Preheat the oven to 400F (200C) fan bake. Line a baking sheet with parchment paper.
Place the puff pastry on the lined baking tray. Score a 1/2 inch (1.5cm) border around the edges, without cutting all the way through, and prick the centre with a fork. Spread the cream cheese mixture inside the pastry border.
1 sheet puff pastry, 1/4 cup cream cheese
Toss the asparagus with olive oil, minced garlic, lemon zest, and season to taste with salt and black pepper. Arrange the asparagus over the cream cheese and add grated parmesan evenly on top.
1 bunch asparagus, 2 tsp olive oil, 1 garlic clove, 1 tsp lemon zest, salt and freshly cracked black pepper, 3 tsp grated Parmesan
Bake for approximately 20-25 minutes, until the pastry is golden, puffed and crisp and the asparagus is tender.
Flake the hot-smoked salmon over the warm tart. Finish with fresh arugula, extra lemon zest and cracked black pepper. Slice and serve warm or cold.
1/2 cup hot-smoked salmon, 1 handful fresh arugula
Notes
Use cold puff pastry: Keep the pastry chilled until you're ready to assemble the tart. Cold pastry puffs up better in the oven, creating light, flaky layers.Don't overload the tart: Spread the cream cheese in a thin, even layer and arrange the asparagus in a single layer to prevent a soggy pastry base.Add the salmon after baking: Hot-smoked salmon is already cooked, so adding it after baking keeps it moist and flaky.Make ahead: Puff pastry tarts are best freshly baked but you can prep the ingredients ahead of time.
