Caramelized Onions
- 2 large onions, thinly sliced
- 2 tbsp olive oil
- 1 tbsp butter
- 1 tsp sugar
- Salt and pepper to taste
- 1 tsp balsamic vinegar
- 1 tsp fresh thyme leaves
Topping
- 4 oz goat cheese, crumbled
Instructions
- Preheat and Prepare Pan: Preheat your oven to 400°F (200°C) to ensure it reaches the right temperature for baking the tarts to a perfect golden brown.
- Caramelize Onions: In a pan over medium heat, warm the olive oil and butter together. Add the thinly sliced onions along with sugar, salt, and pepper. Cook gently, stirring occasionally, for about 20 minutes until the onions become soft, sweet, and richly caramelized. Stir in the balsamic vinegar and fresh thyme leaves, then remove the pan from heat to prevent overcooking.

Notes
- Ensure your puff pastry is fully thawed for easier handling and better rising.
- If you prefer a milder onion flavor, cook onions for less time but they won’t be as sweet and deeply caramelized.
- Feel free to sprinkle extra fresh thyme on top before serving for enhanced aroma.
- These tarts can be made ahead and reheated gently in the oven to preserve their crispiness.
- For a vegan version, substitute goat cheese with vegan cheese and butter with a plant-based alternative.
