Start by preheating your oven to 325°F. Line two large baking sheets with parchment paper and set them aside. Having everything ready before you start mixing keeps the process quick and stress-free.
In a medium bowl, whisk together the flour, baking soda, and salt. This makes sure the leavening and salt are evenly distributed throughout the dough. Set the bowl aside while you work on the wet ingredients.
In a large bowl, beat the butter with both sugars until light and fluffy, about three minutes. This step adds air into the dough, which helps give the cookies their soft, chewy texture. Scrape down the bowl as needed.
Beat in the vanilla extract, then add the eggs one at a time on low speed. Mixing them in separately helps everything blend smoothly instead of curdling. Scrape the bowl again so nothing gets left behind.
Add the flour mixture to the butter mixture on low speed, mixing just until combined. Overmixing at this stage can make the cookies tough instead of tender. Stop as soon as you no longer see streaks of flour.
Gently fold in the white chocolate chips and freeze-dried strawberries until they're evenly spread through the dough. Try not to crush the strawberry pieces too much while mixing. You want little bursts of color and flavor in every cookie.
Scoop about three tablespoons of dough per cookie and roll it into a ball. Place the dough on your prepared sheets with the side showing the most chips and strawberries facing up. Leave about two inches between each cookie for spreading.
Bake one sheet at a time for 12 to 13 minutes, until the edges turn golden but the centers still look soft. Every oven runs a little differently, so start checking around the 11-minute mark. Slightly underbaked centers mean a chewier cookie once cooled.
Let the cookies rest on the baking sheet for a few minutes, then transfer them to a wire rack to finish cooling. This keeps the bottoms from overbaking on the hot pan. Cool for at least 15 minutes before digging in for the best texture.
