Ingredients
- 200 g marbled beef
- 1 whole white onion
- 15 g butter
- 2 tbsp black pepper sauce
- 1 bowl steamed white rice
Instructions
- 1Cut the white onion

Place a white onion on the black cutting board and slice it cleanly into thin strips.
Tip: Keep your fingers curled inward to safely guide the knife while slicing. - 2Transfer the onions

Gather the freshly sliced white onion strips and carefully place them into a clean glass bowl for later use.
Tip: Using a wide bowl makes it easier to grab handfuls of onions when it is time to cook. - 3Slice the Marbled Beef

Take the strips of marbled beef and place them onto a clean cutting board. Using a sharp knife, slice the beef into smaller, bite-sized strips so that they cook evenly and are easy to eat with rice.
Tip: Slicing slightly firmer or partially thawed beef makes it much easier to cut into uniform bite-sized strips. - 4Melt butter in the pan

Place a pat of butter into a non-stick pan set over medium heat and allow it to melt completely.
Tip: Watch the heat closely so the butter melts and foams without burning. - 5Sauté the onions

Add the freshly sliced onions directly into the pan containing the melted butter, tossing them to coat evenly.
Tip: Cook the onions until they soften and turn translucent to build a sweet base flavor. - 6Add the sliced beef

Place the sliced beef pieces directly into the pan on top of the sautéed onions.
Tip: Spread the beef out evenly to ensure it cooks uniformly alongside the onions. - 7Add Sauce to Beef and Onions

Pour a savory dark sauce, such as black pepper sauce, directly over the cooking beef and sliced onions in the pan. Toss everything together to ensure the sauce coats the ingredients completely.
Tip: Add the sauce gradually so you can easily control the richness and flavor intensity to your preference. - 8Assemble the Rice Bowl

Using a pair of chopsticks, pick up portions of the freshly cooked beef and onion mixture and arrange them neatly over a warm bowl of fluffy white rice.
Tip: Layer the beef and onions nicely over the rice so the flavorful sauce can soak slightly into the top grains.
