Canning & Freezing Beans: A Pantry for the Whole Winter
Preserving Beans – Here's How
Canning beans in high summer is one of the most traditional preservation methods there is. The result: complete meals from the jar, even once the garden has long gone to sleep.
Method 1: Freezing (Quick & Easy)
The gentlest method – color, flavor, and nutrients are almost completely preserved.
- Wash the beans, trim the ends, cut into 4–5 cm pieces.
- Blanch: 3 min. in boiling salted water, then immediately shock in ice water.
- Drain well and pat dry.
- Freeze in portioned bags or containers. Shelf life: 10–12 months. To use: straight from frozen into boiling water or the pan – no thawing needed.
Method 2: Canning in Jars
The classic method – shelf-stable without a fridge or freezer.
⚠️ Important: Beans are a low-acid vegetable – and at 100 °C the spores of Clostridium botulinum survive any duration, including 90 minutes. The preserve only becomes truly safe in a pressure canner (121 °C). Without one, the BfR recommends heating to 100 °C twice, one to two days apart – this lowers the risk considerably but does not eliminate it. And in every case: heat right through before eating.

Ingredients (per 500 ml jar):
- About 300 g trimmed beans
- ½ tsp salt
- Water (boiled)
- Optional: savory, peppercorns
Steps:
- Blanch the beans (5 min.), shock in cold water.
- Fill into jars, add salt and spices.
- Top up with boiling water to 2 cm below the rim.
- Seal the jars and process in a pressure canner per manufacturer instructions – or alternatively twice for 90 min. at 100 °C, one to two days apart. Shelf life: 1–2 years.
Method 3: Pickling (Sour Preserve)
For crunchy beans with a vinegar tang – great as a side dish or in salads.
- Put blanched beans with dill, garlic, and peppercorns into jars.
- Brine: bring 300 ml white wine vinegar + 300 ml water + 2 tsp salt + 1 tsp sugar to a boil.
- Pour over the beans, process 20 min. at 90 °C. Shelf life: 1 year.
Storing Dried: Dry Beans
If you want to harvest bush beans as dry beans:
- Let the pods ripen and dry fully on the plant (pods should rattle)
- Spread out on paper to finish drying for 2–3 weeks
- Store in jars in a cool, dark place → keeps for several years
- Soak overnight before cooking
