Hibachi Volcano Tips
Use thick slices of onion to create a tall volcano.
Have the chef wear black (apron and chef coat) instead of white. The volcano flames will stand out better so your guest will see it in action.
Use alcohol that is at least 80 proof. I used vodka with great success.
Make sure the alcohol stays within the onion rings. You don’t want to end up with a hibachi fire that creates a dangerous situation!
Have your guests get their camera ready to take amazing videos of your cool presentation.
Blackstone Griddle
My choice of flat top griddle is a Blackstone Griddle. Pick from a gas griddle or an electric griddle. They come in various sizes, accessories, and options. Learn more at my New Owners Blackstone Griddle Buyers Guide! I own, use, and love my Blackstone 36″ Griddle, Blackstone 17″ Electric Griddle, Blackstone 22″ Griddle with Blackstone Pizza Oven Attachment, and Blackstone Griddle 5 Piece Accessories Kit.
How to Make an Onion Volcano
Pick the Right Onion: Select a large white onion. It’s size and layers make it ideal for creating the perfect volcano shape. The larger the onion, the bigger the volcano will be.
Cut the Onion: With a sharp kitchen knife, cut off both ends of the onion. Peel the onion so all the dry skin is removed. Make onion rings by cutting it 2 times for a taller onion volcano or 3 times for a shorter onion volcano. Tip the onion on its side and slice all the way through creating the rings.
How to Stack a Volcano Onion
Separate the Onion Rings: Use one slice of the whole white onion to make an onion tower. Starting with the outside ring, carefully, separate each onion ring without breaking the rings. Do this for all the rings.
Create the Hibachi Volcano: Place the largest onion ring onto the Blackstone Griddle. (The griddle should be preheated on medium heat.) Then take the next largest onion ring and stack it on top of the first ring. Continue doing this to create the onion stack.
What Liquid Is Used For An Onion Volcano?
Add the Oil: Pour a small amount of vegetable oil into the stacked onion inner layers. Be cautious not to overfill. One or two teaspoons will work. The goal is to have a thin layer of oil on the griddle in the middle of the onion ring.
Squirt Alcohol into the Volcano: Squirt about one tablespoon of 80 proof or higher of alcohol into the top opening of the onion tower towards the griddle so that it sits on top of the oil that you put in.
A Flaming Onion Volcano
Ignite the Volcano: With the onion volcano prepared, it’s time to create the fiery spectacle. Make sure the area around the griddle is safe before lighting the onion volcano. Carefully ignite the alcohol inside the chamber using a stick lighter. Stand back and watch as the flames shoot up, mimicking the eruption of a volcano.
Repeat Hibachi Flames: The volcanoes flames will only last a few seconds. The good news is that you can ignite it over and over again. Once the flame burns out, squirt some more alcohol into the top of the onion stack and re-light using the stick lighter. This process can be done again and again until the onion is cooked and collapses.
Put on a Show: As the flames dance and flicker in your hibachi volcano, you can add a touch of showmanship by telling griddle jokes or puns. Tap the spatula onto the griddle and flipping it in your hand. Use a squeeze bottle to squirt sake (or alcohol of your choice) into the mouths of willing adults. Your guests will be in awe and love the added touch!!

Onion Volcano – FAQ
When done carefully and with adult supervision, making an volcano at home can be safe. Ensure you follow safety precautions and use a long-reach lighter to ignite the alcohol.
While white onions are the most commonly used for their size and shape, you can experiment with other onion varieties if you prefer different volcano looks.
While onions are the classic choice, some creative chefs have used other ingredients like bell peppers or even halved watermelons for similar effects.
