Pop popcorn kernels into a large bowl according to popcorn popper's directions.

In the meantime, melt butter (or measure olive oil) and set aside. In a small bowl, combine remaining ingredients.

Once popcorn has popped, combine seed mixture with the butter or oil and immediately pour it over the popcorn (if you let it sit, the garlic and onion absorb too much of the butter/oil, which makes it hard to mix in).

Stir well with a large spoon, scraping up the sticky seed, garlic, and onion mixture from the bottom and wiping it off the spoon (fingers work best) and back into the popcorn as you mix.

Transfer popcorn to serving bowls. Scoop up any of the remaining seed mixture and sprinkle it atop the prepared bowls. Enjoy!
