Ingredients
For the Tart
1 sheet frozen puff pastry, thawed
2 medium sweet onions, thinly sliced
1 tablespoon unsalted butter
1 tablespoon olive oil
1 teaspoon brown sugar
1 teaspoon balsamic vinegar
4 ounces goat cheese, crumbled
2 tablespoons grated Parmesan cheese
1 teaspoon fresh thyme leaves
1 egg, beaten (for egg wash)
Salt and freshly ground black pepper, to taste
Optional Garnishes
Fresh arugula
Balsamic glaze
Hot honey
Chopped walnuts or pecans

Lemon zest
Flaky sea salt
Instructions
Step 1: Prepare the Oven
Preheat the oven to 425°F (220°C).
Line a baking sheet with parchment paper.
Step 2: Caramelize the Onions
Heat the butter and olive oil in a large skillet over medium-high heat.
Add the sliced onions and cook for 6–8 minutes, stirring occasionally, until softened and lightly caramelized.
Stir in:
Brown sugar
Balsamic vinegar
Cook for another 1–2 minutes until glossy.
Season with a pinch of salt and black pepper.
Step 3: Prepare the Puff Pastry
Unfold the thawed puff pastry onto the prepared baking sheet.
Using a knife, score a ½-inch border around the edges without cutting all the way through.
Prick the center of the pastry several times with a fork to prevent excessive puffing.
Brush the border with the beaten egg.
Step 4: Assemble the Tart
Spread the caramelized onions evenly over the center of the pastry, leaving the border uncovered.
Top with:
Crumbled goat cheese
Parmesan cheese
Fresh thyme leaves
Season lightly with black pepper.
Step 5: Bake
Bake for 12–15 minutes, or until the pastry is puffed and golden brown and the cheese is lightly browned.
Step 6: Garnish and Serve
Allow the tart to cool for 3–5 minutes.
Top with:
Fresh arugula
Balsamic glaze
A light drizzle of hot honey (optional)
Chopped walnuts
Fresh thyme
Flaky sea salt
Slice and serve warm.

Recipe Notes
Sweet onions caramelize more quickly than yellow onions, making them ideal for this fast recipe.
Use all-butter puff pastry for the richest flavor and flakiest texture.
Goat cheese softens beautifully in the oven while maintaining its creamy texture.
Expert Tips
Avoid overloading the pastry with toppings to keep the base crisp.
Chill the assembled tart for 5–10 minutes before baking if the pastry becomes too warm.
For extra color and flavor, finish with fresh herbs after baking.
Serve warm for the best texture and flavor.
Frequently Asked Questions
Can I make this ahead of time?
You can caramelize the onions up to 3 days ahead and refrigerate them. Assemble and bake the tart just before serving for the best results.
Can I use homemade puff pastry?
Yes! Homemade puff pastry works beautifully, though store-bought pastry is perfect for keeping this recipe quick.
Can I substitute the goat cheese?
Absolutely. Try feta, ricotta, creamy blue cheese, or Brie for a different flavor profile.
