A beloved Hawaiian plate-lunch classic born on the Big Island in the 1940s, the Loco Moco stacks steaming white rice, a juicy seasoned beef patty, rich beef gravy, and a sunny-side-up fried egg with a runny yolk. Each bite combines savory beef, silky egg, salty gravy, and tender rice into pure island comfort food.

Ingredients
For the rice
- 2 cups uncooked short-grain white rice
- 3 cups water
- 1/2 teaspoon kosher salt
For the beef patties
- 1 1/2 lbs ground beef (80/20)
- 1 teaspoon kosher salt
- 1/2 teaspoon freshly ground black pepper
- 1/2 teaspoon garlic powder
- 1 tablespoon neutral oil
For the brown gravy
- 2 tablespoons unsalted butter
- 1 small yellow onion, finely diced
- 8 ounces cremini mushrooms, sliced (optional)
- 2 tablespoons all-purpose flour
- 2 cups beef broth
- 1 tablespoon Worcestershire sauce
- 1 teaspoon soy sauce
- Salt and black pepper to taste
For the eggs and garnish
- 4 large eggs
- 1 tablespoon unsalted butter
- 2 green onions, thinly sliced
- Shredded lettuce or steamed white rice, for serving
Directions
- Rinse the rice under cool water until clear, then combine with the 3 cups water and salt in a saucepan. Bring to a boil, cover, reduce heat to low, and simmer 18 minutes. Remove from heat and let rest, covered, 5 minutes, then fluff with a fork.
- Meanwhile, divide the ground beef into 4 equal portions (about 6 oz each) and gently shape into patties slightly wider than your bun (they will shrink). Season both sides with salt, pepper, and garlic powder; do not overwork the meat.
- Heat the oil in a large cast-iron skillet over medium-high heat. Sear the patties 3 to 4 minutes per side for medium, until a deep brown crust forms. Transfer to a plate and tent loosely with foil.
- Drain all but 1 tablespoon of fat from the skillet, then melt the butter over medium heat. Add the onion and mushrooms (if using) and cook 5 to 6 minutes until softened and lightly browned. Sprinkle in the flour and stir 1 minute to cook off the raw taste.
- Slowly whisk in the beef broth, Worcestershire, and soy sauce, scraping up the browned bits from the pan. Simmer 3 to 4 minutes until thickened to a pourable gravy consistency. Season with salt and pepper, then return the patties (and any juices) to the skillet to warm through.
- While the gravy finishes, melt the butter in a nonstick skillet over medium-low heat. Crack the eggs in one at a time and cook 3 to 4 minutes until the whites are set and the edges are crisp, but the yolks remain runny. Season lightly with salt.
- To plate, mound about 3/4 cup of rice on each of 4 shallow bowls. Set a beef patty on top, spoon a generous amount of gravy over the patty, and finish with a fried egg. Garnish with sliced green onions.
- Serve immediately while the yolk is still runny so it can be broken and mixed into the rice and gravy at the table.
Cook’s Notes
- Use short-grain or medium-grain Calrose rice for the authentic sticky texture; long-grain rice will not clump properly under the gravy.
- Gently form the patties without compressing the meat too tightly, and never press them with a spatula while cooking, or they will lose their juices.
- A runny yolk is essential; aim for whites that are fully set but yolks that jiggle when the plate is moved.
- For a richer gravy, deglaze the patty skillet with 2 tablespoons of red wine before adding the broth.
- Traditional diners sometimes add a scoop of macaroni salad alongside the loco moco for a true plate-lunch experience.
