Create Your Caramelized Onion Goat Cheese Tarts Step-by-Step
Making caramelized onion goat cheese tarts is surprisingly simple. Just a few fresh ingredients and some easy steps will yield impressive results that everyone will adore.
Gather the Ingredients
To make these delightful tarts, you’ll need the following:

| Goat cheese | 8 ounces |
| Onions | 2 large, sliced |
| Puff pastry | 1 package (14 ounces) |
| Olive oil | 2 tablespoons |
| Fresh thyme | 1 teaspoon, chopped |
| Salt | To taste |
| Pepper | To taste |
Step 1
Preheat your oven to 400°F (200°C). Prepare a baking sheet by lining it with parchment paper. This will help the tarts to cook evenly and prevent sticking.
Step 2
Heat the olive oil in a skillet over medium heat. Add the sliced onions and a pinch of salt, cooking slowly to caramelize them, stirring occasionally. This process may take about 15 minutes, but it’s worth the wait. The onions should turn a beautiful golden brown.

| Cook time | 20 minutes |
| Store time | 3 days in the fridge |
Step 3
While the onions are cooking, roll out the puff pastry on a floured surface. Cut the pastry into squares based on the size you want for each tart. If using pre-rolled pastry, simply cut it into squares or circles.
After the onions are done, add the chopped thyme, and mix thoroughly. Start assembling the tarts by placing a dollop of the caramelized onion mixture in the center of each pastry piece, then topping it with crumbled goat cheese. Be sure to leave a border around each tart for the crust to puff up beautifully.
Transfer the tarts carefully onto the prepared baking sheet and bake in the preheated oven for about 15 minutes, or until the pastry is golden brown and puffed. Keep an eye on them to prevent burning.
Once done, remove from the oven and let them cool slightly before serving. These tarts are delightful served warm or at room temperature, making them perfect for any occasion.

As with any recipe, a few common pitfalls can happen. I always remind myself to be mindful of these to achieve the best results. Let’s explore some mistakes to avoid and pro tips that can help along the way.
