Spring Brunch Strawberry Toast

My sister called on a Wednesday morning asking if I could handle brunch for twelve people on Sunday, and my first instinct was panic. Then I remembered this French toast bake—the kind of dish that sits quietly in the fridge overnight, asking for nothing but a drizzle of melted butter before it transforms into something golden and entirely foolproof. The brioche cubes drink in that custard like they've been waiting for it, and the strawberries turn glossy and wine-dark as they bake. It became my secret weapon that spring, and honestly, it's been my go-to ever since.

I made this for the first time on a chilly April morning when my partner's parents were visiting, and I'd spent the night before worrying about the timing. But standing in the kitchen at 8 a.m., watching the casserole come together in layers—bread, strawberries, bread, strawberries—something clicked. By the time it came out of the oven, the whole house smelled like cinnamon and caramelized sugar, and I realized I'd stopped checking the clock altogether.

Ingredients

• Brioche or challah, cut into 1-inch cubes (1 loaf, about 14 oz): Use day-old bread if you have it—it soaks up the custard without turning mushy, which is the whole magic here.
• Fresh strawberries, hulled and sliced (2 cups): Spring strawberries are worth seeking out at the farmers market; their tartness balances the sweetness of the custard perfectly.
• Large eggs (6): These are what transform the milk and cream into that silky, set custard that holds everything together.
• Whole milk (2 cups): Don't skimp on fat content—whole milk makes a difference in the final texture.
• Heavy cream (1/2 cup): This is what makes it feel special, like something served at a proper brunch rather than a weekday breakfast.
• Granulated sugar (1/2 cup): Sweetens the custard without overpowering the strawberries; adjust down slightly if your berries are particularly sweet.
• Pure vanilla extract (1 tbsp): Use real vanilla; the imitation kind leaves an odd aftertaste that lingers.
• Ground cinnamon (1 tsp): A humble spice that somehow makes everything taste more intentional and complete.
• Salt (1/4 tsp): This tiny amount deepens every other flavor without announcing itself.
• Unsalted butter, melted (2 tbsp): Drizzled over the top for richness and to help the almonds toast to a golden finish.
• Sliced almonds (1/3 cup): They add crunch and a subtle nuttiness that surprises people in the best way.
• Turbinado sugar or coarse sugar (2 tbsp): This crinkles and sparkles, giving a texture contrast and visual appeal that powdered sugar simply can't match.

Instructions

Prepare your dish:

Grease a 9x13-inch baking dish with butter or nonstick spray, making sure to coat the corners where the bread likes to stick. This small step saves so much frustration later.

Layer the bread and strawberries:

Arrange half of the bread cubes in an even layer, then scatter half the sliced strawberries over them. Repeat with the remaining bread and strawberries, creating a kind of casserole mosaic. The alternating layers help distribute the fruit and flavor throughout.

Whisk the custard:

In a large bowl, whisk together the eggs, milk, cream, sugar, vanilla, cinnamon, and salt until the mixture is smooth and the sugar has mostly dissolved. You want this to be completely homogeneous so every bite has the same delicate flavor.

Pour and soak:

Pour the custard evenly over the layered bread and strawberries, then gently press down on the bread with a spatula to encourage it to absorb the liquid. The bread will initially peek above the surface, but it will settle as it soaks.

Chill overnight (or at least 30 minutes):

Cover the dish and refrigerate for at least 30 minutes, though overnight is truly best—this gives the bread time to drink in the custard and allows the flavors to meld. I've found that the texture is noticeably more tender and cohesive after an overnight rest.

Preheat and prepare for baking:

When you're ready to bake, preheat the oven to 350°F. Remove the baking dish from the refrigerator and uncover it gently.

Add the finishing touches:

Drizzle the melted butter evenly over the top, then sprinkle the sliced almonds and turbinado sugar across the surface. These toppings will toast and caramelize, creating a beautiful golden crust.

Bake until golden:

Bake for 40–45 minutes, or until the top is a deep golden brown and the center is set but still slightly jiggly when you gently shake the dish. The edges will be more firm than the center, which is exactly how you want it.

Rest and serve:

Let the casserole rest for 10 minutes before slicing—this allows it to set just enough to hold its shape without being cold. Serve warm, with a drizzle of maple syrup or a light dusting of powdered sugar if you'd like.

There's something deeply satisfying about a dish that invites people to linger at the table, and this French toast bake does exactly that. My sister still texts me photos from family brunches where it's been served, and I love knowing that something I make in a quiet kitchen on a Saturday night becomes the centerpiece of someone else's joyful morning.

Make-Ahead Magic

The entire casserole can be assembled, covered, and refrigerated up to 24 hours before baking, which means you can handle almost all the work the day before. In the morning, you simply uncover it, add the topping, and bake—leaving you free to set the table, brew good coffee, or just breathe. I've also found that the overnight soak deepens the flavor and creates an even more luxurious texture, so it's not a shortcut—it's an actual improvement.

Flavor Variations to Explore

While strawberries are spring's gift, this base recipe adapts beautifully to what's in season. I've made it with fresh blueberries in early summer, swapped in raspberries when I found a good deal at the market, and even added white chocolate chips for a richer, more decadent version. The custard stays the same, but the fruit changes the entire personality of the dish.

Serving Suggestions & Small Details

Serve this warm with whipped cream, Greek yogurt, or a simple drizzle of real maple syrup for a brunch that feels completely put-together. If you're hosting, remember that this dish is forgiving about timing—it stays warm for a good 20 minutes after coming out of the oven, which takes the pressure off.

• A light sparkling wine or mimosa pairs beautifully with the sweetness and acidity of the strawberries.
• If you're watching allergens, check your brioche or challah labels, as some contain hidden dairy or nuts.
• Leftovers reheat gently in a 300°F oven for about 10 minutes, though honestly, this is the kind of thing people rarely leave behind.

This casserole has become my answer to the question of how to feed people well without losing your mind. It's the kind of recipe that asks you to trust the process, and it always delivers.
