Cream butter and sugar: In a large bowl, cream together the softened butter and granulated sugar until light and fluffy, about 2-3 minutes using an electric mixer.
Add salt: Stir in the salt.
Add flour: Gradually add the all-purpose flour to the butter and sugar mixture, mixing on low speed until just combined. Do not overmix.
Fold in strawberries: Gently fold in the chopped strawberries.
Chill the dough: Cover the dough and refrigerate for at least 1 hour, or preferably overnight. This chilling period is crucial for preventing spreading and making the dough easier to handle.
Preheat and prepare: Preheat oven to 350°F (175°C). Line baking sheets with parchment paper.
Shape the cookies: There are a few ways to shape the cookies:
Slice-and-bake: Roll the dough into a log about 2 inches in diameter. Wrap in plastic wrap and chill. Once chilled, slice the log into ¼-inch thick rounds.
Cut-out cookies: Roll out the chilled dough to about ¼-inch thickness on a lightly floured surface. Use cookie cutters to cut out desired shapes.
Drop cookies: Scoop rounded tablespoons of dough onto the prepared baking sheets.
Bake: Place the cookies on the prepared baking sheets, leaving about 1 inch between cookies. Bake for 15-20 minutes, or until the edges are lightly golden brown. Be careful not to overbake.
Cool: Let the cookies cool on the baking sheets for a few minutes before transferring them to a wire rack to cool completely.
