Ingredients
Caramelized Onion Mixture
- 2 tablespoons olive oil
- 2 medium sweet onions, thinly sliced
- 1 teaspoon kosher salt
- 1 apple, diced small
- 1 tablespoon fresh thyme leaves or 1 teaspoon dried thyme
- 1 tablespoon balsamic vinegar
- ¼ cup apple jelly
Goat Cheese Mixture
- 4 ounces goat cheese, softened
- 2 tablespoons heavy cream
Puff Pastry Tart Shells
- 1 sheet frozen puff pastry, thawed
- Additional fresh thyme for topping
Instructions
- Caramelize the Onions: Heat 2 tablespoons of olive oil in a large pan over medium heat. Add the thinly sliced onions and 1 teaspoon kosher salt. Cook, stirring occasionally, for about 15-20 minutes until the onions turn a rich golden brown. If the onions start to dry out or stick, add a splash of water and deglaze the pan by scraping the bottom.
- Add Apples and Thyme: Lower the heat to medium-low and stir in the diced apple and thyme leaves. Continue cooking for an additional 5 minutes until the apples are tender.
- Finish Onion Mixture: Stir in the balsamic vinegar and apple jelly until well combined. Remove the pan from heat and allow the mixture to cool.
- Prepare the Goat Cheese Mixture: In a small bowl, mix the softened goat cheese with heavy cream until smooth and creamy.
- Preheat Oven and Prep Puff Pastry: Preheat oven to 375°F (190°C). Roll out the thawed puff pastry sheet into a 10×15 inch rectangle and cut into 24 equal squares, approximately 2.5 inches each.
- Assemble Tarts: Generously grease a 24-cup mini muffin tin. Fit each puff pastry square into the muffin cavities, forming little cups.
- Fill and Top: Evenly divide the cooled onion mixture among the pastry cups, then add a dollop of the goat cheese mixture on top of each.
- Bake: Bake the tarts in the preheated oven for 20-22 minutes until the puff pastry is golden brown and the cheese is slightly browned.
- Remove Tarts Carefully: Immediately after baking, use a butter knife to gently lift the tarts out of the pan while still hot to prevent the sticky syrup from hardening and sticking.
- Cool and Serve: Let the tarts cool for about 10 minutes before serving, allowing the filling to set and cool slightly. Garnish with fresh thyme and serve warm.
Notes
- Be patient when caramelizing onions; slow cooking develops deeper flavor.
- The splash of water during caramelization prevents burning and helps scrape flavorful bits from the pan.
- Ensure the puff pastry is well thawed for easy rolling and cutting.
- Removing the tarts while hot makes releasing them easier and preserves their delicate texture.
- These tarts can be served warm or at room temperature and are great for entertaining.
- For a dairy-free version, substitute goat cheese with a plant-based cream cheese alternative.
