Do not preheat an empty pan. Nonstick cookware is usually made of aluminum, which heats faster than heavier, denser stainless steel. Add a little bit of oil to the pan first (enough to lightly coat the surface), and preheat it for a few seconds before adding the food.
If you're using a bare metal (cast iron, stainless, carbon steel) and you're frying something (steak, rice or whatever) you heat the pan first then add a high temp oil to create a polymer layer. If you're using enamel or non-stick or you're just blooming spices for a curry or something then oil in before heating.
Low heat, don't preheat while it's empty e.g. add oil before preheating, no metal utensils, and only use it for things that actually require nonstick e.g. eggs. If you plan on things like searing steak your pans will degrade much faster. And they will degrade no matter what you do.
Yes, it's generally a good practice to let a pan heat up before adding oil. Here's why: Improved Cooking: Heating the pan first helps to create a non-stick surface, especially with stainless steel pans. When the pan is hot, the oil spreads out and forms a barrier between the food and the pan.
The simple act of preheating your skillet properly will stop your food from sticking the majority of the time. When a pan is properly preheated, the moisture in the food wicks away from the surface of the pan, and the fat that you add to the pan makes a slip and slide for your food on top of that hot pan.

You should add oil to a hot pan if you are using unseasoned cookware such as stainless steel. The reason why is that the high temperature of the pan will reduce the viscosity of the oil and allow it to settle into the small little cracks and pores in the pan.
Greasing the pan is a necessary step even when using a nonstick pan. Whether you're using a bundt pan, cake pan, cupcake pan, or cookie sheet, applying a thin layer of grease to the sides and bottom of the pan will help your baked goods release with ease.
Perhaps the simplest reason that some non stick pans start to stick, especially if the pan isn't very old, is that there's a layer of stuck-on food residue getting in the way. Even the thinnest layer of dried egg white or residual starch from stir-frying potstickers can cause food to stick.
Before using your non-stick pan for the first time, wash it with warm, soapy water to remove any dust or residues from the manufacturing process. Rinse thoroughly and dry with a soft cloth or paper towel. Some non-stick pans benefit from an initial seasoning.
Properly preheating the pan will prevent your food from sticking, at least most of the time. When a pan is properly preheated, the moisture in the food is drawn away from the surface of the pan and the fat you add to the pan for your food does its job.
Overheating is the big destroyer of non-sticks.
A certain minimum mass (i.e. thickness of metal) Ability of the metal to transmit heat fast around the pan (e.g. Copper or Aluminium both fast conductors of heat)
TIP: It's best to make sure there is a little bit of oil or fat in the pan before turning the hob on. Allow this to move around in the pan when warming the pan, then add your food. The idea is to support the non-stick coating by adding a layer of fat.
Some cooks recommend heating the pan before putting oil in. Others put the oil into a cold pan and heat both together. Either way, you want to get both nice and hot before food goes in. If the oil isn't hot enough, the food will soak it up instead of sizzling in it, and it won't taste as good.
When using non stick cookware, always preheat the pan with oil or another fat in it, or the non stick coating can be damaged. We advise skipping cooking spray, as it will burn a residue onto the pan. And, adding fat to the cold pan before heating strengthens the non stick properties of the pan.
Wash and dry it thoroughly first (remember not to use an abrasive scourer or cleaner), and make sure that the surface is well coated with fat or oil when you cook in it the first time. Never use a non-stick pan on full heat - overheating it will almost certainly damage the coating.
The first step: Always wait for the pan to cool before letting it come into contact with cold water. Submerging a hot pan in cold water or even running cool water over hot nonstick cookware is the quickest way to warp a pan. Also, the faster you get to hand-washing, the easier it will be.
She explained that seasoning these pans, both when you purchase a new one and whenever the coating seems to fade, helps maintain a surface that fried eggs and other easy-to-stick foods will slide right off of. Plus, by maintaining a nonstick surface, you're preventing food from burning and residue from building up.
