Flaky Sourdough Turnovers with Jam

Nostalgic for Hand Pies? These Ones Actually Deliver.

As is often the case with nostalgia, the memory of Pop-Tarts is way better than the reality. These days, the pastry is bland, the filling is mystery goo, and the icing looks like it was applied by a sneeze.

Still, the craving lingers. So, in true Type-A-baking-freak fashion, I set out to reimagine the Pop-Tart of my dreams. Enter: sourdough turnovers. Think tender, flaky, flavorful crust (thank you, sourdough discard) wrapped around a filling that’s actually worth eating—jam, marmalade, custard…whatever you’re into.

With layers this good, icing is optional. Personally? I let the pastry and filling shine.

The Magic of Sourdough Pastry

Sourdough discard isn’t just for pancakes and crackers—it adds a subtle tang and a surprising depth of flavor to pastry. Bonus: you get to feel smug about using up every drop of your starter (because tossing it just feels wrong).

Choose Your Own Adventure: Fill Freely

Jam is the classic choice here—strawberry, raspberry, and apricot all shine—but these turnovers are basically a choose-your-own-dessert adventure. Think lemon curd, chocolate hazelnut spread, or even a swirl of cream cheese with jam. Just keep it to about a tablespoon per turnover so you don’t end up with an oven crime scene.

Tip and Tricks for Turnover Triumph

Where’s the Rectangle?

Sure, Pop-Tarts are rectangles—but triangles might be the smarter move. They’re easier to assemble, no need to fuss with perfectly matched pieces of dough. Just cut squares and fold them into neat little jam pockets. Still craving the rectangle look? Fill and fold straight across instead of diagonally for a McD’s-style hand pie.

The Chill Factor

Pastry loves the cold. If your dough starts feeling floppy, pop it in the fridge for a quick reset. That’s the difference between flaky, airy layers and sad, dense pastry. Hot kitchen? Expect more chill breaks.

To Ice or Not to Ice?

I usually skip the icing—the jam is sweet enough, and I like letting the buttery crust have its moment. But if nostalgia calls, a quick glaze and some sprinkles (rainbow, freeze-dried fruit dust, or even flaky salt) will give you full Pop-Tart vibes.

Storage & Reheating Tips

These turnovers stay flaky for about two days in an airtight container. After that, a quick 2-3 minutes in the toaster oven or air fryer will bring them back to life. Pro tip: skip the microwave—unless you’re into soggy bottoms (no judgment, but I can’t relate).

When to Serve Them

Breakfast, brunch, dessert, afternoon snack—basically anytime is turnover time. They also travel well, so bring them to a picnic, pack one for the office, or stash a secret pastry for yourself.

Sourdough Turnovers with Jam

If your sourdough starter has been giving you the side-eye from the back of the fridge, here’s your sign to turn that discard into something far more exciting than another loaf: flaky, buttery sourdough turnovers stuffed with your favorite jam. These golden little triangles bake up with tender, crisp edges, gooey fruit centers, and just enough tang from the starter to make you feel smug about your pastry skills. Perfect for brunch, tea time, or when you “accidentally” open a jar of jam and need a vehicle for it, this small-batch recipe makes six turnovers—enough to share, but no judgment if you don’t.
Servings 6 turnovers
Prep Time 1 hour 30 minutes
Cook Time 25 minutes

Ingredients

Crust

  • 142 grams (1 cup) all-purpose flour
  • 1.5 grams (¼ tsp) fine salt
  • 8 tbsp (1 stick) cold unsalted butter cut into pieces
  • 62 grams (½ cup) sourdough discard
  • 1-3 tbsp ice water

Filling

  • 6 tbsp jam, marmalade, or pie filling 1 tbsp per turnover

Egg Wash

  • 1 large egg
  • 1 tbsp heavy cream or milk

Instructions

  • Start the dough: Toss the flour and salt into a food processor and give it a quick pulse. Add the butter and pulse until you’ve got pea-sized bits. In goes the sourdough discard—pulse again until it’s mixed in.
  • Bring it together: Add ice water one tablespoon at a time, pulsing after each, just until the dough starts clumping together. Don’t overdo it—we’re going for “shaggy ball,” not “sticky mess.”
  • Chill out: Turn the dough out onto a floured surface, pat it into a puck, wrap it up with plastic wrap, and stash it in the fridge for at least an hour. (Overnight is fine. Freezing for future cravings? Also fine.)
  • Roll with it: When you’re ready, line a half sheet pan with parchment. Roll the dough into a rough 11×16-inch rectangle. If it starts to feel warm/floppy, pop it onto the sheet pan and chill for a few minutes, until firmed (see note). Trim the edges to a clean 10×15-inch rectangle, then cut into six 5×5-inch squares.
  • Fill ‘em up: Spread 1 tablespoon of filling over one diagonal half of each square, leaving a ½-inch border. Brush the edges with a little water, fold into triangles, and press to seal. Fork-crimp those edges for the classic turnover look, then slash the tops three times for steam vents. (Trim the crimped edges for a more polished look, or leave as-is and call them rustic).

  • Egg wash & bake: Preheat the oven to 400°F (200°C). Whisk the egg with cream or milk, brush over the tops, and bake for about 25 minutes, rotating halfway through, until golden-brown and puffed.
  • Cool & enjoy: Let them cool on a wire rack so you don’t burn your mouth on molten jam (ask me how I know). These turnovers stay flaky for about two days in an airtight container. After that, a quick 2-3 minutes in the toaster oven or air fryer will bring them back to life.

Notes

Tip: If your dough starts feeling floppy, send it to the fridge for a time-out. Warm pastry is a diva—it’s hard to work with and won’t give you those dreamy, flaky layers. Hot day? Frequent chill breaks are basically mandatory.
