    A loco moco is the perfect weeknight 30-minute meal with a tasty cooked hamburger patty stacked high over rice with a delicious mushroom sauce and a fried egg.  This Hawaiian comfort food will be a sure-fire family favorite!

    We’re huge fans of quick weeknight meals and since my daughter loves beef, we make Sloppy Joes, Meatloaf, and Chopped Steaks pretty regularly.

    Loco Moco

    Right out of the gate the name of this recipe seems crazy, I know, and the story behind it is pretty funny.  Legend has it that a group of kids from a local gym and their parents went into a diner in Hawaii and asked for something different than a sandwich and with a bowl of rice, hence this recipe.

    The loco part of the name obviously in Spanish, allegedly came from one of the kids from the gym who they called “Crazy George,” for the way he played sports.  Not sure where moco came from, but this word translates from Spanish to English as snot, gross I know.  My guess is the sunny-side egg that is placed on top would be the reason.

    This simple Hawaiian staple consists of a seasoned hamburger patty that is cooked to the desired temperature and served with white rice, mushroom gravy, and a fried egg over top with a garnish of sliced green onions.

    The Key to Perfect Fluffy Rice

    While personal preference, I’m a fan of fluffy rice.  Often times when cooking rice on the stovetop it becomes soggy and overcooked.  It’s my professional opinion that most package recipes for rice overcompensates for the amount of water causing this overcooked result.

    Since most long-grain rice recipes have a standard ratio of 1 ½ part water to 1-part rice, I counter that by doing a 1 ¼ parts water to 1-part rice.  Stick with this proportion for delicious fluffy rice.

    How to Make a Loco Moco

    Follow these brief procedures to make this loco moco recipe:

    Combine the ground beef with onions, garlic, soy, Worcestershire sauce, salt, and pepper and form into patties.

    Brown the patties in a large frying pan in a small amount of oil over medium heat for 3-4 minutes side or until browned.

    Making Perfect Gravy

    Gravy can always be tricky because too much flour can result in it being clumpy, not enough sometimes makes it too thin.  There are a number of things to consider when making it.

    Here are common issues and remedies.

    • If it’s clumpy – The only way around this is to strain it to get rid of the clumps. This is a result of too much flour and not enough fat when stirring it into the mushrooms.  A roux is equal parts weight of flour to fat, so consider that when you are adding the oil to the pan at the beginning.
    • Thin Gravy – This means there was not enough flour added to mushrooms. The way to fix this is to make a roux separately and whisk it into the gravy.
    • Too Thick – Often times this will occur if there is too much total roux and not enough liquid. The easiest way to counter this is by adding in more liquid.

    Recipe Chef Notes + Tips

    Make-Ahead: You can make this recipe up to 2 hours ahead of time, simply keep the hamburger patties into the gravy while covered in very low simmering heat.  Likewise, keep the rice warm.

    How to Reheat: Add the desired amount of beef and gravy to a saucepan and heat over low heat until hot.

    How to Store: Keep the meat and gravy separate from the rice, and cover and keep in the refrigerator for up to 5 days.  Do the same and keep in the freezer for up to 2 months.

    If the sauce is not to your desired thickness before adding in the cooked patties, simply add in a little slurry (2 tablespoons corn starch mixed with 1 tablespoon water).

    Since there was a lot of oil in the pan after cooking the hamburger patties, I drained half of it into a small skillet and used it to fry the egg.

    The meat patties do not need to be fully cooked through when browning them before removing them from the pan to make the gravy.

    Cook the fried egg to your desired amount of doneness.  It is recommended that the yolk be runny.
