Ingredients

For the Tart

• 1 sheet (about 250 g) puff pastry, thawed
• 1 medium sweet potato (about 300 g), peeled and thinly sliced
• 8 oz (225 g) Brie cheese, thinly sliced
• 1/3 cup (40 g) dried cranberries
• 1 large egg, beaten
• 1 tbsp olive oil
• 1/2 tsp dried thyme
• 1/2 tsp garlic powder
• 1/4 tsp salt
• 1/4 tsp black pepper

For the Caramelized Onion

• 2 medium yellow onions, thinly sliced
• 1 tbsp olive oil
• 1 tbsp butter
• 1 tsp brown sugar
• 1 tbsp balsamic vinegar
• 1/4 tsp salt

For the Hot Honey Finish

• 2 tbsp hot honey
• 1/2 tsp red pepper flakes, optional

For Garnishing

• 1 tbsp fresh thyme leaves
• 2 tbsp chopped pecans or walnuts, optional
• 1 tbsp fresh parsley, chopped

How to Make It

1. Preheat the Oven

Preheat your oven to 400°F (200°C). Line a large baking sheet with parchment paper and set it aside.

2. Prepare the Sweet Potato

Peel the sweet potato and slice it very thinly and evenly. Place the slices in a bowl and toss gently with olive oil, dried thyme, garlic powder, salt, and black pepper until evenly coated.

3. Caramelize the Onions

Heat the olive oil and butter in a large skillet over medium-low heat. Add the sliced onions and salt. Cook for 20–25 minutes, stirring occasionally, until the onions become very soft and deeply golden.

Stir in the brown sugar and balsamic vinegar and cook for another 2–3 minutes, allowing the onions to become glossy and richly caramelized. Remove from the heat.

4. Prepare the Puff Pastry

Carefully unfold the thawed puff pastry onto the prepared baking sheet. Using a sharp knife, lightly score a 1-inch border around the edges without cutting completely through the pastry. Prick the center several times with a fork to help prevent excessive puffing.

5. Add the Caramelized Onions

Spread the caramelized onions evenly over the center of the pastry, keeping the scored outer border clear. Try to distribute the onions in an even layer so every slice gets plenty of flavour.

6. Layer the Sweet Potato

Arrange the seasoned sweet potato slices over the caramelized onions. Slightly overlap the slices in neat rows or a simple pattern for an attractive presentation.

7. Add the Brie

Arrange the thin slices of Brie evenly over the sweet potatoes. As the tart bakes, the Brie will melt into the sweet potato and onion layers, creating a rich and creamy topping.

8. Add the Cranberries

Sprinkle the dried cranberries evenly over the Brie and sweet potato layers. Their sweet-tart flavour provides a lovely contrast to the creamy cheese and caramelized onions.

9. Brush the Pastry

Brush the exposed puff pastry border with the beaten egg. This helps the edges become beautifully golden and crisp as the tart bakes.

10. Bake

Bake for 25–30 minutes, or until the puff pastry is deeply golden and crisp, the sweet potato is tender, and the Brie is melted and bubbling.

11. Add the Hot Honey

Remove the tart from the oven and immediately drizzle the hot honey over the top while everything is still warm. Sprinkle with red pepper flakes if you want an extra touch of heat.

12. Garnish

Finish with fresh thyme leaves, chopped pecans or walnuts, and fresh parsley. The herbs add freshness while the nuts provide an optional crunchy contrast.

13. Rest and Serve

Let the tart rest for 5–10 minutes before slicing. Serve warm while the pastry is crisp, the Brie is creamy, and the sweet and savory toppings are beautifully caramelized.

Why This Recipe Works

This tart brings together several flavours that naturally complement one another. Sweet potato and caramelized onions provide gentle sweetness, while Brie adds a rich, buttery creaminess that melts beautifully over the top.

Dried cranberries introduce a bright sweet-tart note, while balsamic vinegar gives the onions extra depth. Finally, hot honey adds a glossy finish with just the right combination of sweetness and heat.

The flaky puff pastry ties everything together and gives the tart a crisp, golden base that contrasts beautifully with the soft toppings.

Tips for the Best Sweet Potato Puff Pastry Tart

• Slice the sweet potato thinly: Thin, even slices cook more quickly and evenly in the oven.
• Don’t rush the onions: Slow caramelization develops a deeper, sweeter flavour and prevents the onions from burning.
• Keep the pastry cold: If the puff pastry becomes very soft while you’re assembling the tart, chill it briefly before baking.
• Leave the border clear: Keeping the outer edge free of toppings helps it puff beautifully and become crisp.
• Use good-quality Brie: A creamy Brie melts smoothly and gives the tart its luxurious texture.
• Add the hot honey after baking: Drizzling it over the warm tart keeps its flavour bright and prevents it from becoming overly sticky or bitter.
• Let it rest briefly: A few minutes of resting makes the tart easier to slice while keeping the pastry crisp.

Serving Suggestions

This tart makes a beautiful appetizer for holiday gatherings, dinner parties, or casual entertaining. Cut it into small squares or rectangles and serve it as an elegant finger food.

For a light lunch or dinner, pair it with a simple green salad, roasted vegetables, or a fresh apple and arugula salad. It also works wonderfully alongside soup during the cooler months.

For an extra festive presentation, scatter additional cranberries, toasted nuts, and fresh thyme over the platter just before serving.

Frequently Asked Questions

Can I make this tart ahead of time?

Yes. You can caramelize the onions and prepare the sweet potato slices ahead of time. For the best texture, assemble and bake the tart shortly before serving.

Can I use another cheese instead of Brie?

Yes. Camembert is an excellent substitute for Brie. You can also use goat cheese for a tangier flavour, although the texture will be slightly different.

Can I use maple syrup instead of hot honey?

Yes. Maple syrup works beautifully with sweet potato, Brie, cranberries, and caramelized onions. For a spicy version, mix the maple syrup with a small pinch of red pepper flakes.

Can I use fresh cranberries?

Dried cranberries work best because they provide concentrated sweetness and a chewy texture. If using fresh cranberries, cook them briefly with a little honey or maple syrup first to soften their sharpness.

How do I keep the puff pastry crispy?

Avoid adding overly wet toppings, don’t overload the center of the pastry, and bake the tart until the pastry is deeply golden. Serving it soon after baking will also give you the best crisp texture.

Can I add nuts?

Absolutely. Toasted pecans or walnuts add a delicious crunch and pair especially well with the sweet potato, Brie, cranberries, and hot honey.
