Copper pans are popular among cooks due to their excellent heating properties. Copper is a soft metal with high thermal conductivity, second only to diamonds. This means that copper pans can efficiently distribute heat across their surface, making them ideal for cooking. However, copper is a highly reactive metal, so it must be lined with a non-reactive metal like nickel, tin, or stainless steel to be food-safe. While copper pans are excellent for even heating and responsiveness, they may not be the best choice for high-temperature cooking methods such as searing. This is because the high reactivity of copper can lead to discolouration at high temperatures, and there is a risk of melting the tin lining if the temperature exceeds 450°F. Therefore, it is recommended to use half the heat or flame that you would use with a non-copper pan and avoid heating an empty copper pan.

What You'll Learn
Copper pans are highly conductive
Because of copper's high conductivity, you don't need to use high heat or preheat the pan before cooking. In fact, it's recommended to use only half the heat or flame you would use with a non-copper pan, as copper pans can easily burn food and melt their tin lining. For example, if you would normally cook eggs in a stainless steel skillet on medium-high heat, you should cook them on medium-low in a copper pan.
Copper pans are great for cooking techniques that require even heating and responsiveness, such as pan roasting, butter basting, and making pan sauces. They're also useful for cooking delicate foods like egg whites, as they can respond quickly to changes in temperature. However, copper pans may not be the best choice for high-heat cooking methods like searing, where cast iron or carbon steel pans are often preferred due to their higher heat capacity.
While copper pans are excellent heat conductors, it's important to note that they require special care. Copper is a reactive metal, so it must be lined with a non-reactive metal like nickel, tin, or stainless steel to be food-safe. Maintaining this lining is crucial, as it can be damaged by extremely acidic or salty foods, and high temperatures can cause the tin lining to melt.

Copper pans are reactive
Copper pans are highly reactive and are not food-safe on their own. Copper cookware must be lined with a non-reactive metal, such as nickel, tin, or stainless steel, to be safe for cooking. The lining must be maintained and kept intact, with no pitting or verdigris (blue copper patina).
Copper has a high thermal conductivity, surpassed only by diamonds. It is a soft metal and conducts heat very well. Because of its high conductivity, copper cookware is more responsive to changes in temperature than other materials. This means that you can generally use a lower heat setting than you would with a non-copper pan. For example, if you would normally cook eggs in a stainless steel pan over medium-high heat, you should cook them over medium-low heat in a copper pan. This is to prevent the food from burning and to avoid melting the soft metal lining, which has a melting point of around 450°F.
Copper pans should not be heated when empty, and they should not be used in ovens above 325°F, as the oven temperature may fluctuate above 325°F, risking the melting of the lining. Copper pans are also not suitable for extremely acidic or salty foods, as these will corrode the pan over time.
Despite the need for some extra care, copper pans are worth the investment for those who love to cook. They provide even heating, making them ideal for cooking techniques that require consistent heat, such as pan roasting and butter basting. They also produce good pan drippings that can be deglazed to make sauces, as the even heat distribution reduces the likelihood of scorching.

Copper pans are safe to cook with
However, copper is also highly reactive, so it must be lined with a non-reactive metal like nickel, tin, or stainless steel to be food-safe. When buying a used copper pan, always inspect the interior to ensure that this lining is intact and free of pitting or verdigris, a blue copper patina. Maintaining this lining is crucial in caring for your copper pan.
Additionally, copper pans should not be heated excessively. A good rule of thumb is to use half the heat or flame you would use on a non-copper pan. For example, if you cook eggs on medium-high in a stainless steel skillet, use medium-low for copper. This prevents the food from burning and the tin lining from melting, as tin has a melting point of around 450°F.
Copper pans are also not suitable for extremely acidic or salty foods, as long-term contact will corrode the pan. For example, tomato sauce should not be cooked in a copper pan as it will create an acid that will corrode the pan and render the sauce inedible.
Despite these considerations, copper pans are safe to cook with and offer excellent heating properties, especially if they are old and thick. They can be used to sauté and brown steaks, chops, and scallops, resulting in a nice brown crust. The evenness of heat and responsiveness of copper pans also make them ideal for pan roast and butter-basting techniques, as it is less likely to scorch the pan drippings.

Copper pans are high maintenance
Copper pans are also not suitable for oven use above 325°F due to temperature fluctuations in ovens. Additionally, copper pans should not be heated when empty. Copper is highly reactive, so it must be lined with a non-reactive metal like nickel, tin, or stainless steel to be food safe. Maintaining this lining is crucial in caring for a copper pan. The lining must be inspected before use, ensuring there is no pitting or verdigris (blue copper patina).
Copper pans also require special care when cleaning due to their reactivity. Acidic foods, such as tomatoes, can corrode the pan and render sauces inedible. Salty foods should also be avoided as long-term contact can cause corrosion. To clean a copper pan, it is recommended to use a special copper polish or a mild acid like lemon, vinegar, or tomato juice.
Despite the maintenance requirements, copper pans are a worthwhile investment for those who love to cook. They provide excellent heating properties, and their responsiveness makes it less likely that pan drippings will scorch.

Copper pans are expensive
Copper pans are some of the most expensive cookware available. This is because copper is a soft metal with extremely high thermal conductivity—it is the second-best conductor, with only diamonds being better. This means that copper pans offer excellent heating properties. In fact, copper is so conductive that people often have to learn what temperatures to cook different foods at.
Because of its high conductivity, copper cookware does not need to be preheated or cooked on high heat. In fact, it is recommended that you use half the heat or flame you would use on a non-copper pan, as copper pans are highly responsive to changes in temperature. For example, if you would cook eggs in a stainless steel skillet on medium-high, you should use medium-low heat for a copper pan. This is to prevent the food from burning and to avoid melting the tin lining, as tin melts at around 450°F.
Copper pans are also relatively low-maintenance, contrary to popular belief. The key is to understand the material and its weaknesses. For instance, copper pans should not be heated when empty, and they should not be used to cook extremely acidic or salty foods, as long-term contact will corrode the pan. Additionally, be sure to always inspect the interior of the pan to ensure that the lining is intact, with no pitting or verdigris (blue copper patina).
Despite the high cost and necessary care, copper pans are worth the investment for those who love to cook. They can be used to sauté and brown steaks, chops, and scallops, resulting in a nice brown crust. They are also excellent for making sauces, as the evenness of heat and responsiveness make it less likely that the pan drippings will scorch.
