Ingredients
- 1 cup white rice
- 200 g fatty beef slices
- 12 onion
- 1 tbsp vegetable oil
- to taste salt
- 1 tbsp light soy sauce
- 0.5 tbsp dark soy sauce
- 1 tbsp oyster sauce
- 1 tbsp honey
- 1 tsp cornstarch
- to taste black pepper
- 2 slices processed cheese
- 1 egg
- optional white sesame seeds
- optional dried parsley
Instructions
- 1Soak the rice

Begin by placing raw white rice into a bowl and pouring in warm water. Let the rice soak thoroughly; this step ensures the grains soften properly so they cook evenly in the microwave later.
Tip: Soaking the rice for at least 10 minutes helps achieve a fluffier texture once it is cooked. - 2Microwave the onion base

Place the sliced onions in the microwave for two minutes until they become soft and translucent. This initial heating prepares the base for the beef and sauce layers.
Tip: Spreading the onions in an even layer ensures they soften consistently during the microwave cycle. - 3Scald the fatty beef

Place the thinly sliced fatty beef into a bowl and pour boiling water over it from a kettle. This quick scalding process cleans the meat and removes any impurities before it is added to the rest of the dish.
Tip: A very brief soak is all you need—the goal is to clean the meat without fully cooking it yet. - 4Mix the sauce ingredients

In a glass measuring cup, combine light soy sauce, dark soy sauce, and oyster sauce. Add a spoonful of honey along with black pepper and starch to create a balanced savory-sweet sauce base.
Tip: Honey provides a nice glossy finish to the beef once it is cooked in the microwave. - 5Complete the sauce

Add an appropriate amount of warm water to the measuring cup containing the sauces and honey. Mix everything well until the honey and starch are fully dissolved into a smooth, savory liquid.
Tip: Using warm water helps the honey and starch integrate more easily than cold water. - 6Combine beef and onions

Use chopsticks to transfer the blanched beef slices into the bowl with the onions that have already been microwaved. Spread the beef evenly over the top in preparation for adding the sauce.
Tip: Spreading the meat out helps it cook more evenly when you return the bowl to the microwave. - 7Add the savory sauce

Pour the prepared mixture of light soy sauce, dark soy sauce, oyster sauce, honey, and black pepper over the bowl of parboiled beef and onions. This rich, multi-layered sauce is the key to flavoring the dish while it cooks in the microwave.
Tip: Distribute the sauce evenly across the meat to ensure every bite is well-seasoned and to keep the beef moist during microwaving. - 8Layer with cheese

Place two square slices of processed yellow cheese directly over the beef and sauce. As the bowl heats up, the cheese will melt into the sauce, creating a creamy and indulgent glaze that pairs perfectly with the savory beef.
Tip: For the best melt, use standard processed cheese slices or a mild cheddar that liquefies easily under microwave heat. - 9Add egg and cook

Crack a fresh egg over the beef and cheese then microwave the entire bowl for two minutes. This poaches the egg and transforms the cheese into a rich melted glaze.
Tip: Gently piercing the yolk with a toothpick allows steam to escape and prevents the egg from popping while heating. - 10Microwave the rice

Transfer the bowl of rice, which has been soaking in warm water, into the microwave. Cook on high power for ten minutes. Pre-soaking the rice is a vital step that ensures the grains become fluffy and fully cooked in the microwave.
Tip: Make sure the water level is about half an inch above the rice before starting the microwave to prevent the top layer from drying out. - 11Garnish and serve

Finish the dish by sprinkling a handful of white sesame seeds and dried parsley flakes over the top. This final touch adds a pleasant nutty aroma and a pop of green color to your homemade microwave beef bowl.
Tip: Serve the bowl immediately while the cheese is still gooey and the egg yolk is warm for the best flavor profile.
