Why You’ll Love These Caramelized French Onion Puff Pastry Twists
- Simple Ingredients: We’re using store-bought puff pastry for convenience, but the flavor payoff feels anything but simple. With a few grocery store staples—yellow onions, olive oil, butter, and cheese—you’ll create an impressive hors d’oeuvre.
- Perfect for Holiday Parties: These little bites are perfect for entertaining, and they’re easy to make ahead. Just pop them in a preheated oven when you’re ready to serve.
Ingredient Breakdown
- Unsalted Butter & Olive Oil: Using both butter and olive oil provides a great base for caramelizing the sliced onions, ensuring they cook evenly over medium heat.
- Yellow Onions: The key to a good caramelization. Cooking these with a bit of patience results in rich, balsamic caramelized onions.
- Kosher Salt & Sugar: Essential for drawing out moisture and adding a touch of sweetness to balance the onions.
- Brandy & Balsamic Vinegar: Deglazing with brandy lifts the fond from the pan, and a splash of balsamic vinegar adds a rich, tangy depth.
- Store-Bought Puff Pastry: Convenient and buttery, this is a lifesaver when you don’t have time to make a rough puff pastry recipe from scratch.
- Gruyère Cheese: Melty with a distinct flavor, gruyère’s nutty taste perfectly complements the onions, and gives the classic flavors of French Onion Soup. You could also try parmesan cheese or a different type of cheese for variety.
- Fresh Thyme Leaves: Herbaceous and aromatic, these fresh herbs tie everything together.
- Large Egg & Water: Combined for a simple egg wash that ensures a golden brown finish on your puff pastry twists.
- Ground Black Pepper: A final sprinkle adds just the right amount of spice.
How to Make Caramelized French Onion Puff Pastry Twists
Follow these simple steps, and you’ll have a crowd-pleasing appetizer that looks and tastes impressive!
Step 1: Caramelize the Onions
In a skillet or Dutch oven over medium-low heat, melt the butter and olive oil. Add the thinly sliced onions and sprinkle with kosher salt and sugar. Stir to coat the onions, then let them cook low and slow, stirring every five minutes.
Pro Tip: Be patient! It takes about an hour for the onions to fully caramelize. The magic happens in the last 15 minutes when they transform from golden to a deep, rich brown. Make sure to scrape up any fond from the bottom of the pot, as it adds incredible flavor.
Once caramelized, add the minced garlic and cook until fragrant (about 1 minute). Deglaze the pot with brandy, scraping up all those tasty brown bits, and let it reduce. Stir in the balsamic vinegar, remove the onions from the heat, and let them cool completely.
Step 2: Prepare the Puff Pastry
Preheat your oven to 400°F. On a lightly floured surface, roll out both sheets of puff pastry and cut each into a 12-inch circle using a sharp paring knife.
Tip: Keep your puff pastry cold until you’re ready to use it for the best results!
Step 3: Assemble the Twists
- Sprinkle one of the puff pastry circles with half of the shredded gruyère cheese. Lightly roll the cheese into the pastry so it sticks.
- Spread the cooled caramelized onions evenly over the cheese and sprinkle with fresh thyme leaves. Top with the remaining gruyère and the second puff pastry circle, pressing them together gently with your rolling pin.
- Transfer the puff pastry to a parchment-lined rimmed baking sheet.
Step 4: Cut & Twist
Place a cup in the center of the puff pastry and cut straight slits from the edge of the cup to the outside of the pastry, about an inch apart, creating strips. Remove the cup and twist each strip twice, pressing the ends into the parchment to hold their shape.
Step 5: Egg Wash & Bake
Whisk the egg with a teaspoon of water to make an egg wash. Brush the entire pastry with the egg wash, and sprinkle with freshly ground black pepper for a bit of heat. Refrigerate for 10 minutes to firm up the pastry.
Bake at 400°F until golden brown and puffed, about 20 minutes. Let the pastry cool slightly, and serve warm. These twists are perfect alongside a glass of wine or your favorite cocktail!
Serving Suggestions
- These cheese twists are best enjoyed warm. Serve them alongside a glass of wine or a hot honey dip for an extra kick.
- For a holiday party, consider pairing them with a flaky tart or puff pastry appetizers like mini French onion tarts. They’re also great as a side to soups or salads.
Tips & Variations
- Make Ahead: Caramelize the onions and store them in an airtight container in the fridge for up to 3 days. When ready to use, bring them to room temperature before assembling.
- Puff Pastry Scraps: Don’t waste any puff pastry scraps! Twist them and bake for a few minutes as a quick snack.
- Cheese Variations: While gruyère cheese offers a nutty flavor that pairs well with the onions, feel free to swap it out for Swiss cheese, parmesan cheese, or even a sharp cheddar for a different twist.
Frequently Asked Questions
Can I use homemade puff pastry?
Absolutely! Homemade puff pastry or a rough puff pastry recipe would make these twists even flakier and more delicious.

Can I make these in a different shape?
