I want a breakfast that feels outrageously decadent but still belongs on a morning plate. This one delivers golden edges, a rich center, and the kind of payoff that makes scrolling impossible.

Jump to Recipe

I’m obsessed with this French toast casserole because croissants do the heavy lifting: buttery edges, custardy centers, and those flaky bits that get a little wild in the best way. I love how it tastes rich without trying too hard, like breakfast decided to show off after one sip of coffee.

And the maple syrup situation? Nonnegotiable.

It slides into every crack and makes the whole pan feel dangerously easy to keep picking at. But that’s exactly why I adore it.

Big bakery energy, minimal fuss vibes, and a sweet, soft, crisp bite that keeps pulling me back in again.

Ingredient Quantities

6 large croissants, preferably day-old, torn into 2 inch pieces (about 8 cups)

8 large eggs

2 cups whole milk

1 cup heavy cream or half and half

1/2 cup granulated sugar

1/4 cup packed light brown sugar

2 teaspoons pure vanilla extract

1 teaspoon ground cinnamon

1/4 teaspoon ground nutmeg

How to Make this

Print Recipe (No Advertisments)

1. Preheat oven to 350 F (175 C) and lightly butter a 9×13 inch baking dish.

2. Tear croissants into 2 inch pieces and place about two thirds of them in the prepared dish, reserving the rest.

3. In a large bowl whisk together eggs, whole milk, heavy cream or half and half, granulated sugar, brown sugar, vanilla, cinnamon, nutmeg, and salt until smooth.

4. Stir in the melted butter into the custard mixture.

5. Pour the custard evenly over the croissant pieces, pressing gently so the bread absorbs the liquid. Scatter the reserved croissant pieces on top.

6. Cover the dish with plastic wrap or foil and let sit at room temperature for 20 to 30 minutes to soak, or refrigerate overnight for a richer result.

7. Remove cover and bake uncovered for 40 to 50 minutes, or until the center is set and the top is golden brown.

8. Let the casserole rest for 10 minutes before serving.

9. Serve warm with pure maple syrup, dust with powdered sugar if desired, and garnish with fresh berries.

FAQ

Can I make this casserole ahead of time? Yes. Assemble the casserole, cover, and refrigerate for up to 24 hours. Bake straight from the fridge, adding a few extra minutes if needed until the center is set.

Can I use different bread instead of croissants? Yes. Brioche, challah, or thick country white bread work well. Croissants give the richest texture because of their layers and butter content.

Do I have to use whole milk and heavy cream? You can substitute with 2% milk and half and half if preferred. Using whole milk and cream yields a richer custard but lower fat options still produce good results.

How do I know when the casserole is done? It should be puffed and golden on top and a knife inserted in the center should come out mostly clean with just a little custard clinging. Internal temperature around 165 F is a good guideline.

Can I freeze the casserole? Yes. After baking and cooling, wrap tightly and freeze for up to 2 months. Thaw overnight in the fridge and reheat in a 350 F oven until warmed through.

How should I reheat leftovers? Reheat individual portions in a 325 F oven for 10 to 15 minutes, or microwave briefly on medium power until warm. A quick oven reheat preserves texture best.

French Toast Casserole With Croissants – Easy & Delicious! Recipe Substitutions and Variations

Croissants: Use brioche or challah torn into pieces for similar rich, tender texture; day old French bread or stale sliced sandwich bread work for a firmer, more custardy bake.
Whole milk and heavy cream or half and half: Substitute with equal parts evaporated milk and water for richness, or use all whole milk plus 2 extra eggs to mimic creaminess; for non dairy, use full fat canned coconut milk.
Granulated sugar and light brown sugar: Swap with coconut sugar or raw turbinado sugar 1:1 for a deeper, caramel note; use maple syrup or honey reduced by 25 percent of the liquid in the custard and taste for sweetness.
Unsalted butter: Use melted ghee or clarified butter for buttery flavor without water, or replace with neutral oil like canola at a 1:1 ratio for dairy free.

Pro Tips

1. Use croissants that are at least a day old and slightly stale so they soak up the custard without turning gummy. If yours are fresh, tear them and let them sit uncovered for a few hours to dry out a bit.

2. For the creamiest center, refrigerate the assembled dish overnight instead of only soaking at room temperature. Cold overnight soaking lets the custard penetrate fully and yields a richer texture when baked.

3. If the top is browning too quickly while the center is still jiggly, loosely tent with foil for the last 10 to 15 minutes of baking to prevent overbrowning while the center finishes cooking.

4. Boost flavor and texture with small add-ins: fold in 1/2 cup chopped toasted nuts, chocolate chips, or dried fruit with the custard, or sprinkle a tablespoon of demerara or turbinado sugar on top for a crunchy, caramelized finish.

5. Let it rest 8 to 10 minutes after baking so the custard firms up for cleaner slices. Serve warm with heated maple syrup or a quick berry compote to cut the richness.
