Ingredients
Scale
Main Ingredients:
- 1 sheet thawed puff pastry
- 18 thin slices gruyere cheese
- 1 yellow onion, cut into thin rings
Aromatics and Seasonings:
- 2 sprigs fresh thyme
- 3 tablespoons (44 milliliters) honey, divided
- Sea salt to taste
- Black pepper to taste
Egg Wash:
- 1 large egg for washing
Instructions
- Preheat the oven to 400°F and line a baking sheet with parchment paper, creating a clean surface for the tarts.
- Drizzle 9 small pools of honey evenly across the parchment paper, creating a sweet foundation for each tart.
- Slice pastry into 9 uniform squares, ensuring consistent sizing for even baking.
- Sprinkle fresh thyme leaves, salt, and cracked black pepper over the honey pools to enhance the flavor profile.
- Carefully place a single onion slice and two pieces of gruyere cheese atop each honey-seasoned pool, creating a layered base.
- Gently cover each layered stack with a prepared pastry square, ensuring complete coverage of the ingredients.
- Brush the pastry tops with beaten egg, which will help achieve a golden, glossy finish during baking.
- Transfer the baking sheet into the preheated oven and bake for 20 minutes, watching for a puffy, rich golden-brown color.
- Once baked, delicately flip the tarts to reveal their caramelized bottom layer.
- Garnish with additional honey drizzle and fresh thyme sprigs for an elegant touch.
- Allow tarts to cool for 5 minutes before serving to let flavors meld and prevent burning.
Notes
- Select sweet onions like Vidalia for a milder, caramelized flavor profile that complements the rich gruyere cheese.
- Use cold, high-quality butter puff pastry to ensure maximum flakiness and crisp edges during baking.
- Slice onions uniformly thin to guarantee even cooking and consistent texture across all tarts.
- Try herb variations like rosemary or sage for different aromatic twists on the classic thyme flavor.
