Granite vs Stainless Steel Pots: Which Should You Buy?

By Melzware — 6 October 2026 · 8 min read

In the granite vs stainless steel pots debate, buy stainless steel if you want pots that last for decades, take any utensil and go in the dishwasher. Buy granite if you want food to slide out, cook with less oil and spend less upfront, and you accept you'll replace them in a few years. Most kitchens do best with stainless steel for boiling and stews, plus one or two granite pieces for the sticky stuff.

What Granite Pots Actually Are

Granite pots are not made of stone. "Granite" describes the speckled finish, not the material. Underneath is a pressed or cast aluminium body. On top is a non-stick coating with mineral particles mixed in, which gives the stone look and adds some scratch resistance.

That coating is usually a PTFE-based non-stick, the same family as the original Teflon. Some brands use a ceramic coating instead. The listing should tell you. If it only says "PFOA-free" and nothing else, it's almost certainly PTFE.

So granite non stick pots behave like any good non-stick pot. They heat fast because aluminium conducts heat well. They're light. And food releases with almost no oil, as long as the coating is in good shape.

What Makes a Good Stainless Steel Pot

A stainless steel pot has no coating at all. You cook directly on the metal. That's why it handles high heat, metal spoons and the dishwasher without any wear.

Stainless steel on its own spreads heat poorly, so the base is what separates a good pot from a cheap one. Look for one of these two builds:

• Encapsulated base. A thick disc of aluminium sealed into the bottom of the pot. It spreads heat across the base, though the walls stay thinner. Good for boiling, soups and stews.
• 3-ply (tri-ply). A layer of aluminium bonded between two layers of steel, right up the sides. Heat spreads up the walls too, so sauces scorch less. This is the better build and costs more.

Also check the grade. 18/8 (or 18/10) means 18% chromium and 8% (or 10%) nickel. That's the food grade used in good stainless steel cookware. It resists rust and won't react with tomatoes, lemon or vinegar.

Granite vs Stainless Steel Pots: Side by Side

Are Granite Pots Safe?

Yes, if you use them the way they're designed to be used. Here's what the safety question is actually about.

PFOA vs PTFE

PFOA is the chemical that gave old non-stick its bad name. It was used to make PTFE coatings and has been phased out of cookware. That's what "PFOA-free" on a label means. The American Cancer Society explains where PFOA was used and why it was dropped. Our granite sets are listed as PFOA-free.

Heat is the real risk

PTFE starts to break down at around 260 °C. A pot with food or water in it on medium heat never gets close. An empty pot left on a high plate can pass that in a few minutes. So never preheat a granite pot empty, and keep the dial at low to medium.

Scratches and flaking

Once the coating is deeply scratched or starts to flake, food sticks and the pot has done its job. Replace it. Swallowing a small flake isn't considered harmful, but there's no reason to keep cooking on a coating that's breaking up.

What about stainless steel?

Stainless steel has nothing to wear off and no heat limit you'll reach on a stove. The one caveat: 18/8 steel contains nickel. Most people are unaffected, but if you have a diagnosed nickel allergy, talk to your doctor before switching.

What Each Pot Cooks Best

Use granite for

• Eggs, omelettes and pancakes
• Oats, mealie meal porridge and pap
• Rice, especially if you hate soaking a pot overnight
• Delicate fish
• Milk-based sauces and custard that catch on the bottom

Use stainless steel for

• Boiling pasta, potatoes and vegetables
• Stews, curries and soups, especially tomato-based ones
• Browning meat and onions before a slow cook
• Stock and big-batch cooking
• Anything that goes from stove to oven

Heads up: the brown bits that stick to a stainless steel pot when you brown meat are not a problem. They're flavour. Add a splash of water, wine or stock and scrape them into the sauce. Granite can't do that, because nothing sticks to it in the first place.

Care and Lifespan

Making granite pots last

• Wash by hand with a soft sponge. Dishwasher detergent wears the coating faster.
• Let the pot cool before it goes in water. Sudden temperature changes can warp thin aluminium.
• Use silicone or wooden utensils, never metal.
• Skip aerosol cooking spray. It leaves a sticky film that builds up and ruins the release.
• Stack with a cloth or paper towel between pots so the bases don't scratch the insides.

Making stainless steel pots look new

• Preheat for a minute or two, then add oil, then add food. This is most of the anti-stick trick.
• For burnt-on food, simmer water with a spoon of bicarbonate of soda for five minutes, then scrub.
• Rainbow stains are from heat or minerals. A splash of white vinegar takes them off.
• Salt water left standing can pit the surface. Add salt once the water is boiling, not before.

Look after a stainless steel pot and it will outlive the argument about whose turn it is to wash it.

Cost Per Year: The Number That Settles It

Granite pots look cheaper on the shelf. Over time they usually aren't. Here's our opinion, using our own prices.

Our 8-piece granite non-stick set costs R1,399. If the coating lasts three years of daily cooking, that's about R466 a year. Our 3-ply stainless steel set of 5 costs R2,499. If it lasts 20 years, and good stainless steel easily does, that's about R125 a year. Even at ten years, it's R250 a year.

So stainless steel costs nearly four times less per year of use. Granite still wins if you need pots now on a tight budget, or if you're furnishing a rental or student flat for a year or two. For a kitchen you'll cook in for the next decade, stainless steel is the better buy.

Which Should You Buy?

Buy stainless steel if

• You cook most days and want pots that last.
• You boil, brown, braise and make big batches.
• You want everything in the dishwasher.
• You cook on induction. Our 3-ply set works on induction, gas, electric and ceramic plates.

Buy granite if

• You mostly cook eggs, porridge, rice and quick meals.
• You want to cook with less oil.
• You find heavy pots hard to lift.
• You need a full kitchen on a smaller budget. The 23-piece granite set covers everything from day one.

Don't buy either if

Straight up: if your current pots aren't warped, peeling or scorching your food, keep them. A new set won't make you a better cook. And if you only struggle with eggs and porridge, you don't need a full set. One granite pot added to the pots you already own solves that problem for far less.

For most households, our answer is both: a stainless steel pot set for everyday cooking, and one or two granite pieces for the sticky jobs. See the full range in our pots collection.

Frequently Asked Questions

Are granite pots safe?

Yes, when used as intended. Most granite pots are aluminium with a PFOA-free non-stick coating. Keep the heat at low to medium, never heat an empty pot, and use wooden or silicone utensils. Replace the pot once the coating is badly scratched or flaking.

How long do granite pots last?

With daily use, expect two to five years before the non-stick starts to fade. Hand washing, low to medium heat and soft utensils push that towards the top of the range. A good stainless steel pot lasts decades.

Can you use metal utensils on granite pots?

It is best not to. Metal spoons and whisks scratch the coating, and every scratch shortens its life. Use wooden, silicone or nylon utensils. Stainless steel pots take metal utensils without any problem.

Why does food stick to my stainless steel pot?

Usually because the pot was not hot enough before the food went in, or the food was moved too early. Heat the pot for a minute or two, add oil, then add the food and leave it until it releases. For boiling, stews and soups, sticking is rarely an issue.

Do granite pots work on induction?

Only if the base has a magnetic steel plate. Plain aluminium does not work on induction. Check the listing for induction compatibility. Most stainless steel cookware works on induction, but a magnet that sticks firmly to the base is the quickest test.

Is granite or stainless steel healthier to cook with?

Stainless steel has no coating to wear or overheat, so it is the lower-maintenance choice for health. Granite lets you cook with less oil. Both are safe when used correctly. If you have a nickel allergy, ask your doctor before buying 18/8 stainless steel, which contains about 8% nickel.
