Spring Brunch Strawberry French Toast

There's something about spring that makes me want to feed people without much fuss, and this strawberry French toast bake became my answer to that impulse. My sister called one Saturday morning asking if I could handle brunch for eight, and instead of panicking, I remembered this casserole—the kind you assemble the night before and slide into the oven while everyone's still in their pajamas. The brioche soaks up all that custardy goodness, the strawberries bleed their sweetness throughout, and somehow it feels both effortless and impressive.

I'll never forget pulling this out of the oven that first time my sister tasted it—her face went quiet for a second, then she asked for seconds before finishing her first piece. That's when I knew this wasn't just another brunch recipe; it was the kind of dish that makes people linger at the table longer, pouring more coffee, lingering over conversation instead of rushing off.

Ingredients

• Brioche or challah (1 loaf, about 14 oz / 400 g), cut into 1-inch cubes: Day-old bread is genuinely better here because it's slightly firmer and soaks up the custard without turning into mush; if you only have fresh bread, let it sit out for a few hours or lightly toast the cubes first.
• Fresh strawberries (2 cups / 300 g), hulled and sliced: The tartness balances all that rich custard, and I learned to use strawberries that are ripe but not mushy, or they'll dissolve into the casserole and disappear.
• Large eggs (6): These bind everything together and give you that silky custard layer that makes this dish special.
• Whole milk (2 cups / 480 ml): This is your base; it keeps things from becoming too heavy or dense.
• Heavy cream (1/2 cup / 120 ml): The secret to that luxurious texture that makes people pause mid-bite.
• Granulated sugar (1/2 cup / 100 g): Balance this with the tartness of the berries and the richness of the dairy.
• Pure vanilla extract (1 tbsp): Don't skip this or use imitation; the quality makes a noticeable difference in how the whole thing tastes.
• Ground cinnamon (1 tsp): A gentle spice that whispers rather than shouts, pulling warmth from the custard.
• Salt (1/4 tsp): This tiny amount amplifies all the other flavors without announcing itself.
• Unsalted butter, melted (2 tbsp / 30 g): For drizzling over the top before baking to help toast everything.
• Sliced almonds (1/3 cup / 40 g): They add crunch and a subtle nuttiness that contrasts beautifully with the soft interior.
• Turbinado or coarse sugar (2 tbsp / 25 g): This doesn't melt completely, so it stays crunchy and catches the light on top.

Instructions

Prepare your baking dish:

Grease a 9x13-inch baking dish with butter or nonstick spray, making sure you get into the corners and all the way up the sides so nothing sticks.

Layer the bread and strawberries:

Arrange half of your bread cubes in an even layer across the bottom, then scatter half the strawberry slices over top. Repeat with the remaining bread and berries so you have two distinct layers. Don't pack it too tightly; the custard needs room to move through.

Mix the custard:

In a large bowl, whisk together the eggs, milk, cream, sugar, vanilla, cinnamon, and salt until everything is smooth and there are no streaks of egg white visible. This should take about a minute of steady whisking.

Pour and soak:

Pour the custard mixture slowly over the bread and berries, then gently press down with the back of a spoon or a spatula to help the bread soak up as much liquid as possible. You want it moistened but not swimming.

Chill overnight:

Cover the dish with plastic wrap and refrigerate for at least 30 minutes, though overnight is genuinely worth it because the bread keeps absorbing custard and the flavors get to know each other.

Prepare to bake:

Remove the dish from the refrigerator about 15 minutes before you plan to bake, preheat your oven to 350°F (175°C), and uncover the casserole.

Top and bake:

Drizzle melted butter over the surface, then scatter the almonds evenly, finishing with a sprinkle of turbinado sugar. Bake for 40–45 minutes, until the top is golden brown and a knife inserted in the center comes out clean or just slightly custard-y.

Rest and serve:

Let the casserole sit for 10 minutes after coming out of the oven; this lets the custard set up a bit so you can get clean slices. Serve warm, drizzled with maple syrup or dusted with powdered sugar if you're feeling fancy.

Save

There was one Easter morning when I made this for my neighbors, and we ended up sitting on the porch for three hours just talking, this casserole somehow the permission we all needed to slow down. Food can do that sometimes—it creates the space for people to actually be together instead of just coexisting.

Why Overnight Chilling Actually Matters

The first time I tried to bake this the same day I assembled it, the bread hadn't fully absorbed the custard and the whole thing felt disjointed—custardy in some spots, dry in others. Overnight chilling lets every piece of bread drink up that custard mixture, so when it hits the oven, it's already unified and ready to transform into something creamy and rich. I've also discovered that if you're really pressed for time, even two hours helps considerably, but overnight is the sweet spot where the bread becomes almost like a sponge cake soaked in cream.

Seasonal Variations That Actually Work

Spring isn't the only time for this dish—I've made it in summer with raspberries, in fall with sliced peaches swapped for strawberries, and once even added white chocolate chips in winter when I was feeling decadent. The beauty of this casserole is that it adapts happily to whatever fruit is good right now in your part of the world. Just keep the ratio roughly the same, and you'll land somewhere delicious every time, though I learned not to use frozen berries unless you thaw and drain them first, or you'll end up with extra liquid in the custard that throws off the texture.

Make-Ahead Strategy and Serving Ideas

This is genuinely one of the most forgiving dishes for entertaining because you can assemble it up to two days ahead, which means almost no stress the morning of brunch. I've also discovered that leftovers keep beautifully in the fridge for three or four days—just cover them loosely and reheat gently in a 300°F oven for about 15 minutes if you want them warm again. Some people swear by serving it with whipped cream or vanilla yogurt, and I've taken to having both on the table so people can choose their own adventure.

• Make it two days ahead and simply bake it fresh the morning you need it, or bake it fully and reheat gently wrapped in foil.
• A light sparkling wine or mimosa next to each place setting makes this feel like celebration instead of just breakfast.
• Leftovers are honestly better than the original in my opinion—the flavors deepen and everything gets even more custardy.

This casserole has become my go-to when I want to feed people without stress, and it never fails to make a moment feel special. There's something generous about a dish that tastes this good and asks so little of you in return.
