How to Make French Toast Casserole
Step 1
Lightly grease a 9x13-inch baking dish and evenly spread the cubed brioche bread across the bottom.
Step 2
In a large bowl, whisk together the eggs, whole milk, heavy cream, brown sugar, vanilla extract, cinnamon, and nutmeg until smooth.
Pour the custard evenly over the bread, gently pressing the bread into the liquid so every piece absorbs the mixture.
Cover tightly and refrigerate overnight, or for at least 8 hours.
Step 3
The next morning, remove the casserole from the refrigerator while the oven preheats to 350°F.
Step 4
Prepare the streusel topping by combining the flour, brown sugar, and cinnamon. Cut in the cold butter using a pastry cutter or fork until the mixture resembles coarse crumbs.
Sprinkle the streusel evenly over the casserole.
Step 5
Bake for 45 to 50 minutes, or until the top is golden brown and the center is fully set.
Step 6
Allow the casserole to rest for about 10 minutes before serving.
Dust with powdered sugar and drizzle with warm maple syrup. Top with fresh strawberries or your favorite berries.

What Bread Is Best for French Toast Casserole?

Expert Tips
Day-old brioche produces the best texture because it absorbs more custard without becoming mushy. Allowing the casserole to rest overnight gives the bread plenty of time to soak up the rich egg mixture, resulting in a creamier center. Freshly grated nutmeg provides deeper flavor than pre-ground, and letting the casserole rest after baking makes slicing much easier.
Frequently Asked Questions
Can French Toast Casserole be made ahead of time?
Yes. In fact, overnight French Toast Casserole tastes even better because the bread has time to fully absorb the cinnamon vanilla custard before baking.
Can I freeze French Toast Casserole?
Yes. Bake the casserole completely, allow it to cool, then wrap tightly and freeze for up to three months. Thaw overnight before reheating.
Can I use regular sandwich bread?
You can, but brioche, challah, French bread, or Texas toast produce a much richer texture and hold up better after soaking.
How long does French Toast Casserole last?
Store leftovers in an airtight container in the refrigerator for up to four days. Reheat individual servings in the microwave or warm larger portions in the oven.
