Summary:
A complete protein is a protein source that "contains adequate proportions of the nine essential amino acids" that our body can not produce on its own.
Relatively low in protein, a single cup of couscous contains 6 grams of protein, or about 12% of recommended daily values. [1]
To get the adequate amount of protein with couscous alone, you will need 8.4 cups of couscous (1320 grams) for an average female, or 10.1 cups of couscous for males. [4] That's over 1480 calories, and a lot of couscous! Pairing couscous with a richer protein source is a good idea.

Proportionally, couscous does contain abundant amounts of 7 out of the nine essential amino acids. However, couscous is a little short on lysine and methionine.[1]
To have adequate amounts of all nine essential amino acids with couscous alone, you will have to eat 15 cups of couscous (2342 grams) for an average person. [2]
That's about 77% more couscous to compensate for the lack of lysine and methionine, compared to the protein requirement alone.
