      If I remember my genetics from GCSE biology correctly, blue eyes are recessive genes, so you have to inherit two to have blue eyes. Therefore, each parent could be brown-eyed but also carry a single blue-eyed allele so that the child could inherit one from each parent.

      Caveat: I studied this in GCSE about 10 years ago, so I am very happy to be corrected on this front as I am not confident in my answer!
