A smooth butter chicken sauce is a rich tomato-dairy emulsion. First decide whether the sauce never came together or looked creamy and then released visible oil.
Symptom matcher
Which one looks most like yours?
Small visual differences can point to very different causes.
The dairy was boiled too hard
Cold cream hit a very hot sauce
The sauce was reduced too far
Too much free butter or fat accumulated
Acid and dairy were combined under harsh heat
Right now
Can it be saved?
Take the pan off strong heat and whisk gently. A spoonful of warm water or cream can sometimes help a mildly separated sauce, but severe curdling may not fully reverse.
Limit: A broken emulsion, overcooked protein or oxidized surface cannot always be fully restored; rescue may improve serving quality without returning the original texture or color.

Answer one question at a time. The result comes from the same reviewed diagnosis data below.
What changed first: thickness, smoothness, color or texture?
The dairy was boiled too hard
The sauce looked smooth, then released oil after vigorous bubbling.
Likely cause: The dairy was boiled too hardCold cream hit a very hot sauce
Curds or oily streaks appear as cream is poured.
Likely cause: Cold cream hit a very hot sauceThe sauce was reduced too far
The sauce becomes very thick before oil appears.
Likely cause: The sauce was reduced too farToo much free butter or fat accumulated
A shiny oil layer forms even though dairy is not visibly curdled.
Likely cause: Too much free butter or fat accumulatedDiagnosis
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 dairy was boiled too hard
The sauce looked smooth, then released oil after vigorous bubbling.
Check whether the sauce boiled after cream or yogurt entered.
Remove from heat and whisk gently.
Keep dairy finishes at a gentle simmer.
Cold cream hit a very hot sauce
Curds or oily streaks appear as cream is poured.
Compare cream temperature with sauce heat.
Take the pan off heat and whisk slowly.
Add cream gradually over lower heat.
The sauce was reduced too far
The sauce becomes very thick before oil appears.
Check reduction time after dairy addition.
Loosen with a small amount of warm water.
Stop reduction at a coating consistency.
Too much free butter or fat accumulated
A shiny oil layer forms even though dairy is not visibly curdled.
Compare butter/oil quantity with sauce volume.
Spoon off excess free fat and whisk.
Use measured fat rather than adding repeatedly.
Acid and dairy were combined under harsh heat
Grainy pale flecks appear in the tomato sauce.
Check heat and dairy timing.
Lower heat immediately.
Finish dairy gently after the tomato base has cooked.
Don't jump to conclusions
Common misdiagnoses
Kitchen science
What is actually happening?
Food Network butter-chicken methods use gentle simmering and dairy-rich finishing; one older Food Network method explicitly reheats cream without boiling.
Testing plan
What we plan to test
Planned tests are shown transparently and are never presented as completed results.
Butter Chicken controlled comparison
Changing one suspected heat, moisture or ratio variable should change the observed failure while the other conditions stay constant.
