As we dive into the creation of Japanese butter rice, let’s gather the ingredients. This recipe focuses on simplicity and quality, ensuring each component brings its best flavor to the dish.

For the Rice

  • 2 cups sushi rice or short-grain rice
  • 2 1/2 cups water
  • 1 tablespoon sake (optional, for added flavor)
  • 2 tablespoons unsalted butter
  • 2 teaspoons soy sauce
  • 1 sheet nori (seaweed), cut into small strips
  • Salt to taste (preferably flaky sea salt)
  • Optional garnishes: sesame seeds, chopped scallions, or furikake (Japanese rice seasoning)

Necessary Equipment

To embark on the adventure of making Japanese butter rice, it’s essential to have the right tools on hand. Just as the ingredients are few but carefully chosen, the equipment needed is minimal but crucial for achieving that perfect blend of flavors and textures. Let’s make sure your kitchen is equipped with the following items to bring this comforting dish to life.

Rice Cooker

A rice cooker is indispensable for achieving perfect, fluffy rice, which serves as the foundation of the Japanese butter rice. It ensures even cooking without the need for constant supervision, allowing the rice to emerge as the ideal canvas for the rich flavors we’ll be adding.

Non-Stick Skillet

For sautéing the rice with butter, soy sauce, and the addition of seaweed and other optional ingredients, a non-stick skillet is your best friend. It ensures that none of those precious grains stick or burn as they are imbued with the delightful flavors of the condiments.

Wooden Spoon or Spatula

A wooden spoon or spatula is necessary for gently mixing the rice, ensuring even distribution of butter and soy sauce without breaking the tender grains. Their gentle touch is key in preserving the integrity of each grain while achieving a homogenous flavor profile.

Measuring Cups and Spoons

Accuracy is crucial when it comes to the simplicity of Japanese butter rice. Measuring cups and spoons will help you add the precise amount of water for cooking the rice and the exact ratios of butter and soy sauce needed to create that perfect symphony of flavors.

Serving Bowl

Finally, a beautiful serving bowl enhances the experience of enjoying Japanese butter rice. Whether you choose something traditional or with a modern twist, the dish becomes even more inviting when presented with care and intention.

Armed with these essential pieces of equipment, we’re ready to dive into the cooking process. Let’s move forward and turn our carefully selected ingredients into a comforting, flavorful dish that highlights the elegance of Japanese cuisine.

Prep Work

Getting ready to make Japanese butter rice involves a few key steps that will ensure our dish turns out flavorful and perfect in texture. Let’s get everything prepped!

Washing and Soaking the Rice

The first step is to wash the rice thoroughly. We’ll need 2 cups of short-grain Japanese rice for this recipe. To wash, place the rice in a large bowl and cover it with cold water. Gently agitate the grains with your hands, then drain. Repeat this process 3-4 times, until the water runs clear. This removes excess starch, preventing the rice from becoming too sticky after cooking.

Once washed, soak the rice in fresh water for at least 30 minutes. This step is pivotal because it allows the grains to absorb water, ensuring they cook evenly and become perfectly tender. After soaking, drain the rice well before moving on to the next steps.

Preparing Additional Ingredients

While the rice is soaking, we have plenty of time to prepare the rest of our ingredients for the Japanese butter rice. You’ll need the following:

  • 3 tablespoons of unsalted butter
  • 1 small onion, finely chopped
  • 2 cloves of garlic, minced
  • Salt to taste
  • 2 1/2 cups of chicken or vegetable broth
  • Freshly ground black pepper
  • Chopped fresh parsley or chives for garnish (optional)

Let’s start by finely chopping the onion and mincing the garlic. These will be sautéed in butter, providing a flavorful base for our rice. If you’re using parsley or chives for garnish, chop those too and set them aside. Having all these ingredients prepared and within reach will streamline the cooking process and keep us focused on creating a dish that’s both delicious and comforting.

Cooking Instructions

Now that we’ve covered the prep, let’s dive into the heart of making this delicious Japanese butter rice. We’ll start with cooking the rice to perfection, then move on to preparing the rich, flavorful butter seasoning mix.

Cooking the Rice

  1. Begin by draining the soaked rice thoroughly to remove excess water. This step ensures that the rice cooks evenly and has just the right texture.
  2. Place the rice in a medium-sized saucepan and add 2 cups of fresh water. Turn the heat to medium and bring the water to a gentle boil.
  3. As soon as the water starts boiling, reduce the heat to low. Cover the saucepan with a tight-fitting lid to prevent steam from escaping. This method helps the rice to steam perfectly.
  4. Let the rice simmer for about 18-20 minutes. Resist the urge to peek inside; the steam trapped inside is key to cooking the rice perfectly.
  5. After 20 minutes, remove the saucepan from the heat source but keep it covered. Allow the rice to sit like this for an additional 10 minutes. The residual heat and steam will continue to cook the rice to perfection.
  6. Fluff the rice gently with a fork to separate the grains. This step ensures the rice is fluffy and every grain stands out beautifully.

Frying the Rice

  1. While the rice is resting, heat a large skillet over medium heat. Add 2 tablespoons of unsalted butter to the skillet and let it melt slowly, watching it turn foamy.
  2. Once the butter has melted, add one finely chopped onion to the skillet. Sauté the onion until it’s translucent and slightly golden, stirring frequently for about 5 minutes. The onions should exude a sweet, aromatic scent that will be the base of our seasoning.
  3. Stir in two minced garlic cloves into the skillet with onions. Continue to cook for another 1-2 minutes until the garlic is fragrant. Be careful not to let the garlic brown too much, as it can become bitter.
  4. Add the cooked rice to the skillet with the onion and garlic mixture. Gently fold in the rice to ensure it’s well coated with the buttery onion and garlic mix.
  5. Pour in 1/4 cup of your preferred broth (chicken or vegetable works great) and season with salt and pepper according to taste. The broth not only adds moisture but infuses the rice with rich, savory flavors.
  6. Cook the mixture, stirring occasionally, until all the liquid is absorbed and the rice is heated through, about 5-7 minutes.
  7. Taste and adjust the seasonings if necessary. The final dish should have a beautiful sheen, tender grains, and a buttery, comforting aroma that invites you to take a bite immediately.

Assembling the Japanese Butter Rice

After meticulously cooking the rice and preparing our rich, buttery seasoning mix, it’s time to bring all the elements together to create our mouthwatering Japanese butter rice. This final step is where the magic happens, transforming simple ingredients into a comforting and savory dish that’s perfect for any meal of the day.

Combining the Rice and Butter Mixture

First, we ensure our cooked rice is fluffed and ready to absorb the delicious flavors we’ve prepared. With a gentle hand, we fold the sautéed onion, garlic, and butter mixture into the rice, making sure each grain is evenly coated. This step is not just about mixing; it’s about marrying the flavors to ensure each bite is as sumptuous as the last.

Adding the Final Touches

To elevate our Japanese butter rice, we introduce a sprinkle of finely chopped green onions and a dash of soy sauce. The green onions offer a fresh, crisp contrast to the rich butter, while the soy sauce brings umami and depth, balancing the dish’s overall taste profile. We mix these ingredients gently, taking care not to mash the rice grains, until the rice displays a beautiful, even color and the aroma becomes irresistible.

Taste Test and Adjust

Before we declare our dish complete, we conduct a crucial taste test. This is our moment to adjust the seasoning, adding a little more soy sauce or a pinch of salt if needed. It’s essential that our Japanese butter rice hits all the right notes of savory, buttery, and subtly sweet.

Serving Suggestions

Finally, we transfer our Japanese butter rice to a serving dish, fluffing it lightly with a fork to ensure it’s airy and inviting. For a truly authentic experience, we might garnish with additional green onions or even a sprinkle of sesame seeds for extra texture. Served steaming hot, this dish is not only a feast for the taste buds but also a soothing comfort food that’s sure to satisfy.

Through these steps, we’ve assembled a dish that’s much greater than the sum of its parts. Our Japanese butter rice is ready to shine as the star of a meal or to complement a wide array of main dishes, embodying the simplicity and elegance of Japanese home cooking with a buttery twist.

Make-Ahead Tips

Navigating through a busy week can make cooking a fresh meal every night a daunting task. That’s where make-ahead tips come into play, especially for a comforting dish like Japanese butter rice. Here, we’ll explore how you can prepare parts of this dish in advance to save time and still enjoy its delightful flavors.

Rice Prep

Firstly, rice is the canvas of this dish, so getting it right is essential. You can cook the rice up to 2 days ahead. Once cooled, store it in an airtight container in the refrigerator. This step not only saves time but actually improves the texture of the rice for when it’s mixed with the butter and seasonings.

Butter Seasoning Mix

The heart of this dish lies in its flavorful buttery seasoning. You can prepare this mix in advance by combining softened butter with finely chopped green onions and soy sauce. Shape the mixture into a log using parchment paper and refrigerate or freeze it. Whenever you’re ready to prepare the dish, simply slice off the amount you need and let it melt through the warm rice for an instant flavor boost.

Green Onions

Chopping green onions might seem minor, but on a busy day, every minute counts. Chop them ahead of the time, and store them in an airtight container in the fridge. They will stay fresh for up to a week and can be sprinkled on top of your dish for a pop of color and flavor.

Portioning and Freezing

Japanese butter rice freezes beautifully. If you prefer, you can make a larger batch, portion it out, and then freeze it. To serve, thaw a portion in the refrigerator overnight or warm it directly in a pan or microwave. Add a little extra butter or a splash of water to bring back the dish’s creamy texture.

By incorporating these make-ahead tips into your meal prep routine, you’ll find that putting together a comforting bowl of Japanese butter rice becomes a quick and straightforward task. These steps not only save time but also preserve the essence of this delightful dish, ensuring you can enjoy its comforting taste any day of the week.

Storing and Reheating

After savoring the comforting flavors of Japanese butter rice, ensuring the leftovers are stored properly is crucial to enjoy this dish again. Here, we’ll guide you through the best methods for storing and reheating Japanese butter rice to preserve its freshness and taste.

Storing Japanese Butter Rice

  1. Cool Down: Begin by allowing the rice to cool to room temperature. However, avoid leaving it out for more than two hours to prevent bacterial growth.
  2. Airtight Container: Transfer the cooled rice into an airtight container. This is vital to prevent the rice from absorbing odors from the refrigerator and also keeps the rice moist.
  3. Refrigerator: Store the container in the refrigerator. The rice will stay fresh for up to 5 days.

Reheating Japanese Butter Rice

When it comes to reheating, the key is to restore the rice’s original texture and flavor as much as possible.

1. Microwave Method:

    • Add a splash of water (about 1-2 tablespoons for a single serving) to the rice. This helps to rehydrate it.
    • Cover the rice loosely with a microwave-safe lid or a damp paper towel. This helps in retaining moisture.
    • Heat on medium power in 30-second intervals, fluffing the rice with a fork in between, until it’s thoroughly warmed.

    2. Stovetop Method:

      • In a pan, add the rice along with a splash of water (about 1-2 tablespoons for a single serving).
      • Cover with a tight-fitting lid and heat over a low flame.
      • Stir occasionally until the rice is evenly heated through.
      • If you’re feeling adventurous, you can add a tiny piece of butter during reheating to enhance the flavor.

      3. Steam Reheating:

        • For those who prefer not to use a microwave or stove, steaming is an excellent alternative.
        • Place the rice in a steamer over boiling water, ensuring the rice is covered with cheesecloth or a lid.
        • Steam for a few minutes until it’s hot all the way through.


        We’ve walked through the delightful journey of making Japanese butter rice, from its simple beginnings to tips for making it ahead of time.
