An Introduction to Runner Beans

Runner beans (Phaseolus coccineus) are a type of green bean that originated in Central America and was brought to Europe in the 16th century. They are vigorous climbers that can grow up to 2 meters tall on poles or trellises.
The beans grow inside long, flat pods that can range in color from green to purple to scarlet red. The pods are generally around 30 cm long. Inside the pods are small edible beans that can be green, white, pink, purple, red, or mottled in color.
Some common varieties of runner beans include Scarlet Runner, Painted Lady, Polestar, and White Emergo. Runner beans have a juicy, crunchy texture and a robust, nutty flavor.
When fresh, the pods and beans can be eaten whole or the beans can be shelled. The pods are stringless when young but develop fibrous strings as they mature. Runner beans are low in calories and are an excellent source of vitamins A, C, and K, magnesium, thiamin, fiber, folic acid, and antioxidants like beta-carotene.

Benefits of Freezing Runner Beans

Freezing is one of the simplest and most effective methods for preserving runner beans. Here are some of the key benefits:

Extends Shelf Life – Fresh runner beans only last about 5-7 days when refrigerated. Freezing them enables you to store them for 6-12 months.
Retains Nutrients – Blanching runner beans before freezing helps deactivate enzymes that can cause nutrient loss. Frozen beans have similar levels of vitamins, minerals, and antioxidants as fresh.
Locks in Flavor – Frozen runner beans maintain their bright green color and robust bean flavor. The texture remains crunchy when thawed.
Saves Money – Freezing runner beans enables you to preserve seasonal gluts and bulk purchases for enjoying throughout the year.
Adds Convenience – Having a stash of frozen runner beans makes it easy to add them to soups, stews, casseroles, and side dishes anytime.
Reduces Food Waste – Freezing excess fresh runner beans prevents them from spoiling and going to waste.

Selecting Runner Beans for Freezing

The key to delicious frozen runner beans is starting with high-quality fresh beans. Here are some tips for selecting the best beans to freeze:

Choose young, tender beans with smooth, firm pods no longer than 20 cm. Older, more mature beans will be tough and stringy.
Look for beans with a bright, vibrant green color. Avoid beans that are yellowing or have brown spots.
Select beans that snap easily when bent rather than bend. This indicates good freshness.
Check that the seeds inside are small. Large seeds indicate more mature beans.
Buy beans grown locally whenever possible for maximum freshness.
If buying in bulk, select beans of uniform length and thickness for even cooking.
Wash beans and check for any insect damage, bruises, or mushy spots. Avoid damaged beans.

How to Prepare Runner Beans for Freezing

Proper preparation is vital for beans that freeze and reheat well. Follow these steps:

Wash beans thoroughly under cool running water. Trim both ends and remove any strings along the seam of each pod using a paring knife or bean stringer.
Leave small beans whole. For longer beans, cut them into 2-3 inch pieces so they are easy to use after thawing.
Blanch beans by boiling a large pot of water and adding beans. Boil for 3 minutes, then immediately drain and plunge beans into an ice water bath to stop the cooking process.
Allow beans to cool completely in the ice bath, then drain well and pat dry with paper towels or a clean dish towel.
Arrange beans in a single layer on a parchment-lined baking sheet, making sure they are not touching. Place in the freezer until completely frozen, about 2 hours.
Transfer frozen beans to an airtight freezer container or zip-top freezer bag. Squeeze out excess air and seal.
Label the container with the bean variety and freeze date. Frozen beans are best used within 8-12 months for peak quality.

How to Freeze Different Types of Runner Beans

Runner beans can be frozen whole or cut in several ways:
Whole beans – Leave small, slender beans uncut. Blanch, cool, drain, and open freeze beans. Once frozen, transfer to bags.
Diagonal slices – Cut beans on the diagonal into thick ovals. Blanch, cool, and freeze as above.
French-cut – Slice beans into 1-2 inch pieces on the bias. Freeze as directed.
Diced – Good for soups and casseroles. Cut beans into 1/2 inch dice. Blanch diced beans for 2 minutes before freezing.
Shelled – For optimum texture, shell fresh beans by snapping off the ends and pulling down the seam. Blanch shelled beans for 1 minute before freezing.

Tips for Freezing Runner Beans

Follow these tips for best results with frozen runner beans:

Freeze beans as soon as possible after harvesting or purchasing.
Cool blanched beans rapidly in ice water to stop the cooking process quickly.
Use moisture-vapor resistant freezer bags or containers to prevent freezer burn.
Exclude as much air as possible and freeze beans in a single layer first to prevent clumping.
Avoid overcrowding bean packages to allow for good air circulation.
Store beans at 0°F or colder for optimal frozen storage.
Once thawed, use beans within 3-5 days for best quality. Do not refreeze.
Add frozen beans directly to simmering soups, stews, and casseroles to reheat gently.

How to Blanch Runner Beans

Blanching is a vital preliminary step before freezing runner beans. It inactivates enzymes that can cause loss of flavor, color, and texture during frozen storage. Follow these instructions:

Fill a large pot with water and bring to a rolling boil over high heat. Use 2 quarts water per 1 pound of beans.
Prepare beans by washing, trimming, and cutting as desired.
Add beans to the boiling water and blanch for 3 minutes (1 minute for shelled beans).
Drain beans immediately using a colander and then plunge into a large bowl of ice water for 3 minutes.
Drain beans again thoroughly and pat dry before open freezing on a lined pan.
Frozen beans should be blanched for 3 minutes before enjoying them in recipes to restore texture.

How to Freeze Runner Beans Without Blanching

It is possible to freeze unblanched runner beans if you plan to cook them directly from frozen. Here is the process:

Wash and trim whole runner beans. Leave uncut or cut into desired shapes.
Spread prepped beans in a single layer on a parchment-lined baking sheet. Freeze for 2 hours.
Transfer frozen beans to freezer bags or containers, removing excess air.
When ready to use, cook frozen beans directly in soups, stews, etc. until tender, about 5 extra minutes.
Add extra liquid when cooking unblanched frozen beans as they can dry out dishes.
Unblanched frozen beans won't have the same plump, crunchy texture as blanched beans but still taste good.

How to Store Frozen Runner Beans

Storing your frozen beans properly is key to preserving quality over months in the freezer. Follow these guidelines:

Allow blanched beans to fully freeze in a single layer before packing together in bags or containers.
Exclude excess air and press bags to remove as much as possible before sealing tightly.
Use high-quality, moisture-proof freezer bags or airtight rigid storage containers.
Attach labels noting bean type, date frozen, and any other details. Use oldest beans first.
Store beans at 0°F or below. Place bags toward the back of the freezer.
Avoid temperature fluctuations that can lead to frost build-up from moisture in beans.
Inspect bags periodically and use within 8-12 months for best flavor and texture.
