360 grams warm water (about 100 degrees F) 1 1/2 cups
1 tablespoon sugar
2 ¼ teaspoons yeast
113 grams sourdough starter (discard or active) (½ cup)
2 teaspoons kosher salt
2 tablespoons olive oil for dough
480 grams bread flour (4 cups)
4 tablespoons olive oil for pan and topping
flaky sea salt for topping
- Add warm water to a large mixing bowl. Sprinkle over sugar and yeast and stir. Let sit for 5 minutes or until you see some foaming.
- Add sourdough starter, olive oil, and salt and stir to combine.Add flour and mix with a wooden spoon, dough whisk, or by hand until a shaggy dough forms with no flour visible.
- Cover and rest for 15 minutes before performing first set of stretch and folds (detailed instructions and photos are in blog post). Repeat this every 15 minutes for the next hour. So you will perform 4 total sets of stretch and folds.
- After last set of stretch and folds, cover dough and allow to rise at room temperature for 1 hour until doubled in size. Or cover and place in the refrigerator for up to 24 hours (see make ahead option in notes section below).
- Prepare pan while dough rises: generously oil a 9×13 baking dish with olive oil and line with a sheet of parchment paper so that the edges hang over the long sides of the pan. This will prevent sticking and help lift the focaccia out later. Use a metal pan for an extra crispy and browned bottom and sides. If you use a ceramic baking dish you will not get as much browning.
- After dough has doubled, transfer to prepared pan and press into an even layer that covers the pan. You can stretch the dough a bit to make it fit.
- Cover and allow the dough to rise again until doubled and very puffy. This will take 60-90 minutes.Preheat oven to 425 degrees F with a rack in the lower third during last 20 minutes of rising time. If you have a baking stone or steel this is a great time to use it.
- When dough has risen, drizzle with 3 tablespoons of olive oil (and any optional toppings). Press your fingertips into the dough making the signature focaccia dimples all over the dough. Press all the way down and through the dough so you feel the bottom of the pan.
- If you have not added any toppings, simply sprinkle with flaky sea salt after dimpling and bake in preheated oven for 25-35 minutes until golden brown and baked through. The internal temperature should be between 190 and 210 degrees F. If desired, tent loosely with foil or parchment after 15 minutes to prevent any toppings from becoming overly browned or burnt.
Make ahead and store in fridge:
- To make ahead, prepare dough through the stretch and folds then cover tightly and transfer to the refrigerator for up to 24 hours. This will rise a LOT!!! Make sure you have plenty room for expansion. When ready to bake, spread cold dough into prepared baking pan and allow to rise according to recipe instructions. Keep in mind the rising time will be longer since the dough is cold. I also used some dough to make a few sourdough dinner rolls – they were light and airy and quite lovely.
- Like all breads, focaccia is best eaten fresh the first day, but if you have leftovers, store them in an airtight container and warm before serving.
