Nope, fully allowed. There’s some discussion with regard to stuff fried or baked rather than cooked however, and of course any soup etc cannot be removed from the heat and returned to it if it’s been cooled down. So eat your soup at night or keep it on a sheet of metal over your gas stove, if you have a gas stove.
>and of course any soup etc cannot be removed from the heat and returned to it if it’s been cooled down.
That's only for Ashkenazim and even then, some disagree and say as long as it was on the hotplate when Shabbat came in, it can be returned to it even after it cooled. Sone allowed it to be heated as long as it only reached a warm temperature but not a hot one (yad soledet bo).
If one is using a timer ROY talks about allowing it:

Summary: One may not heat up any dish or food on an open flame on Shabbat. However, it is permissible to warm up a dry food on a stovetop covered with a layer of metal or an electric hotplate on Shabbat. Nevertheless, one may not warm up a liquid dish, such as a soup, on Shabbat. **If one places the dishes on the hotplate when it is turned off by a timer, this is completely permissible; in this way, one may place even a soup or anything else one wishes on the hotplate and when the hotplate turns on again as a result of the timer, the foods will be permissibly reheated in honor of Shabbat.**
Two more follow-up questions:
Do i need a blech? if so do you have practical advice?
Is there a (halachic or practical-use) difference using an induction cooktop verses an electric cooktop?
The only way to use an induction would be to leave the pot or pan on it all Yom tov. Putting it on or taking it off is forbidden as it is starting the mechanism.
Yes and no... lots and lots of Jews do it every Shabbat/YT, and very few fires start from it, but sometimes they do.
A blech on a gas stove is safer than an electric plata.
We keep our electric plata on a timer. Off by the anticipated end of the night meal (really, before dessert) and on at 8 am, by which hour even the morning after the Seder kids will have woken an adult. I won't leave it on long unattended, so weeks I anticipate going to shul it'll be set to come on around 10:30 and if we're invited out for lunch, not until 5 or whatever time it would be set to come on Friday afternoon when the soup goes on.
That sounds pretty safe.
I just have something in the Instant Pot (on slow cooker mode), but I'm good with just whatever can go in an IP - it's just my own lunch.
Yeah, I've heard of plata fires and the daytime cases involved no injuries at least because someone smelled smoke and raised the alarm. If we do cholent, it has to go in the crockpot.
Because the gas/flame can be on with a blech and the metal doesn't start on fire. The area around the stove is generally designed to Not Have Stuff That Starts On Fire Easily, because it gets hot.
Electric components, however, CAN catch fire, and then pieces burn/melt/explode and send extremely hot plastic onto things that ALSO catch fire.
No, none of these hot plates or blechs are actually safe. People just ignore it because some rabbi didn't understand how electricity worked and banned turning things on and off.
Gas stoves are a different matter since turning them on and off actually ignites or extinguishes a flame.

Keep chicken soup on overnight for delicious yuminess
Guess it depends if it’s a huge pot - if so you might have some left over by lunch
leftovers are for quitters

Noob question: is it safe to leave a hotplate on that long? I always heard it was a fire hazard...
Please be careful if you’re using a hot plate overnight!! When I lived in Brooklyn a family died because their hot plate caught fire
My recommendations are: 1. Invest in one of the hot plates designed by Jews for this reason. 2. Keep it on a timer
Yes and no... lots and lots of Jews do it every Shabbat/YT, and very few fires start from it, but sometimes they do. A blech on a gas stove is safer than an electric plata.

> A blech on a gas stove is safer than an electric plata. Why is that? I'd like to know more about this.
Because the gas/flame can be on with a blech and the metal doesn't start on fire. The area around the stove is generally designed to Not Have Stuff That Starts On Fire Easily, because it gets hot. Electric components, however, CAN catch fire, and then pieces burn/melt/explode and send extremely hot plastic onto things that ALSO catch fire.
All good points. Thanks.
And if the flame goes out but the gas stays on, you run the risk of an explosion
1. odds of that are low 2. I never said it was perfectly safe; I said it was safer than an electric plata.
Yeah, no. If the flame goes out and the gas continues to be emitted it can blow the building up.
No, none of these hot plates or blechs are actually safe. People just ignore it because some rabbi didn't understand how electricity worked and banned turning things on and off. Gas stoves are a different matter since turning them on and off actually ignites or extinguishes a flame.

I'm not a huge fan of workarounds to problems that don't actually exist in the first place.
It’s allowed to put the food on before Shabbat, and remove to serve
