Authentic Loco Moco Recipe with Onion Gravy and Fried Egg
This classic loco moco recipe features a seasoned beef patty, rich brown onion gravy, and a runny fried egg over white rice. The ultimate Hawaiian comfort food.
If you are looking for the ultimate comfort meal, this authentic loco moco recipe delivers a hit of savory, salty, and rich flavors in every bite. Originally a staple of Hawaiian diners, this dish is the quintessential island soul food that bridges the gap between breakfast and dinner.
The architecture of a great Hawaiian loco moco is simple but precise: a foundation of hot, sticky white rice topped with a thick hamburger steak with egg and gravy. The magic happens when the liquid gold of a runny yolk breaks, merging with a glossy, onion-spiked brown sauce to coat the seasoned beef.
While many versions use a powdered packet for the sauce, we are deglazing the pan with beef stock and Worcestershire to build a deeper flavor profile. This is a stick-to-your-ribs meal that proves why simple ingredients, when stacked correctly, become legendary.
Ingredients
The Beef Patties
- 1 lb (450g) ground beef, 80/20 lean-to-fat ratio
- 1/2 teaspoon garlic powder
- 1/2 teaspoon onion powder
- 1 teaspoon Worcestershire sauce
- Kosher salt and freshly cracked black pepper to taste
- 1 tablespoon neutral oil (vegetable or canola)
Brown Onion Gravy
- 1 small yellow onion, thinly sliced into half-moons
- 2 tablespoons unsalted butter
- 2 tablespoons all-purpose flour
- 1 1/2 cups (355ml) beef broth, low sodium
- 1 tablespoon Worcestershire sauce
- 1 teaspoon soy sauce
- Black pepper to taste
For Serving
- 4 cups cooked short-grain white rice, hot
- 4 large eggs
- Sliced green onions for garnish
Instructions
- 1
Mix the ground beef with garlic powder, onion powder, 1 teaspoon Worcestershire sauce, salt, and pepper in a bowl until just combined; do not overwork the meat.
- 2
Form the beef into 4 equal-sized patties, about 3/4-inch thick, and use your thumb to make a slight indentation in the center of each to prevent bulging.
- 3
Heat oil in a large cast-iron skillet over medium-high heat until shimmering, then sear the patties for 4-5 minutes per side until a dark crust forms and they reach your desired doneness.
- 4
Remove the patties from the skillet and set aside on a plate, leaving about 1 tablespoon of rendered fat in the pan.
- 5
Reduce heat to medium and add the sliced onions and butter to the skillet, sautéing for 5-6 minutes until the onions are soft and golden brown.
- 6
Sprinkle the flour over the onions and stir constantly for 1-2 minutes to cook out the raw flour taste, creating a light brown roux.
- 7
Slowly whisk in the beef broth, Worcestershire sauce, and soy sauce, scraping the bottom of the pan to release all the browned bits (fond).
- 8
Simmer the gravy for 3-5 minutes until thickened to a glossy consistency that coats the back of a spoon; season with extra pepper if needed.
- 9
Fry the eggs in a separate non-stick skillet with a touch of butter, aiming for a 'sunny-side up' finish where the whites are set but the yolks remain completely fluid.
- 10
Assemble the bowls by scooping a generous portion of hot rice into each, topping with a beef patty, smothering with the hot onion gravy, and crowning with a fried egg.
- 11
Garnish with sliced green onions and serve immediately while the gravy is piping hot.

Tips
- → Use 80/20 beef. The fat content is essential for a juicy patty and provides the base flavor for the gravy roux.
- → Don't skip the rice prep. Use a short-grain or medium-grain 'sticky' rice (like Calrose) for the most authentic island texture.
- → Control the salt. Since beef broth and soy sauce are both salty, wait until the gravy has thickened before adding any additional salt.
- → Keep the rice hot. The heat from the rice helps keep the bottom of the patty warm while you finish the eggs.
FAQ
What kind of rice is best for loco moco?
Authentic Hawaiian loco moco is always served with white, short-grain or medium-grain steamed rice. Avoid long-grain varieties like Basmati, as they are too fluffy and won't hold up under the heavy gravy.
How do I make the gravy darker?
To achieve a deep brown color, ensure you sear the beef patties thoroughly to leave behind dark fond, and allow your flour and butter roux to cook until it reaches a peanut butter color before adding the liquid.
Can I make this with a different protein?
Yes, while the beef patty is standard, variations include using Spam, teriyaki chicken, or even kalua pork, though the beef patty remains the most traditional version.
Why does my gravy have lumps?
Lumps usually form when liquid is added too quickly to the roux. Whisk in the beef broth one splash at a time at the beginning, creating a paste before thinning it out into a sauce.
