Spring Brunch Strawberry French Toast

My sister called on a Thursday asking if I could bring something to her spring garden party, and without thinking, I said yes to a brunch dish for eight people. Standing in my kitchen at 6 AM on Saturday, I remembered seeing a golden baked French toast at a café years ago and thought, why not try that? What started as a rescue mission became something I now make every April—a casserole that somehow tastes both elegant and effortless, with strawberries peeking through custardy bread like little rubies.

I served this to my book club last May, and one of the women went quiet after her first bite—the good kind of quiet. She asked for the recipe right then and there, which meant more to me than any compliment because she was the one who always brought store-bought desserts. Now it shows up at her dinner parties too, and somehow that makes it feel like a small legacy I didn't know I was building.

Ingredients

• Brioche or challah bread: This is where the magic lives—it's rich enough to soak up the custard without falling apart, and it gets this golden exterior that tastes almost caramelized. Don't use everyday sandwich bread or you'll end up with something closer to bread pudding's sad cousin.
• Eggs, whole milk, and heavy cream: Together they create a custard that's silky but sturdy enough to hold the casserole together when you slice it; the cream makes it feel luxurious without being heavy.
• Granulated sugar and vanilla extract: The sugar dissolves into the custard and the vanilla hides in the background, letting the strawberries be themselves.
• Ground cinnamon: Use it in both the custard and topping for a warmth that somehow makes spring feel cozy.
• Fresh strawberries: Slice them the morning you bake if you can, because they stay juicier that way and the color doesn't fade into pink soup.
• Flour, brown sugar, and cold butter topping: This is the texture surprise—it bakes into a streusel that's crispy on the edges and tender inside, a detail that changes everything.
• Powdered sugar and maple syrup: The finishing touches feel like ceremony, but they're also delicious.

Instructions

Heat your oven and prepare the dish:

Set your oven to 175°C (350°F) and grease a 23x33 cm baking dish with butter or cooking spray. This is when your kitchen starts to smell like anticipation.

Layer the bread and strawberries:

Spread the bread cubes in an even layer across the bottom of your dish—don't pack them too tight—then scatter the sliced strawberries across the top like you're painting. The gaps between the bread are where the custard pools and does its transformative work.

Mix and pour the custard:

Whisk together the eggs, milk, cream, sugar, vanilla, cinnamon, and salt in a large bowl until the sugar dissolves and everything is pale and smooth. Pour it slowly over the bread, watching it sink into the gaps, then gently press down with the back of a spoon so every bread cube gets a chance to drink in the custard.

Make the crumbly topping:

In a medium bowl, toss together the flour, brown sugar, and cinnamon, then add the cold butter cubes and use your fingertips or a pastry cutter to work it into the mixture until it looks like coarse breadcrumbs. The cold butter is crucial—it creates those little pockets that turn crispy and golden in the oven.

Top and bake:

Sprinkle the crumbly mixture evenly over the entire casserole and slide it into the oven for 40 to 45 minutes until the top is burnished golden and the custard is set but still slightly jiggly in the very center. A knife inserted near the middle should come out with just a few moist crumbs.

Cool, finish, and serve:

Let it rest for 10 minutes so the custard sets fully and it becomes easy to cut into clean pieces. Dust generously with powdered sugar if you like, drizzle with warm maple syrup, and watch people's faces light up.

Save

There's something about a casserole that makes people feel taken care of, like someone spent real time thinking about their morning. This one does exactly that while barely requiring effort, which is the best kind of kitchen magic.

The Overnight Trick

The first time I made this the night before a brunch, I was nervous the bread would get soggy. Instead, the opposite happened—the custard soaked in evenly and the bread became this tender, almost cake-like texture that was somehow better than the same recipe baked fresh. Now I always prep it the evening before, and I think it's the secret reason people ask for seconds. You can also assemble it in the morning and let it sit at room temperature for an hour while your oven preheats, which gives the bread enough time to absorb the custard without the overnight wait.

Strawberries and Substitutions

I stick with fresh strawberries because they stay tart and bright against the sweet custard, but I've absolutely made this with raspberries in late summer when strawberries are expensive and sad. Blueberries work too, though they sink deeper into the casserole and you have to hunt for them a little, which is somehow charming. The flavor changes slightly with each berry, so you're not locked into one version—experiment and see which spring feels best in your kitchen.

Making It Your Own

This recipe is forgiving enough to welcome tweaks, and some of my favorite versions came from accidents or curiosity. I once added lemon zest to the custard on a whim because I had a lemon sitting on the counter, and it brightened everything in a way that made the strawberries taste more strawberry-like. You could dust the crumb topping with a tiny pinch of cardamom, or swirl a little almond extract into the custard if you want it to lean sweeter and more elegant. The base is sturdy enough to handle your creativity without falling apart.

• Toast your bread cubes lightly in a dry pan for five minutes before layering if you want extra texture and a deeper flavor.
• Add 1 teaspoon of lemon zest to the custard mixture for a subtle brightness that makes people ask what's in there.
• Let the assembled casserole sit at room temperature for an hour before baking to ensure the bread absorbs the custard evenly.

This casserole has become my answer to every spring gathering, and it never fails to make people feel welcomed and special. There's joy in sharing something warm and golden with the people you care about, and this recipe delivers that feeling every single time.
