Ingredients
1 sheet of puff pastry (thawed)
2 large yellow onions (thinly sliced)
3 tablespoons unsalted butter
1 tablespoon olive oil
1 teaspoon sugar
1 teaspoon fresh thyme (or ½ teaspoon dried thyme)
4 ounces goat cheese (crumbled)
1 large egg
1 tablespoon heavy cream
Salt and pepper to taste
Fresh thyme sprigs for garnish (optional)
Balsamic glaze for drizzling (optional)
Instructions
- Preheat your oven to 375°F (190°C).
- In a large skillet, melt the butter and olive oil over medium heat. Add the thinly sliced onions, salt, and sugar. Stir frequently and cook for about 20-25 minutes, or until the onions are soft and golden brown. Stir in thyme during the last 5 minutes of cooking.
- On a lightly floured surface, roll out the thawed puff pastry to fit a 9-inch tart pan. Press it into the pan, trim any excess pastry, and prick the bottom with a fork to prevent puffing during baking.
- Spread the caramelized onions evenly over the prepared puff pastry. Sprinkle crumbled goat cheese on top.
- In a small bowl, whisk together the egg and heavy cream. Season with salt and pepper, then pour evenly over the tart.
- Bake the tart for 25-30 minutes, or until the pastry is golden brown and the egg mixture is set.
- Remove from the oven and let cool for a few minutes. Optionally garnish with fresh thyme sprigs and drizzle with balsamic glaze before serving. Serve warm or at room temperature.
Notes
- Herb Variations: Try using fresh rosemary, sage, or oregano instead of thyme for a unique flavor.
- Cheese Options: Goat cheese can be substituted with feta, cream cheese, or ricotta for different flavor profiles.
- Vegetables: Add roasted vegetables like bell peppers, zucchini, or mushrooms for extra flavor.
- Storage: Store leftovers in an airtight container in the fridge for up to 3 days. Reheat in a 350°F oven for about 10 minutes.
- Freezing: Freeze the tart before baking for up to 1 month. Bake directly from the freezer, adding extra time.
- Gluten-Free: Use gluten-free puff pastry to make this tart suitable for gluten-sensitive diets.
