I nailed Easy Blueberry Turnovers that come out as glossy, jammy pockets with flaky layers and absolutely no soggy bottoms.

Jump to Recipe

I am obsessed with these blueberry pastry turnovers. I love the way puff pastry shatters into thin, flaky sheets around warm blueberries.

And the fruit pops with bright lemon zest, sweet and tart and utterly addictive. I grab them for lazy mornings, because they’re the kind of Blueberry Breakfast Pastry that actually makes me get out of bed.

But they work any time I need a quick, loud snack. Easy Blueberry Turnovers that look fancy but don’t act like they are.

I keep finding excuses to bake more. Worth every flaky, sticky bite, I swear and I am shameless really.

Ingredient Quantities

1 sheet frozen puff pastry, thawed (about 8 ounces)

2 cups fresh or frozen blueberries, drained if frozen

1/3 cup granulated sugar

2 tablespoons cornstarch

1 tablespoon fresh lemon juice

1 teaspoon lemon zest

1/2 teaspoon vanilla extract

Pinch of salt

1 large egg, beaten for egg wash

1 to 2 tablespoons coarse sugar or turbinado for sprinkling (optional)

1 cup powdered sugar and 1 to 2 tablespoons milk for glaze (optional)

How to Make this

Print Recipe (No Advertisments)

1. Preheat oven to 400°F (200°C) and line a baking sheet with parchment paper; keep the puff pastry chilled until you’re ready to roll so it stays flaky.

2. In a bowl combine blueberries, granulated sugar, cornstarch, lemon juice, lemon zest, vanilla extract and a pinch of salt; if your blueberries were frozen make sure they are mostly thawed and drained so filling isn’t watery.

3. If using, dot the filling with the small pieces of unsalted butter; this gives a richer sauce and helps the filling gloss up when baked.

4. On a lightly floured surface gently unfold and roll the thawed puff pastry into a roughly 10 x 10 inch square, then cut into four equal squares.

5. Spoon about 2 to 3 tablespoons of the blueberry mixture into the center of each square, leaving a 1/2 inch border; don’t overfill or they will leak.

6. Lightly brush the edges with the beaten egg or a little water, fold each square into a triangle, press the edges together and crimp with a fork to seal; cut a couple small slits or poke holes in the top for steam to escape.

7. Place turnovers on the prepared sheet, brush the tops with more beaten egg, and if using sprinkle with coarse or turbinado sugar for extra crunch and color.

8. For cleaner puff and less leakage chill the assembled turnovers in the fridge for 10 to 15 minutes before baking; then bake 18 to 22 minutes until puffed and golden brown.

9. Remove from oven and cool on a rack for at least 10 minutes so the filling sets; if you want a glaze whisk powdered sugar with 1 to 2 tablespoons milk until smooth and drizzle over warm but not piping hot turnovers.

10. Serve warm or at room temperature; reheat briefly in a toaster oven to refresh the crispness.

Equipment Needed

1. Baking sheet lined with parchment paper
2. Medium mixing bowl (for the blueberry filling)
3. Measuring cups and spoons
4. Rolling pin and lightly floured work surface
5. Sharp knife and small cutting board (for butter and vents)
6. Pastry brush (for egg wash)
7. Fork and spatula or spoon (to seal edges and fill turnovers)
8. Wire cooling rack and a small tray or plate for chilling in the fridge

FAQ

Q: Can I use frozen blueberries instead of fresh?

A: Yes, you can. Thaw and drain them well first so the filling is not too watery. Toss them with the sugar and cornstarch while still slightly cold to help them hold together better.

Q: How do I stop the pastry from getting soggy on the bottom?

A: Blind bake for 3 minutes at the recipe temp or brush a thin layer of beaten egg on the pastry base before adding filling. Also don't overfill and make sure the berries are well coated with cornstarch.

Q: My filling seeps out while baking, what went wrong?

A: Usually it's too much filling or not enough thickener. Use the listed cornstarch, chill the filled turnovers in the fridge for 10 minutes before baking, and press edges firmly to seal with a fork. Egg wash the edges to help them stick.

Q: Can I make these ahead of time and freeze them?

A: Yes. Assemble but don't egg wash or sprinkle sugar. Freeze on a tray until solid, then bag. Bake from frozen, add a couple extra minutes to the baking time and brush with egg wash right before they go in the oven.

Q: Any tips for a shiny, nice looking finish?

A: Brush with beaten egg before baking for a golden sheen. Sprinkle coarse sugar for crunch after egg wash and before baking. For extra gloss, brush with a simple powdered sugar glaze after cooling a bit.

Q: Can I swap the lemon for something else?

A: You can use orange zest and a teaspoon of orange juice for a different flavor, or omit citrus but you might want a splash of apple cider vinegar or a tiny bit more vanilla to brighten the filling.

Blueberry Pastry Turnovers Recipe Substitutions and Variations

Puff pastry: swap with store bought crescent roll dough for a softer, slightly sweeter turnover, or use refrigerated pie crust for a flakier, denser result.
Blueberries: try raspberries or blackberries for similar tartness, or diced apples (toss with a little extra lemon and sugar) for a fall variation.
Cornstarch: use arrowroot in a 1:1 ratio for a clear, glossy filling, or use all purpose flour at about double the amount (results a bit less clear and slightly thicker).
Egg wash: brush with milk, cream, or melted butter instead for browning if you want to skip eggs; milk gives a softer sheen, butter gives richer color and flavor.

Pro Tips

1. Keep that puff pastry ice cold until the last second. Chill the sheet, work fast and if it softens too much pop it back in the fridge for 10 minutes. If it gets warm you’ll lose the layers and they’ll flatten out in the oven.

2. Don’t let wet blueberries ruin it. If you used frozen berries squeeze or drain out as much juice as you can, or toss them with a tablespoon of extra cornstarch and let them sit 5 minutes so they absorb excess liquid. Overfilling also makes leaks, so stick to the 2 to 3 tbsp guideline.

3. Seal and vent right. Press edges firmly with a fork and brush the seam with egg wash or a little water so it stays shut. Cut 2 small slits on top for steam, and if you have time chill the assembled turnovers 10 to 15 minutes before baking to reduce blowouts.

4. Little touches matter. Dot the filling with tiny bits of cold butter for a glossy sauce, sprinkle turbinado sugar for crunch, and wait until the turnovers are warm not piping hot to drizzle the glaze so it doesn’t just melt away. Reheat leftovers briefly in a toaster oven to restore crispness.
