I’ve been pressure canning for years and have tested multiple canners to preserve our homegrown food safely and efficiently. In this guide, I’ll walk you through the different types of canners, what to look for when buying one, and my top recommendations based on experience and trusted brands. Whether you’re just getting started or ready for an upgrade, this guide will help you find the best pressure canner for your needs.

Why Invest in a Pressure Canner?

Preserving the harvest is one of the most rewarding aspects of growing your own food. A pressure canner is an essential tool for safely preserving low-acid foods like vegetables, meats, poultry, and seafood. 

Unlike water bath canning, which is suitable for high-acid foods like pickles, salsas, and jams, pressure canning uses high temperatures to destroy harmful bacteria, ensuring your home-canned foods are safe to store and enjoy year-round.

This guide is for anyone looking to invest in a pressure canner—whether you’re a beginner ready to start preserving your own vegetables, soups, or meals in a jar, a homesteader aiming for food self-sufficiency, or an experienced canner looking to upgrade to a more reliable model. With so many options available, choosing the right pressure canner can feel overwhelming. 

In this article, I break down the key features to consider, compare popular models, and help you find the best pressure canner to fit your needs and budget.

How Pressure Canners Work

Pressure canners use high temperatures and pressurized steam to safely preserve low-acid foods like vegetables, meats, and soups. Unlike water bath canning, which relies on acidity to prevent spoilage, pressure canning raises the temperature inside the canner to at least 240°F (116°C)—hot enough to destroy harmful bacteria, including Clostridium botulinum, which causes botulism.

Here’s how it works:

1. The pressure canner and jars are prepared and preheated.
2. Food is prepared according to a safe canning recipe.
3. Warm jars are filled one at a time with the prepared food and placed back in the canner.
4. The lid is secured following the canner manufacturer instructions. 
5. The canner is heated, creating steam that forces air out through a vent.
6. Once venting is complete, the pressure builds to the required level, either monitored by a dial gauge or controlled by a weighted gauge pressure regulator.
7. The jars are processed at high pressure for a specific time, ensuring food safety.
8. After processing, the canner is allowed to cool naturally, and the pressure releases before the lid is opened.
9. Jars are removed and cooled completely for 12 to 24 hours.

By using a pressure canner, you can safely home can and store shelf-stable foods without refrigeration while maintaining flavor, texture, and nutrients.

Understanding the Different Types of Pressure Canners

Choosing the right pressure canner starts with understanding the different types available. From gauge types to size considerations, each factor plays a role in how the canner operates and suits your needs.

Dial Gauge vs. Weighted Gauge Pressure Canners

Pressure canners come with either a dial gauge or a weighted gauge to regulate pressure.

• Dial Gauge Pressure Canners: These feature a gauge that displays the exact pressure inside the canner. Because the accuracy of the gauge is essential for safe canning, it must be tested annually to ensure proper calibration.
• Weighted Gauge Pressure Canners: These use a weighted regulator that rocks or jiggles to indicate proper pressure levels, typically at 5, 10, or 15 PSI. Unlike dial gauges, weighted gauges do not require testing for accuracy.

Electric vs. Stovetop Pressure Canners

In recent years, electric pressure canners have gained popularity for their ease of use. However, it’s important to understand how they compare to traditional stovetop models.

Electric Pressure Canners

These models are designed to automate the canning process, making them especially appealing for beginners or those who prefer a more hands-off approach. They are ideal for small batch canning and can be used on any kitchen counter, eliminating concerns about stovetop compatibility. However:

• While some manufacturers claim their electric canners meet USDA safety standards guidelines, most have not undergone the same rigorous testing as traditional stovetop canners—and some have even failed independent testing.
• At this time, the only electric pressure canner I trust and recommend is the Presto Precise Digital Pressure Canner, as Presto is a well-established brand with over a century of experience in pressure canning.
• Multicookers (such as Instant Pots) are NOT safe for pressure canning. According to the National Center for Home Food Preservation (NCHFP), these appliances do not consistently maintain the correct temperature, pressure, or venting needed to ensure food safety. Using a multicooker for pressure canning can lead to under processed food and increase the risk of botulism.

Stovetop Pressure Canners

These are the gold standard for safe home canning. They rely on direct heat from a gas, electric, or induction stove and offer more control over the process, making them the most trusted and time-tested option for preserving low-acid foods. If you’re serious about long-term food preservation, a stovetop pressure canner is the most reliable and widely approved choice.

When investing in a pressure canner, it’s crucial to choose a reputable brand. The safety of off-brand pressure canners is unknown, replacement parts are difficult or impossible to find, and there is no way to test the dial gauges for accuracy.

For safe, high-quality, and well-supported pressure canners, I recommend sticking with trusted brands:

• All American: Known for their durability and dual-gauge system, these heavy-duty, metal-to-metal seal canners are designed to last for generations.
• Presto: A long-established brand offering affordable, dependable, easy-to-use pressure canners with readily available replacement parts.
• Mirro: A budget-friendly option featuring weighted-gauge pressure regulation, making them simple to use. However, note that they have a concave bottom and won’t work on glass or ceramic stovetops.

Size and Capacity

Pressure canners come in different sizes, typically measured by their liquid capacity. Choosing the right size depends on how much food you plan to can at once.

Larger canners save time when processing big harvests, but they take up more storage and may be too heavy for some stovetops.

Pressure Cooker vs. Pressure Canner: What’s the Difference?

It’s important to note that pressure cookers and pressure canners are not the same.

• Pressure Cookers are designed for fast cooking and meal preparation but do not reach or maintain the necessary pressure levels for safe food preservation.
• Pressure Canners are specifically built to safely process low-acid foods at high temperatures over a prolonged period.

If you plan to can vegetables, meats, or other low-acid foods, always use a pressure canner—not a pressure cooker—to ensure safety.

How to Choose the Right Pressure Canner

With so many pressure canners available, choosing the right one depends on your personal needs, kitchen setup, and food preservation goals. Here are key factors to consider before making your investment.

Consider Your Needs

Think about how often you plan to pressure can and how much food you’ll be preserving at a time. A small household that cans occasionally may need a different canner than a homesteader processing large harvests. Also, consider storage space—some pressure canners are quite large and require ample room for storage when not in use.

Work Within Your Budget

Pressure canners come in a wide range of prices, but you don’t have to spend a fortune to get a safe, reliable model. Whether you’re looking for an affordable starter canner or a long-term investment, there’s an option that fits your budget.

• Best Budget-Friendly Option: The Presto 16-quart Pressure Canner (01745) is an excellent choice for under $100. It’s lightweight, easy to use, and holds 7 quarts or 10 pints, making it perfect for small to medium batches. It’s an affordable and reliable entry point into pressure canning.
• Best High-End Option: The All American 21-quart Pressure Canner (AA 921) is a premium choice that, if properly maintained, can last a lifetime—possibly longer. With a metal-to-metal seal (no gaskets to replace) and both dial and weighted gauges, it’s built for heavy-duty canning and can process 7 quarts or 19 pints per batch.

No matter your budget, choosing a trusted brand ensures safe and successful canning. If you’re starting out, the Presto 16-quart is a solid, affordable option. If you plan to can in large batches or want a canner that will outlast you, an All American pressure canner is worth the investment.

How Much Food Will You Be Canning?

The size of your pressure canner determines how many jars you can process per batch. Choose a canner that aligns with your food preservation needs:

• Small Canners (16-quart): Holds 7 quart jars or 9 pint jars per batch—great for smaller batches or occasional canning. This size works well for my own household, as it allows me to preserve manageable amounts of food at a time.
• Medium to Large Canners (21-23 quarts and up): Fit 7 quart jars or up to 19 pint jars, with some models allowing for double-stacking of smaller jars. If you plan to preserve large amounts of food in bulk, a high-capacity canner will save time by processing more jars per batch.

What Type of Stove Will You Be Using?

Not all pressure canners work on every type of stove. Be sure to check your stove’s compatibility before purchasing:

• Gas and Electric Coil Stoves: Most pressure canners work well on these.
• Glass, Ceramic, or Smooth-Top Stoves: Many manufacturers advise against using heavy pressure canners on these surfaces, as they may crack the glass. Check your stove’s manual or contact the manufacturer for guidance.
• Induction Ranges: Traditional aluminum canners will not work on induction cooktops. However, Presto currently offers an induction-compatible pressure canner, and hopefully, more brands will follow suit.

Is There Enough Space Above Your Stove?

A pressure canner must fit securely on the stovetop with enough clearance above it to remove the jars without tilting. Some kitchens, including mine, have range hoods or overhead cabinets that limit space. Tall canners (21-23 quarts and larger) may not fit under a standard range hood. Always measure your available space before selecting a canner.

Dial Gauge vs. Weighted Gauge: Which One is Best?

Pressure canners come with either a dial gauge, a weighted gauge, or both.

• Dial Gauge Canners: Measure exact pressure and require annual testing for accuracy. Unfortunately, finding a location to test gauges can be difficult.
• Weighted Gauge Canners: Use a weight that rocks or jiggles to indicate pressure. These do not require testing and are generally more convenient.
• Dual-Gauge Canners: Some models include both a dial and a weighted gauge. While the dial may lose accuracy over time, the weighted gauge remains reliable.

I recommend a weighted-gauge canner or one with both options for ease of use and long-term reliability. The rocking motion of the weight is always accurate, even if the dial gauge drifts out of calibration.

Best Pressure Canners on the Market

If you’re investing in a new pressure canner for preserving low-acid foods, choosing a trusted brand is important. All American, Presto, and Mirro are well-established brands known for their reliability and availability of replacement parts. Avoid off-brand pressure canners, as they often lack support for replacement parts, and non-standard dial gauges cannot be tested for accuracy.

Below are my recommended pressure canners based on safety, quality, durability, and ease of use.
