Preheat your oven to 350°F (175°C).
In a bowl, mix together flour, baking soda, and salt.
In a separate bowl, cream the softened butter and granulated sugar until light and fluffy.
Add the egg and vanilla extract to the butter-sugar mixture and beat until combined.
Gradually incorporate the dry mixture into the wet ingredients, mixing until just combined.
Gently fold in the chopped strawberries, being careful not to over-mix.
Drop spoonfuls of dough onto a parchment-lined baking sheet, spacing them at least 2 inches apart.
Bake in the preheated oven for 10–12 minutes or until the edges are light golden brown.
Allow the cookies to cool on the baking sheet for 5 minutes before transferring to a wire rack.
Dust with powdered sugar before serving for an elegant finish.
