Ingredients You’ll Need
This recipe uses just a few ingredients, each bringing something special to the table. The puff pastry creates that irresistible flaky base, while caramelized onions and goat cheese steal the show.
Main Ingredients
- 1 sheet puff pastry, thawed – gives a buttery, flaky crust
- 2 large onions, thinly sliced – the star for that deep sweetness
- 2 tbsp olive oil – helps the onions cook slowly and evenly
- 1 tbsp butter – adds richness to the caramelization
- 1 tsp sugar – enhances the natural sweetness of the onions
- 1 tsp balsamic vinegar – adds a hint of tang and depthµ
- 4 oz goat cheese, crumbled – creamy and slightly tart contrast
- 1 tsp fresh thyme leaves – brings brightness and aroma
- Salt and pepper – to taste, balancing every bite
Optional Add-Ons or Substitutes
- Swap goat cheese for feta if you prefer a bolder flavor

- Use puff pastry squares to create mini tarts for parties
- Sprinkle toasted pine nuts on top for crunch

Step-by-Step Instructions
I love recipes that feel fancy but stay simple. These tarts are all about timing and layering—caramelize the onions, build your base, and bake to golden perfection.
- Caramelize the onions.
In a large skillet, heat olive oil and butter over medium-low heat. Add onions, salt, pepper, and sugar. Stir occasionally and cook for 20–25 minutes, until soft and golden brown. Stir in balsamic vinegar and cook for 2 minutes more. (The slower you cook them, the sweeter they’ll get.) - Assemble the tarts.
Preheat oven to 400°F. Roll out the puff pastry on a floured surface and cut into 4 equal squares. Place on a parchment-lined baking sheet. Spoon the caramelized onions evenly onto each square, leaving a small border. Top with crumbled goat cheese and a sprinkle of thyme. - Bake and serve.
Brush the edges of the pastry with olive oil and bake for 18–20 minutes, or until golden and puffed. Let cool slightly before serving. (They taste just as good warm as they do at room temperature.)
Quick reminders:
- Keep the puff pastry cold for the best rise
- Slice onions thin and cook low and slow for deep flavor
- Don’t overload the tarts—less is more
- Use parchment paper for easy cleanup
Expert Tips for Success
Even though this recipe is easy, a few small details will help you nail it every time.
- Use sweet yellow onions—they caramelize beautifully
- Don’t rush the onions; patience builds flavor
- Add a pinch of salt early to draw out moisture
- Let puff pastry thaw just until flexible, not soft
- Brush pastry edges with oil for a deep golden color
- Crumble goat cheese by hand for natural texture
- Reheat in the oven to bring back the crispiness
If you love elegant bites like my Bruschetta Dip Recipe or Cranberry Brie Cinnamon Puff Pastry Swirls, you’ll find these tarts hit that same sweet spot—simple, stylish, and full of flavor.

Storing and Reheating
You can easily make these tarts ahead or save leftovers—they reheat beautifully.
How to Store It

- Freeze baked tarts for up to 2 months
- Always cool completely before freezing to keep the pastry crisp
How to Reheat It
- Reheat in a 375°F oven for 8–10 minutes until crisp and warm
- Avoid microwaving—it softens the pastry

Even after reheating, these Onion and Goat Cheese Tarts stay flaky, buttery, and flavorful—just like freshly baked.
