reheating leftover omelette on stove in pan without overdrying or making it too oily?
There is no way to reheat an omelette &amp; arrive back at 'a fresh omlette'.
You serve it just before it's completely cooked, so it arrives at the table correctly finished. Five minutes later hopefully it's been eaten, before it's past its best.
Anything after that is going to be rubbery.
Reheated is going to be rubbery++, no matter what you do.
To be perfectly honest, if you really want to reheat one, put it in the microwave for 30s to 1m. It's never going to get any better than that… &amp; it will add no oil.
Re-heatable 'omelette' might best be considered as 'Spanish tortilla', which is never meant to be light &amp; fluffy in the first place &amp; microwaves rather well. If you keep half for tomorrow, or buy one in a supermarket, ready-cooked, then the microwave is actually the best way to get it back to temperature. Re-heating in a pan is a) slow &amp; b) will over-cook the outside before the inside is to temperature.
