How to Make Caramelized Onion and Goat Cheese Tarts
Follow these easy steps for perfect results.
Step 1: Caramelize the Onions
This is the heart of the recipe.
- Heat olive oil and butter in a large skillet over medium heat.
- Add thinly sliced onions.
- Sprinkle with salt and cook, stirring occasionally.
Slow Cooking Is Key
Cook for 20–25 minutes until:
- Onions are soft
- Color turns deep golden brown
- Texture becomes jammy
Add Sweetness and Depth
- Stir in sugar.
- Add balsamic vinegar.
- Cook 2–3 more minutes.
The vinegar enhances sweetness and adds subtle acidity.
Remove from heat and let cool slightly.
Step 2: Prepare the Puff Pastry
- Preheat oven to 400°F (200°C).
- Line a baking sheet with parchment paper.
- Roll out puff pastry slightly on a lightly floured surface.
- Cut into squares or rectangles (about 4–6 portions).
Create a Border
- Use a knife to score a ½-inch border around each piece.
- Don’t cut all the way through.
- This helps create a raised crust edge.
Prick the center lightly with a fork to prevent over-puffing.
Step 3: Assemble the Tarts
- Spoon caramelized onions evenly into the center area.
- Sprinkle crumbled goat cheese on top.
- Add fresh thyme leaves.
- Season lightly with pepper.
Keep toppings within the scored border.
Step 4: Bake to Golden Perfection
- Bake for 15–20 minutes.
- Puff pastry should be golden brown.
- Cheese will soften but not fully melt.
Let cool slightly before serving.
Tips for Perfect Caramelized Onion and Goat Cheese Tarts
Don’t Rush the Onions
Proper caramelization takes time. High heat will burn rather than sweeten them.
Keep Puff Pastry Cold
Warm pastry becomes sticky and won’t puff properly.
Use Parchment Paper
Prevents sticking and ensures even baking.
Avoid Overloading
Too much topping can weigh down the pastry.

Storage & Reheating Instructions
