Can You Can Green Beans And Potatoes Together

Yes, you can can green beans and potatoes together safely and deliciously, but there are some important rules to follow.
 
Combining these two pantry staples in one jar saves time and gives you a ready-made side dish that’s hearty and satisfying.
 
While you can can green beans and potatoes together, you need to respect each vegetable’s processing requirements to avoid unsafe results.
 
The key is understanding that both are low-acid foods, which means they must be processed in a pressure canner, not a water bath.
 
In this post, we’ll walk through why you can can green beans and potatoes together, how to prep them properly, and the step-by-step method that keeps your jarred combo safe and tasty.
 
Let’s dig into this practical kitchen project so you can fill your shelves with confidence.
 

Why You Can Can Green Beans and Potatoes Together

You can can green beans and potatoes together because they share the same acidity level and require the same processing method.
 
Both green beans and potatoes are low-acid vegetables with a pH above 4.6.
 
That means you can safely combine them in a single jar as long as you use a pressure canner set to the correct pressure for your altitude.
 
The processing time for the combined mixture is based on the vegetable that needs the longest time, which in this case is the potatoes.
 
So when you can green beans and potatoes together, you’re not cutting any corners; you’re simply packaging two like-minded vegetables that get along perfectly in the canner.
 

1. Both Vegetables Are Low-Acid Foods

The reason you can can green beans and potatoes together starts with their acidity profile.
 
Green beans typically have a pH around 5.0 to 5.5, and potatoes also fall in the same low-acid range.
 
Low-acid foods are prone to botulism if not heated enough, so they must be pressure canned at temperatures above 240°F.
 
That shared requirement means the same canner settings work for both.
 
By combining them, you simplify your canning day because you don’t need separate batches or different pressures.
 

2. Potatoes Set the Processing Time

When you can green beans and potatoes together, the processing time must be generous enough to handle the densest ingredient.
 
Potatoes are denser than green beans, so they take longer to heat all the way through.
 
Standard guidelines suggest processing pint jars of this combo for 75 minutes and quart jars for 90 minutes at 10 to 15 PSI depending on your altitude.
 
If you were canning green beans alone, you’d process them for the same 75 or 90 minutes anyway.
 
So adding potatoes doesn’t lengthen your time; it just makes every jar a complete meal starter.
 

3. Flavor and Texture Work Beautifully Together

Beyond the science, you can can green beans and potatoes together because they taste amazing as a duo.
 
The green beans stay somewhat crisp while the potatoes turn tender and creamy during processing.
 
Both vegetables absorb the same seasonings, like salt, pepper, or a bit of bacon, so they mingle well in the jar.
 
This combo is a classic southern or rustic farmhouse side dish, and having it pre-canned means dinner comes together in minutes.
 

How to Prep Green Beans and Potatoes for Canning Together

Before you can can green beans and potatoes together, you need to prep each vegetable with care.
 
Start by washing your green beans thoroughly and snapping off the stem ends.
 
You can leave the beans whole or cut them into one-inch pieces, whichever you prefer for your recipes.
 
For the potatoes, peel them and cut them into uniform cubes, about one to one and a half inches across.
 
Uniform pieces ensure even heat penetration so you can safely can green beans and potatoes together.
 

1. Hot Pack the Potatoes First

Some home canners wonder if they should blanch potatoes before canning them with green beans.
 
The answer is yes, and it’s easy to do.
 
Boil your potato cubes in water for about 10 minutes until they’re partially cooked but still firm.
 
This hot pack method helps remove excess starch and makes it easier to can green beans and potatoes together without cloudy liquid.
 
Drain the potatoes and keep them hot while you prepare your jars.
 

2. Pack the Jars in Layers

To evenly distribute the vegetables, pack your jars with alternating layers as you can green beans and potatoes together.
 
Add about one cup of potato cubes at the bottom of each clean jar.
 
Then fill the rest of the jar with green beans, leaving about one inch of headspace at the top.
 
You can also mix them loosely instead of layering, but layering often gives a prettier finished look.
 
Tamp down gently with a bubble remover tool to release trapped air pockets.
 

3. Add Salt and Boiling Water

Salt isn’t needed for safety when you can green beans and potatoes together, but it does enhance flavor.
 
Add about half a teaspoon of canning salt to each pint jar, or a full teaspoon for quart jars.
 
Pour fresh boiling water over the vegetables, keeping that one-inch headspace.
 
Be sure the water covers the veggies completely, and wipe the jar rims clean before putting on two-piece lids.
 

Step-by-Step Pressure Canning Process for the Combo

Once your jars are packed, you’re ready to pressure can green beans and potatoes together.
 
Set your pressure canner on a clean counter and add about two to three inches of hot water.
 
Place your filled jars in the canner rack so they don’t touch each other.
 
Lock the lid in place and turn the heat to high to vent steam for a full 10 minutes.
 
After venting, place the pressure regulator on and let the canner build pressure.
 

1. Process at the Right Pressure for Your Altitude

When you can green beans and potatoes together, altitude determines your exact PSI.
 
At sea level up to 2,000 feet, use 10 PSI with a weighted gauge or 11 PSI with a dial gauge.
 
Above 2,000 feet, you’ll need to raise that pressure to 15 PSI to achieve safe temperatures.
 
Check your local elevation before starting, as getting this wrong can ruin a batch.
 

2. Time Your Batch Precisely

Process pint jars filled with green beans and potatoes together for 75 minutes.
 
Process quart jars for 90 minutes, keeping the pressure steady.
 
Adjust the heat as needed to maintain the required PSI throughout the entire cycle.
 
Do not start counting time until the canner reaches the correct pressure.
 
When the timer goes off, turn off the heat and let the canner cool naturally for 30 to 40 minutes.
 

3. Never Rush the Cooling and Sealing Stage

After you can green beans and potatoes together, patience is your best friend.
 
Don’t force-cool the canner by running water over it, as that can cause siphoning or broken seals.
 
Wait until the pressure gauge reads zero, then remove the lid carefully with the steam facing away from you.
 
Lift jars out and set them on a towel-covered surface, leaving space between them.
 
Let them cool completely for 12 to 24 hours before checking that each lid has popped down in the center.
 

So, Can You Can Green Beans and Potatoes Together?

Yes, you can can green beans and potatoes together.
 
It’s a safe, practical, and tasty way to preserve two vegetables that naturally belong in the same pot.
 
Because both are low-acid, pressure canning is non-negotiable, and processing times should follow potato guidelines.
 
With proper prep, hot packing, and careful pressure management, you’ll have jars of this comforting duo ready for soups, stews, or a simple side dish.
 
So next time you’re staring at a basket of green beans and a bag of spuds, remember you can can green beans and potatoes together with total confidence.
 
Now grab your pressure canner and give this hearty combo a try.
