What You’ll Need Before You Start
Before diving into the process, make sure you have the right tools and ingredients ready. Preparation makes the canning experience smoother and much safer.
Essential Equipment
- Pressure canner (required for low-acid vegetables like green beans)
- Mason jars (pints or quarts)
- Two-piece lids (flat lids + screw bands)
- Funnel, ladle, and jar lifter

Table: Ingredients for 1 Quart Jar
| Ingredient | Amount |
|---|---|
| Green beans | ~1 ½ pounds |
| Salt (optional) | 1 teaspoon |
| Boiling water | As needed to fill jar |
Preparing Green Beans for Canning
Canning begins long before you turn on the pressure canner. Proper preparation ensures your beans look good, taste fresh, and stay safe on the shelf.
- Wash beans under cool running water.
- Trim both ends.
- Cut into 1-inch pieces.
- Choose your method: Hot Pack or Raw Pack.
- Hot Pack: Pre-boil beans for 5 minutes before filling jars. This reduces floating beans and creates better texture.
- Raw Pack: Place raw beans directly into jars, then add boiling water. This method saves time but can lead to uneven quality.
Step-by-Step: How to Can Green Beans
Hot Pack Method (Best Quality)
- Boil trimmed beans for 5 minutes.
- Pack beans loosely into jars.
- Add salt (optional).
- Pour boiling water over beans, leaving 1-inch headspace.
- Remove air bubbles, wipe rims, place lids and screw bands.
Raw Pack Method
- Place raw beans directly into jars.
- Add salt (optional).
- Pour boiling water into the jars, leaving 1-inch headspace.
- Seal jars.
Processing in the Pressure Canner
- Place jars on the rack inside the canner.
- Follow your canner’s instructions to build pressure.
- Processing times:
- Pints: 20 minutes at 10 pounds pressure
- Quarts: 25 minutes at 10 pounds pressure
- Adjust pressure based on your altitude.
When finished, allow pressure to return to zero naturally. Carefully remove jars and let them cool on a towel for 12–24 hours.
Common Mistakes to Avoid
Many beginners feel nervous about canning green beans, and that’s normal. The good news is, once you know the pitfalls, you can avoid them easily:
- Never use a water bath for green beans. They are low-acid and require pressure canning for safety.
- Do not overfill jars. Always leave 1-inch headspace.
- Don’t forget altitude adjustments. Higher elevations require more pressure.
- Always remove bubbles. Trapped air affects sealing.
Storing and Using Your Canned Green Beans
- After jars cool, check the seals by pressing down the lid center. A sealed lid won’t flex.
- Label jars with the date.
- Store in a cool, dark, and dry place.
- Best quality if used within 12 months.
Ways to Enjoy Your Canned Beans:
- Heat and season with butter, garlic, or onions.
- Toss into a casserole for an easy side.
- Add to soups, stews, or slow cooker meals.
