Map where the underdone pieces are. Buried pieces point to crowding; one pale side points to missing a flip; mixed doneness across different sizes points to thickness.
Symptom matcher
Which one looks most like yours?
Small visual differences can point to very different causes.
Check overlap and load depth
Check whether it was flipped or shaken
Compare thickness
Compare starting temperature
Check position and airflow
Right now
Can it be saved?
Remove finished pieces, redistribute the remaining food and continue in short intervals. Do not keep already-done pieces in the basket just to bring thicker pieces up to temperature.
Limit: Food that is already burned, severely overcooked or stripped of most of its coating cannot be fully restored.
Interactive check
Get to the first clue faster
Answer one question at a time. The result comes from the same reviewed diagnosis data below.
Are pieces stacked, touching heavily or more than one layer deep?
Reduce the load
Crowding is the first airflow problem to correct.
Likely cause: The basket is overcrowdedWas the food shaken, flipped or rearranged during cooking?
Turn or shake
Expose protected surfaces to the hot airflow.
Likely cause: The food was not shaken or turnedAre the pieces visibly different in thickness or starting temperature?
Standardize size
Unequal thickness produces unequal cooking time.
Likely cause: The pieces are different sizes or thicknessesCheck starting temperature
A colder center can lag behind similar pieces.
Likely cause: The food started at very different temperaturesDiagnosis
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 basket is overcrowded
Pieces touch or overlap and the hidden sides stay pale or underdone.
Compare the center of the pile with pieces near open airflow.
Remove enough food to restore space and continue in batches.
Cook in a single layer when practical or stay within the appliance loading guidance.
The food was not shaken or turned
The side facing the basket or another piece is paler or less cooked.
Turn a few pieces and compare the exposed and hidden sides.
Shake or turn the food, then continue in short intervals.
Schedule a halfway shake or flip for foods that tolerate handling.
The pieces are different sizes or thicknesses
Small pieces are browned or dry while large pieces remain pale or underdone.
Compare thickness between the earliest- and latest-finishing pieces.
Remove finished small pieces and continue thicker pieces separately.
Cut or portion food to a consistent thickness.
The food started at very different temperatures
Two similar pieces cook differently even though they are positioned similarly.
Check whether some pieces were frozen, refrigerator-cold or room-temperature.
Separate colder pieces and extend only their cooking time.
Start comparable pieces at similar temperatures when food-safety guidance permits.
Basket position or load created an airflow hotspot
One side of the basket consistently colors faster than the opposite side.
Rotate the basket load or swap positions halfway and see whether the pattern follows location.
Rearrange the food and continue briefly.
Rotate or rearrange the load during cooking if your appliance shows a repeatable hotspot.
Don't jump to conclusions
Common misdiagnoses
Kitchen science
What is actually happening?
Philips says shaking multi-layer food restores airflow around the pieces and improves evenness. Recipe methods also standardize thickness and use controlled flipping or timing.
Testing plan
What we plan to test
Planned tests are shown transparently and are never presented as completed results.
Test whether basket load causes uneven cooking
A shallower, less crowded load should cook more evenly than a stacked load.

Sources & methodology
Technical claims are tied to sources; each source shows how it was checked. Recipe-dependent details are treated as context, not universal rules.

Food Network emphasizes one-inch steak thickness, a room-temperature rest and controlled timing for even doneness.

Philips says shaking stacked food helps air circulate and produces a more even result.
