Spoon-tender custard-soaked bread, a crunchy buttery streusel on top, and that warm maple syrup drizzle that makes everything feel like a celebration — that’s baked French toast casserole in a nutshell. It’s the easiest way to feed a crowd at brunch, stretch a loaf of day-old brioche, and get ahead by assembling the night before. If you like make-ahead, crowd-pleasing casseroles, you might also enjoy this savory baked cream cheese spaghetti casserole that’s similarly built for easy reheating and big appetites.
Why you’ll love this dish
This casserole takes classic French toast flavors and turns them into a hands-off, forkable centerpiece. Instead of standing over the griddle flipping slices, you cube the bread, pour a cinnamon-vanilla custard over it, and let refrigeration do the work. The optional orange juice brightens the custard, and the brown-sugar-butter topping crisps into a crumble that guests will fight over.
“We assembled this the night before and everyone still raved the next morning—golden top, moist interior, and the maple syrup made it feel holiday-ready.” — a regular brunch guest
Reasons to try it:
- Make-ahead convenience: assemble and chill overnight.
- Feeds a crowd: a 9×13 pan serves 8–10 easily.
- Flexible: switch bread, milk, or topping to suit tastes or dietary needs.
- Kid-approved: sweet, tender, and easy to serve.
The cooking process explained
Before you pull out the pans, here’s the simple flow so you know what to expect:
- Cube day-old brioche or French bread for the best texture. Fresh bread can become soggy.
- Whisk eggs, milk, sugar, cinnamon, vanilla, and optional orange juice into a smooth custard.
- Toss the bread with the custard, transfer to a greased 9×13 pan, then chill 2 hours or overnight so the custard fully soaks in.
- Stir together the buttery topping. Spoon it over the chilled bread before baking.
- Bake 35–45 minutes until the top is golden and the custard is set (center should be mostly firm with a slight jiggle).
- Rest 10 minutes, then dust with powdered sugar and drizzle with warm maple syrup.
This overview helps you time other brunch elements—fruit, coffee, and any savory sides—so everything hits the table hot.
What you’ll need
- 1 loaf brioche or French bread, cut or torn into 1–2 inch cubes (day-old preferred)
- 8 large eggs
- 1 1/2 cups milk (whole milk for richness; 2% works too)
- 2 tsp ground cinnamon
- 1 tbsp vanilla extract
- 1/4 cup granulated sugar
- 1/2 tbsp orange juice (optional; adds brightness)
- 4 tbsp unsalted butter, melted (for topping)
- 2 tbsp light brown sugar (topping)
- 1 tbsp granulated sugar (topping)
- 1 tsp ground cinnamon (topping)
- 1/8 tsp salt (topping)
- Maple syrup and powdered sugar, for serving
Substitutions/notes:
- Use half-and-half or a mix of milk and cream for an extra-rich custard.
- For a dairy-free version, swap in unsweetened almond or oat milk and use a vegan butter for the topping.
- If using salted butter in the topping, reduce or omit the 1/8 tsp salt.
Step-by-step instructions
- Preheat the oven to 375°F (190°C). Spray a 9×13-inch baking dish with non-stick cooking spray.
- Cut or tear the loaf into 1–2 inch cubes. Place the cubes in a large mixing bowl.
- In a separate bowl, whisk together 8 eggs, 1 1/2 cups milk, 1/4 cup granulated sugar, 2 tsp cinnamon, 1 tbsp vanilla extract, and 1/2 tbsp orange juice (if using). Whisk until smooth and slightly frothy.
- Pour the custard over the bread cubes. Toss gently with a spatula or your hands until most pieces are coated. Transfer the mixture to the prepared baking dish, pressing lightly so pieces settle evenly.
- Cover the dish tightly with plastic wrap or foil and refrigerate for at least 2 hours or up to overnight to let the custard fully penetrate the bread.
- While chilling, prepare the topping: in a small bowl, combine 4 tbsp melted unsalted butter, 2 tbsp light brown sugar, 1 tbsp granulated sugar, 1 tsp cinnamon, and 1/8 tsp salt until evenly mixed.
- After chilling, remove the casserole from the fridge. Spoon the topping evenly over the surface—don’t worry about complete coverage; the topping will spread and caramelize as it bakes.
- Bake for 35–45 minutes, or until the top is golden brown and the center is set (the middle should no longer be liquid and will have a slight jiggle). If you have an instant-read thermometer, aim for about 160°F in the center for safe egg cooking.
- Let the casserole rest 10 minutes before serving. Dust with powdered sugar and offer warm maple syrup for drizzling.
Safety tip: Don’t leave custard-based dishes at room temperature for more than 2 hours; refrigerate promptly.
Best ways to enjoy it
Serve slices warm on plates with a dusting of powdered sugar and a warm drizzle of pure maple syrup. Pair with:
- Fresh fruit: berries, sliced oranges, or a lightly macerated fruit salad to cut the sweetness.
- Protein: crispy bacon, breakfast sausage, or a frittata for a balanced spread.
- Beverage pairing: freshly brewed coffee, a rich latte, or sparkling mimosas for celebrations.

Storage and reheating tips
- Refrigeration: Cool to room temperature (no more than 2 hours), cover tightly, and refrigerate. Keeps 3–4 days.
- Freezing: Cut into portions, wrap tightly in plastic and foil, or place in airtight containers. Freeze up to 2 months. Thaw overnight in the fridge before reheating.
- Reheating (oven): Preheat to 325°F (160°C). Cover with foil and warm 15–20 minutes for a single portion or 25–35 minutes for a full pan, until heated through. Remove foil for the last 5–10 minutes if you want to crisp the top.
- Reheating (microwave): For single servings, microwave on medium power in 30‑second intervals to avoid rubbery texture; total time will vary by microwave. Let rest 1 minute before serving.
Label frozen portions with date and contents for best practice.
Pro chef tips
- Day-old bread matters: Slightly stale bread absorbs custard better without falling apart. If your bread is fresh, dry cubes on a baking sheet at 300°F for 10–12 minutes.
- Don’t over-sog—let it chill: Refrigerating 2–12 hours is key; shorter times give less soak, longer gives a more uniform custard interior.
- Toppings are flexible: For a streusel effect, pulse 1/3 cup oats + 1/3 cup flour + 3 tbsp cold cubed butter + 2 tbsp brown sugar in a food processor. Sprinkle before baking.
- Test for doneness: The center should be set and not watery. Use an instant-read thermometer (160°F recommended) if unsure.
- Even browning: If the edges brown faster than the middle, loosely tent foil over the pan for the last 10–15 minutes.
Creative twists
- Berry-almond version: Fold 1 cup fresh or frozen berries into the soaked bread and sprinkle sliced almonds over the topping.
- Citrus-cardamom: Swap cinnamon for 1 1/2 tsp ground cardamom and omit orange juice, then finish with orange zest.
- Maple-pecan crunch: Mix chopped pecans into the topping for an extra crunch that pairs perfectly with syrup.
- Savory-sweet: Omit the brown sugar topping, add crumbled bacon into the custard, and sprinkle chopped chives after baking for a brunch hybrid.
- Vegan: Use firm cubed challah made with plant-based ingredients, combine silken tofu blended with non-dairy milk and maple syrup as the custard, and use vegan butter for topping.
Common questions
Q: Can I use fresh bread instead of day-old?
A: Yes, but fresh bread soaks faster and can become mushy. To mimic day-old texture, dry the cubes on a sheet pan in a 300°F oven for 8–12 minutes until slightly firm.
Q: How long can I refrigerate the assembled (but unbaked) casserole?
A: Cover and refrigerate up to 12–24 hours. After that, the bread may become overly saturated and break down. For best texture, bake within 24 hours.
Q: Is it safe to bake eggs that were soaked overnight?
A: Yes. The overnight soak is a standard make-ahead method. Bake the casserole until set; the center should reach about 160°F to ensure safe temperatures for egg-based custards.
Q: Can I double the recipe for a larger crowd?
A: You can double it, but use two pans rather than one oversized pan to ensure even baking. Adjust bake time as needed and check for doneness with an instant-read thermometer.
Q: What’s the best syrup to use?
A: Pure maple syrup enhances the cinnamon-vanilla flavors. For a richer glaze, warm the maple syrup slightly before drizzling so it flows and soaks in a bit.
