Ingredients You’ll Need

The beauty of Overnight French Toast Casserole is how it transforms basic ingredients into something decadent. Every element, from the sturdy bread to the creamy custard, works together to deliver that irresistible texture and rich, warm flavor that makes this a breakfast favorite.

• French bread: Choose a loaf that’s a day or two old so it holds up to the custard soak without turning mushy.
• Large eggs: The eggs are the heart of the custard, binding everything together and providing luxurious richness.
• Whole milk: This adds moisture and creamy flavor, blending beautifully with the other dairy.
• Heavy cream: For extra decadence, the cream makes the casserole ultra luscious and tender.
• Granulated sugar: Balances the richness with subtle sweetness throughout the dish.
• Vanilla extract: A must for cozy, fragrant notes that make the casserole truly comforting.
• Ground cinnamon: Provides warmth and that classic French toast spice you crave.
• Salt: Just a pinch heightens all the other flavors and keeps the dish from tasting flat.
• Brown sugar: Forms a caramelized crust on top that’s simply unbeatable.
• Chopped pecans (optional): For a lovely nutty crunch; leave them out for a nut-free version.
• Unsalted butter: Melted butter makes the topping golden and adds a delicate richness.

How to Make Overnight French Toast Casserole

Step 1: Prep the Baking Dish and Bread

Start by greasing a 9×13-inch baking dish to ensure nothing sticks and cleanup stays easy. Then, cube your French bread into hearty, 1-inch chunks. Scatter them evenly in the dish—you want enough room for the custard to soak in around each piece. Using slightly stale bread works wonders here, helping absorb all of that lovely custard overnight while keeping the casserole’s texture toothsome.

Step 2: Make the Custard

In a large mixing bowl, whisk together the eggs, whole milk, heavy cream, granulated sugar, vanilla extract, ground cinnamon, and salt until everything is perfectly blended. This luscious mixture brings the signature flavor and creamy bite to your Overnight French Toast Casserole, so take a moment to make sure it’s mixed well with no streaks of egg.

Step 3: Soak the Bread

Pour the custard mixture evenly over the bread cubes in your prepared dish. Press down gently with a spatula or the back of a spoon so every cube gets a good soak—this helps achieve that creamy, almost bread pudding-like interior. Cover tightly with plastic wrap and let it work its magic in the fridge overnight. This rest is key for rich flavor and perfect texture in your finished casserole.

Step 4: Add the Topping

Come morning, take out the casserole and preheat your oven to 350°F (175°C). While the oven heats, mix together the brown sugar, optional chopped pecans, and melted unsalted butter. Sprinkle this mixture evenly over the soaked bread. The buttery, sugary topping caramelizes beautifully in the oven, giving your Overnight French Toast Casserole that signature golden crunch.

Step 5: Bake and Serve

Bake the casserole uncovered for 45 to 50 minutes, or until the top looks golden brown and the custard is set. The scent that fills your kitchen will be pure magic! Allow the casserole to rest for 5 to 10 minutes before serving; this helps it firm up a bit and makes for easier slicing. Then, just slice and enjoy—you’ve created a showstopping breakfast with minimal morning effort!

How to Serve Overnight French Toast Casserole

Garnishes

Dress up your Overnight French Toast Casserole with a sprinkle of powdered sugar, a drizzle of pure maple syrup, or a mountain of fresh berries. Each garnish brings a little something extra, from the subtle sweetness of the sugar to the fruity brightness of berries, making every bite truly special.

Side Dishes

Balance the richness of the casserole with lighter sides like crisp bacon, savory breakfast sausage, or a bowl of Greek yogurt and fruit. If you want to keep things on the wholesome side, a fresh fruit salad or a citrusy green salad pairs perfectly and makes your breakfast spread feel complete.

Creative Ways to Present

Try baking your casserole in individual ramekins for a personal touch or jazz it up for brunch parties by adding a homemade fruit compote. For holidays, you could sprinkle colorful sprinkles or edible flowers on top to add festive flair. However you serve it, this Overnight French Toast Casserole will always steal the show!

Make Ahead and Storage

Storing Leftovers

If you’re lucky enough to have leftovers, simply cover the dish tightly with foil or transfer portions to airtight containers. Store in the refrigerator for up to three days—the flavors continue to shine, and the texture stays delicious.

Freezing

To freeze Overnight French Toast Casserole, let it cool completely, then wrap individual portions or the whole casserole in plastic wrap and aluminum foil. It can be stored in the freezer for up to two months. Label and date for easy meal planning.

Reheating

To reheat, simply pop portions in the microwave until warmed through, or bake at 350°F (covered) until hot. A quick dash of maple syrup or fresh berries revives that just-baked flavor and freshens up each serving beautifully.

FAQs

Can I make this Overnight French Toast Casserole dairy-free?

Absolutely! Just swap the whole milk and heavy cream for your favorite plant-based alternatives, like almond or oat milk, and use dairy-free butter. The results are just as delicious and creamy.

Can I use a different type Breakfast

Definitely—try brioche or challah for a more decadent bite, or whole-grain bread for extra fiber. Sturdy breads work best to soak up the custard without getting soggy.

What if I forgot to refrigerate overnight?

If you’re in a rush, let it soak for at least 2 to 3 hours in the fridge, pressing down on the bread occasionally to help it absorb the custard. The overnight chill, though, really gives the best texture!

How do I prevent my casserole from becoming soggy?

Make sure to use slightly stale or day-old bread, and don’t skimp on the overnight soak. Baking uncovered also ensures the casserole bakes up with a golden, slightly crispy top.

Can I prepare the topping the night before?

You can! Just mix the brown sugar, pecans, and melted butter and store separately in the fridge. Sprinkle over the casserole just before baking for that perfect caramelized finish.
