Add flour, sugar, olive oil, and salt. Mix by hand or with the dough hook on low speed for 1 minute. Once all of the ingredients are mixed, slowly knead for 7 minutes by hand or with your dough hook on low-medium speed. If your dough is too wet, add up to 1/4 cup more flour. After kneading, your dough should be smooth and elastic. Poke it with your finger – if it slowly bounces back, your dough is ready to rise. If not, keep kneading.
