How to Unwarp a Pan? 3 Super Easy Steps To Fix A Warped Pan

Non-stick pan is considered an effective assistant in the kitchen. It can help you make delicious fries, stir-fries, or even cookies without burning. However, after a while, the pan will be easily warped, affecting the quality of the dish and the user’s health.

That’s why today, we are bringing you the ultimate guide on how to unwarp a pan. Let’s check it out

Why Your Pan Warp?

Why Your Pan Warp

Before go to the main part, you must know the reasons why your pan was warped. Well, there are most popular reasons:

1. Overheating

Most quality pans on the market or on Amazon are usually made of stainless steel or hard-anodized aluminum. These have a great advantage as they do not rust when used for a long time, thereby ensuring consumers’ health.

However, both aluminum and stainless steel pans have a drawback: they both have high thermal expansion. As the temperature rises, the molecules inside will move more chaotic, creating more gaps, thereby causing the object to expand slightly.

This is even more likely for frying pans that are frequently exposed to high temperatures of about 200 degrees for 15-20 minutes. Especially when you are a clumsy person and often burn food like deep-fry shrimp from the pan. This action causes the temperature to exceed the medium heat rating of the manufacturer.

Furthermore, block casting and the surrounding edges also make the pan more susceptible to warping due to the restriction.

2. Pan Is Too Thin

Normally, the manufacturer will cast the bottom of the pan very thick to avoid warping. The protective layer will cover the entire surface of the pan’s bottom and will help radiate heat more evenly. It will avoid heat concentrating on one place, which is the main reason that leads to thermal shock or heat difference.

However, cheap pans often have the opposite structure. This affects the distribution of heat as well as the radiation of heat. Since there is no protective layer, the pan’s surface is exposed to direct heat, making it more susceptible to warping.

The rapid temperature change can also deform your non-stick frying pans. For example, let’s say you are cooking at a very high temperature and then rinsing in cold water to cool hot pans down, this action will cause thermal shock and easily make your pan wraps.

Whether the type of non-stick pan you use is quality cookware or not, pay extra attention to how it will be used to preserve frying pans for a long time.

3. Aluminum Pan Is More Likely To Warp

Each material has a different density and specific volume. This is an unavoidable physical property of all materials. However, the manufacturers have calculated to minimize the deformation due to heat and limited only a small part.

The ability to expand under heat conditions of stainless steel is lower than hard-anodized aluminum. So when cooking with high heat (on a gas stove) or high heat (on infrared stoves, induction cookers), the thinner the aluminum layer, the faster it will expand, resulting in the frying pans’ bottoms still flat. At the same time, the basin is protruding and concave.

How To Unwarp A Pan?

This instruction below will show you step by step on how to fix a warped pan.

Step 1: Check The Condition Of Warped Pans

Check the condition of warped pans

When you notice that the pan has heat deformation, the first thing you need to do is check the warranty status. Many manufacturers will attach warranty programs such as 1 for 1 within 3 months, 6 months, 1 year, or free repair for a certain period when selling their products.

If you are one of these, then congratulations, you are indeed very lucky. All you need to do is bring the pan to the center where you bought it and enjoy a full or partial free renewal or repair offer.

However, if your bending frying pan is out of warranty or is not under warranty, you will have to continue to check the pan’s condition. If the new pan’s warping is only about 15% of the original, you can hopefully fix it yourself. But if it warps more or cracking, you will have to say goodbye to the old frying pans and get a new one for replacement.

Step 2: Treat The Warped Pans With Boiling Water

Treat the warped pans with boiling water

Using hot water is a brilliant step. The main reason is that, under the influence of the heat source, the active molecules inside will behave in chaos, making the chemical bonds less stable.

First, you need to get clean water poured about 2/3 compared to the pan mouth is okay, no need to fill. Then, put the pan on the stove, turn on medium-high heat to boil the pan’s water. Just boil it until you see a lot of steam evaporation. Normally, it will take you a few minutes.

The next step is to turn off the heat and pour the amount of water in the pan. It would be best if you were careful not to get water on your hands or body, which can cause burns or blistering.

When you pour the water, the pan is still hot, so wait for the pan to cool down, then use a tissue or a soft cloth to wipe off any remaining water in the pan.

You should be careful not to overheat the water as the non-stick coating will begin to damage at temperatures above 200 degrees C.

Keep in mind not to put anything in the water as insoluble crystals will impact soft metals. It can leave dark spots or permanent stains on the bottom of the cast iron pans or copper pans.

Step 3: Use A Piece Of Wood And A Hammer

Fix a pan with hammer

These two things can be found at any of your nearby local hardware stores or on Amazon. It would be best to prepare a piece of wood about 2 inches thick and equal to the pan’s diameter. It would be best to choose woods with a slightly decent quality; avoid using ice-cream sticks or super thin laminated wood as they won’t withstand the force.

The first job that needs to be done is to place the wooden stick in the middle of the pan’s bottom, where it will warp the most. This is why it is vital to measure the long wooden stick exactly the pan’s diameter because otherwise, it will slip out of position or not fit.

You hold the hammer with your dominant hand and proceed to hit the wooden bar. It would be best to place frying pans on a towel or a durable surface to avoid damaging the heat plate. Repeat several times until the bottom surface of the pan is flat. Applying force will help hot pans return to their normal state.

Continue to rotate the stick to the other direction and repeat the steps above until you feel satisfied. At this point, rinse the pan with warm water to prevent splashes of wood and wipe with a dry cloth. Now, you can use your pan to cook frozen lasagna.


There you go, all things you need to know on how to unwarp a pan. Easy and simple, yet so effective! We hope that you can repair your frying pans successfully after reading this article. Thank you for reading, and don’t forget to share this with your family and friends.
