Combine all the ingredients in a bowl and mix with a fork until just combined—it won't look pretty yet. Cover with plastic and sit for 30-60 minutes.
Knead the bread for about 30 seconds to a minute, until it’s more combined and smoother. Once complete, cover again and let sit another 30 minutes.
With lightly damp hands, pick up dough and lightly stretch (don't tear) and fold over itself, do this 4-6 times. Place back in bowl and cover. Let sit for 45-60 minutes.
Repeat these folds another 3-4 times, letting the dough rest between each folding round.
Take your banneton basket and flour it heavily so the dough doesn't stick.
Take your dough, and pull the edges into the middle, turning every time until you get all the way around, creating a round, smooth side with seams on the other. Once a nice ball has been formed, place it, seam side UP in your basket. Cover with plastic wrap and place in the refrigerator overnight.
Before baking, preheat oven and Dutch oven to 475 degrees. Once heated, wait another 20-30 minutes to fully heat the Dutch oven.
Carefully remove Dutch oven and lid and drizzle a little bit of olive oil on the bottom. Over the sink, with a lightly damp hand, flip the dough into one hand, carefully place your dough seam-side down into the Dutch oven. Using a razor or serrated knife, cut 3/4-inch deep slashes to release air, 3-4 will work.
Place top back on the Dutch oven and put the whole thing in the oven for 20 minutes.
Remove top and let cook another 10-15 minutes until golden brown on top. If your oven is not super hot, you may need a few more minutes.
Remove from oven and carefully remove loaf from the Dutch oven and place on a cooling rack.
Once completely cooled, slice and enjoy!
