How to Make Onion and Goat Cheese Tarts
-
Heat olive oil and butter in a large pan over medium heat. Add the sliced onions, sugar, salt, and pepper. This combination creates the foundation for that rich, sweet flavor you desire.

Cook undisturbed for 5 minutes. Then, stir occasionally for about 15 minutes until the onions turn golden brown. Add the balsamic vinegar and thyme, cooking for another 5 minutes until the mixture is jammy and fragrant.
-
Roll out the puff pastry on a floured surface. Cut it into rectangles and refrigerate for 10 minutes. This chilling step ensures a perfectly flaky texture once baked.
-
Spread the cooled caramelized onions evenly over each pastry rectangle. Crumble the goat cheese on top and sprinkle with extra thyme, allowing those flavors to meld beautifully.

Bake in a preheated 400°F oven for approximately 15 minutes. Check every 2 minutes after that until the pastry is golden and puffed up. Your kitchen will smell simply divine!

Make Ahead Options
These Onion and Goat Cheese Tarts are perfect for busy home cooks seeking to save time! You can prepare the caramelized onions up to 3 days in advance; just refrigerate them in an airtight container. Additionally, you can roll out the puff pastry and cut it into rectangles up to 24 hours ahead of time, keeping them wrapped in the fridge to maintain their flakiness. When you’re ready to serve, simply spread the chilled caramelized onions on the pastry, crumble the goat cheese on top, and bake. Following these steps ensures your tarts remain just as delicious and impressive, making your meal planning smoother and stress-free.
Storage Tips for Onion and Goat Cheese Tarts
Room Temperature: Enjoy your tarts fresh out of the oven, but if you have leftovers, you can leave them at room temperature for up to 2 hours before storing.
