Bananas Foster Tart with Pecan Butterscotch Puff Pastry Step-by-step instructions

Before you start

Before starting, ensure the puff pastry is thawed but still cold. Heat the oven to 400°F (200°C) and line a baking sheet with parchment paper. Prepare the butterscotch pastry cream and butterscotch sauce if making them from scratch, or have store-bought versions ready.

Slice the bananas on a thick diagonal bias and chop the toasted pecans. Grate the blonde chocolate into curls. Beat the egg for the egg wash. Have all ingredients within reach before assembling the tart.

Instructions

Prep and Assemble

1. 1Prepare the Pastry and Toppings
   Heat the oven to 400°F (200°C). Line a baking sheet with parchment paper. Roll out the puff pastry sheet on a lightly floured surface to a 10x14-inch rectangle. Transfer to the prepared baking sheet. Using a sharp knife, score a 1-inch border around the edges, being careful not to cut all the way through. Prick the inside of the pastry with a fork. Refrigerate while preparing the toppings.
   Look for The pastry is cold and holds its shape; the border is scored but not cut through.
   Tip Chilling the pastry before baking helps it puff evenly and hold its shape.
2. 2Slice Bananas and Chop Pecans
   Slice the bananas on a thick diagonal bias into 1/2-inch pieces. Chop the toasted pecans cleanly into small, even pieces. Grate the solid block of caramelized golden blonde chocolate on the box grater into a fresh pile of blonde chocolate curls. Set all aside.
   Look for Banana slices are thick and even; pecans are uniformly chopped; chocolate curls are light and fluffy.
   Tip Use ripe but firm bananas so they hold their shape during baking.

At the end of this phase, the puff pastry is rolled and scored, the bananas are sliced on a thick bias, the pecans are chopped, and the blonde chocolate is grated into curls. The butterscotch pastry cream is warm and spreadable. The egg wash is ready. The oven is preheated and the baking sheet is lined. Everything is in place for a quick assembly.

Bake to Golden

3. 3Assemble the Tart
   Spread the warm butterscotch pastry cream over the base of the pastry, staying inside the scored border. Shingle the sliced bananas and toasted pecans in neat rows over the cream. Brush the pastry border with the beaten egg.
   Look for The cream is spread evenly; bananas and pecans are arranged in tidy rows; the border is glossy with egg wash.
   Tip Keep the filling within the border so the edges puff up and form a crust.
4. 4Bake the Tart
   Bake the tart in the preheated oven for 20 to 25 minutes, until the pastry is golden brown and puffed and the filling is set. The internal temperature of the egg-based filling should reach 160°F (71°C) to ensure the eggs are cooked through.
   Look for The pastry is deep golden and crisp; the filling is set and slightly bubbling at the edges.

   Tip Rotate the baking sheet halfway through for even browning.

The tart emerges from the oven with a deep golden, puffed pastry border and a set filling. The aroma of butterscotch and toasted nuts fills the kitchen. The filling is no longer jiggly and the pastry is crisp to the touch. The internal temperature of the filling has reached 160°F (71°C), ensuring the eggs are fully cooked.

Finish and Serve

5. 5Finish and Serve
   Remove the tart from the oven. Immediately drizzle the bubbling amber butterscotch sauce over the top. Sprinkle with the grated blonde chocolate curls. Let cool for 5 minutes, then lift a warm flaky portion and serve.
   Look for The sauce sizzles as it hits the hot tart; chocolate curls soften slightly but remain visible.
   Tip Serve warm for the best texture contrast between crisp pastry and creamy filling.

The tart is immediately drizzled with bubbling butterscotch sauce, which sizzles as it hits the hot pastry. Blonde chocolate curls are sprinkled over the top, softening slightly from the heat.

After a brief rest, the tart is sliced into portions. Each piece shows distinct layers: crisp pastry, creamy filling, bananas, and pecans, all glistening with sauce.

Common mistakes

One common mistake is overfilling the tart with pastry cream, which can cause it to bubble over during baking. Keep the filling within the scored border and use a thin, even layer. Another mistake is underbaking the pastry, which results in a soggy bottom.

Bake until the pastry is deeply golden and crisp. Also, avoid using overripe bananas, as they can become mushy and release too much moisture. Finally, do not skip chilling the pastry before baking; this helps it hold its shape and rise evenly.

How to tell it’s done

The tart is done when the pastry is deep golden brown and puffed around the edges. The filling should be set and no longer jiggly in the center. To ensure the eggs in the filling are fully cooked, insert an instant-read thermometer into the center of the filling; it should read at least 160°F (71°C).

The butterscotch sauce should be bubbling hot when drizzled over the tart. Let the tart cool for 5 minutes before serving so the filling sets slightly and the pastry stays crisp.
