Heat the oven to 400°F. Place the pastry on a parchment-lined baking sheet and prick the center with a fork.

Beat the almond flour, sugar, butter, egg, and almond extract until smooth. Spread it over the pastry, leaving a 1-inch edge.

Arrange the pears in overlapping rows. Sprinkle with sliced almonds.

Bake for 25–30 minutes, until the pastry is puffed and golden. Cool for 10 minutes before slicing.
