These South Indian egg puffs are made with flaky puff pastry, a spicy caramelized onion masala, and hard-boiled eggs. They are baked until golden and crisp, making an easy bakery-style snack to serve with chai and ketchup.
Hard-boil the eggs, peel them, and slice each lengthwise into halves. Set aside to cool completely.
Heat the oil in a frying pan over medium heat. Add the sliced onions and cook 8 to 10 minutes, stirring occasionally, until golden and collapsed to about a third of their volume.
Add the ginger, garlic, and curry leaves. Cook 1 to 2 minutes until the raw smell is gone.
Add the turmeric, chili powder, garam masala, salt, and ketchup. Stir to coat and cook 3 to 4 minutes, until the mixture pulls away from the pan and no liquid pools when you drag a spoon through it.
Turn off the heat and let the filling cool completely.
Assemble and bake
Preheat the oven to 430℉ for at least 10 to 15 minutes.
Cut each puff pastry sheet into 4 equal squares, 12 total. Work with one sheet at a time and keep the rest refrigerated.
Brush water along all four edges of a square. Place 1 tablespoon of cooled onion filling in the center. Place half an egg on top, yolk side down.
Bring the four corners together over the egg and press to seal completely. Repeat with the remaining squares.
Arrange on a parchment-lined baking sheet with space between each puff. Brush the exposed pastry evenly with beaten egg white.
Bake 15 to 20 minutes, until deep golden with visibly separated layers. Cool a few minutes before serving.
Notes
The filling must be dry. Drag a spoon through the pan: if liquid seeps back into the channel, keep cooking.
Both the masala and the eggs must be fully cooled before they go into the pastry. Warm filling steams the layers.
Keep the pastry cold. Take one sheet out at a time; the rest in the refrigerator.
Yolk side down leaves the smooth white facing up so the corners fold cleanly.
Preheat fully. Puff pastry needs immediate high heat to separate.
Onion masala keeps 5 days refrigerated. Baked puffs keep 3 days refrigerated or 3 months frozen. Reheat in a 350F oven or air fryer, not the microwave.
