Mix all the ingredients together in a large bowl. You can use a stand mixer or do it by hand. You might not need all of the flour. You want to add enough so that the dough isn't super sticky but still wet. Cover and let rise for 2 hours at room temperature until doubled. *If making later, move immediately to the fridge before rising and let rise slowly in the fridge for up to 3 days for a more developed flavor. If refrigerating dough, remove from the oven about 45 minutes before you want to bake your bread.
Place Dutch oven with the lid on in the oven and preheat oven to 450℉. Place the dough on a lightly floured surface. Starting with the top, pull the top part of the dough down to the bottom, rotate 90° and repeat about 5 more time or until the dough takes a round shape. Shape into a ball and place seam side down on parchment paper. Cover and let dough rest while the oven continues to preheat.
Before baking, take a knife and cut a 1/4 inch slit down the middle of the bread. Lift bread carefully using the parchment paper and place inside preheated Dutch oven. Bake with the lid on for 30 minutes. Remove the lid and bake for an additional 10-15 minutes or until desired color is reached. Remove from the Dutch oven and let cool on a wire rack. Let sit for 20 minutes before slicing. Serve with salted butter and jam if desired.
Notes
Can I Use All-Purpose Flour Instead of Bread Flour?
Yes! Bread flour creates a slightly chewier texture and extra structure but all-purpose flour still works. If you don't have a Dutch oven you can bake on a baking sheet. A Dutch oven creates steam which makes the bread get that crisp exterior.
