Jim Lahey’s no-knead crisp, airy overnight ciabatta takes just minutes to mix and bakes up the next day with an aroma that’s to die for! Makes two 10-inch loaves.
In a large bowl, combine flour, water, salt, and yeast. Mix with a spoon for about 30 seconds, just until no dry flour remains. The dough will be very wet and shaggy.
Cover the bowl with plastic wrap and let sit at room temperature (70–72°F) for 12–18 hours, until the surface is bubbly and the dough has more than doubled in size.
Prepare Work Surface (Day 2):
Generously flour your work surface. Scrape the dough out in one piece, being careful not to deflate it. Use a gentle touch.
Shape the Dough and Proof:
Lightly dust the dough with flour and rub a little oil on your hands. Gently nudge the dough into a rough 14-inch square. Fold in half horizontally, then fold in half again to make a ~7-inch square.
Place the folded dough onto a parchment-lined baking sheet (using a bench knife helps if you have one to transfer the dough). Cover with a floured towel or plastic wrap. Let rise in a warm, draft-free spot for 1 hour, or until almost doubled. If it springs back when gently poked, let it rise for an additional 15 minutes.
Preheat Oven:
About 30 minutes before baking, preheat the oven to 475°F (245°C). If using a Dutch oven, preheat it now. If using a pizza stone or steel, place it on the center rack.
See Steam Methods and prepare your steam method now. (See below for options.)
Final Shape and Bake:
Prepare two flour-dusted parchment sheets (about 8″x12″). Cut the dough in half and place each very gently and quickly onto the parchment sheets. Gently shape each piece into a long, flat loaf (about 10 inches). Shape to fit your baking vessel if using a Dutch oven.
Transfer one loaf to the preheated baking surface. Bake for 10 to 15 minutes, then remove the steam source or uncover the loaf and continue baking for a total of 25 to 35 minutes, or until it is golden brown. Bake the second loaf the same way if baking one at a time.
How to Bake with Steam
Wet Towels: Place a metal dish on the bottom rack. Pour boiling water over 2 rolled-up wet towels just before baking.
Ice Cubes: Place a metal pan on the bottom rack and toss in a few handfuls of ice right before baking (avoid oven glass).
Dutch Oven: Bake the dough inside a preheated Dutch oven with the lid on for the first 10–20 minutes, then remove the lid to finish.
