Steps

Before you start

Thaw puff pastry at room temperature for 20–30 minutes so it's pliable but still cold
Prep all filling ingredients before assembling—miso fillings can be sticky to work with
Have a small bowl of water ready for egg wash

1
Make miso caramel
- In a small saucepan over medium heat, melt the 2 tablespoons (28 g) of butter until foaming, about 1 minute.
- Add the 3 tablespoons (36 g) brown sugar and stir constantly until the mixture bubbles and turns deep amber, 3–4 minutes.
- Remove from heat and immediately whisk in the 1.5 tablespoons (27 g) white miso paste until fully incorporated—the mixture will smell sweet and savory at once.
- Stir in the ¼ teaspoon (1.2 ml) vanilla extract.
- Pour into a small bowl and let cool for 5 minutes until slightly thickened but still spreadable.
- This is your miso caramel.

Ready when: Mixture is deep amber and miso is fully incorporated, then cooled to room temperature
Tip: Whisk the miso in quickly off heat to prevent it from burning; the caramel should smell rich and slightly salty.
2
Prepare apple filling
- In a separate small bowl, combine the diced apples, ¼ teaspoon (1.3 cm) ground cinnamon, and ⅛ teaspoon (pinch) kosher salt.
- Toss gently to coat the apples evenly.
- This will release a light amount of juice and soften the apples slightly.

Ready when: Apples are evenly coated with spice
Tip: Use a sharp knife to dice the apples into consistent ½-inch pieces so they cook evenly inside the pie.
3
Cut and shape pastry
- Lightly flour a cutting mat or baking sheet.
- Unfold the thawed puff pastry sheet onto the mat.
- Using a sharp knife, cut the pastry into four 4.5-inch (11.4 cm) squares (you may have small scraps).
- Working with one square at a time, place it on the mat.
- Using a pastry brush or fork, brush a thin border of egg wash (about ½ inch / 1.3 cm wide) around all four edges of the square.

Ready when: Four pastry squares are cut and egg-washed borders are visible
Tip: Keep the pastry cold; if it begins to warm up and tear, slide it back into the freezer for 5 minutes.
4
Fill pies
- Spoon about 1 tablespoon (15 ml) of cooled miso caramel onto the center of each pastry square.
- Top with about ¼ cup (60 ml / 60 g) of the spiced diced apples, creating a small mound.
- Fold the pastry square in half diagonally to form a triangle, pressing down the edges firmly.
- Use a fork to crimp and seal the edges, creating a decorative pattern and ensuring a tight seal.

Ready when: All four pies are sealed and edges are crimped
Tip: Don't overfill; excess filling can leak out and cause the pastry to stick to the air fryer basket. The egg wash on the edges helps the seal stay tight.
5
Final egg wash
- Brush the top and sides of each sealed pie with the remaining egg wash, making sure to coat all visible pastry surfaces.
- This will help them brown evenly.

Ready when: Pastry is glossy and coated with egg wash

Air fry piesOven 380°F / 195°C
- Preheat your air fryer to 380°F (193°C) for 3 minutes.
- Arrange the four hand pies in the basket in a single layer, seam-side down, without overlapping (you may need to air fry in two batches if your basket is small).
- Air fry at 380°F (193°C) for 16 minutes, shaking the basket gently at the 8-minute mark to ensure even browning.
- The pastry should be deep golden brown and crispy.

Ready when: Pastry is deep golden brown on all sides and pastry sounds crispy when tapped
Tip: If your air fryer basket is smaller than 3.5 quarts, cook in two batches of two pies each to allow hot air to circulate freely.
7
Cool and finish
- Transfer the hand pies to a wire rack or clean plate.
- Let them cool for at least 5 minutes before serving so the filling sets slightly and the pastry can firm up.
- If desired, sprinkle a tiny pinch of fleur de sel over each warm pie just before serving.

Ready when: Pies are warm but cool enough to handle without burning your fingers
Tip: The fleur de sel enhances the savory miso note and balances the sweetness; it's optional but recommended.

Good to know

Tips

White miso adds a subtle umami and salty undertone that prevents the filling from tasting one-note sweet; it's worth seeking out at Asian markets or online.
The air fryer is ideal for these hand pies because it crisps the pastry without drying the filling—conventional ovens risk burning the edges before the inside warms.
Brush egg wash only on the pastry, not the apple mixture, or the apples will bake into the filling unevenly.
For a spiced caramel variation, add ⅛ teaspoon ground cardamom to the caramel after whisking in the miso.

Make ahead

You can assemble the hand pies up to 4 hours ahead: place them on a parchment-lined tray, cover loosely with plastic wrap, and refrigerate. Air fry directly from the fridge—add 2–3 minutes to the cooking time.

Storage & reheating

Room temperature (in an airtight container): up to 2 days. Refrigerator: up to 4 days. Freezer (uncooked, on a tray then in a freezer bag): up to 2 months—air fry directly from frozen at 380°F (193°C) for 20–22 minutes. Reheat in a 300°F (149°C) air fryer for 3–4 minutes or in a 325°F (163°C) oven for 5–7 minutes until warmed through and pastry re-crisps.

Substitutions

white (shiro) miso paste → red miso paste. Use the same amount. Red miso is deeper and earthier; the caramel will be slightly more savory.
Granny Smith apple → Honeycrisp or Gala apples. Sweeter varieties work well; reduce brown sugar by 1 tablespoon (12 g) if the apples are very sweet.
frozen puff pastry → homemade rough puff pastry. Make your own rough puff pastry if you prefer; the result will be slightly more rustic and flakier.
vanilla extract → almond extract. Use ⅛ teaspoon (0.6 ml) almond extract for a nuttier, more fragrant caramel.
