Slow-Cooker Japanese Gyudon Beef Rice Bowls Step-by-step instructions

Before you start

Before you start, ensure your beef is sliced as thinly as possible to ensure even cooking. Wash your onions thoroughly and remove the papery skins before slicing them into uniform strips.

Have your dashi, mirin, and soy sauce measured out in a small pitcher so they are ready to pour over the layered ingredients. If you are serving with fresh egg yolks, ensure they are kept chilled until the very last moment before serving to maintain their integrity and freshness.

Instructions

Preparation and layering

1. 1Layering the ingredients
   Place the thinly sliced onions at the bottom of the slow cooker. Layer the thinly shaved ribeye evenly over the onions. Combine the dashi broth, mirin, soy sauce, and grated ginger in a small bowl, then pour the mixture over the beef and onions.
   Look for Ensure the liquid covers the meat and onions partially.
   Tip Slice the onions thinly to ensure they soften perfectly during the long cooking process.

At this stage, the slow cooker should be neatly layered with onions at the bottom and beef on top. The liquid mixture should be poured evenly over the beef, just touching the bottom layers. Ensure there is enough space in the cooker so the ingredients are not packed too tightly, which allows the steam to circulate and cook everything evenly throughout the four-hour duration.

Slow cooking process

2. 2Slow cooking the beef
   Cover the slow cooker and set it to cook on LOW for 4 hours. Ensure the beef reaches an internal temperature of at least 145°F (63°C) and let the meat rest at least 3 minutes before serving to ensure it is thoroughly cooked through and safe to eat.
   Look for The onions should be translucent and amber-colored.
   Safe temperature 145°F (63°C) internal temperature (steaks, chops and roasts)
   Tip Do not lift the lid during the first few hours to maintain a consistent temperature.

During the cooking phase, the slow cooker will emit a savory, sweet aroma of soy sauce, ginger, and caramelized onions. The beef will shrink slightly and darken as it absorbs the dashi-mirin broth.

Check the cooker periodically through the glass lid to ensure the liquid is simmering gently, but avoid opening the lid, as this releases heat and moisture that are crucial for the tenderizing process.

Final assembly

3. 3Final assembly
   Prepare six bowls with a base of hot Japanese rice. Pile the cooked beef and onions on top of the rice. Carefully place one egg yolk in the center of each bowl and garnish with a portion of pickled ginger.
   Look for The beef should be tender and the sauce savory.
   Safe temperature 160°F (71°C) internal temperature (egg dishes)
   Tip Drizzle a little of the cooking broth over the rice before adding the beef for extra flavor.

Once the cooking is complete, the beef and onions should be glistening and coated in a reduced, flavorful sauce. The rice should be steaming hot and ready to absorb the juices. When assembling the bowls, ensure the egg yolk is added last so it stays intact, creating a rich, creamy sauce when it is broken and stirred into the hot beef and rice by the diner.

Common mistakes

A common mistake is using beef that is sliced too thick, which results in a chewy texture that does not soak up the sauce. Another error is failing to layer the onions at the bottom; if the onions are on top, they will not soften properly.

Finally, avoid over-salting the dish. The soy sauce and dashi already contain salt, so it is best to taste the sauce only after the cooking process is complete and adjust if necessary, rather than adding extra salt at the beginning.

How to tell it’s done

The dish is done when the onions are translucent and have turned a deep amber color, indicating they have fully caramelized in the sauce. The ribeye should be tender and easily pierced with a fork.

Using a meat thermometer, ensure the beef has reached an internal temperature of at least 145°F (63°C). Because the beef is thinly sliced, it will be cooked through well before the 4-hour mark, but the extra time is needed for the onions to reach the desired consistency.

• Steaks, chops and roasts: 145°F (63°C) in the thickest part, then a 3-minute rest
• Egg dishes: 160°F (71°C) in the thickest part
