Burnt Bottom

Baking

A burnt or overly dark bottom while the rest of the loaf is perfect is a common frustration. This usually relates to oven setup, baking vessel, or rack position rather than the dough itself.

Burnt Bottom in sourdough most often traces back to Burnt bottoms result from too much direct heat from below, often due to oven hot spots or baking vessel placement, a bake-stage problem you can usually correct mid-bake. This page lists 3 immediate interventions to try on the current batch plus 4 adjustments to stop it recurring. Fixes assume a 68-72°F kitchen and an active, ripe starter.

How do I fix burnt bottom right now?

Work through these reversible steps on the batch in front of you, in order. Each one targets a different failure mode, so the first match is usually the fix. Stop as soon as the dough responds and resume your normal process from there.

  • 1Move the loaf to a higher oven rack immediately
  • 2Place a baking sheet on the rack below to deflect heat
  • 3Reduce oven temperature by 25°F for remaining bake time

What are the detailed fixes for burnt bottom?

If the quick steps above did not resolve things, these deeper adjustments rework the mix, fermentation, or handling stage where burnt bottom usually originates. Each card explains what to change, the reason it works, and the baking stage it belongs to.

Double Pan Method

Easy

Use two pans to insulate the bottom.

  1. Stack two sheet pans together
  2. Place Dutch oven or bread on top
  3. The air gap insulates from direct heat
  4. Bake as normal

Rack Adjustment

Easy

Move bread higher in the oven.

  1. Position rack in middle or upper-middle position
  2. Preheat with rack in place
  3. Heat rises, so higher means less bottom heat
  4. Monitor browning and adjust

How do I prevent burnt bottom next time?

Prevention is easier than a mid-bake rescue. The tips below target the variables (starter timing, hydration, temperature, and handling) that most often set up burnt bottom, so you build the fix into your process instead of reacting to a dough that has already drifted.

  • Place bread on middle or upper-middle rack
  • Use a light-colored Dutch oven or add parchment underneath
  • Place a baking sheet on the rack below to deflect heat
  • Know your oven. Use an oven thermometer to identify hot spots.

Signs You’ve Fixed It

  • The bottom should be the same colour as the sides — dark brown but not black.
  • Scratch it gently with a fingernail. You get a pale scratch mark, not flaking black carbon.
