Easiest Focaccia Bread (Print Version)

# Ingredients:

01 - 4 cups (512 g) all-purpose or bread flour
02 - 2 teaspoons (10 g) kosher salt
03 - 2 teaspoons (8 g) instant yeast
04 - 2 cups (455 g) lukewarm water
05 - Butter for greasing
06 - 4 tablespoons olive oil, divided
07 - Flaky sea salt, such as Maldon
08 - 1 to 2 teaspoons whole rosemary leaves, optional

# Instructions:

01 - In a large bowl, whisk together the flour, salt, and instant yeast. Add the water. Using a rubber spatula, mix until the liquid is absorbed and the ingredients form a sticky dough ball. Lightly coat the surface of the dough with olive oil. Cover the bowl with a damp towel, cloth cover, or plastic wrap. Place in the refrigerator for at least 12 hours or up to three days.
02 - Line two 8- or 9-inch pie plates or a 9×13-inch pan with parchment paper or grease with butter. Coat the pans with 1 tablespoon of oil each or 2 tablespoons for a 9×13-inch pan.
03 - Using two forks, deflate the dough by pulling it toward the center from the sides of the bowl. Split the dough into two equal pieces or leave whole if using a 9×13-inch pan. Place the dough into the prepared pans. Roll the dough in the oil to coat and let it rest for 3 to 4 hours at room temperature.
04 - Set a rack in the middle of the oven and preheat to 425°F.
05 - If using rosemary, sprinkle it over the dough. Pour 1 tablespoon of oil over each round of dough (or 2 tablespoons for a 9×13-inch pan). Using your fingers, create deep dimples in the dough. Sprinkle with flaky sea salt.
06 - Transfer the pans to the oven and bake for 25 to 30 minutes, until the underside is golden and crisp. Transfer the focaccia to a cooling rack and cool for 10 minutes before cutting and serving.
07 - Once cooled completely, store in an airtight container at room temperature for up to 3 days, or freeze for up to 3 months. Reheat at 350°F for 15 minutes to refresh the crust.

# Notes:

01 - Cold, refrigerated dough results in more airy and pillowy focaccia.
02 - Use a digital scale for precise measurements of flour and water.
03 - If using active-dry yeast, dissolve it in lukewarm water for 15 minutes before adding.
