The moment you dump it out and your heart breaks
You waited 24 hours. You did the folds. You felt smug. Then you tipped the dough out of the banneton and watched it… slowly melt. Like a sad pancake with dreams.
Sourdough spreading instead of rising is one of the most common frustrations for home bakers, and it’s almost always caused by one of three things: weak gluten, over-fermentation, or sloppy shaping. Often a combination. Let’s diagnose what’s happening and fix it — for today’s loaf if we can, and definitely for your next one.
What “spreading” actually means
Quick vocab check. “Spreading” is when your dough loses its dome and flattens outward instead of rising up in the oven. Symptoms:
- Dough that can’t hold a ball shape after shaping
- Score lines that close up or disappear
- Loaves that bake wide and short instead of tall and round
- Crumb that might taste fine but looks dense and squat
If your dough also has huge bubbles and a sticky, almost slimy top, you’re probably overproofed. If it just feels slack and weak, it’s more likely a gluten or shaping issue.

Cause #1: Overproofed dough (the most common culprit)
If your dough looks beautiful in the banneton and then pancakes the second it hits the counter, you almost certainly overproofed. When fermentation goes too long, the acids produced by the bacteria literally eat through the gluten network you worked so hard to build. By the time you bake, there’s no structure left to hold anything up.
How to fix it:
- Aim for a 50–75% rise during bulk fermentation, not a full double
- Your dough should feel airy and jiggly (like Jell-O), domed on top, with visible bubbles along the sides
- In a warm kitchen (78°F+), check dough 1–2 hours earlier than the recipe suggests
- Use an aliquot jar or bulk proofing container with clear walls so you can actually measure rise
If you’re already in the spreading mess, bake anyway — it won’t be pretty, but it’ll taste fine as toast or croutons.

Cause #2: Weak gluten development
Gluten is what gives dough the strength to trap gas and rise upward. If your gluten network is underdeveloped, gas just escapes out the sides and your loaf collapses outward.
Most beginners underdo this step. You do two lazy stretch-and-folds, the dough looks “kind of” smooth, and you move on. It’s not enough.
How to fix it:
- Do 4 sets of stretch-and-folds in the first 2 hours of bulk fermentation, 30 minutes apart
- Each set: grab one side, stretch it firmly upward, fold over. Rotate bowl 90°. Repeat 4 times.
- By the 4th set, dough should feel tight, springy, and pass the windowpane test
- If using low-protein flour (9–11%), switch to bread flour (12%+) for more gluten
You should feel the dough get noticeably stronger with each fold. If it still feels slack after 4 sets, add a 5th.

Cause #3: Hydration too high for your flour
If you’re baking at 80% hydration with grocery-store all-purpose flour, your dough cannot physically hold its shape. Higher hydration needs higher-protein flour to compensate. Period.
How to fix it:
- Start at 70–72% hydration while you’re learning
- Only push higher once you’re using 12%+ protein bread flour
- If your dough feels like pudding after mixing, drop water by 30–40g next time
- Whole wheat and rye absorb more water than white — adjust accordingly
Higher hydration makes more open crumb, yes. It also makes spreading loaves if your technique isn’t there yet. Keep it simple while you learn.

Cause #4: Weak shaping (no surface tension)
Shaping is where you build the “skin” that holds your loaf together in the oven. If your skin is loose, your loaf spreads. Simple.
How to fix it:
- Pre-shape first: gently form a loose ball, let it rest 20–30 minutes
- Final shape on an unfloured surface (friction = tension)
- Drag the dough toward you with a bench scraper to build tension
- The surface should feel tight and smooth, like a drum
- Flip seam-side up into a banneton and pinch the seam closed
The dough should look like a taut, round ball after shaping — not a sad sack.

Cause #5: Starter wasn’t ready
A weak starter gives you weak dough. If your starter hadn’t peaked (or was already past peak and falling) when you mixed, fermentation will be slow and uneven — which often means by the time the dough “looks ready,” the gluten is already breaking down.
How to fix it:
- Use starter within 1–2 hours of peak
- Starter should double reliably in 4–8 hours at 75°F
- Do the float test: a spoonful in water should float
- If starter is sluggish, strengthen it before baking

Cause #6: No cold retard (and shallow scoring)
Shaping a dough and baking it right away, at room temp, is a recipe for spreading. The dough is warm, soft, and relaxed — exactly what you don’t want going into a hot oven.
How to fix it:
- Cold retard in the fridge for 8–16 hours after shaping
- Cold dough holds its shape far better when it hits the Dutch oven
- Score at a 30–45° angle, firm and confident — shallow scores force the dough to expand sideways
- One deep score beats three shy ones

Your pre-bake checklist
Before you put the loaf in the oven, verify:
- ✅ Starter doubled within 4–8 hours of feeding
- ✅ Dough rose 50–75% in bulk (not a full double)
- ✅ At least 4 sets of stretch-and-folds completed
- ✅ Dough passes the poke test (springs back slowly, about halfway)
- ✅ Shaped with visible surface tension
- ✅ Cold retarded in the fridge at least 8 hours
- ✅ Scored deeply at an angle
If you can check all seven, you should get a loaf that rises up, not out.
FAQs
Can I save sourdough that’s already spread? Kind of. You can’t un-spread it, but you can bake it anyway — the crumb will be denser and flatter, but still edible. Great for toast, grilled cheese, or croutons. Next time, shorten bulk fermentation.
Why does my dough spread only after cold retard? Usually means it was already overproofed before you put it in the fridge. Cold retard slows fermentation but can’t reverse it. Shorten your bulk time.
Is spreading a starter problem or a dough problem? Both are possible. A weak starter makes weak dough. But assuming your starter is strong, spreading is almost always over-fermentation or under-developed gluten.
Should my dough rise after shaping on the counter? A little — maybe 20–30%. If it’s ballooning, you’re heading for overproof territory. Get it in the fridge.
