Sourdough Shaping Techniques: Boule and Batard

Shaping is the moment of truth in sourdough baking. Good shaping creates surface tension that holds the dough tall during oven spring. Mastering both the boule (round) and batard (oval) gives you versatility for any recipe.

Why Shaping Matters

Surface tension is the key concept in shaping. When the outer layer of dough is taut and smooth, it acts like a balloon that resists spreading. Without this tension, even perfectly fermented dough spreads flat in the oven.

Shaping is a two-step process: pre-shape and final shape. The pre-shape creates initial structure and lets the gluten relax. The final shape adds the tension that carries through to baking.

Pre-Shaping

Turn your fermented dough onto a lightly floured surface. Using a bench knife and one hand, gently push the dough away from you while tucking the bottom edge underneath. Rotate and repeat to form a rough round shape.

Let the pre-shaped dough rest uncovered for 15-30 minutes. During this bench rest, the gluten relaxes, making the final shape easier and more effective. The dough should spread slightly but hold a general round shape.

Shaping a Boule

Flip the rested dough smooth-side down. Fold the edges into the center like an envelope — top, bottom, left, right. Flip it seam-side down and use both hands to drag it toward you on an unfloured surface.

The friction between dough and counter creates surface tension. Rotate slightly with each drag until the surface is smooth and taut. Place seam-side up in a floured banneton for the cold proof.

Shaping a Batard

Flip the rested dough smooth-side down into a rectangle. Fold the top third down and the bottom third up, like a business letter. Seal the seam gently with your fingertips.

Roll the dough seam-side down and use both hands to gently taper the ends. The finished batard should be an even oval shape with visible surface tension. Place seam-side up in an oval banneton.
