What Not to Cook in Stainless Steel: Avoid These Foods for Better Maintenance

Avoid cooking acidic foods, delicate fish, and sticky recipes in stainless steel to prevent damage and sticking. Stainless steel cookware is unsuitable for cooking highly acidic foods like tomato sauce or lemon-based dishes due to potential reactions that can leach metals into the food.

Delicate fish also stick to stainless steel pans and can be difficult to flip without breaking. Additionally, sticky recipes like caramel or melted sugar can be challenging to clean from stainless steel surfaces. To prevent these issues, consider using alternative cookware, such as non-stick pans, for these dishes.



Acidic And Highly Alkaline Foods: Stay Clear Of These

When cooking with stainless steel, you must be mindful of the types of foods you choose. While stainless steel is generally a durable and versatile choice for cookware, it may not be the best option for certain acidic or highly alkaline foods.

Let’s delve into the impact of acidic foods on stainless steel cookware:

  • Acidic foods, such as tomatoes, citrus fruits, and vinegar, can react with the metal surface of stainless steel cookware. This interaction can cause the release of small amounts of metal ions into the food, altering its taste and appearance.
  • A high level of acidity can also lead to pitting or discoloration of the stainless steel surface over time. This can result in a less appealing appearance and even make cleaning more challenging.
  • It’s important to note that the extent of the reaction between acidic foods and stainless steel will vary depending on cooking time, temperature, and the quality of the cookware. However, as a general rule, avoiding prolonged cooking of highly acidic foods in stainless steel pots and pans is best.

Why Highly Alkaline Foods Can Cause Damage To Stainless Steel

While acidic foods can challenge stainless steel cookware, highly alkaline foods can also cause damage. Here’s why:

  • Highly alkaline foods, like baking soda, can cause a process called alkaline attack on stainless steel. This reaction occurs when the alkaline substances come into contact with the metal, breaking the protective layer on the cookware’s surface.
  • The breakdown of the protective layer can lead to corrosion, staining, and even the formation of pits on the stainless steel surface. This affects not only the appearance of the cookware but also its overall durability.
  • It’s worth noting that the severity of the alkaline attack will depend on factors such as the concentration of the alkaline substance and the duration of exposure. However, to maintain the longevity of your stainless steel cookware, it’s generally advisable to avoid cooking highly alkaline foods in them.

Examples Of Foods To Avoid Cooking In Stainless Steel Due To Their Acidity Or Alkalinity

When using stainless steel cookware, it’s recommended to steer clear of certain foods that are either highly acidic or alkaline. Here are some examples:

Acidic foods to avoid:

  • Tomatoes: The high acidity in tomatoes can cause discoloration and alter food taste when cooked for an extended period in stainless steel cookware.
  • Citrus fruits: Lemons, oranges, and other citrus fruits contain acids that can react with stainless steel, potentially affecting the quality of the cooked food.
  • Vinegar: Whether it’s white vinegar or apple cider vinegar, the acidic properties of vinegar can cause the release of metal ions and compromise the appearance of stainless steel cookware.

Highly alkaline foods to avoid:

  • Baking soda: This staple ingredient in baking can cause an alkaline attack on stainless steel cookware, leading to corrosion and potential damage.
  • Lye: Used in the making of traditional pretzels and some Asian dishes like century eggs, lye is highly alkaline and not suitable for cooking in stainless steel cookware.

By being cautious and avoiding prolonged cooking of highly acidic or alkaline foods, you can help preserve the quality and appearance of your stainless steel cookware. Consider using alternative cookware materials better suited for these foods, such as cast iron or enamel-coated pots and pans.

Foods With High Salt Content: A Recipe For Corrosion

While stainless steel cookware is versatile and durable, avoiding cooking foods with high salt content is crucial. By being mindful of the salt levels in the dishes you prepare, you can ensure the longevity and aesthetics of your stainless steel cookware.

How High Salt Content In Certain Foods Can Lead To Corrosion In Stainless Steel

Stainless steel is a popular choice for cookware due to its durability and resistance to rust. However, certain foods can cause corrosion in stainless steel, especially those with high salt content. Salt in these foods can react with the metal, leading to discoloration, pitting, and even permanent damage.

To ensure the longevity of your stainless steel cookware, it’s essential to avoid cooking certain dishes notorious for their high salt content.

Popular Dishes That Should Not Be Cooked In Stainless Steel Due To Their Salt Content:

  • Soy sauce-based dishes: Soy sauce is a common ingredient in many Asian cuisines, but its high salt content can wreak havoc on stainless steel cookware. The salt in soy sauce can react with the metal, resulting in discoloration and even corrosion. It’s best to opt for alternative cookware materials when preparing dishes that heavily rely on soy sauce.
  • Brined meats: Brining is a popular method used to enhance the flavor and tenderness of meats. However, the salt in the brine can harm stainless steel cookware. When the brined meat comes into contact with the metal during cooking, it can form pits and stains. Consider using non-reactive materials such as glass or enamel-coated cookware for brining purposes.
  • Pickled vegetables: Foods like pickles and sauerkraut, packed with salt for preservation, should also be cooked in non-reactive cookware. The acidity and high salt content in these foods can cause stainless steel to rust, leaving marks and compromising its appearance.
  • Canned foods: Canned foods often contain added salt as a preservative. When these foods are cooked in stainless steel, the high salt content can react with the metal, resulting in corrosion. It’s advisable to heat canned foods in non-reactive cookware to prevent damage to your stainless steel pans or pots.
  • Marinades and salads with dressings: Certain marinades and gravies can contain high salt levels. When these sauces come into contact with stainless steel, they can lead to staining and even pitting. Opt for other cookware materials when marinating or tossing salads with salt-heavy dressings.

Invest in alternative cookware for these salt-rich recipes to prevent potential damage and keep your stainless steel looking its best for years.


Stainless steel is undoubtedly a popular choice for cookware due to its durability and sleek appearance. However, it’s essential to consider what not to cook in this material to avoid potential health risks and damage to your pots and pans.

Acidic foods like tomatoes, citrus fruits, and vinegar can react with the metal, causing a metallic taste and potentially harmful chemicals to leach into your food. Similarly, cooking highly alkaline foods like beets and asparagus can cause discoloration and pitting on the surface of stainless steel.

To prolong the lifespan of your cookware and ensure the safety of your meals, it’s advisable to use alternative cookware for these specific ingredients. By being mindful of what not to cook in stainless steel, you can continue to enjoy its many benefits while keeping your meals both delicious and safe.

Make informed choices about your cookware, and happy cooking!
