Stainless Steel Pan Maintenance: Oil Or No Oil?

There are differing opinions on whether to heat a stainless steel pan before adding oil. Some people believe that adding oil to a hot pan is better as it prevents food from sticking, creates a non-stick layer, and allows the oil to heat up faster. Others argue that it doesn't matter whether the pan is heated before or after adding oil, as long as the pan is hot enough when the food is added. However, if you are cooking with high heat, it is generally recommended to heat the pan before adding oil to avoid burning the oil. Additionally, using an oil with a high smoke point, such as vegetable, canola, or grapeseed oil, is important to prevent smoking and potential fires.

Heating stainless steel pans before adding oil prevents food from sticking

Heating a stainless steel pan before adding oil is a widely recommended technique to prevent food from sticking. This is because the metal of the pan expands slightly when heated, closing any minuscule fissures, pores, or gaps in the surface of the pan. This creates a smoother, tighter, sleeker surface for the oil to slide on, and prevents food from getting stuck in those pores as they close when the pan heats up.

When oil is added to a cold pan, it takes longer to heat up and can become too hot, resulting in burnt or unevenly cooked food. Adding oil to a preheated pan, on the other hand, brings it up to the appropriate temperature faster. With a preheated pan, you will see the oil texture change before your eyes, and you can add your food almost immediately.

To heat a stainless steel pan before adding oil, place the pan on a burner over medium-high heat. Allow the pan to heat up for a few minutes until it is hot to the touch. You can test the heat of the pan by adding a few drops of water to the surface. If the water droplets sizzle and evaporate quickly, the pan is ready for the oil.

Once the pan is hot, add oil to the pan and swirl it around to coat the bottom and edges. Use an oil with a high smoke point, such as vegetable oil, canola oil, or grapeseed oil. Allow the oil to heat up for a few seconds before adding any food. You can test the heat of the oil by adding a small piece of food to the pan. If it sizzles and begins to cook immediately, the oil is hot enough.

By heating a stainless steel pan before adding oil, you can ensure your food cooks evenly, doesn't stick to the pan, and develops a nice sear.

Oil should be heated until shimmering, but not smoking

When cooking with a stainless steel pan, it is recommended to heat the pan before adding oil. This is because the metal of the pan expands slightly when heated, closing any minuscule fissures, pores, or gaps in the surface of the pan. This creates a smoother, tighter, sleeker surface for the oil to slide on, and prevents food from getting stuck in those pores as they close when the pan heats up.

When heating oil, it is important to heat it until shimmering, but not smoking. Shimmering oil has a temperature of about 275°F, while smoking oil is much hotter at around 400°F. If you are worried about burning the oil, relax. Oil that has just reached its smoke point is hard to miss. You will see multiple wisps rising from the pan. Shimmering oil can be hard to spot, especially in pans with a dark bottom, but you may notice the oil moving in a looser, more fluid manner. If you tilt the pan, shimmering oil will slide across the surface in one glistening layer.

Heating oil to shimmering is important because it is the optimal temperature for browning food. A test kitchen compared two steaks, one cooked in shimmering oil and one cooked in smoking oil. The steak cooked in smoking oil was done in half the time and browned more evenly, with less overcooked meat. However, it is important not to heat the oil above its smoke point, as this can cause the oil to break down, leading to flavour degradation and the release of toxic chemicals. It can also make the oil viscous and gummy, and more likely to stick to the pan.

Preheating a stainless steel pan helps create a non-stick layer

When it comes to cooking with stainless steel pans, a common question arises: should you heat the pan before adding oil? The answer is a resounding yes, and here's why.

Firstly, let's understand the science behind it. Stainless steel has a porous surface with minuscule fissures, pores, and gaps. When you preheat an empty stainless steel pan, the metal expands due to thermal expansion, causing those pores and gaps to close up. This results in a smoother, tighter, and sleeker surface.

Now, when you add oil to this preheated pan, it can slide freely on the closed pores, creating a non-stick layer. This not only prevents food from sticking but also makes cleanup a breeze. The oil acts as a lubricant, ensuring that your food glides effortlessly across the pan's surface.

To test if your pan is ready for oil, you can perform the water droplet test (also known as the mercury ball test or Leidenfrost effect). Simply add a teaspoon of water to the pan. If the water forms a large, marble-like drop that bounces off the sides, your pan is ready. This indicates that the temperature is ideal for adding oil and will help prevent food from sticking.

It's important to note that the temperature of the pan is crucial. If the pan is too cold, food is more likely to stick. On the other hand, if the pan is too hot, your food might burn and stick to the pan. Therefore, finding the right balance is essential.

Additionally, bringing your ingredients to room temperature before adding them to the pan is advisable. This ensures that the temperature of the pan doesn't drop too much, maintaining the non-stick barrier you've created.

In summary, preheating a stainless steel pan before adding oil is a crucial step in creating a non-stick surface. By understanding the science behind it and following simple techniques like the water droplet test, you can achieve better cooking results and make cleanup a breeze.

Stainless steel pans are ideal for searing meat

Firstly, stainless steel pans are non-reactive, meaning they can build pan sauces regardless of the acidity of the ingredients. This is not the case with cast iron, carbon steel, or aluminium pans.

Secondly, stainless steel pans are nearly indestructible. They are also oven-safe, which is critical for a piece of cookware that can go from stovetop to oven without issue.

Thirdly, stainless steel pans are highly responsive, which is important for rapid-fire cooking processes like sautéing or making pan sauces. They are also able to retain enough heat to effectively sear a piece of meat.

Finally, stainless steel pans are easy to clean. You can wash them with soap and a sponge, and they are even dishwasher-safe.

However, it is worth noting that cast iron pans are also good for searing meat. They retain heat better than stainless steel pans, which can make it easier to get a good sear on your steak. Cast iron pans are also oven-safe at any temperature, whereas stainless steel pans are generally safe only up to 500 degrees.

Stainless steel pans can be seasoned to create a semi-nonstick surface

To season a stainless steel pan, start by washing the pan with dish soap and warm water. Rinse the pan thoroughly and let it air dry. Next, choose an oil with a high smoke point, such as sesame, grapeseed, peanut, canola, avocado, sunflower seed, or soybean oil. Pour about 2 tablespoons (30 ml) of the oil into the pan, then swirl the pan around to evenly coat the bottom and sides. Heat the pan over medium heat on the stove for 2 to 5 minutes, or until the oil begins to smoke. As soon as you see any smoke rising from the pan, immediately move it off the burner and turn off the heat. Let the oil cool for at least 30 minutes, then pour it out of the pan or soak it up with a clean paper towel. Wipe the remaining oil out of the pan with a paper towel using circular motions.

To maintain the seasoning, always preheat the pan to medium heat for about 10 minutes before cooking. Avoid cooking on high heat, as this can cause the pan to lose its nonstick properties. It's also important to avoid overcrowding the pan with too many ingredients, as this can lead to unbalanced temperatures and sticking. When you're finished cooking, gently wipe the pan with a dry paper towel. If the pan becomes very soiled and greasy, it's okay to wash it with soap and water, but you'll need to reseason the pan afterward.
