Step‑by‑Step Instructions for Caramelized Onion and Goat Cheese Tarts
Step 1: Caramelize the Onions
In a large skillet, heat 2 tablespoons of olive oil and 1 tablespoon of butter over medium heat until shimmering. Add 3 sliced yellow onions along with 1 tablespoon of sugar, and season with salt and pepper. Fry gently for 15-20 minutes, stirring occasionally, until the onions become golden brown and jammy. Finally, stir in 1 tablespoon of balsamic vinegar and a sprinkle of thyme, cooking for an additional 5 minutes to deepen the flavors.
Step 2: Prepare the Pastry
While the onions are caramelizing, lightly flour a clean surface and roll out one sheet of frozen puff pastry to about ¼ inch thick. Cut the pastry into 6 equal rectangles to form the base of your Caramelized Onion and Goat Cheese Tarts. Ensure the edges are slightly thicker for a defined crust, and transfer them to a parchment-lined baking sheet to ready them for assembly.
Step 3: Assemble Tarts
Once the onion mixture has cooled slightly, spread a generous layer of caramelized onions evenly over each pastry rectangle, leaving about a ½ inch border around the edges. Crumble 4 ounces of goat cheese on top of the onions, allowing the creamy tang to blend beautifully with the sweet toppings. For an extra touch, feel free to scatter additional thyme leaves before proceeding to the next step.
Step 4: Bake
Preheat your oven to 400°F (200°C). Bake the assembled tarts in the preheated oven for about 15 minutes, or until they are puffed up and golden brown. Keep an eye on the pastries, as they should be beautifully crisp and flaky when they’re ready. Once done, remove them from the oven and allow them to cool slightly on the baking sheet before serving to enjoy the delightful contrast of textures in your Caramelized Onion and Goat Cheese Tarts.

How to Store and Freeze Caramelized Onion and Goat Cheese Tarts
Fridge: Store leftover tarts in an airtight container for up to 2 days to maintain freshness.
Freezer: For longer storage, freeze the assembled but unbaked tarts. Wrap tightly in plastic wrap and foil; they can last up to 3 months.
Reheating: For the best results, reheat baked tarts in a 350°F oven for 5-7 minutes to restore crispness. Avoid microwaving, as it can lead to sogginess.
Make-Ahead: You can prepare the filling and pastry in advance. Assemble the Caramelized Onion and Goat Cheese Tarts right before baking for optimal taste and texture.

Caramelized Onion and Goat Cheese Tarts Recipe FAQs
What type of onions should I use for caramelizing?
For the best results in your Caramelized Onion and Goat Cheese Tarts, I recommend using yellow onions as they caramelize beautifully, becoming sweet and jammy. If you prefer a sharper taste, feel free to swap in red onions. The key is to be patient—let them cook slowly for rich flavor.
How long can I store the tarts in the fridge?
You can store leftover tarts in an airtight container for up to 2 days. To keep them fresh and flavorful, make sure they’re completely cooled before placing them in the container. If you find them losing crispness, reheat them in a 350°F oven for about 5-7 minutes to regain that delightful flaky texture.
Can I freeze the tarts?
Absolutely! For longer storage, I often freeze the assembled but unbaked tarts. Simply wrap each tart tightly in plastic wrap, then in foil to prevent freezer burn. They can be frozen for up to 3 months. When you’re ready to enjoy, bake them directly from the freezer—just add a few extra minutes to their baking time!
What if my caramelized onions are too soggy?
No worries! If your onions turn out too soggy, you may not have cooked them long enough to release their moisture. To fix this, return your cooked onions to the pan over low heat to evaporate excess liquid. Stir occasionally over low heat until they are thickened and jammy. Then, proceed with assembling your tarts!
Are these tarts suitable for people with dietary restrictions?
Yes! These Caramelized Onion and Goat Cheese Tarts can be adjusted for various dietary needs. For a dairy-free option, substitute butter with olive oil and use a dairy-free cheese. Just keep an eye on ingredient labels for any allergens. They’re perfect for vegetarian diets and can be made nut-free with proper cheese choices.
