Cast iron skillets have earned their reputation for good reason. They’re incredibly durable, cook food beautifully, and can last for generations with proper care. Whether you’re cooking steaks, making cornbread, or preparing a roast, there’s a reason cast iron cookware has stood the test of time.
That said, cast iron isn’t the perfect pan for every job. While its versatility and natural nonstick surface make it a favorite among home cooks, it has a few drawbacks worth knowing. Before adding one to your kitchen or relying on it for every meal, consider these 10 things.
1. They’re Heavy
One of the first things you’ll notice about a cast iron skillet is how much heavier it is than stainless steel or aluminum cookware. Even an empty pan can feel cumbersome, and lifting it full of food can be difficult for some people. Moving a heavy skillet from the stovetop to the oven or grill also takes more effort than using a lighter pan.
2. They Need Regular Care
Unlike stainless steel cookware, cast iron needs a little extra attention to keep it in good condition. A thin layer of oil helps maintain the seasoning, which creates that natural non-stick surface and protects the pan from rust. Without proper care, even a quality skillet from brands like Lodge or Griswold can lose its seasoning over time.
3. Acidic Foods Can Be a Problem
Tomato sauce, vinegar-based recipes, citrus, and other acidic ingredients aren’t always the best match for traditional cast iron cookware. Cooking acidic foods for long periods can affect the seasoning and sometimes leave food with a metallic taste. For recipes that need to simmer for hours, stainless steel or enameled cast iron is often a better choice.
4. It Takes Time to Heat
Cast iron holds heat exceptionally well, but it doesn’t heat as quickly or as evenly as some other types of cookware. Hot spots and unevenness can develop if the skillet isn’t given enough time to warm up properly. While that heat retention is great for searing steaks, it can be inconvenient when you’re trying to prepare a quick meal.
5. Rust Can Develop Easily
Moisture is one of cast iron cookware’s biggest enemies. Leaving a skillet wet after washing or storing it in a damp cabinet can cause rust to form, sometimes surprisingly quickly. Fortunately, you can usually remove most surface rust, and an old skillet can often be restored with a little cleaning and reseasoning.

6. It Doesn’t Belong in the Dishwasher
Cast iron may handle high oven temperatures, but the dishwasher is another story. Prolonged exposure to water and harsh dishwasher detergents can damage the seasoning and encourage rust. Hand washing with warm water, a little dish soap, and a brush or sponge is usually all that’s needed to keep the skillet clean.
7. Delicate Foods Can Stick
A properly seasoned cast iron skillet develops a natural non-stick surface, but it doesn’t always perform like modern non-stick cookware. Eggs, delicate fish, and thin crepes can still stick, especially if the pan hasn’t been preheated properly or the seasoning is uneven. For foods that require a little more finesse, stainless steel or a dedicated non-stick pan may be easier to work with.
8. Some Cooking Oils Aren’t Ideal
Cast iron is often used for high-heat cooking, but not every oil handles that heat equally well. Oils with lower smoke points can burn, leaving behind sticky residue and making a mess of the cooking surface. Choosing an oil suited to your cooking temperature can noticeably affect how the pan performs.
9. It Holds Heat for a Long Time
One of the biggest advantages of cast iron is its ability to retain heat, but that can also make cooking more difficult. Once the skillet gets hot, lowering the burner doesn’t immediately lower the temperature. This can be frustrating when cooking foods that need quick temperature adjustments, although it’s excellent for steaks, roasts, and dishes that benefit from steady heat.
10. It Can Scratch Glass Cooktops
Cast iron works on many stovetops, including gas, electric, and induction, but it requires extra care on glass-top stoves. The skillet’s weight and any roughness on its bottom can scratch the surface if you drag the pan instead of lifting it. Dropping a heavy skillet onto a glass cooktop can also cause damage, so be careful when moving it around.
Frequently Asked Questions About Cast Iron Cookware
Can You Use Dawn Dish Soap on Cast Iron?
Yes, modern dish soap, including Dawn, is generally safe for a properly seasoned cast iron skillet. The idea that soap ruins cast iron largely comes from older cleaning practices that used harsher soaps. A small amount of mild dish soap usually won’t remove established seasoning, but you should dry the skillet thoroughly after washing.
Should You Throw Away a Rusted Cast Iron Pan?
Not necessarily. Most cast iron skillets with surface rust can be cleaned, dried, and reseasoned rather than thrown away. However, a skillet with serious cracks, structural damage, or extensive deterioration may no longer be suitable for cooking.

How Often Should You Season Cast Iron?
There’s no fixed schedule for seasoning a cast iron skillet because it depends on how frequently you use it and how well the cooking surface holds up. A well-maintained pan may go a long time without needing a complete reseasoning, while one with patchy seasoning, sticking problems, or rust may need attention sooner. Regular cooking with oil and proper cleaning can help maintain the surface naturally.
