How to Make Traditional French Toast Casserole

Ready to whip up your own Traditional French Toast Casserole? Let’s walk through the process step-by-step. First, gather your ingredients, and then let’s dive in!

Ingredients

  • 1 loaf brioche (challah or French bread, cut into 1-inch cubes)
  • 6 large eggs
  • 2 cups whole milk
  • 1/2 cup granulated sugar
  • 1 tablespoon vanilla extract
  • 1 teaspoon ground cinnamon
  • 1/4 teaspoon salt
  • 1/2 cup unsalted butter (melted)

Now let’s chat about what these key ingredients do in our dish.

  • Brioche: This rich, buttery bread is what makes this casserole extra special. Its tender crumb soaks up the custard beautifully, creating that sought-after texture.

  • Eggs & Milk: These are the backbone of our custard mixture. They provide creaminess and richness, ensuring each bite is smooth and decadent.

  • Sugar & Cinnamon: These classic flavor pairings add warmth and a touch of sweetness. The cinnamon brings a comfortingly familiar aroma that makes this dish feel like a warm hug.

  • Vanilla Extract: A splash of vanilla elevates the dish, giving it an irresistible aromatic quality that lingers beautifully in the air.

  • Butter: Drizzling melted butter on top not only enhances flavor but also creates a delightful crispiness that contrasts perfectly with the soft, soaked bread.

Feel free to play with substitutes: if your pantry is running low on brioche, challah works wonderfully too! You can even opt for a gluten-free bread, if needed.

Directions

To start, preheat your oven to 350°F (175°C). While that warms up, generously grease a 9×13-inch baking dish with butter or nonstick spray. This prevents any sticking woes and helps achieve that golden brown top.

Next, spread your bread cubes evenly in the prepared baking dish. The more uniform, the better—this will ensure each piece gets soaked evenly in that rich custard.

In a large mixing bowl, whisk together the eggs, milk, sugar, vanilla extract, ground cinnamon, and salt until well combined. This is the magic mixture that transforms simple bread into a custardy delight. You’ll want to whisk until no streaks remain and it looks smooth—this is when it starts to smell amazing!

Once mixed, pour this egg mixture evenly over the bread cubes, gently pressing them down with your fingers so they can soak up all that luscious custard. Don’t worry if it looks a bit thick at this stage; it will smooth out as it bakes.

Now, for a touch of decadence, drizzle the melted butter evenly over the top. You’ll notice how it pools in the nooks and crannies of the bread.

Let your casserole sit for about 10 minutes—this gives the bread time to soak up the custard. Meanwhile, if you want, you can take a taste of the egg mixture to check for sweetness; get creative and adjust it to your liking.

Now it’s time to bake! Place the dish in your preheated oven and let it bake uncovered for about 40 minutes. You’ll want to keep an eye on it; you’ll notice the edges turn golden and crispy while the center gets set. When it looks perfect, remove it from the oven and let it cool slightly before serving.

Serve it warm with maple syrup for drizzling, a dusting of powdered sugar, or simply pile on fresh berries. The choices are endless!

How to Serve Traditional French Toast Casserole

This dish shines as a mouthwatering centerpiece for breakfast or brunch gatherings. Picture serving it at a cozy family brunch or as the star of your holiday morning spread. Its golden crust and custard-like interior look beautiful on any table.

You can slice it into squares and serve it in the dish itself, adding a sprinkle of powdered sugar for that café-style finish. For a more elegant touch, garnish each plate with fresh fruit or a dollop of whipped cream.

Pair it with a steaming cup of coffee, or perhaps mimosas for a festive flair. Whether it’s a sunny Sunday morning or a holiday breakfast, this casserole is sure to charm everyone around the table.

How to Store Traditional French Toast Casserole

If you happen to have any leftovers—though it’s usually devoured quickly—you can store them in an airtight container in the refrigerator for up to three days. When you’re ready to enjoy it again, simply reheat your slice in the oven at 350°F for about 10-15 minutes until warmed through; this will help maintain that beautiful crispy texture.

If you prefer, a quick microwave warm-up works too, but know that you might lose some of that delightful crispiness on the edges. You can also freeze individual portions for a quick breakfast later; just wrap them tightly in plastic wrap before placing them in a freezer-safe container. They can be stored for up to two months, making them a perfect meal prep option.

Tips for Perfect Traditional French Toast Casserole

To help you achieve the best version of your Traditional French Toast Casserole, I’ve gathered some practical tips from my own kitchen adventures:

  • Don’t Rush the Soaking: Allowing the bread to soak for a good 10-15 minutes ensures every piece is saturated in that custard mixture, leading to an evenly flavored and textured dish.

  • Use Stale Bread: If possible, use slightly stale bread as it soaks up the custard nicely without becoming too mushy. If your bread is fresh, consider toasting it lightly to dry it out a bit before mixing.

  • Check for Doneness: If you’re unsure if it’s done, a quick poke in the center will help; if it springs back, it’s ready to be enjoyed.

  • Adjust Sweetness to Taste: Don’t hesitate to tweak the sugar level according to your preference—some prefer it sweeter, while others may like it more balanced with the savory components.

  • Explore Flavor Variations: Try adding chocolate chips, nuts, or dried fruits to the bread mixture for an added flavor kick!

Variations

Want to switch things up? Here are a few creative takes on the Traditional French Toast Casserole that will delight your palate:

  • Berry Burst: Fold in fresh or frozen berries (like blueberries or strawberries) into the bread mixture for a fresh, fruity twist.

  • Chocolate Delight: Add some semi-sweet chocolate chips to the bread mixture before pouring over the custard. The melted chocolate throughout the casserole adds an indulgent touch that’s hard to resist.

  • Savory Spin: Swap out sugar for salt, and add cooked bacon or sausage pieces to the bread mixture. This unexpected twist transforms it into a savory dish fit for any brunch.

  • Dairy-Free: Substitute almond milk or coconut milk in place of whole milk and use a dairy-free butter alternative to easily cater to those with dietary restrictions.

FAQs

Can I assemble this casserole a day in advance?
Absolutely! This casserole is perfect for prep ahead. Simply assemble it the night before, cover it tightly, and let it sit in the fridge overnight. Bake it in the morning for a quick, delicious breakfast.

What type of bread works best?
For the best texture and flavor, brioche or challah work wonderfully due to their richness. However, any thick-sliced bread will work if that’s what you have on hand!

Can I reheat leftovers?
Yes! If you have leftovers, they can be reheated in the oven at 350°F for around 10-15 minutes, which helps retain its crispy texture. You can also microwave a slice, but be mindful of the texture—it may lose some crispiness.

Can I freeze this casserole?
Yes! You can freeze assembled but unbaked casserole or baked leftovers. Wrap it tightly in plastic wrap and foil, storing it in the freezer for up to two months. When you’re ready to enjoy it, thaw overnight in the fridge and bake as instructed.
