread gently down with a spatula or the back of a spoon so the pieces can absorb the custard.
Allow the casserole to rest for at least 20 to 30 minutes before baking. For the best flavor and texture, cover the dish and refrigerate it overnight. This allows the bread to absorb the custard completely.
Preparing the Almond Topping
When you’re ready to bake, remove the casserole from the refrigerator and let it sit at room temperature for approximately 20 to 30 minutes.
Melt the butter and drizzle it over the top of the casserole. Sprinkle the brown sugar and sliced almonds evenly across the surface.
Add the remaining blueberries over the top. The almonds will become lightly toasted during baking, while the brown sugar creates a delicate caramelized finish.
Baking the Casserole
Preheat your oven to 350°F (175°C).
Cover the casserole loosely with aluminum foil and bake for approximately 30 minutes. Remove the foil and continue baking for another 20 to 25 minutes.
The casserole is ready when the center is set, the bread is puffed, and the top is golden brown. A slight softness in the center is fine, but it should not look liquid or completely wet.
Allow the casserole to cool for about 10 minutes before serving. This short resting period allows the custard to finish setting and makes the casserole easier to cut.
Serving Suggestions
Serve the Blueberry Almond French Toast Casserole warm with a generous drizzle of maple syrup. The sweetness of the syrup pairs beautifully with the slightly tart blueberries and rich custard.
For a pretty presentation, sprinkle powdered sugar over the top just before serving. Add a few fresh blueberries and extra sliced almonds for color and texture.
A spoonful of whipped cream or Greek yogurt also makes a delicious topping. If you enjoy citrus flavors, add a little freshly grated lemon zest before serving. Lemon brightens the blueberry flavor and adds a fresh finish.
For an extra-special brunch, serve this casserole alongside crispy bacon, breakfast sausage, fresh fruit, or a simple green salad.
Helpful Tips
Choose bread that is slightly dry or stale for the best texture. Fresh, soft bread can absorb too much custard and become overly mushy.
Do not skip the resting time. Allowing the bread to absorb the egg mixture is what gives the casserole its creamy interior.
If you prefer a less sweet breakfast, reduce the granulated sugar slightly and allow maple syrup to provide sweetness when serving.
Keep an eye on the casserole during the final minutes of baking. If the top begins browning too quickly, loosely cover it with foil.
Allow the casserole to rest after baking before cutting. This helps the layers hold together better.
Easy Recipe Variations
You can easily change this recipe depending on the ingredients available in your kitchen. Try replacing the blueberries with strawberries, raspberries, blackberries, or a combination of berries.
For a blueberry-lemon version, add one tablespoon of fresh lemon zest to the custard. The bright citrus flavor works beautifully with blueberries.
For a cinnamon-pecan version, replace the almonds with chopped pecans and increase the cinnamon slightly.
You can also add a thin layer of cream cheese between the bread and berries. Simply soften cream cheese, mix it with a little powdered sugar and vanilla, then dollop it throughout the casserole before adding the remaining bread and blueberries.
For a richer dessert-style casserole, sprinkle a few white chocolate chips over the bread before adding the custard.
Make-Ahead Instructions
One of the best things about this recipe is that it can be prepared the night before. Assemble the entire casserole, cover it tightly, and refrigerate overnight.
In the morning, remove the casserole from the refrigerator while the oven preheats. Add the almond and brown sugar topping just before baking.
This makes breakfast extremely easy when you’re hosting guests. You can prepare everything ahead of time and simply bake it in the morning.
Storage Instructions
Store leftover French toast casserole in an airtight container or cover the baking dish tightly with plastic wrap or foil. Refrigerate for up to three days.
To reheat, place individual portions in the microwave for approximately 30 to 60 seconds, or warm the casserole in a 325°F oven until heated through.
You can also freeze portions for longer storage. Allow the casserole to cool completely, wrap individual portions securely, and freeze. Thaw overnight in the refrigerator before reheating.
