Blanching fresh green beans is crucial before freezing them. This technique is commonly used by professional chefs to prepare beans for sautéing or salads. Blanching involves briefly boiling the beans and then cooling them down. This can be done with cold water or in the refrigerator. Blanching eliminates enzymes and bacteria that can alter the flavor and color of the beans, making them less nutritious. In this article, we will guide you through the process of blanching green beans.
Blanching Green Beans
Step 1. This method is suitable for blanching fresh green beans.
This method can be used for blanching fresh green beans. It doesn't matter what type of beans you are blanching. Firstly, beans are blanched to preserve their vibrant green color and to retain their flavor and nutrients.
- Dried beans are not blanched, as they are prepared differently.
Step 2. Clean the beans and prepare them for boiling.
Clean the beans and prepare them for boiling. Start by rinsing the beans under fresh running water to remove dust and dirt. If you're preparing whole beans, trim the ends of the pods from both sides.
Step 3. Also ensure to remove any dirt from the pods while blanching.
- If the pods are very long, you can cut them in half. This will not affect the blanching process and will help simplify cooking.
Step 4. Boil a pot of water.
Bring a pot of water to a boil. For every half kilogram of beans, you will need 4 liters of water. You don’t need to measure the water precisely; you can just estimate.
- You may add salt for flavor.
- Choose a large pot that can accommodate all the beans comfortably without overcrowding.
Step 5. Prepare a bowl of ice water.
Prepare a bowl of ice water. Fill a bowl with cold water and add a few ice cubes. After a few minutes, when the beans are cooked, you will need to transfer them to this ice water. It should be cold enough, not exceeding 15°C, to cool the beans effectively before they lose their flavor and nutrients.

- If the cold tap water makes your skin numb, you can use it without ice. However, the water will warm up to room temperature quickly if not used immediately, so it’s better to use ice.
Step 6. Boil the beans for three minutes.
Boil the beans in the boiling water for three minutes. Use a timer. Place the beans in the water and start the timer. The beans should be added only to boiling water. Green beans and snap beans should boil for three minutes, while other types may take 2-4 minutes depending on their size. The beans should be cooked but still crisp.
- If the water does not return to a boil within a minute after adding the beans, you have added too much water. Next time, use less water.
- You can use a steaming basket to cook the beans. Place the beans in a colander or sieve over a pot of boiling water and cover with a lid. This way, you won’t have to drain the water, and you can immediately start cooking the next batch of beans.
Step 7. Cool the beans.
Cool the beans. Once the beans are done, drain the water or lift them out of the pot if using a steamer. Place the beans in the ice water and wait until they cool down. You can drain the water using a colander or sieve.
- This rapid cooling process is sometimes referred to as "shocking."
- Leave the beans in the ice water for three minutes.
Step 8. Drain the water.
Drain the water. Once the beans are cool, drain the ice water or remove the beans using a spoon. Now the blanching process is complete. The beans can be used for lasagna, salads, or vegetable stews. Blanching is done to preserve the flavor, nutrients, and color of the beans.
Freezing Beans After Blanching
Step 1. Dry the beans after removing them from the cold water.
Dry the beans after taking them out of the cold water. After blanching and cooling, the beans can be frozen. First, they need to be dried to prevent ice crystals from forming. Use a paper towel for this.
Step 2. Place the beans in a resealable plastic or cellophane bag.
Put the beans in a resealable plastic or cellophane bag. It should be a zip-top bag. If you are using a plastic container, leave about 1.25 cm of space at the top, as the beans may expand during freezing.
- You can insert a straw into the bag to remove the air. Use the straw to suck out the air and seal the bag.
Step 3. Frozen beans can be stored for about 10 months.
Frozen beans can be stored for around 10 months. If blanched and frozen properly, they can be used within a year. However, it's best to consume them within the next few weeks.
Step 4. Thaw the beans before using them.
Thaw the beans before using them. Take the beans out of the freezer and let them thaw. After thawing, it’s best not to put them back in the freezer. Beans should not be refrozen as it will degrade their quality. To avoid this, freeze the beans in separate small containers.
