Ingredients
Scale
Pastry
- 1 sheet puff pastry (thawed)
Vegetables & Toppings
- 2 medium sweet potatoes (peeled and thinly sliced)
- 1 large red onion (thinly sliced)
- 1/2 cup crumbled feta cheese
- 1 teaspoon fresh thyme leaves (or 1/2 teaspoon dried)
Other Ingredients
- 2 tablespoons olive oil (divided)
- 1 tablespoon balsamic vinegar
- 1 teaspoon brown sugar
- Salt and black pepper to taste
- 1 egg (beaten, for egg wash)
- Optional honey drizzle for serving
Instructions
- Preheat and Prepare Baking Sheet: Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper to prevent sticking and make cleanup easier.
- Caramelise the Onions: In a skillet over medium heat, add 1 tablespoon of olive oil and the thinly sliced red onion. Cook for 10–12 minutes, stirring occasionally, until the onions are softened and golden brown. Then stir in the balsamic vinegar and brown sugar, cooking for another 2 minutes to deepen the sweetness and flavor. Remove from heat once done.
- Prepare Sweet Potatoes: Toss the thinly sliced sweet potatoes with the remaining tablespoon of olive oil, and season with salt and black pepper to taste to enhance their natural sweetness and flavor.
- Prepare the Puff Pastry Base: Place the thawed puff pastry sheet on the prepared baking sheet. Using a knife, score a 1-inch border around the edges without cutting all the way through, which will help the edges puff up nicely while baking.
- Assemble the Tart: Inside the scored border, evenly layer the olive oil-coated sweet potato slices. Then top with the caramelised onions, crumbled feta cheese, and sprinkle the fresh thyme leaves evenly over the top for an herbaceous note.
- Apply Egg Wash: Brush the exposed pastry edges with the beaten egg to give the crust a glossy, golden finish once baked.
- Bake the Tart: Bake in the preheated oven for 25–30 minutes or until the puff pastry is golden and puffed and the sweet potatoes are tender when pierced with a fork.
- Serve: Optionally drizzle with honey to add a sweet-savory balance just before serving. Serve warm or at room temperature as a flavorful vegetarian main or appetizer.
Notes
- You can prepare this tart ahead of time and reheat it before serving without loss of flavor or texture.
- This tart makes a great vegetarian main course or a savory appetizer at any gathering.
- For a dairy-free version, omit the feta or substitute with a plant-based cheese alternative.
- The optional honey drizzle adds a nice sweet contrast, but can be omitted for a less sweet dish.
