Ingredients: 4 bunches of green onions. 1 medium yellow onion. Olive oil.
Chop up the ingredients to 1 inch long pieces. Set aside or wipe with paper towel to remove excess water.
Put them in a medium size skillet. Add olive oil about 2/3 of the height of the onions. The onions will be cooked down very fast.
Put them over medium low heat. This is the key of making this rich flavor oil. High heat will burn the onions, leave them soggy and taste like spoiled onions. Medium low heat drains out the water of them slowly but makes them crispy and brown in the end.
Let it cook for at least 50 mins or until most of the onions are brown and crispy. It may take over an hour if you want them to be perfectly crispy.
Save them in a jar and enjoy them over noodles with salt and pepper.
