Hard-Anodized vs. Stainless Steel Pressure Cooker

Pressure cookers are one of the best investments you can make in your kitchen. They allow you to make healthy and fast meals that will save you both time and money.

A pressure cooker is useful for anyone who wants to eat a healthy home-cooked meal but may not have a lot of time to make meals from scratch. Everyone can benefit from owning a pressure cooker, and they are convenient for parents, college students, or people with demanding jobs/lifestyles.

The question on everyone’s mind when purchasing a new pressure cooker is which one they should buy?

When most people think about this question, they think about which brand or model they should buy, should they buy a stovetop pressure cooker or an electric pressure cooker, and should they buy a cheap or expensive one?

However, people should also be asking themselves whether they should buy a hard-anodized aluminum pot or a stainless steel pot?

Let’s explore some of the benefits and drawbacks of each type so you can decide which one will work best for you!https://whichpressurecooker.com/instant-pot-duo-evo-plus-pressure-cooker-review/

What is a hard-anodized pressure cooker?

A hard-anodized pressure cooker is a hard-anodized aluminum pot.

Anodizing is when the aluminum is coated with a layer of oxide to make it highly durable, scratch-resistant, and non-stick.

Hard anodized pots are great for pressure cooking as they conduct heat better than stainless steel and won’t chip as cheap aluminum pots can.

Hard anodized pots are the fastest cookers on the market.

One of the significant drawbacks of hard anodized cookware is that they are not dishwasher safe, so cleanup will have to be done the good old fashion way, with your hands!

How do you anodize aluminum pots?

Aluminum is a naturally occurring metal that is quite soft and reacts with acidic foods. The term anodized means that the material has been oxidized, creating a protective layer on the surface of whatever you are trying to protect.

Anodizing is done by submerging the aluminum in a chemical bath and passing electricity through it. This produces an oxide on the outer surface of the aluminum. It is this oxide that turns the aluminum into a hard, smooth, and non-reactive metal.

This process creates a very durable and scratch-resistant surface on the outside of the aluminum pot. Since there are many different types of anodized aluminum, you can choose the hardness and thickness of the outer layer to protect your pots from inevitable wear and tears.

For example, if you are looking to buy a pressure cooker that will last you for years of everyday use, then a thicker pot with a more durable coating would be a better investment than one with less thickness.

What are some benefits of hard-anodized cookware?

Hard anodized cookware is inexpensive and extremely durable. Hard anodizing means that not only will your pot be scratch-resistant and non-stick but also that it will be longer lasting than other types of cookware.

Not only is the coating on this pot scratch-resistant, but the inner metal itself is exceptionally durable and can withstand a lot of wear and tear.

You will also appreciate the minimal amount of oil or butter needed to prevent foods from sticking to your pots while pressure cooking, which means fewer calories but maximum flavor!

Pros & Cons of Hard Anodized Pressure Cookers

  • Price
  • Great at conducting heat
  • Non-stick
  • Not easily scratched
  • Very durable
  • Not dishwasher proof
  • Maintenance is trickier

What is a stainless steel pressure cooker?

A stainless steel pressure cooker is a pot made from stainless steel. Stainless steel pots conduct heat well, are durable, and can be cleaned easily in the dishwasher.

Stainless steel is not very good at being non-stick, so you may find yourself spending more time scrubbing food off your dishes which will take longer than cooking in an anodized pot.

Having said that, stainless steel can be cleaned in the dishwasher, so if you don’t feel like scrubbing, you don’t have to.

In general, stainless steel pots are heavier and bulkier than hard-anodized ones, so this may be a consideration for those who have back problems or arthritis in their hands and fingers.

Also, remember when they are full of food and liquid, they are even heavier still.

What are some benefits of stainless steel pressure cookers?

Stainless Steel Pressure Cooker

Stainless steel pressure cookers are dishwasher safe, so cleanup will be a breeze if you own a dishwasher! You toss it in the dishwasher, and you’re good to go.

Stainless steel is also stain-resistant, meaning grease stains from foods like bacon won’t ruin your pots or pans. Also, since stainless steel does not scratch easily, it will last longer than a pot with a more delicate coating.

Pros & Cons of Stainless Steel Pressure Cookers

  • Price
  • No special maintenance
  • Dishwasher safe
  • Not easily scratched
  • Durable
  • Slow heat conductor
  • Isn’t non-stick
  • More expensive than anodized

Differences between a hard-anodized aluminum and stainless steel pressure cooker?

Difference between hard anodized and stainless steel pressure cookers

The main difference between anodized pressure cookers and stainless steel pressure cookers is in how they conduct heat.

Hard anodized cookware will conduct heat much better than stainless steel. Hard anodized pots are the fastest pressure cooking pots on the market.

Hard-anodized aluminum pots are also durable and last for years, and they are non-stick with most foods. The downside to anodized pots is that you can’t use them in a dishwasher so that cleanup will be laborious.

Stainless steel pressure cookers are not as good at conducting heat and will take longer to cook food. Stainless steel pots are also heavier and take more time to cool down after turning off the stove.

Stainless steel pots can be cleaned easier than hard-anodized ones because you can place them in the dishwasher. Stainless steel is also much cheaper than anodized aluminum, so if you’re on a budget, this may be the way to go for you.

Which type of material is better for cooking?

Honestly, both materials have their benefits and weaknesses.

A stainless steel pressure cooker is suitable for cooking with because it’s durable and easy to clean. This means that it won’t scratch easily, and you can wash your pots in the dishwasher without having to worry about them getting damaged.

They take longer to heat up than anodized pots and will cool down more slowly after turning off the stove. This may not be a big issue for many people, but many prefer the faster cooking speeds of an anodized pot.

An anodized pressure cooker is suitable for cooking because of its non-stick properties. If you don’t like scrubbing, this is the pot for you!

For fast cooking, it’s hard-anodized all the way.

Is hard-anodized safe for cooking?

Yes, hard anodized cookware is safe for cooking.

The aluminum in anodized cookware is sealed so it will not react with acidic food or leach into food. Unprotected, lightweight aluminum pots and pans are highly reactive to acidic ingredients like tomatoes – which can cause significant problems when you’re cooking. 

Is stainless steel safe for cooking?

Yes, stainless steel is safe for cooking.

The US Food and Drug Administration considers stainless steel safe for contact with food as long as it has 16% chromium. Some people claim that it is not relatively inert, but it is more stable than other cookware that may react with food (like copper or aluminum do).

Stainless steel is also durable and will last longer than any other type of cookware, ensuring it won’t break into pieces anytime soon!

Does food taste any different if cooked in a stainless steel pot vs. an anodized pot?

Personally, the food does not taste any different whether it is cooked in a stainless steel pot or an anodized pot. Food will taste just as great no matter which material your pressure cooker is made from.

Durability Extremely Highly
Dishwasher Safe No Yes
Heat Conductivity Strong Poor/Decent
Non-Stick Excellent Poor
Maintenance Rating Specific Easy
Price Reasonable Moderate/High


After reading the article and comparing both different types of pressure cookers, it should be clear that each has advantages and disadvantages.

Hard anodized pots conduct heat better and are faster at heating up than stainless steel ones. The main drawbacks to using hard-anodized pots are that they cannot be put in a dishwasher and need more care when cleaning than stainless steel pots.

In terms of cleanliness, some people prefer stainless steel pots because they can go in the dishwasher, and you do not have to worry about scratches on your cookware.

Heat conduction in a stainless steel pressure cooker may not be as fast as hard anodized (which is an excellent heat conductor), but it is no slouch and will reach temperatures quickly enough.

The main drawback to using stainless steel pots is that they are not non-stick, and you may end up spending more time scrubbing off food than you’d like.

Many people have no preference for which material their pressure cooker is made out of and think they both work the same way. Either an anodized pot or a stainless steel pot will do.

When choosing which material you want, the main thing to consider is personal preference – based on how well you like to clean your cooking utensils and whether or not you can stand waiting for them to heat up. 

Another factor that should be considered is that anodized pots are generally cheaper than stainless steel ones, which may end up saving you some money in the long run.

Additionally, hard-anodized pots are lighter in weight, so this might be a consideration in helping you decide which one is right for you.

So, choosing which material to go for is not as simple as just saying pick this or pick that. Both work exceptionally well, and it all comes down to personal preference.

Frequently Asked Questions
