Spread the love

It’s quite fun to eat mushrooms grown by your own hands, but not so much when your budding mushrooms die due to improper sterilization. That’s why; it is a must for every mushroom cultivator to own at least one best pressure cooker for sterilization.

Believe it or not, a pressure cooker is one of the best mediums for this. As long as you have a suitable one, you won’t need to worry over unsterilized foodstuff and containers ever!

But which ones are the suitable ones? No worries! In this blog post, we‘ll be discussing the 10 market-leading pressure cookers for sterilization so you can make an informed decision when purchasing one.

Top 5 Pressure Cookers for Sterilization at a Glance

Things to Know Before Going to Product Details

The key behind sterilizing using a pressure cooker is the temperature and the pressure level or PSI (Pounds/sq-inch). Generally, a cooker that can reach 7 PSI can generate enough heat to kill off pathogens from your mushrooms.

But if you completely sterilize the growing mushroom to prevent contamination during the growth, you will need more PSI. The optimum PSI level requirement for this is 15 PSI. Therefore, it is perfect to buy one that is capable of reaching 15 PSI at the very least.

In the market, you can find many options with such qualifications. But be aware! Not all of them are of the same level. Prior research can help in selecting the perfect product suitable for your needs.

Our Helpful Size Guide

Pressure cookers can only be filled up to half of their total capacity, yet they are sized based on their total liquid capacity.

Generally, the most popular sizes for cookers for home cooking are 8-quart, 6-quart, and 4-quart from the largest to the smallest level. But for sterilization purposes, the size chart is a bit different. You will not be using the pot for cooking but to sterilize jars of foodstuff. Thus the size should be enough to fit in the jars.

To help you select the most suitable one, we have divided our selections into three parts based on their sizes and capacity. We have put them with a liquid capacity of 25-quart or more in the larger-sized section, 15-25-quart in the medium-sized section, and below 15-quart in the small-sized section.

Now that we know the size of the pressure cooking pot, let’s move on to the main part.

Medium-Sized Pressure Cookers

Presto 01781 Pressure Canner and Cooker

Presto 01781 23-Quart Pressure Canner and CookerThe Presto 01781 is one of the most popular choices of many serious mushroom cultivators for sterilizing substrate. This is because of its consistent performance, durably built quality, and perfect capacity.

This is a warp-resistant heavy-gauge aluminum-made pressure cooker that distributes heat evenly. It is 15.1 inches wide and 14.8 inches tall with a 12-pound weight.

With its 23-quart capacity, it can hold up to 24 half-pints jars of 7-quart of capacity. This means you will be able to sterilize a lot of substrate in a single batch. Do you want more? No worries, we have other options with 30-quart plus capacity.

The manufacturer says that it works on all the regular and smooth-top ranges but our experience says different. We will recommend not using it on LP gas burners and you need to be careful while using it for sterilization at its full capacity.

This is because it will be a heavy one to lift and move after filling it with water. Unfortunately, one of our glass top stoves was broken due to lack of attention. Hopefully, it will not happen to you.

You already know that 15psi is the optimum pressure for perfect sterilization. This unit is capable of reaching 15psi at ease. Just imagine how superhot the interior of the pressure pot will be then!

You can see the precise pressure level in the Deluxe pressure gauge. Also, you can keep the pressure at a constant level using the pressure dial gauge. Pretty cool, right?

Another significant feature of this cooker is its lid. It is equipped with an inner sealing ring and a pop-up pressure indicator. It also has an overpressure plug-equipped simple steam release mechanism. This design helps to keep the steam inside of the pot and prevent any explosions.

The pot itself comes with a rack. You can use it not only for separating jars from the bottom but also for double cooking. That means when in a rush, you will be able to cook or sterilize twice the amount in the same period.


  • Approved by the US Department of Agriculture
  • Equipped with heat-resistant handles and a strong-lock steel lid for safety
  • It has a 12-year warranty period
  • It creates the required pressure fast.
  • Safe and secure.


  • It is not dishwasher safe
  • You cannot use it on an outdoor LP gas burner


Overall, the Presto 01781 23-quarts is a good quality option at a budget-friendly price. Despite being ranked in the medium-sized cookers, it has near similar capacity to the 25-quart canners. You can try this one as an alternative to the All American 925 due to its quality and lower price.

T-fal 22-Quart Pressure Canner

T-fal 22-Quart Pressure CannerAnother example of a lightweight, medium-capacity is the T-fall 22-Quart Pressure Canner. This unit is 15.39 inches wide and 16.26 inches tall. Its weight is only 14.77 pounds.

Like the Presto 01781 23-quarts, the T-fall 22-Quart also has an aluminum body. Similarly, it can hold seven quart-sized jars due to its 20.82-liter capacity.

In a hurry? No need to worry, this unit with its adjustable 5psi, 10psi, and 15psi pressure level will lessen your cooking time up to seventy percent! Just check the instruction booklet, manually set the cooker, and keep waiting for a tasty meal.

The same goes for the disinfection process. Place the jars inside the pot, and put the pressure level to 15psi/the highest bar. Then keep waiting. Also, as its body is made of aluminum, you won’t need to fear that it will get worse due to rust.

Speaking of fear, it is everyone’s greatest fear that the pressure cooker will explode one day and will cause harm to everyone in the family. And to be honest, it is not much of an invalid fear either.

But with this superb cooker, you can put this fear on hold. Due to the manufacturer’s intense focus on ensuring safety level, the item possesses a five-point security system. This security system includes a handle-built-in pressure-monitoring device, a sure-locking lid system, and overpressure steam-release safety components.

Due to these measures, it has managed to gain an Underwriters Laboratories Inc certification for safety cooking. So, you and your family will be totally safe with this product.


  • Rust-resistant aluminum built for quick heating
  • Equipped with a deluxe pressure gauge dial
  • Comes with two cooking racks
  • Sure-locking lid to prevent opening the pressurized cooker
  • Even heat conduction at the bottom due to the thick floor


  • Suitable for only gas and electric coil stovetop
  • The gauge has no Psi markings


Like the Presto 01781 23-quarts, the T-fall 22-Quart is an affordable one with high qualities.

Hawkins Big Boy Pressure Cooker

Hawkins Big Boy Pressure CookerIf you are not too fond of complexity and in favor of simplistic products, this might be the one for you. The Hawkins 23-quart Big Boy Cooker is the perfect specimen of pressure canners based on simple designs.

The cooker itself is made of 4.8mm virgin aluminum and weighs about 15 pounds. Its 18.8×12.4×15.4-inches body, combined with sturdy handles covered in heat-resistant materials, makes moving the cooker a piece of cake.

The cooker’s valve is designed to ensure the build-up of a maximum psi of 15psi inside its body. Its preventive loss chain for vent weight makes sure that the pressure level remains the same until the process is complete.

That means that after it reaches 15psi, the pressure level will hardly drop. So you can just place your cans inside the cooker, place them on the stove and go on your merry way without worries. Feel free to take a nap after setting up an alarm!

To ensure your safety and reduce the risk of explosion, Hawkins 23-quart has an extra-strong goof-proof lid. This lid has a shielded double safety valve to expel excessive interior pressure.

To make sure that your cooker’s handles won’t break or dismantle suddenly, the handle has a solid steel handle bracket. There is also a sturdy integral pivot at the joining section of the handle and the body. These all work together in favor of increasing your safety.

It is a manually controlled model. But as you can see from the settings, you won’t have to do anything with this pot. Despite being called a manual, you won’t need to do any setting or such. Even the pressure level will set and get regulated by itself. All you’ll have to do is to keep waiting for the food to be cooked.


  • Lightweight, sturdy, rust-resistant, and long-lasting
  • Designed and tested to be leak-proof
  • Perfect for mass sterilization and cooking for a crowd
  • Simple design for easy usage and cleaning
  • Available at an affordable price


  • No multiple pressure settings

Like the Presto 01781 23-quarts, the Presto 01755 16-Quart is also made of aluminum.

Strangely enough, despite its lesser capacity than its counterpart, it can also fit in seven-quart jars together inside of it.

And the same goes for the pressure level. After all, a pressure cooker without a 15psi capacity can’t be called a suitable one for sterilization. Therefore, this one, too, can reach 15psi with ease like its larger counterpart.

Aside from the utility of the products, the Presto Company takes the safety factors of its customers very seriously as well. In order to reduce the risk of explosion, it has multiple features.

These features include a sturdy lid equipped with an inner sealing ring, a pop-up pressure indicator, and an overpressure plug-equipped simple steam release mechanism. These features of the lid help to keep the steam inside of the pot and prevent any explosions.

As a result, the Presto Company has managed to achieve certification from the US Department of Agriculture for its effectiveness and safety measures. Moreover, the lid also contains a pressure dial gauge to help you keep the pressure at a constant level.

With one glance, you’ll be able to understand whether your mushroom jars are being safely sterilized or not. Pretty good for a manual cooker, right?


  • Can simultaneously disinfect vegetables, meats, and poultry
  • Comes with a cooking rack
  • The package includes a cookbook and a care manual

What’s better is that its reduced size will only work in helping you with better maneuvering of the product.

Things to Consider Before Buying a Pressure Cooker for Sterilization

Now that we have finished learning about the top-notch pressure cookers available on the market, it is time to decide on which one to buy. But while they all seem gorgeous, not all of them are suitable for your needs.

You should check several factors about them before buying so that you can be sure that the one you are getting is the one for you.

Size of the Pressure Cooker

Pressure cookers are available in different sizes. Their sizes give them both advantages and disadvantages.

You should consider your needs and then decide on the most possible option. We suggest you count how many jars you need to disinfect in one sitting, then buy a corresponding model.

Materials Quality

Pay close attention to materials. They play a big part in the quality of the cooking. For example, stainless steel is not as great a heat conductor as aluminum.

But aluminum pots can be harmful to human bodies in long-term usage. It is better to look for a model that is made of steel but has some inner aluminum base.

Powering Method

This is very important. As you can see, not all models can work on the same type of power source.

Some can operate only with electricity, while some prefer gas. You should get one which fits in with your house’s kitchen.

Features of the Cooker

If you are in need of only a pressure pot, then it is simple. But if you want a pressure cooker with multiple features to make your life easier, you should pay close attention to the features it provides.

Too many features are not good all the time. You should clearly determine your needs first and then check the cooker exclusively for the availability of those features.

Psi and Heat Capacity

For sterilization, it is imperative that you have a psi level of a minimum of 15psi and a heat level of a minimum of 121C.

There are many options available in the market with these features. And again, there are some who don’t have them.

Therefore, make sure that the pressure canner you are buying supports these features. If you are partial to multiple psi level settings, you should check that of those settings, at least one supports 15psi.

Security Features of the Canner

You and your family’s health and life are essential. Therefore, carefully check out the safety features of the product before buying them.

Make sure to do some prior research. If the product you fancy has a history of bursting and security measure failures, it is better to switch to another option.
