Step 1

Cut a piece of parchment paper to fit an air fryer basket.

Step 2

Beat butter in a large bowl with an electric mixer on medium to high speed for 30 seconds. Add brown sugar, white sugar, baking soda, and salt; beat on medium speed for 2 minutes, scraping bowl occasionally. Beat in egg and vanilla extract until combined. Add flour, beating in as much as you can. Stir in any remaining flour, chocolate chips, and pecans.

Step 3

Drop dough by teaspoonfuls 1 inch apart onto the parchment paper. Carefully transfer the parchment paper to the air fryer basket.

Step 4

Turn the air fryer to 300 degrees F (150 degrees C) and cook until golden brown and set, about 8 minutes. Remove parchment paper to a wire rack to cool. Repeat with remaining cookie dough.
