This one-pot meal is inspired by the Japanese steak chain Pepper Lunch—except it’s made much easier in a rice cooker! The combination of marinated beef, butter, onion, and corn is one that can never go wrong, so try this recipe for your next weeknight dinner.
What Makes This Recipe Special?
The beauty of this recipe lies in its simplicity. By marinating thinly sliced beef in a flavorful mix of soy sauces, oyster sauce, sesame oil, and garlic, you get a rich umami flavor without hours of prep time. Everything comes together seamlessly in the rice cooker, so you can set it and forget it!
Ingredients You’ll Need:
- Jasmine Rice: A fragrant, sticky rice that pairs perfectly with savory dishes.
- Shabu Shabu Beef: Thinly sliced beef that cooks quickly and absorbs all the delicious marinades.
- Onion & Corn: For sweetness and texture that complement the savory beef.
- Butter & Green Onion: For a rich finish and a pop of color.
The Marinade That Makes the Difference
The marinade is key to infusing the beef with deep flavors. Light soy sauce adds saltiness, dark soy sauce provides color and richness, while oyster sauce adds a savory kick. A splash of rice wine and a bit of sugar round out the profile, making each bite irresistibly delicious.

How to Make Rice Cooker Beef Pepper Rice
- Prepare the Beef: Start by marinating your beef for at least 20 minutes. The longer it marinates, the deeper the flavors will soak in, but if you’re short on time, even a quick marinate works wonders!
- Set Up Your Rice Cooker: Add your rinsed jasmine rice to the rice cooker, followed by the marinated beef, onion, and sweet corn. Add water and cook using the white rice setting.
- Finish with Butter & Garnish: Once cooked, stir in a tablespoon of butter for richness. Garnish with chopped green onion and a sprinkle of black pepper for the perfect finish.
Why Use a Rice Cooker?
A rice cooker isn’t just for cooking rice—it’s a great tool for making one-pot meals like this! The heat distribution ensures the beef cooks evenly while the rice absorbs all the flavors, creating a deliciously integrated dish. Plus, it’s super easy to clean up afterward!
However, if you want a stovetop version where you can stir-fry the ingredients for maximum flavor, you can check out my one-pan Beef Pepper Rice recipe here. I promise it’s just as easy to make!

User Reviews
Super yum! 10/10
Thanks, glad to know you liked it!
Added a splash of mirin, dash of white pepper and corn flour to the marinade and used pork shabu shabu slices instead.
Added edamame along with frozen corn too. For tastier rice, i substituted 2 tbsp of tsuyu (japanese concentrated soup stock from mart) of the water to cook rice. 2.25 rice cups for 6 pax. Always falling back on this recipe on lazy weekends. Thank you!
Happy you liked it, and your upgrades sound super tasty!
This was sooooo good. Used 200gr minced beef, bcs that’s all what I had and only adjusted the marinade. Recipe is a real winner, we liked it a lot
So glad you liked it!
Easy to cook for the small family esp for kids who are fussy
Thanks for your review! This is definitely a kid-friendly recipe 🙂
Are you using the rice measuring cup or a standard measuring cup for the jasmine rice for this recipe? Thanks!
I use the standard measuring cup! But if you don’t eat a lot of rice, you can go with the rice measuring cup (just note it might be a bit more flavorful because a rice cup is usually much smaller, around 160ml)
What size rice cooker do you use? Thanks!
Hi, mine holds up to 1L or 5 cups. But smaller/bigger rice cookers should work just fine. 🙂
