Cook the popcorn as per package directions, or as follows: Add the oil to a large, 3 quart or larger pot over medium heat. Add the popcorn kernels and cover, with the lid ajar.
Shake the pot back and forth every few minutes. Remove from the heat when the popping has slowed and most kernels are popped, approximately 7 minutes. Set aside.
While the popcorn is popping, make the seasoning mixture by combining the Parmesan, garlic powder, parsley, and salt. Mix to combine and adjust seasoning to taste.
When ready to serve, lightly drizzle the popcorn with approximately 1 teaspoon of oil. Just enough to wet the popcorn without it getting greasy or soggy. Stir to coat. Immediately sprinkle the seasoning on the popcorn and stir again to coat. Serve immediately.
Notes
It is best to use a neutral oil with no flavor like vegetable or canola oil.I am normally a big fan of fresh parmesan, however the ground canned version is best for this recipe.Make a large batch of the seasoning to have on hand!Get popcorn kernels here!To ensure a truly vegetarian popcorn, make sure the Parmesan you use is vegetarian.
