This Croissant French Toast Bake is sweet and ideal for brunch. Flaky croissants soak up a creamy custard and bake into a tender casserole with slightly crisp edges.
Perfect for holidays, weekend brunches, and easy make-ahead breakfasts. It pairs wonderfully with savory dishes like ham and cheese hashbrown casserole and makes a crowd-pleasing addition to any breakfast spread.

You can assemble this quickly and bake right away, or prepare it the night before for morning convenience. It’s flexible and forgiving, which makes it a go-to for busy mornings.
For a richer finish, top the bake with cream cheese frosting and candied walnuts β I often use the same candied walnuts I make for banana bread cinnamon rolls for an extra-special touch.
Why You’ll Love This Recipe
- Taste: Warm cinnamon and brown sugar with a hint of allspice, all wrapped in a creamy custard.
- Ease: Simple steps β cut the croissants, whisk the custard, assemble, and bake.
- Time: About 10 minutes to prep, 15 minutes to rest, and 45β50 minutes to bake.
π Ingredient Notes

- Croissants: Use fresh or slightly stale croissants, regular or gluten-free. Eight large croissants work well; you can also use 8β10 medium-sized ones.
- Brown sugar: Adds a rich, caramel-like sweetness that regular granulated sugar doesn’t provide.
- Whole milk: Keeps the custard creamy without being overly heavy; you can substitute plant-based milk with a tweak (see variations).
See the printable recipe card below for full ingredient amounts and nutrition details.
βοΈ Substitutions & Variations
- Plant-based milk: Soy or oat milk can replace whole milk; add an extra egg or 1 tablespoon cornstarch to help the custard set.
- Chocolate chips: Stir in white, dark, or semi-sweet chips for a dessert-like version.
- Cream cheese topping: A cream cheese glaze or whipped cream cheese makes a decadent finish.
π§βπ³ Instructions

- Step 1. Slice or tear the croissants into your preferred size β halves, quarters, or roughly 1-inch pieces all work.

- Step 2. Whisk the milk, brown sugar, eggs, vanilla, cinnamon, and allspice together until smooth and the eggs are broken up, about 1β2 minutes.

- Step 3. If pieces are large, dip each piece into the custard before arranging in a 9×13-inch casserole or baking dish so they absorb the mixture evenly.

- Step 4. Place croissant pieces in the pan and pour any remaining custard over the top. If pieces are small or cubed, simply combine everything in the dish and press down gently. Let rest at least 15 minutes or refrigerate overnight to allow soaking.
Tip
Large croissant pieces may not absorb the custard well unless you dip them first. Dipping ensures even soaking and a creamier interior.

- Step 5. Preheat the oven to 375Β°F and bake for 45β50 minutes until set and golden. Serve with fresh berries, a dusting of powdered sugar, and a drizzle of maple syrup.
Tip
If baking fruit into the casserole, choose blueberries, raspberries, or blackberries. Strawberries tend to dry out when baked and are best sliced fresh on top after baking.
π Troubleshooting
- Soggy bake: Likely underbaked or too much liquid. If baking from chilled, add 5β10 extra minutes.
- Dry bake: Too much croissant relative to custard, or overbaking. Adjust ratios and check earlier.
βοΈ Make Ahead, Store, Reheating Tips
To make an overnight croissant French toast casserole:
- Combine croissant pieces and custard in the baking dish and press down gently to help absorption.
- Cover and refrigerate for a few hours or overnight.
- Bake from chilled, adding a few extra minutes as needed.
Safety Tip: Avoid transferring a cold glass or ceramic dish straight into a hot oven. Let it sit while the oven preheats or place it in the oven while preheating.
Store: Refrigerate leftovers for up to 4β5 days.
Reheat: Warm in a 350Β°F oven covered with foil for 10β15 minutes, or microwave individual portions until heated through.
