Ingredients You'll Need
Great French toast casserole lives or dies by the bread. Seek out a loaf that’s sturdy enough to hold its shape after a night in custard yet tender enough to meld into the filling. My first choice is day-old brioche—its buttery crumb soaks like a dream—but challah or even a country white works. Avoid pre-sliced sandwich bread; it turns gummy. Cut the loaf into 1-inch cubes; this size traps pockets of custard without collapsing.
For the custard, I whisk together whole eggs, egg yolks, whole milk, and a splash of cream. The extra yolks lend richness reminiscent of melted ice cream. Maple syrup sweetens gently, while brown sugar deepens flavor. Vanilla extract is non-negotiable, and orange zest wakes everything up. A pinch of salt balances sweetness, and cardamom adds intrigue without stealing the show.
The topping is where texture magic happens. Cold butter, brown sugar, flour, and cinnamon combine into pebbly streusel. Candied pecans—homemade or store-bought—scatter across for crunch. If you’re nut-free, swap in pumpkin seeds or simply double the streusel.
Finally, serve with warm maple syrup, fresh berries, and a snowfall of powdered sugar. A dollop of orange-cardamom whipped cream catapults it into celebratory territory.
How to Make New Year's Brunch French Toast Casserole Bake
Prep Your Pan & Bread
Butter a 9×13-inch baking dish. Cube brioche into 1-inch pieces; you need roughly 12 packed cups. Stale bread is ideal—if yours is fresh, spread cubes on a rimmed sheet and bake at 250 °F for 20 minutes to dry slightly.
Whisk the Custard
In a large bowl, whisk 6 large eggs plus 4 egg yolks until homogenous. Whisk in 2 cups whole milk, 1 cup heavy cream, ½ cup maple syrup, ⅓ cup packed brown sugar, 2 tsp vanilla, 1 tsp orange zest, 1 tsp cinnamon, ½ tsp cardamom, and ½ tsp kosher salt. The mixture should be silky and fragrant.
Combine & Press
Add bread cubes to the custard and fold gently until every piece is coated. Pour into the buttered dish. Press down with a spatula so the top layer is level and mostly submerged. Cover tightly with foil and refrigerate at least 4 hours or up to 24.
Make the Streusel
In a medium bowl, combine ½ cup flour, ½ cup brown sugar, 1 tsp cinnamon, and ¼ tsp salt. Cut in ½ cup cold unsalted butter until pea-size crumbs form. Stir in ½ cup candied pecans. Refrigerate in a zip-top bag until ready to bake.
The Morning Of: Bring to Room Temp
Remove casserole from fridge 30 minutes before baking. Cold dish + hot oven = cracked bakeware. Meanwhile, preheat oven to 350 °F (175 °C) with rack in center.
Top & Bake
Sprinkle chilled streusel evenly over the soaked bread. Bake uncovered 40 minutes, until puffed and golden. If the top browns too quickly, tent loosely with foil for the final 10 minutes. A knife inserted near the center should come out with just a few moist crumbs.
Rest & Serve
Let stand 10 minutes to set the custard. Dust with powdered sugar, scatter fresh berries, and bring the whole pan to the table with warm maple syrup. Watch it disappear.
Expert Tips
Temp Check
An instant-read thermometer should register 190 °F in the center—any higher and custard squeezes out.
Overnight Magic
The full 24-hour soak yields bakery-level cohesion; don’t short-change the chill.
Dairy Swaps
Half-and-half works in a pinch, but avoid skim milk—casserole needs fat for richness.
Freezer Friendly
Bake, cool, cut into squares, and freeze individually. Reheat at 300 °F for 15 minutes.
Variations to Try
- Bourbon-Peach: Fold 1 cup frozen peaches into bread cubes; replace 2 Tbsp milk with bourbon.
- Chocolate Hazelnut: Add ½ cup Nutella dollops and ½ cup chopped hazelnuts to streusel.
- Eggnog Spice: Swap milk/cream for 3 cups eggnog and add ¼ tsp nutmeg.
- Savory-Sweet: Reduce sugar by half, add 1 cup crispy bacon and ½ cup grated sharp cheddar.
Storage Tips
Refrigerator: Cool completely, cover with foil, and refrigerate up to 4 days. Reheat squares in a 300 °F oven for 12–15 minutes or microwave 45–60 seconds.
Freezer: Wrap individual portions in plastic then foil; freeze up to 2 months. Thaw overnight in fridge before reheating.
Make-Ahead: You can prep through Step 3 up to 24 hours ahead. If you need longer, freeze the unbaked casserole (without streusel) for up to 1 month. Thaw overnight, add topping, and bake as directed.
