✔ Updated · 9 fixes for loaf pans, Dutch ovens and stones
When bread burns on the bottom, the base is simply getting more heat than the rest of the loaf.
Bread burns on the bottom when the base gets too much direct heat. The usual causes are baking on a low rack close to the heating element, an oven running hotter than the dial, dark or thin bakeware, or a very hot Dutch oven or stone. Move the bread to the middle rack, slide a baking sheet underneath, and check your oven with a thermometer.
- Rack: middle, not bottom
- Shield: an empty sheet pan on the rack below
- Oven: check it with a thermometer
- Pans: drop 25°F for dark metal or glass
Usually that means the rack is too low, the oven runs hot or the pan is dark, and every one of those is easy to fix.
9 Ways to Stop Bread Burning on the Bottom
Try these roughly in order. The first two fix most burnt bottoms on their own.
1. Move the rack up
The bottom element blasts heat at the lowest rack. Bake loaves on the middle rack, or one notch above, so the bottom isn't sitting close to the heat.
2. Slide a sheet pan underneath
Put an empty baking sheet on the rack below your loaf pan or Dutch oven. It shields the bottom from direct heat. This is my go-to fix.
3. Check your oven temperature
Many ovens run 25°F hot or more. A cheap oven thermometer tells you the truth; lower the dial to match.
4. Use lighter bakeware
Dark and glass pans absorb more heat and brown faster. With dark metal, drop the temperature about 25°F.
5. Dutch oven? Double up
Cast iron holds a lot of heat. Set it on a sheet pan or baking stone, or drop the heat 25°F once you remove the lid.
6. Use parchment or cornmeal
A sheet of parchment or a dusting of cornmeal under a free-form loaf adds a thin buffer. A folded double sheet of parchment helps more.
7. Watch sugar and milk
Enriched doughs (milk, sugar, honey, eggs) brown much faster. Bake them 25°F lower and tent with foil if the top darkens.
8. Don't over-preheat a stone
A stone or steel left in a very hot oven for an hour can scorch the base. 30 to 45 minutes is plenty for most loaves.
9. Finish on the rack
If the bottom is browning early, move the loaf out of the pan and straight onto the oven rack for the last 5 to 10 minutes.
Find the Cause Fast
| What you see | Likely cause | Try this |
|---|---|---|
| Bottom burnt, top pale | Rack too low or bottom-heavy oven | Middle rack plus a sheet pan below |
| Bottom and top both too dark | Oven runs hot | Oven thermometer; lower the dial |
| Burnt base in a Dutch oven | Cast iron holds too much heat | Sheet pan or stone underneath; lower heat after lid off |
| Only sweet or enriched loaves burn | Sugar and milk brown fast | Bake 25°F lower; tent with foil |
| Burnt base on a stone or steel | Surface overheated | Shorter preheat or parchment under the loaf |
Sourdough Burning on the Bottom in a Dutch Oven
This is the most common version of the problem I hear about. A Dutch oven preheated at 475°F to 500°F stores a huge amount of heat, and the loaf sits right on it.
What works for me: set the Dutch oven on a baking sheet, put a small square of parchment or a light scattering of cornmeal under the loaf, and drop the oven to 450°F when the lid comes off. If your base is still too dark, bake the last 10 minutes with the loaf out of the pot, straight on the rack. More sourdough help: why sourdough won't hold its shape and why sourdough isn't rising.
Can You Save a Loaf With a Burnt Bottom?
Usually, yes. Let the bread cool completely, then use a serrated knife or a fine grater to shave off the blackened layer. The inside is normally fine. Very dark, bitter crust is best cut away rather than eaten.
If you're still learning your oven, try a forgiving loaf like my easy homemade artisan bread. And if your loaves have other quirks, see what causes large holes in bread or why bread tastes yeasty.
Frequently Asked Questions
Why is the bottom of my bread burnt but the top is fine?
The base is getting more direct heat than the top, usually because the loaf is on a low rack close to the bottom element. Move it to the middle rack and slide an empty baking sheet onto the rack below to shield it.
Is burnt bread safe to eat?
A little dark crust is fine. Heavily blackened bread tastes bitter, and the FDA suggests toasting and baking to a golden color rather than dark brown to limit acrylamide. Cut or grate off charred parts and enjoy the rest.
Does a glass loaf pan make bread burn?
Glass and dark metal pans both absorb heat well, so the bottom and sides brown faster. Lower the oven temperature by about 25°F and check the loaf 10 minutes early.
Should I put bread on the top or bottom rack?
Most loaves bake best on the middle rack. Use the lower-middle rack only if the top browns too fast and the base stays pale, and avoid the very bottom rack.
How long should I preheat my oven for bread?
Preheat until the oven reaches temperature, then give it 10 to 15 minutes more so the walls are hot. With a baking stone or Dutch oven, 30 to 45 minutes is usually enough.
