Ingredients You’ll Need

The beauty of this Baked French Toast Casserole lies in its simplicity—classic ingredients come together to form layers of flavor and texture you’ll crave. Here are the essentials that turn pantry staples into your new favorite breakfast bake.

• French bread: Day-old bread works best here; its sturdy texture soaks up the custard without turning soggy, ensuring fluffy yet substantial bites in every serving.
• Large eggs: These provide the rich structure for the custard, binding everything together as it bakes.
• Whole milk: Adds a creamy base that soaks all the way through each bread cube.
• Heavy cream: This extra dose of dairy takes the custard to an ultra-luxurious place.
• Granulated sugar: Brings classic sweetness to the custard layer.
• Brown sugar: Used in both the custard and topping for a molasses-kissed depth of flavor.
• Vanilla extract: A splash of vanilla amplifies the cozy, bakery-fresh aroma.
• Ground cinnamon: Essential for that classic French toast taste and warm color.
• Ground nutmeg: Just a pinch brings a subtle, nutty warmth that makes the casserole special.
• Salt: Enhances everything else—don’t skip it!
• All-purpose flour (for topping): Helps create the crumbly texture on top.
• Unsalted butter (for topping): Cold cubes separate into perfect buttery pockets as the casserole bakes.

How to Make Baked French Toast Casserole

Step 1: Prep the Baking Dish and Bread

Start by greasing a 9×13-inch baking dish—nothing fancy, just a good coat of butter or nonstick spray so that glorious, custard-soaked bread doesn’t stick. Spread the bread cubes evenly in the dish, letting them tumble into every corner. Day-old bread is key here; it absorbs more custard and bakes up golden on top, but tender throughout.

Step 2: Whisk Together the Custard

In a large bowl, whisk together the eggs, milk, heavy cream, granulated sugar, brown sugar, vanilla extract, cinnamon, nutmeg, and salt. This fragrant mixture is the backbone of your Baked French Toast Casserole, creating a creamy base that seeps into each piece of bread.

Step 3: Soak the Bread

Pour the custard evenly over the bread cubes. Don’t be afraid to give the bread a gentle press with your hands or a spatula, ensuring every cube is well-soaked. Cover the dish tightly and refrigerate overnight, or at least four hours. This chill time is where the magic happens—the bread absorbs all that luscious custard, ensuring flavor in every bite.

Step 4: Add the Buttery Streusel Topping

When you’re ready to bake, preheat your oven and pull the casserole from the fridge. For the topping, mix flour, brown sugar, cinnamon, and salt together in a bowl. Add cold, cubed butter and work it in with a pastry cutter or your fingertips until coarse crumbs form. Sprinkle this delightful crumble evenly over the soaked bread. The topping bakes up into crunchy, golden pockets that contrast perfectly with the soft custard beneath.

Step 5: Bake Until Golden

Bake at 350°F (175°C) for 45 to 50 minutes. The top should be deeply golden and crisp, the center just set. Your kitchen will fill with the scent of cinnamon and caramelized brown sugar—a sure sign that brunch is almost ready. Let the dish cool for just a few minutes before serving.

How to Serve Baked French Toast Casserole

Garnishes

The finishing touches are half the fun! Dust your Baked French Toast Casserole with a drift of powdered sugar, drizzle generously with warm maple syrup, or scatter a handful of fresh berries over the bubbling top. A dollop of whipped cream or a sprinkle of toasted nuts adds a lovely contrast to each soft bite.

Side Dishes

This casserole is a meal in itself, but a simple side of scrambled eggs, fresh fruit salad, or crispy bacon rounds out the breakfast table, making it a full-on feast. It’s perfect for holidays or any weekend when you want to treat yourself or delight a crowd.

Creative Ways to Present

Try baking individual portions in ramekins for a festive brunch spread, or slice the cooled casserole into neat squares for an easy-to-serve breakfast buffet. You can even turn leftovers into a decadent dessert—just add a scoop of ice cream and a drizzle of caramel sauce for pure indulgence.

Make Ahead and Storage

Storing Leftovers

If you’re lucky enough to have leftovers, let the casserole cool to room temperature before covering with foil or transferring to an airtight container. Store in the refrigerator for up to three days. The flavors deepen and the custard sets even more, making it delicious reheated the next morning.

Freezing

Baked French Toast Casserole freezes beautifully. For best results, wrap individual pieces or the entire casserole (once cooled) tightly in plastic wrap and foil. Freeze for up to two months. To thaw, simply transfer to the refrigerator overnight.

Reheating

Warm leftovers, uncovered, in a 350°F (175°C) oven for about 15 to 20 minutes until heated through. For single servings, a quick zap in the microwave works, but the oven brings back that irresistible topping crunch. Add a little syrup or a splash of milk if it looks dry after chilling.

FAQs

Can I use different types of bread for Baked French Toast Casserole?

Absolutely! While French bread is a classic choice because of its sturdy crumb, you can use brioche, challah, or sourdough for a twist. Softer breads will soak up the custard more, resulting in a silkier texture.

How far ahead can I assemble the casserole?

You can assemble Baked French Toast Casserole up to 24 hours ahead. In fact, the longer it sits (within reason), the more flavorful and custardy it becomes. Just make sure to keep it covered and refrigerated until baking.

Is it possible to make this recipe dairy-free?

Yes, you can substitute non-dairy milk (like almond or oat) and use coconut cream or a plant-based creamer in place of heavy cream. Swap in vegan butter for the topping, and you’ll still get a fabulous result.

Can I add fruit or nuts to the casserole?

Of course! Layer in chopped apples, blueberries, or raspberries between the bread cubes before adding the custard, or sprinkle chopped pecans or walnuts into the topping for some extra crunch and richness.

What if I don’t have time to let the casserole soak overnight?

If you’re pressed for time, you can soak the casserole for as little as four hours, though overnight gives the best flavor and texture. Even a shorter soak will yield a tasty result—just press the bread down to help it absorb more custard quickly.

Final Thoughts

There’s something downright magical about Baked French Toast Casserole—a make-ahead wonder that feels both homey and special. Whether for brunch with friends or a cozy family breakfast, give yourself (and your loved ones) the gift of a dish that’s as easy as it is unforgettable. Go ahead, give it a try—your kitchen might just become everyone’s favorite brunch spot!
