In a medium bowl, whisk together the flour, baking soda, and salt. Set aside.
In a large bowl, beat the butter and both sugars until light and fluffy, about 3 minutes. Beat in the egg and vanilla.
Add the flour mixture in three batches, beating until just combined. Stir in the oats and ginger.
Drop the cookie dough by heaping tablespoons onto the prepared baking sheets, spacing them about 2 inches apart. Flatten each cookie slightly with the palm of your hand.
