Hamburger Steak Recipe — Hawaii's Plate-Lunch Brown-Gravy Classic

Ingredients

Method

1. Mix the patty. In a large bowl, combine the ground beef with the grated onion, egg, panko, shoyu, garlic, pepper, and salt. Mix gently with your hands until the seasonings are evenly distributed. Don't overwork it. The more you compress the meat, the tougher the patty gets. Divide into 4 equal portions and shape into ovals about 3/4 inch thick.
2. Sear the patties. Heat the skillet over medium-high heat until it's just beginning to smoke. Add the patties. No oil. The beef will render its own fat. Don't move them for 4 minutes. Flip and sear the other side for 3 more minutes. The center can still be a little pink. The patties finish cooking in the gravy. Transfer to a plate.
3. Caramelize the onions. Reduce the heat to medium. Add the butter to the skillet along with the beef drippings already there. Add the sliced onions and a pinch of salt and cook, stirring every couple of minutes, until they are deep gold and starting to caramelize at the edges, 12 to 15 minutes. Don't rush this step. The brown color of the gravy comes from the brown of the onions.
4. Build the gravy. Sprinkle the flour over the cooked onions and stir for 2 minutes until you can no longer see dry flour and the bottom of the pan looks lightly browned. Pour in the beef stock in three additions, stirring after each so the flour doesn't lump. Add the shoyu, Worcestershire, and black pepper. Bring to a gentle simmer.
5. Finish in the gravy. Nestle the seared patties back into the simmering gravy along with any juices on the plate. Lower the heat, cover, and simmer for 8 to 10 minutes until the patties hit 160F and the gravy thickens to coat the back of a spoon. Taste and adjust salt and pepper.
6. Plate, lunch-counter style. Put two scoops of hot rice on one side of each plate and a scoop of cold mac salad on the other. Lay a patty between them and ladle the brown onion gravy generously over the patty AND the rice. The rice has to swim in the gravy. That is the plate-lunch rule.

Notes from a local cook

Grate the onion, don't chop it. Grated onion releases its juice into the meat and disappears into the patty texture. Chopped onion turns into chewy lumps you can taste. This one swap separates a soft local-style hamburger steak from a dense backyard hamburger.

Reuse the fond. The dark crusty bits stuck to the pan after you sear the patties are the entire flavor of the gravy. Do not wipe them out. The flour and stock will lift them off and dissolve them into the sauce as you stir.

Make extra gravy. The single biggest reason a Hawaii diner's hamburger steak tastes better than yours: they are not stingy with the gravy. Plan to make at least 3 cups for 4 patties. Better still, double it. Leftover gravy keeps for four days in the fridge and reheats into a quick loco moco the next morning. Rice in a bowl, patty on top, gravy over it, fried egg, done.

The mac salad is part of the dish. Hawaii plate-lunch mac salad is mayo-heavy, slightly sweet, and served cold. It is the cooling counterpoint to the hot peppery gravy and it belongs on the plate. Use our local-style macaroni salad recipe to round out the plate.

A little background

Hamburger steak is older than loco moco and built the same way. Richard and Nancy Inouye invented loco moco in 1949 at the Lincoln Grill in Hilo, scooping rice into a bowl, dropping a hamburger patty on top, and ladling gravy over the whole thing for a group of local teenagers. The fried egg came later. What sat under that egg the whole time is a hamburger steak. The plate-lunch version is the older parent. Same gravy, same patty, served flat on the plate next to rice and mac salad instead of bowled.
