Ingredients

(Tip: You can find the complete list of ingredients and their measurements in the recipe card below.)

• 1 sheet puff pastry, thawed

• 2 large onions, thinly sliced

• 2 tablespoons butter

• 1 tablespoon olive oil

• 1 teaspoon balsamic vinegar

• 1 teaspoon brown sugar

• 1/2 teaspoon salt

• 4 oz goat cheese

• 1 egg (for egg wash)

• Fresh thyme leaves (for garnish)

Directions

1. Preheat the oven to 400°F (200°C) and line a baking tray with parchment paper.

2. In a large skillet over medium heat, melt the butter with the olive oil. Add the sliced onions and cook slowly for 25–30 minutes, stirring occasionally, until they are deeply golden and soft.

3. Stir in the balsamic vinegar, brown sugar, and salt. Continue cooking for an additional 5 minutes until the onions are syrupy and fragrant. Remove from heat.

4. Roll out the puff pastry and use a round cutter to cut circles from the dough. Use a smaller cutter to score a border inside each round without cutting through—this helps the edges rise around the filling.

5. Place a teaspoon of caramelized onion in the center of each pastry round and top with a small dollop of goat cheese.

6. Brush the pastry edges with beaten egg.

7. Bake for 15–18 minutes, or until the pastry is puffed and golden.

8. Garnish with fresh thyme and serve warm.

Storage/Reheating

Store any leftovers in an airtight container in the refrigerator for up to 3 days.

FAQs

Can I make these puff pastry bites ahead of time?

Yes. You can caramelize the onions and cut the pastry rounds in advance. Assemble and bake just before serving for best results.

How do I prevent the pastry from getting soggy?

Ensure the onions are well caramelized and not too wet before adding to the pastry. Baking at high heat also helps crisp the dough.

Can I freeze them?

You can freeze the unbaked assembled bites. Bake directly from frozen, adding a few extra minutes to the bake time.

What’s the best goat cheese to use?

A soft, spreadable goat cheese works best. You can use herbed varieties for extra flavor.

Can I use store-bought caramelized onions?

Yes, if you’re short on time, pre-made caramelized onions can be a suitable substitute, though homemade offers the best flavor.

Is puff pastry the same as phyllo dough?

No. Puff pastry is thicker and flakier, while phyllo is thin and crisp. Phyllo is not recommended for this specific recipe.

Can I serve these at room temperature?

They’re best served warm, but they still taste good at room temperature. Reheat if needed for best texture.

Can I use red onions?

Yes, red onions add a slightly sweeter and more vibrant flavor and color.

Do I need to grease the baking sheet?

Parchment paper is usually sufficient, but you can lightly grease the tray if not using parchment.

How do I get a perfect golden crust?

Ensure you apply a generous, even coat of egg wash to the pastry edges before baking.
