I’m not loyal to a single cookware style. My collection includes stainless steel, cast iron, and nonstick pans, and I’m now exploring carbon steel. Each type of cookware has its quirks, and understanding these differences allows you to cook confidently in any kitchen, no matter the pan at hand. Stainless steel, for example, is often thought to be too sticky, and many people wouldn’t even consider frying an egg in one.
But the truth is, you can—and you should! Eggs fried in stainless steel develop beautifully crispy edges, and you can whip up a fluffy, cheesy scramble in seconds. The secret to cooking eggs (or searing a steak, or frying fish) in a stainless steel pan isn’t about the amount of fat you use. The key is getting the pan hot enough to prevent sticking.
Why It's Crucial to Preheat Your Pan
Stainless steel has a porous structure, and these tiny pores expand and contract when exposed to temperature changes. When you place cold food on a hot pan, the temperature contrast causes these pores to rapidly contract, effectively gripping your food.
The issue is further complicated by the fact that proteins, such as those found in raw meat and egg whites, bond to the metal of your pan. Eggs are particularly tricky because when they come out of the shell, they are in a liquid form, which can seep into those small pores, making the grip even stronger.
This may sound like a recipe for a sticky mess, but if you heat your pan to the correct temperature, it creates a barrier between your food and those troublesome pores—and that's all thanks to the Leidenfrost effect.
What exactly is the Leidenfrost effect?
The Leidenfrost effect happens when the temperature of a material is much higher than the boiling point of the liquid it encounters. This allows you to dip your wet fingers into molten lead without burning yourself and, more practically, lets you cook an egg in a stainless steel pan. The heat from the metal vaporizes the liquid, creating a layer of steam that forms a protective barrier between the metal and the food (or your fingers), preventing the liquid egg white from making direct contact with the pan and seeping into its pores.
The simplest way to check if your pan is hot enough to cook an egg is by adding a drop of water. If it sizzles and steams, the pan isn't hot enough yet, and the Leidenfrost effect hasn't taken place. But if the water drop forms a little ball that rolls around the pan, you're good to go. If it breaks up into several smaller balls, however, the pan is too hot. Allow it to cool down and try again. This test is often called 'the mercury ball test' because the behavior and appearance of the water droplet resemble that of mercury.
You need to add a touch of fat.
After passing the mercury ball test, you can add some fat to the pan. It doesn’t take much. Oil is the best option, as the heat required for the Leidenfrost effect will burn butter, but if you enjoy a fried egg with crisp, browned edges, butter can work—though it does require more attention.
The fat adds moisture but doesn't form balls that bounce around, instead creating an even, protective barrier between the food and the pan. This allows you to scramble or fry without worrying about sticking. (Fat also conducts heat well, which is extremely useful in cooking.)
Even cheesy scrambled eggs, which are prone to sticking, slide off a well-heated stainless steel pan with ease. Don't believe me? Just take a look at the pan I used to scramble these eggs.
Bringing it all together
You don’t need to fully grasp the Leidenfrost effect, or any science for that matter, to fry an egg in a stainless steel pan. All you need to do is follow these simple steps:
Heat your dry pan over medium-high heat, adding drops of water until one forms into a ball and skitters across the pan, like in the video above.
Add a small amount of oil, just enough to cover the bottom of the pan, and let it heat for about five seconds.
Crack your eggs into the pan and cook as usual, remembering that they'll cook much faster due to the high heat required for creating a (virtually) nonstick surface.
That’s all there is to it. You should now feel confident in your ability to fry eggs in one of the most intimidating pans out there. (And, just maybe, dare to dip your hand into molten lead.)
