For the Custard

  • Whole Milk – Provides creaminess to the custard; substitute with almond milk for a dairy-free version.
  • Heavy Cream – Adds richness; use half-and-half for a lighter option.
  • Large Eggs – Binds the casserole together for a perfect custard-like texture; flax eggs can be a vegan alternative.
  • Granulated Sugar – Sweetens the dish; brown sugar can add extra depth of flavor.
  • Vanilla Extract – Enhances overall flavor; opt for pure extract for the best taste.
  • Banana Extract – Intensifies the banana flavor; omit if unavailable, and increase the number of fresh bananas.
  • Salt – Balances sweetness; it’s essential for flavor enhancement.

For the Casserole

  • Ripe Banana – Provides natural sweetness and texture; ensure they are ripe but not overripe.

Step‑by‑Step Instructions for Banana Croissant Casserole

Step 1: Preheat the Oven and Prepare the Baking Dish
Begin by preheating your oven to 350°F (175°C). While the oven heats, take an 8 x 8-inch baking dish and generously coat it with cooking spray. This ensures easy removal of the baked Banana Croissant Casserole. Set the dish aside as you move on to preparing the custard mixture.

Step 2: Whisk the Custard Ingredients
In a large mixing bowl, whisk together 2 cups of whole milk, 1 cup of heavy cream, 4 large eggs, ½ cup of granulated sugar, 1 teaspoon of vanilla extract, 1 teaspoon of banana extract, and a pinch of salt. Mix thoroughly until all ingredients are fully combined and the sugar is dissolved. This creamy custard will beautifully envelop the croissants and bananas.

Step 3: Combine Croissants with Custard
Add the chopped day-old croissants to the custard mixture, ensuring each piece is thoroughly coated. Gently stir the croissant pieces into the mixture and allow it to rest for 25-30 minutes. This allows the croissants to absorb the custard, becoming tender and flavorful. Stir gently halfway through to ensure even soaking.

Step 4: Incorporate Bananas and Transfer to Baking Dish
After the croissants have soaked, fold in sliced ripe bananas, incorporating them evenly into the mixture. Carefully pour the entire mixture into the prepared baking dish, spreading it out to ensure an even layer. The combination of bread and banana is the heart of your delicious Banana Croissant Casserole.

Step 5: Bake to Perfection
Place the baking dish in the preheated oven and bake for 45-50 minutes. Keep an eye on your casserole; it’s done when the custard is set and the top is golden brown. The baking time may vary slightly based on your oven, so check for a fluffy texture and lightly crispy exterior to know it’s perfect.

Step 6: Cool Before Serving
Once baked, remove the Banana Croissant Casserole from the oven and let it cool for 10 minutes before serving. This resting time allows it to firm up slightly, making it easier to cut and serve. The tantalizing aroma will fill your kitchen, inviting everyone to gather around the table to enjoy your delightful creation.

Expert Tips for Banana Croissant Casserole

  • Use Stale Croissants: Ensure your croissants are day-old or stale; fresh ones can become too mushy when soaked in the custard.

  • Let it Rest: Allow the casserole to cool for 10 minutes after baking; this helps it set properly, making serving easier and more attractive.

  • Check for Doneness: Monitor the baking closely, especially after 40 minutes; overbaking can cause a dry texture, while underbaking leaves the custard too runny.

  • Customize with Extras: Feel free to add spices like cinnamon or nutmeg; these enhancements can elevate the flavor profile of your Banana Croissant Casserole.

  • Storage Made Easy: Leftovers can be stored in an airtight container for up to 3 days; just reheat in the oven for a delightful breakfast encore.
