Mix the dough. In a large bowl, whisk flour, salt, and yeast.
Add 1 1/4 cups water and stir with a wooden spoon until a shaggy dough forms. If it’s too dry, add a tablespoon of water at a time. You’re aiming for a soft, slightly tacky dough that holds together.
Rest, then knead briefly. Let the dough sit for 10 minutes.
This short rest makes it easier to handle. Turn it onto a lightly floured surface and knead for 5–7 minutes until smooth and elastic. If it sticks, dust lightly with flour, but don’t overdo it.
First rise (bulk fermentation). Place the dough in a lightly oiled bowl.
Cover with a damp towel or plastic wrap. Let it rise at room temperature until doubled, about 60–90 minutes. Cooler kitchens may take 2 hours.
Optional flavor boost: cold rest. For deeper flavor, punch down gently, cover, and refrigerate for 8–12 hours or overnight.
If skipping this step, move to shaping.
Shape the loaf. Turn the dough onto a lightly floured surface. Gently press into a rectangle, then roll it up tightly like a jelly roll. Pinch the seam and tuck the ends under to form a bâtard (oval) or shape a longer baguette.
Keep handling gentle to preserve air bubbles.
Second rise. Place the shaped dough seam-side down on parchment or a floured cloth. Cover lightly and let rise until puffy, about 30–45 minutes at room temperature. The dough should spring back slowly when poked.
Preheat the oven. Set a baking stone or inverted sheet pan in the oven.
Place a metal pan on the bottom rack for steam. Preheat to 475°F (245°C) for at least 30 minutes to ensure everything is blazing hot.
Score the loaf. Right before baking, use a sharp knife or razor to make 3–4 diagonal slashes, about 1/4 inch deep. This lets the bread expand without tearing.
Steam and bake. Slide the loaf (on parchment) onto the hot stone or pan.
Carefully pour 1 cup of hot water into the lower pan or toss in a few ice cubes. Close the door fast to trap steam. Bake for 10 minutes with steam, then remove the steam pan, lower the oven to 450°F (230°C), and bake another 15–20 minutes until deeply golden.
Check for doneness. The crust should be a rich brown, and the loaf should sound hollow when tapped on the bottom.
Internal temperature should be around 205–210°F (96–99°C).
Cool completely. Place on a rack and let cool for at least 45 minutes. This sets the crumb and keeps it from getting gummy.
