What Is Loco Moco?
Loco moco is a savory rice bowl built around four key elements:
- A foundation of steamed white rice
- A seasoned hamburger patty (occasionally swapped for alternatives like fried chicken, teriyaki beef, or Spam)
- Brown gravy (sometimes with mushrooms or onions)
- A just-cooked fried egg, typically sunny side up or over easy
The result is a crave-worthy, deeply satisfying meal commonly enjoyed for breakfast, lunch, or dinner—whenever hearty comfort food calls.
Loco Moco Origins and History
Like many iconic Hawaiian foods, loco moco tells a story of humble beginnings, resourcefulness, and cultural intermingling. The dish was created in Hilo, on Hawaii’s Big Island, in the late 1940s at the Lincoln Grill diner. According to legend, a group of local teenagers from the Lincoln Wreckers Sports Club asked the owners, Richard and Nancy Inouye, for something cheap, quick, and filling, different from the usual sandwich or American fare. The answer was a scoop of rice, topped with a hamburger patty, and covered in brown gravy. The fried egg was added shortly after. The quirky name—”loco moco”—was invented on the spot, a playful fusion of the Spanish word for “crazy” and a rhyming flourish.
Loco Moco as Hawaiian Plate Lunch
Loco moco perfectly embodies the spirit of the Hawaiian plate lunch: an all-in-one meal bringing together diverse immigrant influences. The dish combines American hamburger traditions, Japanese and Chinese staples like rice, and a pan-Asian love for rich gravies. It’s an example of Hawaii’s multicultural foodways and the ingenuity of local cooks making the most with limited means.
Essential Loco Moco Ingredients
One beauty of loco moco is its accessibility: you can make it with ingredients common to most kitchens, and each household adds its own flair. Here’s a breakdown of the basics and suggested add-ons:
- Rice: Short-grain or medium-grain white rice is preferred for its stickiness, but any steamed rice works.
- Beef Patty: Seasoned ground beef, shaped thick so it stays juicy.
- Gravy: A classic brown gravy made from beef stock, sometimes with mushrooms and onions for added depth.
- Egg: Fried sunny-side up or over easy, ensuring a runny yolk soaks into the rice below.
- Garnish (optional): Sliced green onions, fried crispy onions, or even a dash of chili pepper water or hot sauce.

2. Shape and Cook the Beef Patties
- In a mixing bowl, combine ground beef, minced onion, garlic, soy sauce, Worcestershire, salt, and pepper.
- Gently mix together until just incorporated. Do not over-mix.
- Form into 4 large, thick patties (about 3/4 inch thick). Make a small indentation in the center to prevent puffing during cooking.
- Heat oil in skillet over medium-high heat.
- Add patties and cook until deeply browned and just cooked through, about 3–4 minutes per side.
- Transfer to plate and keep warm. Drain excess fat, reserving about 1 tablespoon in the pan for gravy.
3. Make the Brown Gravy
- Add sliced mushrooms to the same skillet (if using) and cook until browned, about 3 minutes.
- Stir in flour and cook, stirring, for 1 minute to make a roux. The mixture will become pasty and lightly golden.
- Gradually whisk in beef stock, scraping up any fond (browned bits) from the pan’s bottom.
- Season with additional soy sauce and Worcestershire, and add black pepper to taste.
- Simmer until thickened to a pourable gravy, about 3–4 minutes.
- Return cooked patties to the pan to quickly warm through in the gravy, then set aside.
4. Fry the Eggs
- In a clean skillet, heat a little oil or butter over medium heat.
- Crack eggs and fry until whites are set but yolks remain runny (sunny side up or over easy).
- Season with salt and pepper.
5. Assemble the Loco Moco
- Scoop a generous portion of hot steamed rice into a shallow bowl or plate.
- Top with one beef patty.
- Ladle a hearty portion of brown gravy over the patty and rice.
- Set a fried egg on top, letting the yolk just begin to mingle with the gravy below.
- Garnish with sliced green onions if desired. Serve immediately, inviting diners to break the yolk and mix everything together.
Expert Tips for the Best Loco Moco
- Use day-old rice for the best texture—it’s slightly drier and soaks up gravy beautifully.
- Don’t overwork the beef mixture; gentle mixing keeps patties tender.
- Let your beef patties rest after cooking so juices redistribute.
- Whisk gravy constantly to avoid lumps. If the gravy is too thick, add extra stock; if too thin, keep simmering or add a cornstarch slurry.
- Mushrooms and caramelized onions add extra depth, but aren’t mandatory.
Popular Loco Moco Variations
- Chicken Katsu Loco Moco: Swap the beef patty for a crispy breaded chicken cutlet.
- Spam Loco Moco: A beloved Hawaiian twist using slices of grilled Spam in place of hamburger.
- Fish Loco Moco: Use grilled fish, such as mahimahi, for a lighter version.
- Vegan Loco Moco: Use a plant-based patty and vegan gravy; top with a tofu “egg” or sauteed mushrooms.
- Loaded Loco Moco: Add macaroni salad, kimchi, or pickled vegetables on the side for the full Hawaiian plate lunch experience.

Frequently Asked Questions (FAQs)
Can I make loco moco ahead of time?

Can I freeze loco moco components?
Beef patties and gravy freeze well for up to 2 months. Thaw and reheat gently. Rice and eggs are best prepared fresh, as freezing can change their textures.
How can I make this dish gluten free?
Use gluten-free soy sauce (tamari) and thicken the gravy with cornstarch or a gluten-free flour blend.
Is there a healthier version of loco moco?
Absolutely! Use leaner ground beef or ground turkey, brown rice or cauliflower rice, and top with a poached egg instead of a fried egg. You can also add sautéed greens.
