Ingredients
List of Ingredients
- 1 sheet of puff pastry, thawed
- 3 large onions, thinly sliced
- 2 tablespoons olive oil
- 1 tablespoon sugar
- 1 teaspoon balsamic vinegar
- 1 teaspoon fresh thyme leaves, chopped
- 6 ounces goat cheese, crumbled
- Salt and pepper to taste
- 1 egg, beaten (for egg wash)
- Fresh thyme sprigs for garnish (optional)
Recommended Quality of Ingredients
I always choose fresh and high-quality ingredients. Fresh onions are key for great flavor. Look for onions with smooth skins and no blemishes. Use good olive oil for sautéing as it adds depth. For the goat cheese, select a creamy variety for the best texture. Fresh thyme is a must; dried thyme won’t give the same taste.
Possible Substitutions
If you need alternatives, here are some ideas. Instead of goat cheese, you can use feta or ricotta for a different flavor. For the olive oil, any cooking oil can work, but olive gives a nice touch. You can swap balsamic vinegar with apple cider vinegar if needed. If you don’t have thyme, rosemary can add a unique twist.

Step-by-Step Instructions
Prepping the Onions
Start by heating olive oil in a large skillet over medium heat. Add the thinly sliced onions. Cook them for about 10 minutes until they soften. Then, sprinkle in the sugar. Lower the heat to medium-low. Stir the onions every few minutes for 20-25 minutes. They should turn golden brown and smell sweet. Add balsamic vinegar and fresh thyme. Cook for another 2 minutes. Season with salt and pepper to taste. Let the onions cool a bit before you move on.
Assembling the Tart
Roll out the puff pastry on a floured surface. You want it to fit your tart pan, about 9 inches wide. Place the pastry in the pan and prick the bottom with a fork. This helps stop it from puffing too much while baking. Now, spread the caramelized onion mixture evenly over the pastry. Crumble the goat cheese on top of the onions. Make sure to cover the onions well. Brush the edges of the pastry with beaten egg. This gives the tart a lovely golden finish.
Baking Techniques
Preheat your oven to 400°F (200°C). Once your tart is ready, place it in the oven. Bake it for 25-30 minutes. The pastry should be golden brown and puffed up. After baking, let the tart cool for a few minutes. This makes slicing easier. If you like, add fresh thyme sprigs on top for a nice touch. Enjoy the mix of flavors and the crisp texture!
Tips & Tricks
Perfecting Caramelization
To get the best flavor, take your time with the onions. Start by slicing three large onions thinly. Heat two tablespoons of olive oil in a skillet over medium heat. Add the onions and cook for about ten minutes. They should start to soften. Then, sprinkle in one tablespoon of sugar. This helps them caramelize better. Lower the heat to medium-low. Stir often and cook for 20 to 25 minutes. Watch for that rich, golden brown color. At the end, add one teaspoon of balsamic vinegar and one teaspoon of fresh thyme. This adds great depth to the flavor. Season with salt and pepper to taste.
Achieving the Ideal Puff Pastry Texture
For a perfect puff pastry, use a thawed sheet. Roll it out on a lightly floured surface. Make sure it fits your tart pan, about nine inches wide. Prick the bottom with a fork. This helps prevent puffing during baking. Brush the edges with a beaten egg. This gives it that nice golden finish. Bake it at 400°F (200°C) for 25 to 30 minutes. Watch for a beautiful puff and golden brown color. This makes the tart look and taste fantastic.
Serving Suggestions
Serve your tart warm or at room temperature. It pairs well with a fresh salad. Consider a simple arugula salad with lemon dressing. You can also serve it as an appetizer at a party. Cut it into small squares for easy eating. Garnish with fresh thyme sprigs for a nice touch. Enjoy your delicious creation!
Pro Tips
- Use Sweet Onions: Sweet onions like Vidalia or Walla Walla enhance the natural sweetness of the tart and caramelize beautifully.
- Don't Rush the Caramelization: Allow the onions to cook slowly over medium-low heat. This will develop a rich flavor and deep color.
- Experiment with Cheese: While goat cheese is delicious, try mixing in some feta or cream cheese for added creaminess and flavor complexity.
- Serve Warm: This tart is best served warm, so consider making it just before serving or reheating it slightly in the oven.
Variations
Adding Other Cheeses
You can mix in different cheeses for more flavor. Try feta for a salty bite. Or add sharp cheddar for a richer taste. Cream cheese can make the tart creamy and smooth. Each cheese brings its own fun twist to the dish.
Vegetarian Add-Ins
Want to make your tart even heartier? Add some veggies! Spinach works great. It adds color and nutrients. You can also toss in roasted red peppers for a sweet touch. Don’t forget mushrooms; they add a nice umami flavor. These add-ins keep it fresh and interesting.
Seasonal Ingredient Swaps
Change up your tart with seasonal ingredients. In spring, add asparagus for a bright crunch. Summer is perfect for fresh tomatoes. They add juiciness and a pop of color. In fall, swap in roasted butternut squash for a sweet flavor. Winter is great for adding kale, which adds texture. Using seasonal ingredients makes your tart taste even better.
