Whenever we've got leftover croissants and a banana that's seen better days, this baked banana croissant breakfast is our go to. It turns those bakery scraps into a creamy, dreamy morning treat that always feels like a little celebration but takes almost no time to throw together.

The first time I made it for Croissant Day, the banana and buttery smell filled the house and everyone just had to peek their heads in to see what was baking.

Tasty Ingredients

  • Maple syrup: drizzle some over the dish after baking for a sweet finish only go for the real stuff if you can
  • Day old croissants: the flakier the better they soak up the mixture and get crispy tops while staying soft inside
  • Ripe banana: pick a banana with brown spots but not all mushy gives the dish a mellow banana flavor and creamy bite
  • Salt: just a pinch does the trick to boost the flavors
  • Banana extract: kicks up the banana flavor use it if you want to really taste the fruit
  • Vanilla extract: makes everything warm and cozy stick to pure if you can
  • Granulated sugar: sweetens the whole thing I like using organic for a hint of caramel taste
  • Large eggs: holds it together while keeping the custard soft
  • Heavy cream: serious richness and turns it into bread pudding territory
  • Whole milk: makes everything smooth go for whole milk for the best texture

Simple Step-by-Step Directions

Rest and Serve:
Give it ten minutes to cool down before slicing in. This helps the custard set and makes it way easier to serve. Pour on some maple syrup before you dig in.
Bake It:
Slide the dish into the oven right in the middle at 350 degrees F. Bake for about 45-50 minutes. It's done when you poke the center and it doesn't jiggle. The top should look browned.
Add Bananas:
Carefully tip the croissant mixture into your oiled dish and scatter banana slices all over. Gently push the fruit in so every piece gets plenty.
Soak the Croissants:
Chop or tear your croissants, toss them into the bowl, and fold until coated all over. Let it all soak about half an hour, stirring once. This makes sure every bite gets fluffy from the creamy custard.
Make the Custard:
Grab a large bowl and whisk up 1 cup milk, 1 cup cream, 2 eggs, 1 cup sugar, 1 tbsp vanilla, 1 tbsp banana extract, and 1/4 tsp salt. Whisk until it looks mixed and smooth with sugar melted in.
Prep the Pan:
Spray an 8 inch square baking dish with nonstick spray so nothing sticks. Keep it close—you’ll need it in just a bit.

Honestly, I love how the croissants puff up while baking and get toasty on top. When the banana caramelizes, my kids go right for those crispy golden corners every time.

Storing Made Easy

Toss leftovers in the fridge covered for three days tops. The inside stays soft and the croissants keep some bite. Reheat slices in the microwave or a 300 degree oven until nice and warm.

Swaps and Substitutes

No croissants? Brioche or challah totally work. Almond extract adds a nutty vibe. Skip banana extract? Just use a second banana for double the fruity flavor.

How to Serve

Warm it up and pour on pure maple syrup. Toss on extra banana slices for good measure. Goes great with berries, whipped cream, coffee, or a big mug of chai.

Origins and Traditions

Think of this as a mashup between French toast and bread pudding. Comfort food at its best. The croissants add that French café feel while bananas and creamy custard keep it super classic American breakfast style.

Frequently Asked Questions

→ Is it okay to make this dish a day early?

Definitely! Just put it together the night before, cover, and pop in the fridge. Bake it right before you want to eat.

→ Which type of croissants should I use?

Ones that are a day old are best because they'll soak up all that creamy stuff and not get mushy.

→ Can I swap out banana extract?

If you don't have banana extract, use a little mashed banana or an extra dash of vanilla to boost the flavor.

Difficulty: Easy

Cuisine: French-style

Yield: 6 Servings (1 baking dish)

Dietary: Vegetarian

Ingredients

→ Custard Base

01 0.25 teaspoon salt
02 1 tablespoon banana extract
03 1 tablespoon vanilla extract
04 200 g granulated sugar
05 2 large eggs
06 240 ml heavy cream
07 240 ml whole milk

→ Assembly

08 6 croissants, stale and cut into big chunks
09 1 banana, ripe and cut into slices

→ For Serving

10 Maple syrup, use as much as you like

Instructions

Step 01

Cut out pieces while it’s nice and warm. Pour on some maple syrup if you want.

Step 02

Slide it into the oven without a lid and bake for 45 to 50 minutes. When the top looks golden and the custard isn’t runny, take it out. Let it stand about 10 minutes before anyone digs in.

Step 03

Dump the soaked croissant mix into your greased baking dish. Push banana slices down throughout so they’re spread around.

Step 04

Toss the croissant bits right into the custard. Stir till everything’s coated. Leave it sitting for 30 minutes or so, making sure to mix it halfway so it soaks up evenly.

Step 05

Grab a big bowl and whisk together milk, cream, eggs, sugar, both extracts, and salt. Keep mixing till it’s smooth.

Step 06

Heat your oven to 175°C. Coat your 20 x 20 cm baking dish with oil or spray so nothing sticks, then set aside.

Notes

  1. Letting your croissants sit overnight actually helps them soak up custard way better and not fall apart.
  2. Don’t cut it up right away. Resting after baking makes it easier to slice and the taste gets even better.
