Cast Iron vs. Stainless Steel: When to Use Each

Some nights, dinner starts with a steak and a hot skillet. Other nights, it’s a pot of tomato sauce that will simmer until everyone gets home. Cast iron and stainless steel can both do a lot, but the meal you’re making often gives you a good reason to reach for one over the other.

If you have both in your kitchen, you’ll probably use both regularly. Here’s how we choose between them, from a quick pan sauce to Sunday morning pancakes.

A Quick Guide to Choosing Your Pan

What you’re cooking	A good choice	Why
Steak, burgers, or crisp potatoes	Cast iron or stainless steel	Both can brown well. Cast iron is especially useful when you want a pan that holds heat.
A long-simmered tomato sauce or an acidic reduction	Stainless steel	Its nonreactive cooking surface suits extended cooking with acidic ingredients.
Chicken followed by a wine or stock pan sauce	Stainless steel	It’s well suited to browning food, then deglazing the browned bits into a sauce.
Cornbread, skillet cookies, or a baked breakfast	Cast iron	A seasoned skillet works well as a baking pan and serving dish.
A dish that needs frequent heat adjustments	A responsive stainless steel pan, or lightweight cast iron	Many clad pans with aluminum or copper layers respond more readily than a heavy cast iron skillet.
Pancakes, eggs, or grilled sandwiches	Well-seasoned cast iron	With suitable heat and enough fat, the seasoned surface is useful for everyday breakfast cooking.

Reach for Cast Iron When You Want Browning and Retained Heat

Cast iron is a good choice for a seared steak, burgers, roasted potatoes, or vegetables you want to develop some color. Once warmed, the skillet holds heat well. That makes it useful for foods that benefit from sustained contact with a hot cooking surface.

Give it time to preheat gradually, and leave enough room around the food. A crowded skillet can steam ingredients rather than brown them. The same applies to stainless steel: the material matters, but so do the pan size, moisture on the food, and how much you put in at once.

Stainless steel can produce an excellent sear, too. Choose cast iron when heat retention suits the job and you enjoy cooking on a seasoned surface. Choose stainless when you also want to build a sauce in the pan afterward.

Reach for Stainless Steel for Tomato Sauces and Acidic Reductions

For a tomato sauce that will simmer for a long time, stainless steel is an easy choice. Its nonreactive surface is well suited to tomatoes, wine, vinegar, and citrus.

Seasoned cast iron can handle some acidic ingredients, particularly once its seasoning is established. A squeeze of lemon at the end of cooking is different from simmering an acidic sauce for an extended period. Prolonged acidic cooking can affect the seasoning and sometimes the flavor, so stainless steel saves you that consideration.

This distinction applies to seasoned, uncoated cast iron such as Lancaster cookware. Enameled cast iron has a different cooking surface and its own care instructions.

Use Stainless Steel When the Pan Sauce Is Part of Dinner

After browning chicken, pork chops, or mushrooms, the browned bits left in the pan can become the beginning of a sauce. Add wine or stock, scrape them up, and reduce the liquid before finishing the sauce.

Stainless steel is particularly useful for this style of cooking. You can sear, deglaze, and reduce in the same pan, including with acidic ingredients. Its lighter-colored interior can also make changes in browning easier to see.

How quickly a stainless pan responds to the burner depends on its construction. Clad cookware often combines stainless steel with more conductive metals such as aluminum. A thin stainless pan and a substantial multilayer pan won’t behave exactly alike.

Use Cast Iron for Baking and Breakfast

Cast iron earns its place when the skillet becomes the baking dish. Cornbread, a chocolate chip cookie, or a baked breakfast can go from oven to table in the same pan. Match the skillet size and preparation method to the recipe; not every bake calls for a preheated pan.

Our Cast Iron Skillet Chocolate Chip Cookie and Rosemary and Orange Olive Oil Cake both use a Lancaster No. 8 skillet.

For stovetop breakfasts, a well-seasoned skillet is useful for pancakes, eggs, and grilled sandwiches. Start with moderate heat and enough butter or oil. If eggs stick, a hotter burner usually isn’t the first thing to try.

Many stainless steel pans also move from stove to oven. Check the manufacturer’s limits for the pan, handles, and lid rather than assuming every piece has the same rating.

Choose the Care Routine That Works for You

Stainless steel needs no seasoning. Follow its maker’s cleaning instructions, including whether dishwasher use is recommended. Deglazing can loosen some residue after cooking; stubborn marks may need additional cleaning.

Cast iron calls for a different routine: wash it, dry it thoroughly, and maintain the seasoning. Mild dish soap is fine. Keep it out of the dishwasher and don’t leave it soaking. You don’t need a full oven-seasoning session after every meal.

Both materials can serve a kitchen for many years with appropriate use. Neither needs to be described as disposable to explain the appeal of the other.

Where Lancaster Fits in Your Kitchen

If you already own stainless steel, a Lancaster skillet gives you another useful surface to cook on. Keep the stainless saucepan for tomato sauce and the sauté pan for dinner with a reduction. Bring out cast iron for cornbread, breakfast, roasting, or the sear you have in mind.

The No. 8 is our everyday starting point: a 10.5-inch skillet weighing about four pounds, made in Lancaster, Pennsylvania, with a smooth, pre-seasoned cooking surface. The No. 10 offers more room when you regularly cook larger portions.

Choose the pan for the meal. A kitchen with both stainless steel and cast iron gives you plenty of ways to make it well.
