What made my chicken and noodles spoil last night?  

Goodness,

I don't have a clue what could have happened in such a short time unless by accident there was something added that might have already been a bit on the bad side.

I too have left things out overnight but not in the summer. Is it hot already where you are ?

Sorry that happened to you,

You are in the habit of leaving food out? I think that is dangerous isn't it? And the fact that it smelled sour the next day shows that maybe you should have refrigerated it. I'd say to try to keep food like this in the fridge and not on the stove overnight..

Depending on what kind of noodles you had in your soup the yeast in the noodles may have reacted causing it to foam and sour. I know that once before when I cooked spagetti noodles and the kids don't eat all of them and fail to clean up before they went to bed that the noodles were foamy and stinking by morning.

Sometimes it is the climate,or the room temperature that causes the food to get spoiled.
This always happens with me during summer.
So,i always sees to have cook only with small amount of foods to avoid any left over during summer.
But,if,it is not avoided to have left over foods,i try to make sure to have it refrigerated,or else,surely it is spoiled the next morning.

Have a good day always

I hate it when that happens! I have left my soup on the stove or cabinet all night like that. Even if it doesn't visibly look spoiled I always throw it away anyway. You can't trust it after it reaches room temperature. I don't know what caused the yuck though!

giftsandbagscom,

It has to do with the humidity and the stirrings during serving.

The next time when you want to preserve the contents in the pot whether it be a pot of soup or noodles, without refrigeration, you may want to bring the contents to a bubbly boil and keep the lid a little ajar.

I can assure that the contents inside will not go bad and would be good for consumption.

If your left your food hot and covered until morning. It will make some out from the gas. Due to this gas it will make the food like that.

Hi, giftsandbagscom. I am sorry to hear about this. The only thing that I can think of is maybe your kitchen was very warm. I think the climate could have played a role in why your chicken and noodles has spoiled. This is the only logical explanation that I can think of With the pot not being in a cooler environment, your food spoiled.

a lot depends on what it is. poultry of any kind is dangerous to leave out of refrigerator after its cooled. even if you cant smell, (and i imagine this stunk) or taste it, its still sometimes spoiled if left warm to long. you are lucky you could see it was spoiled because if you'd eaten any it would be food poisoning, diahrea, vomiting, etc. many times ive heard that what people often think is a cold or virus, is actually brought on by poultry dinner not kept properly fresh. if you've ever noticed, the trash will stink up the whole kitchen if bones and such from poultry is left in over night.

It could honestly be anything. I find a lot of times its the chicken also the noddles will soak up anything which will cause it to dry out and spoil. Also, being hot weather can cause it to spoil faster. I wouldnt suggest eatting meat or chicken that has been sitting out over night either.
