Essential Ingredients
Here’s what you’ll need to make this delicious dish:
- Day-Old Croissants: Use stale croissants for the best texture; they’ll soak up the custard beautifully without becoming mushy.
- Sweet Potatoes: Choose firm sweet potatoes with smooth skin for optimal flavor and sweetness.
- Eggs: Fresh large eggs are essential; they help create that rich custard consistency.
- Milk or Cream: Whole milk adds richness, but cream can elevate it to decadent heights.
- Cinnamon: Ground cinnamon enhances the warmth and sweetness of the dish; don’t skip it!
- Brown Sugar: Use light or dark brown sugar for added depth; it caramelizes beautifully while baking.
- Vanilla Extract: Pure vanilla extract makes all the difference in flavor; steer clear of imitation varieties.

How to Make Sweet Potato Croissant Casserole
Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish with butter or non-stick spray for easy cleanup later.
Prepare the Sweet Potatoes: Peel and cube about two medium sweet potatoes. Boil them in salted water until fork-tender—around 15 minutes should do.
Mash and Mix: Drain the sweet potatoes and mash them until smooth. Stir in brown sugar, cinnamon, vanilla extract, and a pinch of salt until well combined.
Create the Custard: In another bowl, whisk together eggs and milk (or cream) until frothy. Add in more sugar and whisk until dissolved; it should be creamy and smooth.
Assemble Your Casserole: Tear croissants into bite-sized pieces and layer half in your greased dish. Spread half of the sweet potato mixture over them then pour half of the egg mixture on top.
Add More Layers: Repeat with remaining croissant pieces followed by sweet potato mix and finish off with custard pour-over. Press lightly down so everything melds together nicely.
Bake to Perfection: Bake uncovered for about 45-50 minutes or until golden brown on top and set in the middle. Let cool slightly before serving; this allows flavors to meld beautifully!
This Sweet Potato Croissant Casserole is not just food; it’s an experience! The crispy edges contrast perfectly with creamy layers, making each bite a celebration of flavors that scream comfort food at its finest. Whether you’re serving it at brunch or enjoying it solo after dinner while binge-watching your favorite show (no judgment here), this dish promises satisfaction all around!
