Ingredients You’ll Need

What truly sets this French Toast Casserole Recipe apart is its simple yet perfectly balanced ingredients. Each element is thoughtfully chosen—some delivering luscious richness, others adding texture or that delicately spiced aroma. Here’s what you’ll need and why it matters.

• Sourdough bread (or brioche, challah, or French): Sturdy, flavorful bread cubes soak up the custard without falling apart—slightly stale works best for absorbing flavors!
• Eggs: Eight large eggs create a creamy, rich base, binding the whole casserole together.
• Milk: Two cups of milk ensure the custard mixture is smooth and not overly heavy.
• Heavy cream: A half-cup adds a luxurious silkiness you can taste in every bite.
• Vanilla extract: One tablespoon for that irresistible, nostalgic vanilla warmth.
• Sugar: Three-quarters cup sweetens the custard just right—never overwhelming.
• All-purpose flour: Half a cup is the secret to a crunchy, golden topping.
• Packed light brown sugar: Adds deep, caramel-like notes to the crumble topping.
• Ground cinnamon: A teaspoon weaves a sweet-spicy aroma through every bite.
• Salt: Just a quarter teaspoon heightens flavors and balances the sweetness.
• Cold unsalted butter: Incorporate half a cup, cut into pieces, to make the topping perfectly crumbly and rich.

How to Make French Toast Casserole Recipe

Step 1: Prep the Bread

Start by cutting your chosen bread—sourdough, brioche, challah, or French—into roughly 1-inch cubes. You want generous, chunky pieces that soak up the custard but still hold their shape. Spread them evenly in a well-greased 9-by-13-inch baking dish, making sure every inch is covered. This hearty base is about to transform into something magical!

Step 2: Mix the Custard

In a medium bowl, whisk together the eggs, milk, heavy cream, vanilla extract, and sugar. Take a moment to make sure everything is well combined—the smoother the custard, the silkier your French Toast Casserole Recipe will be! Pour this luscious mixture evenly over the bread. You’ll see it soaking into every nook and cranny, promising flavor in every bite.

Step 3: Chill and Let the Flavors Mingle

Cover the whole baking dish with plastic wrap and refrigerate for a minimum of 4 hours, or overnight if possible. This patience pays off—the bread absorbs every bit of that custardy goodness, resulting in a dish that’s creamy in the center and perfectly set.

Step 4: Prepare the Crumble Topping

Grab a new bowl and stir together the flour, packed brown sugar, ground cinnamon, and salt. Dot the cold butter into this mixture, then cut it in with a fork or pastry blender until you get pea-sized crumbles. For easy morning assembly, pop the topping in a plastic bag and chill in the fridge overnight next to your casserole.

Step 5: Preheat and Assemble

When you’re ready to bake, preheat your oven to 350 degrees F. Unwrap the casserole dish and evenly scatter the crumbly cinnamon topping right over the bread. This is where the magic really starts—every bite gets a sweet, buttery crunch on top.

Step 6: Bake to Golden Perfection

Slide the casserole into the oven, uncovered, and bake for 45 to 60 minutes. If you love it a little softer and custardier, check around the 45-minute mark. For a firmer, bakery-style texture, let it bake a bit longer. When it’s puffed and beautifully browned on top, it’s ready to serve!

How to Serve French Toast Casserole Recipe

Garnishes

A warm French Toast Casserole Recipe just begs to be finished with a sprinkle of love. Try topping it with a dusting of powdered sugar, a handful of fresh berries, or even a drizzle of pure maple syrup. For something special, a dollop of whipped cream or a sprinkle of toasted nuts gives beautiful flavor and color.

Side Dishes

While this casserole shines on its own, it pairs wonderfully with a bright fruit salad, smoky bacon, or savory breakfast sausage to balance its sweetness. If you’re serving a crowd, consider a platter of scrambled eggs or roasted potatoes as a hearty addition.

Creative Ways to Present

Turn brunch into an occasion by serving individual squares in small bowls with toppings set out for a “build your own” bar. Or, stack slices on a serving platter and garnish with edible flowers or mint leaves. For a charming touch, gently reheat and pack slices to-go for a picnic breakfast in the park.

Make Ahead and Storage

Storing Leftovers

If you find yourself with extra servings of this French Toast Casserole Recipe, simply let it cool to room temperature, then cover the dish tightly or transfer slices to an airtight container. Refrigerate for up to four days—it reheats beautifully, making mornings a breeze!

Freezing

This dish is freezer-friendly! After baking and cooling completely, wrap individual portions or the entire casserole securely in plastic wrap and foil. Freeze for up to two months. When you’re ready to enjoy, thaw overnight in the fridge for the best texture.

Reheating

For best results, reheat slices in a 350 degree F oven (cover with foil to prevent drying out) until warmed through, about 15-20 minutes. If you’re short on time, a microwave works, too—just keep an eye out so it doesn’t overcook. The flavors and texture are just as inviting the second time around!

FAQs

Can I use gluten-free bread for this French Toast Casserole Recipe?

Yes, you can! Just choose your favorite sturdy, gluten-free loaf. The key is making sure the cubes are hearty enough to absorb the custard without turning mushy, so slightly stale gluten-free bread is ideal.

Can I make the French Toast Casserole Recipe dairy-free?

Absolutely! Substitute your favorite dairy-free milk (like almond, oat, or coconut milk) and use coconut cream instead of heavy cream. Swap out the butter for a quality vegan alternative for the topping, and you’re set.

Can I assemble the casserole ahead and bake it later?

That’s one of the best parts! You can assemble the entire casserole—with the topping stored separately—up to 24 hours in advance. Store it all in the fridge, then sprinkle on the topping and bake whenever you’re ready.

What bread works best for this French Toast Casserole Recipe?

You can’t go wrong with sourdough, brioche, challah, or French bread. The loaf should be a little stale for maximum soak-ability and hold up to baking—skip soft sandwich bread for best results.

Can I add fruit or other mix-ins?

Definitely! Blueberries, diced apples, or even small chunks of cream cheese are delicious folded into the bread before pouring on the custard. Just take care not to overload—about a cup of add-ins is perfect for this recipe.
