Once all the flour has been added in, knead the dough. If using a standing mixer, switch the attachment to the bread hook and knead for 5-10 minutes until elastic. If you are kneading by hand, knead on a lightly floured surface for 10-15 minutes or until the dough is elastic. The dough is done being kneaded once it can be stretched without easily tearing and is smooth and tacky. This dough will still be pretty sticky when it is fully kneaded, so make sure your hands are well-floured if kneading by hand.
After the dough is fully kneaded, add it to a well-oiled bowl for the first rise. I prefer to coat my bowl in olive oil, but any oil works here. The dough will be sticky so you may want to lightly oil your hands before grabbing the dough.
Then, cover the bowl with plastic wrap or a towel, place in a warm place, and let rise 1 hour or until doubled in size. I like to test my dough by "poking" it with a finger. If it doesn't bounce back and stays indented, it is ready. It is also important to not “overproof” the dough, so do not let the dough sit too long.
