With three kids and absolutely no time to stand flipping toast, this sweet breakfast bake came to my rescue and quickly became a beloved family tradition in our home.

French Toast Casserole is truly a game-changer, especially for those mornings when you want something cozy and impressive without the hassle. The first time I made it, I was a bit skeptical—wondering if soaking bread overnight would really make a difference—and oh, did it ever! The flavors melded beautifully, and the texture was like the perfect morning balance between custardy softness and golden crispiness. It’s like a baked French toast recipe but with way less fuss. If you’ve tried making traditional French toast and ended up juggling hot pans and eggs all at once, you’re not alone. This casserole came about from my own “aha” moment where I needed breakfast to be both tasty and hands-off.

Over the years, my French Toast Casserole has become my go-to for holiday breakfast casserole needs. I can prep it the night before, pop it in the oven while the kids get dressed, and by the time everyone’s at the table, magic is happening. Plus, it’s such a crowd-pleaser—from my pickiest eater to my in-laws. The smell alone draws everyone out of bed!

If you’ve never tried an easy French toast casserole like this, I promise you’re going to love how forgiving and delicious it is.

What You’ll Need for This French Toast Casserole

Before we get to the fun part of making this holiday breakfast casserole, let’s gather everything so that your French Toast Casserole turns out perfectly every time. I always use slightly stale bread—thick-cut brioche if I can find it—because it soaks up the custard without falling apart. When you’re shopping for ingredients for your French Toast Casserole, keep an eye out for good-quality vanilla extract and a cinnamon stick or ground cinnamon to give the dish that cozy, inviting flavor.

Ingredients for French Toast Casserole laid out on a kitchen counter

Here’s what my family loves in our French Toast Casserole:

  • 1 loaf of thick-cut brioche bread (about 12-14 ounces), cubed
  • 6 large eggs
  • 2 cups whole milk (or half and half for extra richness)
  • ½ cup granulated sugar
  • 1 tablespoon vanilla extract
  • 2 teaspoons ground cinnamon
  • ¼ teaspoon ground nutmeg (optional but magical)
  • Pinch of salt
  • Butter for greasing the baking dish and dotting on top
  • Powdered sugar and maple syrup, for serving

When making French Toast Casserole, you can find these ingredients easily at your local grocery store, but if you want to save some money, I recommend buying milk and eggs in bulk or at discount stores. Also, day-old bread is a great cost-saving hack for this recipe! And if you’re pressed for time, you can cube the bread a day ahead and store it in an airtight container.

Here’s a French Toast Casserole trick I learned that helped me: toast the bread cubes lightly before soaking them. It adds a bit of texture so the casserole isn’t soggy. Plus, greasing your pan with butter instead of cooking spray gives the casserole a beautiful golden crust that my kids always rave about.

Let’s Make This French Toast Casserole Together

Alright, it’s time for the fun — making this easy French toast casserole! Don’t worry if your first try isn’t perfect; I’ve had my share of mishaps, like soaking the bread too short or forgetting the cinnamon, but each time I learned more about what makes this baked French toast recipe really shine.

  1. Grease your baking dish thoroughly. I’ve found that butter works better than spray for that classic crispiness on the edges of the French Toast Casserole.
  2. Cube the bread and lightly toast if you want a little extra texture. You can do this in your oven at 350°F for about 5-7 minutes.
  3. Whisk together eggs, milk, sugar, vanilla, cinnamon, nutmeg, and salt in a large bowl. This custard base is what transforms your casserole into that sweet breakfast bake everyone loves.
  4. Add the toasted bread cubes to the custard mixture, gently folding until all pieces are soaked well. I like to let it sit for at least 10 minutes, but if you’re pressed for time, 5 minutes works too.
  5. Pour the mixture into your prepared baking dish. Dot the top with small pieces of butter. This gives your French Toast Casserole those irresistible golden pockets as it bakes.
  6. Cover loosely with foil and refrigerate overnight if you can. This overnight French toast bake step is what makes the flavors deepen and the texture perfect.
  7. When ready to bake, preheat your oven to 350°F (175°C). Take off the foil and bake for 35-45 minutes, or until the casserole is puffed and golden and the custard is set.
  8. Let it cool for 10 minutes before serving. Your kitchen should smell like a cozy bakery by now!

Finished French Toast Casserole in a baking dish, golden and inviting

In my kitchen, French Toast Casserole usually takes about 50 minutes from start to finish if you’re not doing the overnight soak, but prepping it the night before saves so much time on a busy morning. While the casserole is baking, I typically tidy up the kitchen or prepare some simple sides. Your French Toast Casserole should smell sweet and cinnamon-y — it’s the kind of scent that makes the whole house feel like a holiday morning.

If you want some additional tips or troubleshooting, Baked French Toast Recipe – Best Baked French Toast Casserole has wonderful pointers about getting the custard just right.

How I Love to Serve This French Toast Casserole

Once your French Toast Casserole is out of the oven, the fun really begins! My family loves this French Toast Casserole served piping hot with a dusting of powdered sugar and plenty of maple syrup on hand. It’s a sweet breakfast bake that instantly cheers up everyone’s morning and pairs perfectly with fresh fruit or crispy bacon if you like a bit of savory to balance the sweetness.

During holidays, this French Toast Casserole becomes my go-to — I make it alongside my Southern Squash Casserole or Cheesy Green Bean Casserole to round out the meal with hearty sides. It’s perfect for Christmas morning, Easter brunch, or even lazy Sunday breakfasts when the whole family wants something comforting and shareable.

If I’m hosting guests, I like to present the casserole in a nice ceramic dish with a sprig of fresh mint or a dusting of cinnamon on top — it makes the sweet breakfast bake feel a bit more festive. And here’s a tip: If you have extra French Toast Casserole, just wrap individual portions tightly and refrigerate — they reheat beautifully in the microwave or oven.

I’ve even tried seasonal twists like adding chopped apples or a drizzle of caramel sauce, turning this simple baked French toast recipe into a fall-friendly treat.

Your French Toast Casserole Questions Answered

Let’s chat about some of the common questions I get about French Toast Casserole — I’ve learned so much from both my family’s feedback and my kitchen experiments.

Q1: Can I use gluten-free bread for French Toast Casserole?
Absolutely! I’ve switched to gluten-free bread for a family member before, and it works well as long as the bread is dense enough to soak the custard without crumbling.

Q2: How long can I keep an overnight French toast bake in the fridge?
Up to 24 hours is perfect. I’ve found that beyond that, the bread starts slipping too much and the texture changes. It’s best fresh for that tender, custardy combo.

Q3: Can I prepare French Toast Casserole in the morning without soaking overnight?
You sure can! Just increase your soaking time to about 20-30 minutes so the bread can absorb well. Sometimes I do this if I’m running late.

Q4: What’s the best bread for French Toast Casserole?
I’m partial to brioche or challah for their soft, rich texture. But day-old French bread or even croissants can be great. Just avoid very soft, pre-sliced sandwich bread for this recipe.

Q5: How do I keep my French Toast Casserole from getting soggy?
Lightly toasting your bread cubes before soaking, and dotting butter on top before baking help a lot. I learned the hard way that skipping these steps makes the casserole too wet.

Q6: Can I make French Toast Casserole dairy-free?
Yes! Use almond, oat, or coconut milk and a vegan butter substitute. I’ve tested this tweak for friends with allergies, and it still bakes up beautifully.

Q7: What’s a good shortcut when making this French toast casserole when time is tight?
Pre-cut your bread and mix your custard the night before, then assemble and bake in the morning. I also recommend watching French Toast Casserole (Overnight) – Fresh April Flours — she has some wonderful prep shortcuts.
