Induction Cookware Guide: How to Tell If Your Pots and Pans Will Work

Induction cooktops are fast, responsive and easy to wipe clean, but they only work with the right cookware. If you’ve just moved to an induction range or are thinking about one, the good news is that you may already own pans that work. Here’s how to check, what to look for when you buy, and which materials to skip.

How induction cooking works

An induction cooktop doesn’t heat the glass surface directly. Instead, a coil under the glass creates a magnetic field. When you set a pan with a magnetic (ferrous) base on top, that field makes the pan itself heat up. The glass only gets warm from contact with the hot pan.

That’s why induction feels so quick and controllable, and also why cookware matters so much: if the base isn’t magnetic, nothing happens.

The magnet test

The simplest way to check any pan is with a fridge magnet:

• If the magnet sticks firmly to the bottom, the pan should work on induction.
• If it sticks weakly, the pan may heat slowly or unevenly.
• If it doesn’t stick at all, the pan won’t work on its own.

Many pans also carry an induction symbol (a coil-shaped icon) on the base or packaging.

Materials that work on induction

Cast iron and enameled cast iron

Cast iron is naturally magnetic and works very well. It heats more slowly than thinner pans but holds heat beautifully for searing and braising. Enameled cast iron works too. Lift heavy pieces rather than sliding them so you don’t scratch the glass. Our Dutch oven guide covers what to cook in one.

Stainless steel with a magnetic base

Not all stainless steel is magnetic. Many good stainless pans use a layered base with a magnetic stainless layer on the outside and aluminum inside to spread heat. The CRISTEL 1826 stainless steel frying pan is built this way: the maker lists a three-layer, induction-compatible base of induction stainless steel, aluminum and 18/10 stainless steel, and it comes in five sizes from 8 to 12 inches.

Carbon steel

Carbon steel is magnetic, lighter than cast iron and a favorite for stir-fries and searing. It needs seasoning like cast iron. See our comparison of cast iron, stainless and carbon steel.

Non-stick pans with an induction base

Many non-stick and ceramic-coated pans now have a steel plate bonded to an aluminum body. Check the base with a magnet or look for the induction symbol before you buy.

Materials that won’t work on their own

• Plain aluminum and copper aren’t magnetic, so they won’t heat unless they have a bonded steel base.
• Glass and ceramic cookware won’t work on induction.
• Some stainless steel (often thin, single-layer pieces) isn’t magnetic enough. Use the magnet test.

Induction “interface discs” (flat steel plates that sit between the cooktop and a non-magnetic pan) exist, but they heat more slowly and lose much of induction’s speed. They’re best for an occasional favorite pan, not everyday cooking.

What to look for when you buy

A flat, wide base

Induction heats only the part of the pan touching the cooking zone. A flat base that sits evenly on the glass heats best. If a pan rocks on the counter, it will heat unevenly.

The right size for your cooking zones

Most induction zones need the pan to cover a minimum area before they switch on. Very small pans or espresso pots may not be detected. Check your cooktop manual for the minimum size.

A layered base for even heat

Magnetic steel alone can heat in a pattern that matches the coil underneath. A layered base with aluminum inside spreads heat more evenly across the pan, which helps with pancakes, sauces and anything that scorches easily.

Handles and lids that suit how you cook

If you like to start on the stovetop and finish in the oven, check the maker’s oven-safe rating for the handle and lid. The CRISTEL Strate saucepan with lid is 18/10 stainless steel with a base the maker lists as induction-compatible, and its detachable handle lets the pan stack for storage or go to the table as a serving dish. Our post on cookware with removable handles explains the pros and cons.

Tips for cooking on induction

• Start lower than you think. Induction heats quickly, so medium on induction can feel like high on gas.
• Don’t heat an empty pan on high. Thin or coated pans can overheat fast.
• Lift, don’t slide. This keeps the glass free of scratches.
• Wipe spills once the glass is cool. Spills don’t usually burn on the way they do on radiant tops, because the glass itself stays cooler.

FAQ

Does all stainless steel work on induction?

No. Some stainless steel isn’t magnetic. Try a magnet on the base; if it sticks firmly, the pan will work.

Can I use cast iron on an induction cooktop?

Yes. Cast iron works very well. Lift it on and off rather than sliding it across the glass.

Do I need to buy all new cookware for induction?

Not necessarily. Test what you already own with a magnet. Many cast iron, carbon steel and stainless pans already work.

Why won’t my induction burner turn on with a pan on it?

The pan may not be magnetic, or it may be too small for that cooking zone. Try a larger pan or check the minimum size in your manual.
