How to Make Rhubarb Puff-Tart Pockets (Step-by-Step Instructions)

Step 1: Prep the Puff Pastry

Thaw 1 sheet (about 8–10 ounces) of store-bought puff pastry in the fridge overnight or at room temperature for 40 minutes, per package instructions. Keep it cold but pliable. Preheat your oven to 400°F and line a baking sheet with parchment paper or a silicone baking mat. Pro tip: Cold puff pastry puffs up best—don’t let it get too warm while prepping.

Step 2: Make the Rhubarb Filling

In a medium saucepan over medium heat, combine 2 cups chopped fresh rhubarb (½-inch pieces), ½ cup granulated sugar, 1 tablespoon cornstarch, 1 tablespoon fresh lemon juice, 1 teaspoon vanilla extract, and a pinch of salt. Cook, stirring occasionally, for 5–7 minutes until the rhubarb softens and the mixture thickens into a jammy consistency. If using, add ½ cup chopped strawberries or a pinch of cinnamon in the last 2 minutes. Remove from heat and let cool completely, about 20 minutes. Note: Cooling the filling prevents soggy pastry, so don’t skip this step.

Step 3: Cut the Pastry

Unfold the thawed puff pastry on a lightly floured surface and roll gently to smooth creases, keeping it about 10×10 inches. Cut into 6 equal squares (about 3×3 inches each) using a sharp knife or pizza cutter. Heads-up: Work quickly to keep the pastry cold—pop it in the fridge for 10 minutes if it starts softening.

Step 4: Assemble the Pockets

Place 1–1 ½ tablespoons of cooled rhubarb filling in the center of each pastry square, leaving a ½-inch border. Fold each square diagonally to form a triangle, pressing the edges firmly to seal. Use a fork to crimp the edges for a tight seal and a decorative look. Transfer pockets to the prepared baking sheet, spacing 2 inches apart. Tip: Don’t overfill—too much filling can leak and make the pastry soggy.

Step 5: Add Egg Wash

In a small bowl, whisk 1 large egg with 1 teaspoon water to make an egg wash. Brush lightly over the tops of the pockets for a shiny, golden finish. Cut a small slit in the top of each pocket to let steam escape. Note: The egg wash is key for that bakery-style look, but don’t drench the pastry—it can weigh it down.

Step 6: Bake

Bake for 18–22 minutes, until the pockets are puffed, golden brown, and crisp. Rotate the baking sheet halfway through for even browning. Let cool on the baking sheet for 5 minutes, then transfer to a wire rack to cool slightly or fully, depending on how you’re serving. Pro tip: Check at 18 minutes—overbaking can dry out the filling.

Step 7: Serve

Dust the warm or cooled pockets with powdered sugar using a fine mesh sieve for a pretty finish. For a glaze, mix ½ cup powdered sugar with 1–2 teaspoons lemon juice and drizzle over the pockets. Serve warm with vanilla ice cream or at room temperature as a grab-and-go treat. Tip: Warm pockets are gooey and delicious, but they hold their shape better when cooled slightly.

Helpful Tips

• Meal prep it: Make the rhubarb filling up to 2 days ahead and store in the fridge. Assemble pockets up to 4 hours ahead, refrigerate, and bake fresh. Or freeze unbaked pockets for later (see below).
• Storage: Store cooled pockets in an airtight container at room temp for up to 2 days or in the fridge for up to 4 days. Freeze baked or unbaked pockets, wrapped tightly, for up to 2 months—bake from frozen, adding 3–5 minutes.
• Reheating: Reheat in a 350°F oven for 5–7 minutes to restore crispness. Microwave for 15–20 seconds, but the pastry may soften.
• Perfect pairings: Pair with vanilla ice cream, whipped cream, or a hot cup of chamomile tea. Serve with fresh berries or yogurt for a brunch spread.
• Creative twists:
• Add ½ cup chopped strawberries or raspberries to the filling for a mixed berry vibe.
• Stir a pinch of cardamom or ginger into the filling for a spiced twist.
• Brush with a honey glaze instead of powdered sugar for extra sweetness.
• Add a tablespoon of cream cheese to the filling for a creamy tang.
• Sprinkle coarse sugar over the egg wash for a sparkly, crunchy top.
• Avoid soggy pastry: Cool the filling completely before assembling, and don’t overfill. Seal edges tightly and bake immediately to keep the pastry flaky.

Frequently Asked Questions (FAQs)

Can I make these ahead of time?
Yes! Prep the filling up to 2 days ahead and store in the fridge. Assemble pockets up to 4 hours ahead, refrigerate, and bake fresh. Or freeze unbaked pockets and bake from frozen, adding a few minutes.

Can I freeze puff-tart pockets?
Absolutely! Freeze unbaked pockets on a baking sheet, then transfer to a freezer bag for up to 2 months. Bake from frozen at 400°F for 22–25 minutes. Baked pockets freeze well too—thaw and reheat in the oven.

What if I don’t have fresh rhubarb?
Use frozen rhubarb, thawed and patted dry, but fresh is best for texture and flavor. Reduce to 1 ¾ cups if frozen, as it releases more liquid. You can also mix with strawberries to stretch it.

Can I make this gluten-free or vegan?
For gluten-free, use gluten-free puff pastry. For vegan, use vegan puff pastry, swap egg wash for a mix of 1 tablespoon plant milk and 1 teaspoon maple syrup, and use vegan butter in the filling if desired.

Why did my pockets leak?
Leaking can happen from overfilling, warm filling, or weak seals. Use 1–1 ½ tablespoons filling, cool it completely, and crimp edges firmly with a fork. A steam slit also helps prevent bursting.
