Introduction

Beef Gyudon made easy with a rice cooker is the perfect lazy dinner that comes together in just 20 minutes. This comforting Japanese dish features tender beef and onions simmered in a savory sauce, cooked right with the rice for an effortless meal.

A white bowl filled with a base layer of light brown cooked rice mixed with translucent noodles, creating a textured and intertwined foundation. On top of the rice and noodles, there are tender, brown cooked beef slices arranged around the middle. Centered over the beef are two soft-poached eggs with smooth, glossy white surfaces and slightly runny yolks just visible beneath, sprinkled with bright orange-red seasoning and small black sesame seeds. The dish is finished with small pieces of fresh green chopped chives scattered over the top, all set against a white marbled texture background. photo taken with an iphone --ar 4:5 --v 7

Ingredients

2 cups rice (rinsed)
200 g thinly sliced beef (shabu-shabu or hot pot beef)
1/2 onion (thinly sliced)
1-1/4 cups water
1/2 cup dashi liquid concentrate (or instant dashi mixed as directed)
1/4 cup soy sauce
4 tbsp mirin
Salt and pepper (to taste)
Optional toppings: chopped green onions, pickled ginger (beni shoga), or onsen eggs

Instructions

Step 1: Rinse the rice under cold water until the water runs clear to remove excess starch, then add it to the rice cooker pot.
Step 2: Layer the thinly sliced onion evenly over the rice without mixing.
Step 3: Lay the thin beef slices on top of the onions, keeping the layers intact.
Step 4: In a bowl, whisk together the water, dashi concentrate, soy sauce, mirin, salt, and pepper until well combined.
Step 5: Pour the sauce evenly over the beef and rice layers in the rice cooker.
Step 6: Close the rice cooker lid and press the Cook button to start cooking.
Step 7: When the rice cooker finishes, open the lid and gently fluff everything together to combine the flavors.
Step 8 (optional): To serve with onsen eggs, boil water and add 2/3 cup of cold water, then remove from heat. Carefully place eggs into the water and let them cook for 18 minutes before peeling and serving on the gyudon.

Tips & Variations

Use thinly sliced beef designed for hot pot for the most tender results that cook quickly.
Adjust the soy sauce and mirin to taste for a sweeter or saltier flavor.
Add a splash of sake to the sauce for extra depth.
Top with pickled ginger and chopped green onions for authenticity and brightness.
If you don’t have a rice cooker, you can make this in a covered pot on the stove using low heat and careful timing.

Storage

Store leftover gyudon in an airtight container in the refrigerator for up to 2 days. Reheat gently in a microwave or on the stovetop with a splash of water to prevent drying out. This dish is best enjoyed fresh but still delicious reheated.
