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. Add 2 thinly sliced onions, along with 1 tablespoon of sugar, salt, and pepper to taste. Cook the mixture undisturbed for about 15-20 minutes or until the onions turn a deep golden color and become jammy. Stir in 1 tablespoon of balsamic vinegar and a sprinkle of fresh thyme, cooking for an additional 2 minutes until fragrant.
Step 2: Prepare the Puff Pastry
While the onions are caramelizing, preheat your oven to 400°F (200°C). On a lightly floured surface, roll out a sheet of thawed puff pastry until it’s about 1/8 inch thick. Use a sharp knife to cut the pastry into rectangles or desired shapes, ideally about 4 inches in size. Transfer the cut pastry onto a parchment-lined baking sheet, creating a slight border around each piece.
Step 3: Assemble the Tarts
Once the onions are caramelized and slightly cooled, spread a generous amount over each piece of puff pastry. Crumble fresh goat cheese on top of the onions, adding extra thyme if desired for more flavor. Make sure not to overload the pastry to ensure a crispy finish. The combination of caramelized onion and goat cheese will create a delightful topping for your tarts.
Step 4: Bake the Tarts
Place the assembled tarts in your preheated oven and bake for 15-20 minutes, watching carefully until they puff up and achieve a beautiful golden brown color. The edges should be flaky, and the filling should begin to bubble slightly. This step is crucial for achieving the perfect texture and flavor in your Caramelized Onion and Goat Cheese Tarts.
Step 5: Cool & Serve
Once baked, remove the tarts from the oven and allow them to cool for a few minutes on the baking sheet. This brief cooling time helps to set the filling. Serve your Caramelized Onion and Goat Cheese Tarts warm, either on their own or with a light salad. Enjoy the exquisite blend of flavors that makes these tarts a standout appetizer!

Caramelized Onion and Goat Cheese Tarts Recipe FAQs
What kind of onions should I use for the best flavor?
Absolutely! Yellow onions are the best choice for caramelizing as they bring out the natural sweetness and have the right balance of flavor. Avoid using overly pungent onions, like red onions, as they might dominate the taste.
How should I store leftover tarts?
To keep leftover Caramelized Onion and Goat Cheese Tarts fresh, place them in an airtight container in the fridge. They’ll be good for up to 2 days. Just pop them in a 350°F oven for 5-7 minutes before serving to restore their crispiness!
Can I freeze the tarts? If so, how?
Very! You can freeze unbaked tarts for up to 2 months. After assembling, wrap each tart tightly in plastic wrap, then in aluminum foil to prevent freezer burn. When you’re ready to bake, there’s no need to thaw; just pop them straight into a preheated oven, adding a few extra minutes to the baking time.
What if my tarts come out soggy?
If your tarts end up soggy, it’s likely from too much filling or the onions being too hot when assembled.
