Flaky, buttery puff pastry twisted with sweet, deeply caramelized onions, melted nutty Gruyère cheese, and a hint of fresh thyme. A perfect elegant appetizer or savory snack.
Ingredients
Caramelized Onions
- 2 large Yellow onions — Thinly sliced
- 1 tablespoon Unsalted butter
- 1 tablespoon Olive oil
- 1 teaspoon Fresh thyme — Chopped
- 1 teaspoon Balsamic vinegar
- 0.5 teaspoon Kosher salt — Plus more to taste
Pastry & Assembly
- 1 sheet Puff pastry — Thawed if frozen
- 1.5 cups Gruyère cheese — Freshly grated
- 1 large Egg — Beaten with 1 tbsp water for egg wash
Instructions
-
Melt the butter and olive oil in a large skillet over medium-low heat. Add the sliced onions and salt. Cook slowly, stirring occasionally, until deeply golden and caramelized, about 40-45 minutes. If they start to dry out, add a splash of water.
~45 minPatience is key for caramelizing onions. Keep the heat low to prevent burning. -
Stir in the fresh thyme and balsamic vinegar into the onions. Cook for 1 more minute, then remove from heat. Spread the onions on a plate to cool completely. Do not use warm onions on the puff pastry or it will melt the butter in the dough.
~1 minCooling the onions in the fridge for 10 minutes speeds up this process. -
Preheat your oven to 400°F (200°C). Line a large baking sheet with parchment paper.
~5 min -
On a lightly floured surface, gently roll out the puff pastry sheet into a 10x12-inch rectangle. Visually divide the pastry in half horizontally.
~3 min -
Evenly distribute the cooled caramelized onions over the bottom half of the pastry, spreading them in a thin, even layer to the edges. Sprinkle the grated Gruyère evenly over the onions.
~2 minAvoid large clumps of filling, which makes the dough harder to twist. -
Fold the top half of the pastry over the filling. Press down gently but firmly with your hands or lightly with a rolling pin to seal the two layers together.
~1 minChill the filled pastry block in the fridge for 10-15 minutes at this stage to make cutting and twisting much easier. -
Using a pizza cutter or a sharp knife, cut the filled pastry vertically into 12 equal strips (about 1 inch wide each).
~2 min -
Take one strip by the ends and gently twist it in opposite directions 3-4 times to form a spiral. Place on the prepared baking sheet, pressing the ends down slightly so they don't unravel. Repeat with the remaining strips.
~5 minIf the dough feels too soft and starts tearing, pop the pan into the freezer for 5 minutes. -
Brush the tops of the twists lightly with the egg wash.
~1 min -
Bake for 15-18 minutes, or until the pastry is puffed, deeply golden brown, and the cheese is crisp and bubbly. Let cool on the pan for 5 minutes before serving.
~15 minWatch closely at the 12-minute mark, as the cheese on the baking sheet can brown quickly.

Tips & Storage
- Ensure your puff pastry stays as cold as possible throughout the process for maximum flakiness.
- You can make the caramelized onions up to 3 days in advance and store them in the fridge.
- Add a pinch of cayenne pepper or a teaspoon of Dijon mustard to the egg wash for an extra kick.
- Storage: Store leftover twists in an airtight container in the refrigerator for up to 3 days. Reheat in a 350°F (175°C) oven for 5-7 minutes until crisp. Do not microwave, as they will become soggy.
