Spring Brunch Strawberry Toast

There's something about spring that makes me want to fill a baking dish with bread and fruit and let the oven do the heavy lifting. My neighbor brought over a basket of strawberries one April morning, their green caps still dewy, and I suddenly remembered why French toast casserole exists: it's breakfast that feels like celebration without requiring you to stand at a stove. This baked version turned out to be the kind of dish that lets you sleep in, prep everything the night before, and still have something golden and fragrant waiting when guests arrive.

I made this for a small gathering last Mother's Day when a friend was visiting from out of town. We assembled it together the evening before, laughing about how we were basically making bread pudding's brunch cousin, and when it came out of the oven the next morning, the kitchen smelled like vanilla and caramelized butter. She cut into it, the custard jiggled slightly at the center, and everyone around the table went quiet for exactly the moment it takes to taste something that feels both elegant and comforting at once.

Ingredients

• Brioche or challah bread: This matters more than you'd think because soft, slightly sweet bread absorbs the custard without turning into mush, and the structure holds up beautifully through baking.
• Eggs, whole milk, and heavy cream: Together they create a custard that's rich enough to feel indulgent but not so heavy that people need to nap afterward.
• Vanilla extract and cinnamon: These aren't just flavoring; they're what makes the whole dish smell like springtime in your kitchen.
• Fresh strawberries: Hulled and sliced just before assembly so they stay bright red instead of turning dark around the edges.
• Cold butter, flour, and brown sugar topping: The crumb mixture should stay lumpy and coarse because those irregular pieces crisp up and catch the heat differently, giving you texture that matters.
• Powdered sugar and maple syrup: The finishing touches that turn this from good to the-kind-of-breakfast-people-remember.

Instructions

Set yourself up for success:

Preheat your oven to 175°C (350°F) and grease a 23x33 cm baking dish generously. Cut your bread into even 2.5 cm cubes so everything bakes at the same pace and soaks up the custard uniformly.

Build your layers:

Spread the bread cubes across the bottom of your dish, then scatter the sliced strawberries over them with a light hand so the fruit is distributed but not crowded. This gives the custard something to flow around and people something to look forward to in each bite.

Make the custard magic:

Whisk together six eggs, 480 ml milk, 120 ml heavy cream, 100 g sugar, 2 tsp vanilla, 1/4 tsp cinnamon, and 1/4 tsp salt in a large bowl until the mixture is smooth and pale. Pour it slowly and evenly over the bread and fruit, then gently press down with the back of a spoon so every piece of bread makes contact with the liquid.

Create the crumb topping:

In another bowl, mix 60 g flour, 50 g brown sugar, and 1/2 tsp cinnamon, then add 55 g cold cubed butter. Use your fingertips or a pastry cutter to work the butter in until the mixture looks like coarse, uneven crumbs; this is the part that matters because those lumps will crisp differently and give you layers of texture. Sprinkle this topping evenly across the entire surface.

Bake until golden:

Slide the dish into your preheated oven and bake for 40 to 45 minutes until the custard is set (it should jiggle just slightly at the very center when you gently shake the dish) and the top is golden brown. The kitchen will smell incredible about halfway through.

Rest and finish:

Let the casserole cool for 10 minutes so the custard firms up slightly and the temperature comes down to something you can actually eat. Dust with powdered sugar if you're feeling fancy, then serve warm with maple syrup drizzled over each slice.

Save

What surprised me most about this dish was how it became the thing people asked about instead of the thing they politely ate. One guest actually called the next week to ask if she could bring ingredients and make it at her own place, which felt like the highest possible compliment for a recipe you didn't invent yourself but simply assembled with a little care.

The Overnight Advantage

The best part of this casserole is that it actually improves when you assemble it the night before. The bread absorbs the custard mixture slowly while it sits in the cold fridge, meaning every cube is evenly soaked by morning instead of some pieces drinking eagerly and others staying dry. You wake up, preheat the oven, and in 45 minutes you have something that tastes like you've been planning it for weeks instead of something you threw together because you had guests coming.

Strawberry Variations and Substitutions

While strawberries are spectacular in spring, raspberries work beautifully here too, and blueberries add an unexpected earthiness that plays well with the vanilla. I've also tried a combination of strawberries and fresh mint scattered between the layers, which sounds fancy but is just a handful of torn leaves that give the whole thing a garden-fresh quality. The key is using fruit that won't turn the custard dark or add too much liquid, so berries are your safest bet.

Flavor Customizations and Pro Moves

If you want to elevate this beyond lovely into unforgettable, add 1 tsp of lemon zest to the custard mixture, which brightens everything without making it taste like lemon specifically. Some mornings I'll add a splash of almond extract to the custard, or fold in a few tablespoons of orange juice when I'm feeling like the dish needs a different mood. The basic formula is flexible enough to follow your instincts, and that's part of what makes it fun to make more than once.

• Toast the bread cubes lightly in the oven for 5 minutes before assembling if you want them to hold their shape even more stubbornly through baking.
• Make the crumb topping the day before and keep it in the fridge so it stays cold and crumbly until the moment you sprinkle it on.
• If the top is browning too quickly, drape a piece of foil loosely over the dish for the last 10 minutes of baking.

This is the kind of recipe that sits in your back pocket, waiting for the moment when you want to feed people something that tastes like care. Make it on a quiet spring morning and you'll understand why it keeps coming back to mind.
