“I made this for Easter morning and everyone asked for seconds — crisp on top, custardy inside, and ridiculously simple.”
That kind of praise is common because the recipe balances a soft custard interior with a brown-sugar, cinnamon-topped crust.
The cooking process explained
At a glance: cube bread, whisk a vanilla-cinnamon egg custard, pour it over the bread and let it soak for at least 2 hours (overnight is best). Top with a melted butter + brown sugar crumble and bake at 375°F until set and golden. Cool briefly, then dust with powdered sugar or drizzle with warm maple syrup and serve. The overnight soak lets the custard fully permeate the bread so every bite is tender and flavorful.
What you’ll need
- 1 loaf bread (brioche or French recommended; day-old is ideal)
- 8 large eggs
- 1 1/2 cups milk (whole milk gives best richness; use 2% or a non-dairy milk if needed)
- 2 tsp ground cinnamon
- 1 tbsp vanilla extract
- 1/4 cup granulated sugar
- 1/2 tbsp orange juice (optional — brightens the flavor)
- 4 tbsp unsalted butter, melted (for topping)
- 2 tbsp light brown sugar (for topping)
- 1 tbsp granulated sugar (for topping)
- 1 tsp ground cinnamon (for topping)
- 1/8 tsp salt (for topping)
- Maple syrup and powdered sugar, for serving
Substitutions and notes: swap challah for brioche, use coconut milk for dairy-free (the texture will be slightly different), and replace granulated sugar with coconut sugar or maple syrup (reduce other liquids slightly).
Step-by-step instructions
- Spray a 9×13 baking dish liberally with non-stick cooking spray.
- Cut or tear the loaf into 1–2 inch cubes. Place the bread in a large bowl and set aside.
- In a separate large bowl, whisk together the eggs, milk, 1/4 cup granulated sugar, 2 tsp cinnamon, vanilla, and optional orange juice until smooth.
- Pour the egg mixture over the bread. Gently fold with a spatula to coat evenly. Make sure all pieces get some custard.
- Transfer the coated bread into the prepared baking dish. Cover tightly and refrigerate for at least 2 hours or overnight for best results.
- When ready to bake, preheat the oven to 375°F. Remove the casserole from the fridge while the oven heats.
- Make the brown sugar cinnamon topping: combine melted butter, 2 tbsp light brown sugar, 1 tbsp granulated sugar, 1 tsp cinnamon, and 1/8 tsp salt. Whisk until smooth.
- Spoon the topping evenly over the surface of the soaked bread. Use the back of a spoon to distribute if needed.
- Bake for 35–45 minutes, until the top is light golden and the center is set. A toothpick inserted in the center should come out mostly clean; internal temperature should reach about 160–165°F for full food-safety confidence.
- Remove from oven and cool on a wire rack for 10 minutes. Dust with powdered sugar or drizzle with warm maple syrup, then slice and serve.
Best ways to enjoy it
Serve warm. Classic options include:
- A generous drizzle of good-quality maple syrup.
- Fresh berries or a spoonful of berry compote to cut the richness.
- A side of thick-cut bacon or sausage for contrast.
- A dollop of whipped cream or mascarpone for true indulgence.

Storage and reheating tips
- Refrigerate leftovers in an airtight container for up to 3–4 days.
- To reheat a single serving: microwave for 30–60 seconds (cover loosely to avoid splatter). The microwave makes the texture softer.
- For best texture, reheat in a 350°F oven for 8–12 minutes until warmed through and the top reheats to crispness.
- Freezing: cut into portions, wrap tightly in plastic and foil, and freeze for up to 2 months. Reheat from frozen in a 350°F oven (cover with foil until warm, then uncover to crisp).
- Food safety: cool to room temperature no longer than 2 hours before refrigerating.
Helpful cooking tips
- Use day-old bread for structure. Fresh bread can turn overly mushy unless you tear it into larger pieces and reduce soak time.
- Cube or tear bread into uniform pieces so custard penetrates evenly.
- Don’t skimp on the topping — the brown sugar-butter layer creates the best crunch.
- If you prefer a softer top, add the topping halfway through baking rather than before.
- Test doneness with a toothpick or an instant-read thermometer; custard should be set and slightly springy.
- For a deeper flavor, toast the bread cubes lightly before soaking.
Creative twists
- Apple-cinnamon: fold in 1–2 cups diced apples tossed in cinnamon before baking.
- Berry-streusel: add a layer of fresh berries and swap the topping for a streusel made with oats.
- Savory: omit sugars and cinnamon, add grated Gruyère and herbs, and serve as a strata with ham or spinach.
- Gluten-free: use gluten-free brioche-style bread and check manufacturer’s instructions for freezing and reheating.
- Boozy brunch: splash 1–2 tbsp bourbon or rum into the custard for a grown-up touch.
Common questions
Q: Do I have to refrigerate the casserole before baking?
A: You don’t have to, but refrigerating for at least 2 hours — or overnight — gives the custard time to soak into the bread, producing a creamier interior.
Q: Can I use a different bread than brioche?
A: Yes. Challah, French bread, or any sturdy loaf works well. Use day-old bread when possible; it absorbs custard better and holds structure.
Q: How can I tell when the casserole is done?
A: The top should be light golden and slightly crisp. A toothpick in the center should come out mostly clean. For safety, the center should reach about 160–165°F.
Q: Can I assemble the casserole ahead and freeze it unbaked?
A: Yes. Assemble and cover tightly, then freeze for up to 2 months. Thaw in the refrigerator overnight before baking, then bake as directed; you may need a few extra minutes.
Q: What does the orange juice do?
A: The small amount of orange juice brightens the custard flavor and balances sweetness. It’s optional but recommended for subtle citrus notes.
Q: How many people does a 9×13 pan serve?
A: Generally 8–10 servings, depending on portion size and sides.
