Ingredients

• 2 large sweet potatoes, peeled and thinly sliced
• 1 large onion, thinly sliced
• 2 tablespoons olive oil
• 1 teaspoon salt
• 1/2 teaspoon black pepper
• 1/2 teaspoon dried thyme
• 200g feta cheese, crumbled
• 1 sheet of frozen puff pastry, thawed
• 1 egg, beaten (for egg wash)
• Fresh parsley, chopped (for garnish)

Instructions

1. Step 1: Prepare the Sweet Potatoes and Onions – Preheat your oven to 200°C (400°F). In a large bowl, toss the sliced sweet potatoes with a drizzle of olive oil, salt, pepper, and thyme until they are evenly coated. Spread them out on a baking sheet and roast in the oven for about 20 minutes, or until they are tender and lightly browned. Meanwhile, in a large skillet, cook the sliced onions over medium-low heat with a tablespoon of olive oil. Stir occasionally, allowing the onions to caramelise and turn golden brown, which should take about 30 minutes.
2. Step 2: Assemble the Tart – On a lightly floured surface, roll out the puff pastry to a large rectangle, about 1/4 inch thick. Transfer the pastry to a baking sheet lined with parchment paper. Leaving a 1-inch border around the edges, arrange the roasted sweet potatoes and caramelised onions in a pattern that suits your aesthetic. Top with crumbled feta cheese.
3. Step 3: Fold and Brush the Pastry – Fold the edges of the pastry up over the filling, pressing gently to seal. Brush the pastry with the beaten egg for a golden glaze.
4. Step 4: Bake the Tart – Bake the tart in the preheated oven for about 25-30 minutes, or until the pastry is golden brown and the filling is heated through. Remove from the oven and let it cool slightly before serving. Garnish with chopped fresh parsley.

Handy Tips

• To enhance the flavor of the caramelised onions, add a pinch of salt and a grind of black pepper halfway through the cooking process.
• For an extra crispy pastry, chill the assembled tart in the refrigerator for 10 minutes before baking.
• Consider adding some dried or fresh herbs like rosemary or oregano to the sweet potatoes for an additional depth of flavor.

Heat Control

When baking the tart, it’s crucial to maintain a consistent oven temperature to ensure that the pastry cooks evenly and the filling heats through without burning. Keep an eye on the tart during the last 10 minutes of baking, as the pastry can quickly go from perfectly golden to overly browned.

Crunch Factor

Achieving the right crunch factor in this tart comes down to the pastry. To ensure it remains crispy, avoid overfilling the tart, as this can make the pastry soggy. Additionally, chilling the tart before baking can help the pastry hold its shape and bake up crisper.

Pro Kitchen Tricks

• Use high-quality ingredients, especially the feta cheese, as it will significantly impact the overall flavor of the tart.
• Don’t overwork the puff pastry, as this can lead to a tough, dense crust. Handle it gently and keep it cold until you’re ready to bake.
• For a shortcut, use pre-made caramelised onions or roast the sweet potatoes a day in advance to save time during assembly and baking.

Storage Tips

• The tart can be made ahead of time up to the point of baking. Store it in the refrigerator overnight and bake it in the morning.
• Leftovers can be stored in an airtight container in the refrigerator for up to 2 days. Reheat in the oven until warmed through.
• Freezing is not recommended for this tart, as the pastry and filling can become soggy upon thawing.

Gift Packaging Ideas

If you’re considering gifting this tart, it presents beautifully when wrapped in a rustic paper or placed in a wooden crate, garnished with fresh herbs. For a more personal touch, include a handwritten recipe card or a small jar of caramelised onions for the recipient to use in their own creations.

Flavor Variations

• Spice it up by adding some red pepper flakes to the sweet potatoes for a spicy kick.
• Experiment with different types of cheese, such as goat cheese or parmesan, for unique flavor profiles.
• Add some chopped nuts or seeds, like pine nuts or sesame seeds, on top of the tart before baking for added texture and flavor.

Troubleshooting

• If the pastry becomes too brown, cover the edges with foil to prevent further browning.
• In case the filling is too wet, bake the tart for an additional 5-10 minutes to dry it out slightly.
• For a flaky pastry, ensure that it remains cold and handle it gently to prevent the butter from melting and the pastry from becoming tough.

FAQs

• Can I freeze it? – It’s not recommended to freeze the assembled tart, as the pastry can become soggy. However, you can freeze the roasted sweet potatoes and caramelised onions for up to 3 months and assemble the tart when you’re ready.
• Is it gluten-free? – This recipe uses puff pastry, which typically contains gluten. For a gluten-free version, consider using a gluten-free pastry dough.
• Can I double the recipe? – Yes, you can easily double the recipe to make a larger tart. Just ensure that you have enough puff pastry and baking sheets to accommodate the increased size.
