Whether you’re a beginner or a seasoned home baker, mastering the art of scoring sourdough bread transforms your loaves — both in appearance and in the quality of the bake.

What Is Scoring, and Why Does It Matter?

Scoring is the act of making deliberate cuts on the surface of your shaped sourdough dough just before it goes into the oven. It might look purely decorative, but scoring serves a critical baking function: it controls where and how your loaf expands during the oven spring.

Without scoring, pressure builds unevenly beneath the crust, causing the bread to burst in random, uncontrolled places. A well-placed score directs that energy, giving you a dramatic ear (the raised, crispy ridge along the cut), an open crumb, and that signature artisan look.

In short: scoring = better oven spring, better crust, better crumb, and a more beautiful loaf.

What You Need to Score Sourdough Bread

The Right Tool: A Bread Lame

The most important tool for scoring is a bread lame (pronounced lahm) — a handle designed to hold a razor-sharp blade at the ideal angle. Unlike a kitchen knife or scissors, a lame gives you:

Precision and control over cut depth and angle
A thin, sharp blade that glides through cold, sticky dough without dragging The ability to make curved or angled scores with ease

A quality lame makes an enormous difference. A dull or awkward blade drags, deflates your dough, and ruins the surface you’ve worked hours to develop. If you’re serious about sourdough, investing in a well-crafted lame is one of the best decisions you can make.

Tip: Look for a lame with a comfortable handle and a blade that can be angled — this gives you far more scoring flexibility than a straight blade.

Other Helpful Tools
A sharp chef’s knife or serrated knife — for simple straight scores in a pinch

A spray bottle — a light mist of water on the dough surface before scoring can help the blade glide

A cold, well-proofed loaf — scoring is much easier on dough that has been retarded overnight in the refrigerator

How to Score Sourdough: Step-by-Step

Step 1: Prepare Your Dough

Score your loaf immediately before baking — ideally straight from the refrigerator after an overnight cold proof. Cold dough is firmer and easier to score cleanly. Have your Dutch oven or baking vessel preheated in the oven at 500°F (260°C).

Step 2: Turn Out the Dough

Gently turn your proofed loaf out of the banneton onto a piece of parchment paper. Work quickly — you want to score and load it into the oven before it warms up and softens too much.

Step 3: Hold Your Lame at the Right Angle

This is where most beginners go wrong. The angle of your blade matters more than the pattern you choose.

For a single curved ear score (the classic artisan look): hold the lame at roughly a 30– 45° angle to the surface of the dough, almost parallel to it. This shallow angle is what creates the ear.

For decorative scoring patterns (leaves, wheat, geometric): hold the blade more perpendicular (90°) to the dough surface for cleaner, more vertical cuts.

Step 4: Make Confident, Swift Cuts

Hesitation is the enemy of a good score. Use one smooth, fluid motion per cut — don’t saw back and forth. Score to a depth of about 1⁄4 to 1⁄2 inch (6–12mm). Too shallow and the score closes up; too deep and you lose structure.

For a single score, make one long arc from the top third of the loaf to the bottom third, running slightly off-center.

Step 5: Load and Bake Immediately

Once scored, load the dough into your preheated Dutch oven as quickly as possible. Bake covered at 500°F for 20 minutes (steam phase), then uncover and reduce to 450°F for another 20–25 minutes until deeply golden brown.

Common Scoring Mistakes (and How to Fix Them)

The score closes up and disappears

Blade was too perpendicular, or the score was too shallow

Try a shallower angle and go slightly deeper

The dough deflates when you score

Dough may be over-proofed, or your blade dragged instead of gliding Use a sharper blade, work faster, and check your proofing time

No ear forms

The lame angle was too steep — flatten the blade angle more toward the dough surface

Also check that your dough has adequate surface tension from shaping

Dough sticks to the blade

Try a very light dusting of rice flour on the surface before scoring Cold dough is less sticky — score straight from the fridge

Tips for Beautiful Scoring Every Time

1. Practice on every loaf — even simple loaves. Consistency comes with repetition.

2. Use a fresh blade — replace razor blades often. A dull blade drags and tears.

3. Score in good lighting — you need to see the surface tension and shape clearly.

4. Refrigerate your shaped loaf — cold fermentation improves both flavor and scorability.

5. Watch your loaf bake — see how the scores open up and adjust your technique next time.

The Best Tool for Scoring Sourdough

If you’re ready to take your sourdough scoring to the next level, the tool you use matters. A beautifully crafted lame — one that feels good in your hand and holds the blade securely at the right angle — makes scoring easier, more consistent, and more enjoyable.
