Rich & Hearty Hawaii Comfort Food – No Frills, No Fuss!

Most of the Hawaii recipes here on PWWB, like ahi poke bowls & beef stew, remind me of Mom’s side of the family. Loco moco, however, always makes me think of Dad. He’s a meat & potatoes Midwesterner who loves anything smothered in gravy, so the Hawaii drive-in scene really stole his heart when he lived in Honolulu with my mom. His reminiscing about their trips to Rainbow Drive-In has given me such a soft spot for classics like Loco Moco.

Loco moco is hearty, no-frills Hawaii comfort food, & this recipe is how we like to make it at home. It stays pretty true to classic versions you’ll find on the islands – a rich beef patty served over sticky white rice with glossy brown gravy & a fried egg. We amp our gravy up with lots of hearty mushrooms & sweet onions for extra flavor, tying all components of the dish together – truly the ultimate comfort food meal!

Non-locals & mainlanders might be surprised to learn that a wholesome, hearty dish like loco moco is so big in Hawaii. Truth is, there’s so much more to the local food culture than tropical flavors & amazing fresh fish. Influence from many Pacific Rim cultures makes comfort food a huge part of the Hawaii food scene & loco moco is the perfect example of that. It’s rich, hearty, & so satisfying – whether you enjoy it for breakfast, lunch, or dinner, loco moco is always a good idea!

What is Loco Moco?

Let’s take a few steps back. As iconic as Hawaiian loco moco is, if you’re a non-local it probably doesn’t match the vision of fresh seafood & tropical flavors often associated with Hawaii. The reality is that there’s so much more to the local Hawaii food scene. Hawaii is a melting pot of people, cultures, & traditions from all around the Pacific Rim & you can easily experience this diversity through Hawaii’s food. On the islands, you can eat everything from the freshest poke you’ve ever had to epic Hawaiian comfort food like noodles, fried chicken, & gravy-smothered loco moco. In Hawaii, the food is as culturally rich & diverse as the people!

So what is loco moco? ⇢ Loco moco is a classic local-style meal consisting of a burger patty served over rice, smothered with brown gravy, & topped with a fried egg. It’s a staple in the diner & drive-in scene in Hawaii but it’s so well-loved that you’ll also find high-end versions served at the islands’ fanciest brunch spots. Visitors & locals alike have a soft spot for this simple, humble dish.

Where did loco moco originate from? ⇢ Legend has it that loco moco was created in the 1940s in Hilo (on the Big Island) when teens were looking for a quick & cheap meal. A group of teenage boys called the Lincoln Wreckers played sports at Hilo High School & used to hang out at the Lincoln Grill restaurants afterward. They only had a few bucks to spare but wanted something filling & comforting. So they asked the owner, Nancy, to whip up the dish & a legend was created!

Loco moco has a strong resemblance to Japanese hambagu, a hamburger steak also served over rice. Like other uniquely local-style dishes like spam musubi & shoyu chicken, loco moso is a clear reflection of Pacific Rim cultures on the islands, whether the Lincoln Wreckers realized it or not.

What does loco moco mean? ⇢ According to legend, the first teenage boy brave enough to dig into this dish was nicknamed “Loco” (or “crazy”). Moco simply rhymed!

Key Ingredients

This is a classic loco moco recipe just like the versions my parents enjoyed at drive-ins when they were younger. It uses simple, no-fuss ingredients to create 4 hearty & delicious components that stack on top of each other for the perfect comforting bite.

Loco moco ingredients sit atop a grey tiled surface: ground beef, Worcestershire, onion powder, seasoned salt, black pepper, butter, mushrooms, sweet onion, beef stock, beef base, cornstarch, Calrose rice, eggs & green onions.

Note: Full ingredients list & measurements provided in the Recipe Card, below.

You need…

  • Burger patties – The loco moco burger patty is the core of the dish! We make ours from ground beef be sure to use 80% lean for tons of flavor. Worcestershire sauce adds umami-rich savoriness & seasonings like onion powder, black pepper, & seasoned salt like Lawry’s take all the flavors up a notch.
  • Gravy Smother the loco moco burger in a classic brown gravy made with butter, beef broth, beef base, Worcestershire sauce, & a cornstarch slurry. We also love to add sweet onions & mushrooms to our beef gravy for an even more delicious heartiness.
  • Rice Our preferred variety is Calrose rice, the medium-grain white rice often used in Hawaii. It gets nice & sticky as it cooks, creating the perfect bed to soak up all the richness of the loco moco burger & brown gravy. If you have trouble finding Calrose rice, a short-grain variety like sushi rice will work just fine. If you prefer to use something like brown rice or wild rice, go for it.
  • Egg Fry it sunny side up & place on top of your loco moco with a garnish of thinly sliced green onions.

How to Make Loco Moco

Loco moco was originally created to be quick & convenient, so this recipe stays true to that tradition! It all comes down to preparing 4 componentssticky white rice, beef burger patties, brown gravy, & fried eggs – then stacking them on top of each other. Making it all from scratch takes about 40 minutes, but a bit of meal prep makes this recipe even faster.

Full Recipe Directions, including step-by-step photos, are included in the Recipe Card, below.

1

Cook the rice. Be sure to rinse your rice thoroughly to remove any starches from the surface of the grain. This helps give the rice a beautifully sticky consistency! Transfer to a rice cooker & cook according to the manufacturer’s directions. Important! ⇢ For extra fluffy rice, be sure to let the rice rest in its steam for 5-10 minutes after it finishes cooking.

2

Pan-fry the hamburger patties. Gently mix all the burger ingredients with your hands & form into patties (don’t over mix or else the burgers may be tough!). Pan-fry the patties in butter until they’re golden brown. Why? ⇢ Pan-frying keeps all of the rich beef drippings in the pan. That’s exactly where we want them – they’re the foundation of flavor for the loco moco gravy!

3

Build the gravy. Add sliced mushrooms & sweet onions to the pan & sauté them for about 10 minutes until deeply browned (don’t rush this!). Deglaze with beef stock & scrape up all the browned bits from the bottom of the pan – there’s so much flavor trapped in this fond! Add Worcestershire sauce & beef base, then bring to a simmer & whisk in the cornstarch slurry. Why? ⇢ These gravy ingredients create tons of flavor but the cornstarch slurry is all about texture! It helps everything come together as a thick & glossy gravy.

4

Fry the eggs. You’re after a beautiful sunny side-up egg here! Simply crack an egg into melted butter & cook until the whites set but the yolk is still a little runny. Why? ⇢ A perfectly runny egg oozes into the rest of the loco moco as you slice into it – picture-perfect & so crave-worthy!

15-Minute Meal Prep

Doing a little bit of prep ahead of time helps everything come together even faster when you begin cooking. This is especially helpful if you’re making loco moco for a crowd! The burger patties are easy to mix & form ahead of time, then all you have to do is pop them in the pan. You can also slice all of the mushrooms & onions in advance to get the gravy going faster. Check the Recipe Notes, below, for more loco moco meal prep tips!

Loco Moco Assembly & Serving

The classic way to serve loco moco is by placing the juicy burger patty on top of the sticky rice & smothering it all with a big spoonful of rich beef gravy. It’s a genius way to layer things because the fluffy rice instantly soaks up all the gravy goodness & juices from the burger. 🤤 Place the fried egg on top & add some sliced green onion for a picture-perfect finishing touch.

Loco moco is a super filling lunch or dinner, but it’s also good for breakfast! (Throw an egg on anything & it counts as breakfast, right?! 😉). The best way to eat loco moco is to slice into the egg first, allowing the yolk to run through the gravy & rice. Mix it all together, dig in, & enjoy!

In Hawaii, you’ll find loco moco served plate lunch style with mac salad, but it’s also fantastic & filling enough all on its own. Feel free to share your serving with others!

  • 2 cups Calrose rice, rinsed well
  • loco moco burger patties, below
  • beef gravy, below
  • fried eggs, below
  • 2 green onions, thinly sliced

loco moco burger patties:

  • 1 tablespoon unsalted butter
  • 1 pound 80% lean ground beef
  • 1 large egg
  • 2 tablespoons panko breadcrumbs
  • 1 tablespoon Worcestershire sauce
  • ½ teaspoon seasoned salt, such as Lawry’s
  • ½ teaspoon onion powder
  • ¼ teaspoon ground black pepper

for the onion & mushroom beef gravy:

  • 1 tablespoon unsalted butter
  • 8 ounces white button or cremini (baby bella) mushrooms, cleaned, trimmed, & thinly sliced
  • 1 medium sweet onion, thinly sliced
  • 2 cups beef stock or broth
  • 2 teaspoons Worcestershire sauce

  • cornstarch slurry (1 scant tablespoon cornstarch whisked with 1 tablespoon water)

for the fried eggs:

  • 1 tablespoon unsalted butter
  • 4 large eggs
  • kosher salt & ground black pepper, to season

Instructions

  1. Cook the rice: Transfer the rice to the rice cooker’s inner cooking pan. To rinse the rice, cover the rice with warm water, give it a good jostle with your hands to agitate the dust off the rice’s surface, then carefully drain the water. Repeat rinsing until the water runs clear – this takes a good minute or two; be patient! Following the ratios provided in the manufacturer’s directions, add water to the inner cooking pan. Place the inner cooking pan in the rice cooker & cook according to the manufacturer’s directions. Once the rice is done, let it steam & rest for 5-10 minutes before serving.An overhead shot of perfectly cooked white rice for poke bowls rests inside of an open Zojirushi rice cooker.

  2. Form the loco moco burger patties: Preheat a large cast iron skillet over medium-high heat. Meanwhile, prep the burger patties. To a medium bowl, add the ground beef, egg, panko breadcrumbs, Worcestershire sauce, seasoned salt, onion powder, & ground black pepper. Use your hands to mix until just combined – take care not to overmix, as doing so leads to tough burgers. Divide the mixture into 4 equal portions. Form each portion into a ¾-inch thick burger patty, pressing a small indent in the center of each patty to prevent the burgers from swelling as they cook. Four raw beef patties, each with an indent in the middle, rest on a parchment paper-lined sheet pan atop a grey tiled surface.
  3. Pan-fry the loco moco burger patties: Add the butter to the hot cast iron skillet. Once melted, place the loco moco hamburger patties in the skillet. Cook 3 minutes per side, until a nice crust has formed on each side of the burgers. Transfer to a plate & set aside.Four cooked beef patties sit in a black cast-iron skillet atop a white-grey tiled surface.
  4. Prepare the onion & mushroom beef gravy: Add the butter to the same skillet used to pan-fry the burgers. Once melted, add the mushrooms & onion. Cook, stirring occasionally, until tender & browned, 8-10 minutes. Deglaze the skillet with beef stock, using a wooden spoon to scrape up any browned bits from the bottom of the pan, then stir in the Worcestershire sauce, & beef base. Bring the mixture to a simmer. Once simmering, stir in the cornstarch slurry – the gravy should thicken immediately. Tate & adjust seasoning as desired. Reduce heat to keep warm for serving.A black cast-iron pan with loco moco gravy and a wooden spoon sits atop a white-grey tiled surface.
  5. Prepare the fried eggs: Meanwhile, as you prep & simmer the gravy, prepare the fried eggs. Place the butter in a large nonstick skillet over medium heat. Once the butter is melted, carefully crack the eggs into the pan. Season with a good pinch of kosher salt & ground black pepper as desired. Cook 3-4 minutes, until the whites are set. Set aside for servingFour sunny-side-up fried eggs sit in a black skillet with a gold handle atop a white-grey tiled surface.
  6. Loco moco assembly & serving: Pile the rice on a plate or shallow bowl, creating a nice bed for the burger. Place the loco moco hamburger on top of the rice. Smother the burger with onion & mushroom gravy, then top with a fried egg. Finish with a sprinkling of thinly sliced green onion, shoyu (soy sauce), & any other condiments you love. Serve immediately.

    This was my husband’s favorite dish when we visited the Big Island. I made it today for his birthday, and it was a big hit. The mushroom onion gravy sauce was everyone’s favorite part (I used dried porcini mushrooms that I rehydrated and used the water for the beef base water). Thank you for this recipe! We will definitely make this again.
