Can you prepare French toast casserole the night before?

Yes, you can assemble a Blueberry French Toast Casserole the night before. In fact, this allows the bread to soak up the custard mixture, resulting in a richer and more flavorful dish. Just cover it tightly and refrigerate until ready to bake.

How do you keep French toast casserole from being soggy?

To prevent a soggy Blueberry French Toast Casserole, use slightly stale bread. This will absorb the custard without becoming overly saturated. Also, don't over-soak the bread; a few hours or overnight is sufficient. Ensure your oven is preheated to the correct temperature for even baking.

What goes well with French toast casserole?

Blueberry French Toast Casserole pairs wonderfully with a variety of sides. Consider serving it with fresh fruit, such as berries or sliced bananas. A dollop of whipped cream or a drizzle of maple syrup also complements the dish perfectly. For a more savory option, serve alongside crispy bacon or sausage.

How long does French toast casserole last in the fridge?

Blueberry French Toast Casserole can be stored in the refrigerator for up to 3-4 days. Make sure to cover it tightly to prevent it from drying out.

Can I freeze a French toast casserole?

Yes, you can freeze Blueberry French Toast Casserole either before or after baking. If freezing before baking, assemble the casserole, wrap it tightly in plastic wrap and then foil, and freeze for up to 2-3 months. Thaw overnight in the refrigerator before baking. If freezing after baking, let the casserole cool completely, then wrap and freeze as described above. Reheat in the oven until warmed through.

What kind of bread is best for French toast casserole?

Challah, brioche, or French bread are excellent choices for Blueberry French Toast Casserole. These breads have a rich, slightly sweet flavor and a texture that holds up well to soaking in the custard. Day-old bread is ideal as it absorbs the custard better without becoming mushy.

Instructions

Grease a 9×13 inch baking dish. Spread bread cubes evenly in dish and scatter blueberries over top.
In a large bowl, whisk eggs until frothy. Add milk, cream, granulated sugar, vanilla, 2 tsp cinnamon, nutmeg, and 1/4 tsp salt. Whisk until combined.
Pour custard mixture evenly over bread and blueberries. Press down on any dry cubes to submerge.
For the streusel, combine flour, brown sugar, 1 tsp cinnamon, and 1/4 tsp salt in a bowl. Cut in cold butter until mixture resembles coarse crumbs.
Sprinkle streusel evenly over casserole. Cover and refrigerate for at least 2 hours, or overnight.
Preheat oven to 350°F (175°C). Let casserole sit at room temperature while oven heats.
Bake uncovered for 45-55 minutes, until top is golden brown and center is set.
Let cool for 10 minutes before serving.

Notes

Using stale bread is crucial for the best texture. Do not skip the chilling step, as it allows the bread to fully absorb the custard. Leftovers reheat beautifully in the oven to restore the crispy topping.
