Stainless Steel vs. Aluminum Pressure Cooker

Pressure cookers are used by home cooks worldwide to create perfect meals. They’re one of the most efficient ways to prepare delicious dishes. The two most popular models on the market are made of aluminum and stainless steel. Both are highly effective and reliable, but what if you want to go with stainless steel or aluminum?

The main difference between stainless steel and aluminum pressure cookers is that stainless steel pressure cookers are more expensive than aluminum pressure cookers. Stainless steel pressure cookers are also more durable and have a longer lifespan. Also, aluminum pressure cookers are not as safe as the ones made with a stainless steel pot because the aluminum can leach into food.

As a foodie, I can confidently say that if you’re serious about creating delicious meals at home, you need to invest in a good quality pressure cooker. This is especially true if you’re looking to create authentic Asian dishes, and you can turn out perfectly cooked meals using your own pressure cooker.

What Makes a Pressure Cooker Worth Buying?

Pressure cookers are an appliance that makes cooking simple by saving time and energy. Some pressure cooker models also help save money because the ingredients can be used for several meals instead of purchasing a separate pan and utensils for each dish.

A quality pressure cooker makes cooking with less oil or fat easier and healthier. It reduces the risk of foodborne illnesses, which, if left unchecked, can cause severe health problems. It also allows cooks to prepare meals faster than average without constantly checking and monitoring the temperature of the food. A pressure cooker is an excellent investment because it’s a kitchen appliance that can save you money in the long run.

While many pressure cookers don’t come with a timer, they have a few features that can make a difference. One is having a heat-resistant handle that’s easy to grip. Another is a lid with a tight seal. These features mean that a pressure cooker is safe to use on the stovetop, and it will continue to boil, simmer, and cook food safely.

Do You Need to Buy Both?

Whether you need to buy both depends on your preference. Stainless steel pressure cookers are more expensive than aluminum. While the aluminum pressure cookers can be scratched easily but last longer than stainless steel. If you have a budget and plan to cook a lot, I recommend buying both.

If you are planning to cook a lot, it is good to get two different types of pressure cookers. This way, you can always find one that you can use and another that you can use if you run out of your first cooker. However, if you are only cooking for yourself, you can probably get away with buying one type of pressure cooker.

Many people often only think of buying one pressure cooker when many different types have different advantages. Stainless steel pressure cookers are typically more expensive than the cheaper aluminum ones, but they are sturdier and don’t rust or corrode. Aluminum pressure cookers are usually more affordable, and they tend to leak. However, stainless steel pressure cookers are the way if you’re making soups, casseroles, and other foods that may need to be cooked at higher temperatures.

Which Is Better, Stainless Steel or Aluminum Cooker?

It’s tempting to focus on the shiny surface of the stainless steel pressure cooker versus the plainer aluminum. But it’s the stainless steel that’s better. While the exterior of the two products may be similar, the internal components are entirely different.

The inner liner of the aluminum cookware is likely made of cheap metal that’s prone to cracking, while the stainless steel pressure cooker’s liner is actually stainless steel.

Pros and Cons of Each Material

Both pressure cookers have their advantages and disadvantages. The following are the Pros and Cons of stainless steel and aluminum pressure cookers.

Stainless Steel Pressure Cooker


  • Stainless steel pressure cookers are made up of multiple layers that are way more durable and can last decades.

Aluminum Pressure Cooker

  • Aluminum pressure cookers weigh less, which means they’re easier to use and transport.
  • They cost less than stainless steel.
  • Cleanup is a breeze if you burn your food in the bottom of the pot because it doesn’t stick as it does on stainless steel.


  • If you burn your food in the bottom of the pot, cleanup takes time compared to stainless steel.

Is Aluminum Pressure Cooker Safe for Cooking?

Aluminum pressure cookers are absolutely safe for cooking. Aluminum has been used for centuries in the manufacturing of cookware, and, as long as it’s not burned dry, there are no health risks associated with cooking in an aluminum pot.

Some people choose stainless steel over aluminum because they have a personal preference for one material over the other. There’s nothing wrong with using an aluminum pressure cooker, but if you want a stainless steel one instead, that works too!

Is Stainless Steel Pressure Cooker Good for Health?

The stainless steel pressure cooker is cookware that comes with numerous health benefits. Stainless steel is non-toxic and easy to clean, meaning you don’t need to spend more money to keep your cooker spotless. It’s also non-corrosive, so you can cook anything inside of it, including meats and vegetables, without worrying about your food coming into contact with toxic metals.

A stainless steel cooker is excellent for cooking all types of food, and it’s a good choice if you are using your pressure cooker for canning. This material is also non-reactive to acidic ingredients, so it’s safe to use with tomato sauce or curry.

Another benefit of the stainless steel pressure cooker is that it doesn’t get too hot when cooking foods inside it. So, it will help you keep your food fresh, and you don’t have to worry about any harmful chemicals getting onto your food. You can also save money by using a stainless steel pressure cooker rather than aluminum cookware.


When you’re looking at different types of pressure cookers, stainless steel is often the best option. Stainless steel cooker is more hygienic than other materials. And, as long as you clean it properly, you shouldn’t have any issues with it.

An aluminum pressure cooker is a good option if your want a budget-friendly solution. Either way, both options are good choices, and you can make the right decision based on your own needs.
