Pressure Canning 101: What New Canners Need to Know

This post may contain affiliate links.

If you want to preserve vegetables, soups, meats, beans, and hearty homemade meals, learning pressure canning is one of the best kitchen skills you can develop.

Pressure canning allows you to safely preserve low-acid foods that cannot be processed in a regular water bath canner.

Once you understand the basics, it becomes a practical way to stock your pantry with ready-to-use homemade meals and ingredients.

This beginner guide covers the essentials of Pressure Canning 101 so you can start with confidence.

What Is Pressure Canning?

Pressure canning uses high heat created under pressure to safely preserve low-acid foods.

Because vegetables, meats, soups, and beans can contain harmful bacteria if not processed correctly, they require temperatures hotter than boiling water to become shelf stable.

That higher heat is achieved only in a pressure canner.

What Foods Need Pressure Canning?

Low-acid foods should be pressure canned using tested recipes.

Common examples include:

Green beans
Potatoes
Mixed vegetables
Mushrooms
Dry beans
Garbanzo beans
