Ingredients
1 sheet puff pastry, thawed
2 tbsp unsalted butter
2 medium onions, thinly sliced
4 oz pancetta, diced
3 medium apples, thinly sliced
6 oz Brie cheese, sliced
½ cup apple butter
2 tsp fresh thyme leaves
Flaky sea salt, to taste
1 egg, beaten
Let's Get Cooking!
1️⃣ Preheat the Oven
Heat your oven to 400°F. Line a baking sheet with parchment paper. Keep the puff pastry chilled until you're ready to assemble.
2️⃣ Caramelize the Onions
Melt butter in a large skillet over medium heat. Add the sliced onions and a pinch of salt. Cook for 25–30 minutes, stirring occasionally, until deeply golden, soft, and sweet.
3️⃣ Crisp the Pancetta
In the same skillet, cook the diced pancetta for 5–7 minutes until golden and crispy. Transfer to a paper towel-lined plate.
4️⃣ Prepare the Pastry
Lightly flour your work surface and roll the puff pastry into a 10-by-14-inch rectangle. Transfer to the baking sheet and score a 1-inch border around the edges without cutting through the dough.
5️⃣ Spread the Apple Butter
Spoon the apple butter evenly across the pastry, keeping it inside the scored border.
6️⃣ Layer the Apples & Brie
Arrange alternating slices of fresh apple and creamy Brie over the apple butter, overlapping slightly to create a beautiful layered pattern.
7️⃣ Add the Savory Goodness
Scatter the caramelized onions and crispy pancetta evenly over the tart. Finish with fresh thyme leaves and a light sprinkle of flaky sea salt.
8️⃣ Brush the Pastry
Fold the pastry edges slightly over the filling, pinching the corners to secure them. Brush the exposed pastry with the beaten egg for a golden, glossy finish.
9️⃣ Bake Until Golden
Bake for 25–30 minutes, rotating halfway through, until the pastry is puffed, flaky, and beautifully golden and the Brie has melted.
🔟 Slice & Serve
Let the tart rest for 5 minutes before slicing into squares or elegant strips. Serve warm while the Brie is still creamy and the pastry is perfectly crisp.
Entertaining Tip: Cut into smaller squares for a holiday cocktail party, or serve larger slices alongside a crisp arugula salad for an effortless autumn lunch.
