Why Casserole, and how is it different from a French Toast recipe

While a classic French toast is easy and sometimes a last-minute recipe for the whole family, you can make as few or as many slices as you wish. Baked french toast casserole is great for a crowd. It can be made ahead; you can customize it to fit your guests or add a personal touch.

This easy french toast bake takes only 10-15 minutes to assemble, it calls for simple ingredients, so it is the perfect recipe to construct the night before and bake the next morning just before serving time.

This is the perfect recipe for your weekend mornings, Christmas morning, easter morning, and even mother’s day brunch. Add it to your easy breakfast recipes repertoire, right next to these fluffy pancakes and apple muffins.


You will only need basic ingredients to make this perfect breakfast dish, and you can find the full list and measurements in the recipe card below. I listed substitution options next to each ingredient.

  • Brioche loaf. You can bake your own or get a loaf from your local grocery store. You can also use challah, and chocolate chip brioche bread.
  • Eggs, large.
  • Milk and heavy cream. You can also use whole milk, half and half, and plant-based milk.
  • Maple syrup. I like the delicious breakfast tones it adds to the casserole, but you can remove it or replace it with honey or brown sugar.
  • Ground cinnamon. You can add a pinch of nutmeg or ground cloves or remove it altogether.
  • Salt. Just a pinch to extract the flavors.
  • Vanilla extract. A small amount will make a huge difference; it rounds up the flavors and adds a light taste.
  • Optional add-ons options: for a special occasion or to match it to the season: chopped dried fruits like raisins, dates, apricots, chopped nuts, chocolate chips, cinnamon streusel, and fresh fruits like fresh blueberries, raspberries, or even bananas.

How to make Brioche french casserole

The first step is for when your bread is still fresh. The bread must be stale or dry to soak up the custard.

  1. Cut your bread into 1-inch cubes, and spread them over a baking sheet in a single layer. Bake for 20 minutes at 250F (121C). Toss it mid-bake.
  2. In a large mixing bowl, pour the milk, heavy cream, maple syrup, ground cinnamon, salt, vanilla extract, and eggs. Mix until smooth.
  3. Spread the bread in your baking dish, then pour the custard over the bread. Let sit for 15 minutes to soak in the liquids, and use a spoon or your fingers to toss the bread cubes once or twice gently.
  4. Sprinkle with slivered almonds or streusel if desired
  5. Bake according to the instruction below, remove from the oven and serve.

Note on baking the brioche cassarole

The casserole is ready when lightly golden on top, and the bottom is not completely dry and has yet to set. It will set as it cools down.

If you notice that the top of the casserole is browning too much, cover it with aluminum foil before it is ready.

Recipe tips and FAQ’s
