How To Extract Juice From Onion

Onions, with their pungent flavor and powerful aroma, are not only popular ingredients in various cuisines but also possess several health benefits. Extracting juice from onions is a simple process that can be done at home using basic kitchen tools. The extracted juice is rich in essential nutrients, such as antioxidants and vitamins, that can boost the immune system and promote overall well-being.

Whether used for culinary purposes or as a natural remedy, onion juice offers a range of uses and advantages worth exploring.


To extract juice from an onion, follow these steps in detail:

1. Select a fresh onion:
Choose a firm and ripe onion that feels heavy for its size. This will ensure the best flavor and juice content.

2. Peel and chop the onion:
Start by removing the onion skin and cut off the top and bottom. Slice the onion in half from top to bottom, and then make horizontal cuts across each half. Finally, chop the onion into small pieces.

3. Use a blender or food processor:
Place the chopped onion into a blender or food processor. Make sure to use a container with a tight-fitting lid to prevent any juice from splattering.

4. Blend or process the onion:
Start with a low speed and gradually increase it as the onion breaks down. Blend or process the onion until it becomes a smooth puree.

5. Strain the onion puree:
Place a fine-mesh sieve or cheesecloth over a bowl or pitcher. Pour the onion puree over the sieve or cheesecloth, allowing the juice to pass through while catching any pulp or solids.

6. Press the puree:
Use a spoon or spatula to press down on the onion puree, extracting as much juice as possible. Continue pressing until no more juice comes out.

7. Collect and store the juice:
Transfer the extracted onion juice from the bowl or pitcher into a clean container or jar. You can store it in the refrigerator for up to a week. Remember to handle onions with caution as they may cause eye irritation. To minimize tear-inducing fumes, chill the onion in the refrigerator before peeling and chopping, or wear goggles while slicing.
