Treat this as a top-versus-bottom heat problem, not simply an overall oven-temperature problem. Inspect whether the burn is even across the dough, concentrated where flour sits, or paired with a pale cheese and rim.
Symptom matcher
Which one looks most like yours?
Small visual differences can point to very different causes.
Check baking-surface temperature and conductivity.
Check rack position.
Check top heat.
Check the dough formula against the oven temperature.
Check loose flour or semolina under the pizza.

Can it be saved?
Sometimes, if the underside is dark but not yet bitterly burned.
Limit: Once the underside is deeply scorched, the bitter flavor cannot be removed.
Interactive check
Get to the first clue faster
Answer one question at a time. The result comes from the same reviewed diagnosis data below.
Is the whole underside scorching very quickly on a steel or stone?
Is the pizza baking very low in the oven?
Is the bottom done while the top remains pale?
Does the dough contain substantial sugar or oil for a very hot bake?
Reduce bottom heat
The baking surface is delivering heat too aggressively.
Likely cause: The baking steel, stone or oven floor is too hot for the styleRaise the pizza
A low rack can bias the bake toward the underside.
Likely cause: The pizza is too close to intense bottom heatIncrease safe top heat
The top needs to catch up with the bottom.
Likely cause: The top of the oven is not providing enough finishing heatMatch dough to oven temperature
A rich dough can brown too fast in extreme heat.
Likely cause: The dough contains enough sugar or oil to brown unusually quicklyRemove excess launch flour
If the formula is lean, charred loose flour is the remaining likely cause.
Likely cause: Excess bench flour or semolina is burning under the pizzaDiagnosis
Check the likely causes
Start at the top, but skip anything that clearly does not match your batch. Evidence labels describe the support for each cause, not a fake probability score.
The baking steel, stone or oven floor is too hot for the style
The underside blackens rapidly while the cheese and rim are still pale.
Check the surface temperature with an infrared thermometer if available and compare it with the oven's top heat.
Move to a less conductive surface, lower the surface temperature or shorten preheat for the next bake.
Match the baking surface and preheat to the pizza style and bake time.
The pizza is too close to intense bottom heat
The bottom scorches while the top remains undercolored, especially on a low rack.
Move the same setup one rack higher and compare top-to-bottom browning.
Raise the rack for the remaining bake if the pizza can be moved safely.
Position the stone or steel where top and bottom finish at similar rates.
The top of the oven is not providing enough finishing heat
The bottom browns normally but cheese and rim lag behind.
Compare a bake with stronger top heat or a broiler finish, following oven-safe recipe guidance.
Move the pizza higher or use the broiler only if the recipe and equipment allow it safely.
Preheat thoroughly and plan a setup that balances bottom conduction with top radiant heat.
The dough contains enough sugar or oil to brown unusually quickly
The underside darkens unusually fast even when the surface temperature is reasonable.
Compare the dough formula with a lean pizza dough designed for high heat.
Reduce heat rather than trying to finish the top over an already burning bottom.
Use a dough formula suited to the intended oven temperature.
Excess bench flour or semolina is burning under the pizza
Black bitter patches correspond to loose flour rather than evenly browned dough.
Brush excess flour from the peel and inspect the underside for burned granules.
Remove excess loose flour before the next launch and clean the baking surface between pies.
Use only enough launch flour or semolina to prevent sticking.
Don't jump to conclusions
Common misdiagnoses
Kitchen science
What is actually happening?
A steel or stone transfers heat by conduction directly into the crust, while the top cooks largely through hot air and radiant heat. When conduction outruns top heat, the bottom can scorch before cheese and rim finish.

What we plan to test
Planned tests are shown transparently and are never presented as completed results.
Pizza top-to-bottom heat balance
Changing surface conductivity or rack position should change how quickly the bottom browns relative to the top.

Food Network preheats a pizza stone thoroughly, then uses the stone for the bottom and the broiler for the top.

King Arthur advises moving pizza lower if the bottom needs more color or adjusting position when top and bottom do not finish together.

King Arthur explains that steel transfers heat faster than stone and recommends thoroughly preheating the baking surface while matching it to the desired crust.
