With tender seasoned hamburger patties smothered in pan-gravy, topped with a fried egg and crispy fried onions, Loco Moco is a mouthwatering Hawaiian classic that's easy to make and satisfying.

Loco Moco

With tender seasoned hamburger patties draped in mushroom pan-gravy, Loco Moco is classic Hawaiian comfort food that's as delicious as it is satisfying. My simple gravy uses pan drippings and caramelized mushrooms to load it up with umami, and it can even be packed into a bento box lunch.

Instructions

  1. Put the onions in a microwave-safe bowl, cover the bowl and microwave at 800 watts for 4 minutes. You want them to be soft, and just starting to brown. Leave the onions covered and let them cool enough to handle.

  7. Add the vegetable oil to a frying pan and heat over medium heat until hot. Break the eggs into the pan and then turn the heat down to low. Let the eggs fry until the white is cooked through and the yolk is done to your liking. Transfer the eggs to plate and set aside.
