Crispy Potato and Leek Puff Pastry Bites

These baked potato and leek puff pastry bites are irresistibly tasty. Creamy mashed potatoes blend with caramelized leeks, crisp turkey bacon and a touch of cheese, all wrapped in flaky, buttery puff pastry and baked until golden. They make a comforting appetizer or side that’s simple to prepare and easy to serve at parties, holidays or weeknight dinners.

Why this recipe works

• Flavor balance: Smooth mashed potato pairs with sweet, caramelized leeks and savory turkey bacon for a well-rounded bite. A small amount of cheese and green onion lifts the filling without overpowering it.
• Great for gatherings: These bites are finger-friendly, crowd-pleasing and kid-approved, making them ideal as an appetizer or a side, especially alongside steak or a green salad.
• Quick and flexible: Store-bought puff pastry and simple pantry ingredients make this recipe fast—ready in under an hour. The filling can be prepared ahead and chilled until you’re ready to assemble and bake.

How to make baked potato leek puff pastry bites

• Cook the turkey bacon until crisp. Bake or air-fry the slices, then chop them into small pieces. The crisp texture adds contrast to the creamy filling.
• Boil the potatoes until tender, then mash with a little butter so they remain slightly textured rather than completely smooth.
• Caramelize the leeks in a skillet with olive oil and add garlic toward the end so it doesn’t burn. The leeks should be soft and lightly browned.
• Combine everything in a bowl: mashed potatoes, caramelized leeks, chopped turkey bacon, shredded cheese, green onions, salt and pepper. Taste and adjust seasoning.
• Roll and cut the puff pastry: dust a board with flour, unroll the puff pastry and cut into about 10–12 squares depending on sheet size.
• Fill and seal: place about 1 heaping tablespoon of filling in the center of each square. Lightly wet the pastry corners with water if needed, then pinch opposite corners together to form a sealed pocket.
• Brush with egg wash and bake: transfer bites to a parchment-lined baking sheet, brush with beaten egg and bake at 400°F (204°C) until golden, about 21–24 minutes. Let cool slightly before serving.

Tips and FAQs

• Work with cold puff pastry: keep the dough refrigerated until you’re ready to cut it so it’s easier to handle and less likely to stick.
• Avoid overfilling: about one heaping tablespoon per square is ideal. Overfilling can cause seams to open while baking, although the filling will still be tasty if that happens.
• Vegetarian option: omit the turkey bacon or swap in a plant-based bacon alternative or extra mushrooms for a vegetarian version.
• Reheating and storage: store leftovers in an airtight container in the fridge for up to 4 days. Reheat briefly in the oven or air fryer (about 10 minutes at 375°F) to crisp the pastry again.
• Egg wash alternative: brush with milk for a softer sheen if you prefer not to use egg wash.

Equipment

• Large baking sheet
• Parchment paper
• Medium pot (to cook potatoes)
• Colander or slotted spoon (to drain potatoes)
• Potato masher
• Medium bowl
• Small skillet (to cook leeks)
• Cutting board
• Pizza cutter or knife
• Tablespoon measuring spoon
• Small bowl (for egg wash)
• Basting brush

Ingredients

• 2 slices turkey bacon (about 2 tablespoons, chopped)
• 2 cups potatoes, peeled and cubed
• 1/2 tablespoon olive oil
• 3/4 cup leeks, finely chopped
• 1 garlic clove, minced
• 1/2 tablespoon butter (salted if possible)
• 1/2 teaspoon salt, more or less to taste
• Pinch black pepper, to taste
• 1/4 cup shredded mozzarella or gruyère
• 1 tablespoon green onions, finely chopped
• 1 egg, beaten with 1 teaspoon water (for egg wash)
• 1 sheet puff pastry (about 375 g)
• All-purpose flour, as needed for dusting

Instructions

1. Preheat the oven to 400°F (204°C).
2. Cook turkey bacon on a parchment-lined baking sheet until crisp, about 7–9 minutes. Remove and chop finely. Keep the oven on.
3. Place peeled, cubed potatoes in a medium pot and cover with water. Bring to a boil, then reduce heat and simmer until potatoes are fork-tender, about 10 minutes. Drain.
4. While potatoes cook, heat the olive oil in a small skillet over medium heat. Add the chopped leeks and cook 8–10 minutes, stirring often, until soft and slightly caramelized. Add the minced garlic halfway through cooking.
5. Return drained potatoes to a medium bowl and mash with butter until just slightly chunky. Add the cooked leeks, chopped turkey bacon, shredded cheese, green onions, salt and pepper. Stir to combine and taste to adjust seasoning. Set the filling aside.
6. Lightly flour a cutting board, unroll the puff pastry and cut into 10–12 squares (depending on pastry size). Each square will make one bite-sized pocket.
7. Place about one heaping tablespoon of filling in the center of each square. If needed, wet the pastry corners with a fingertip dipped in water and pinch opposite corners together diagonally, then pinch the remaining corners to seal.
8. Line a baking sheet with parchment paper. Beat the egg with 1 teaspoon water and brush the tops of each filled pastry. Bake 21–24 minutes or until golden brown. Allow the bites to cool for a few minutes before serving.

Notes

• Baking time: ovens vary; check for a golden top between 21 and 24 minutes.
