The rice is everything here. Japanese short-grain like Koshihikari gives that signature sticky, creamy texture—Jasmine or Arborio won’t work the same. I grab mine from Asian markets or the international aisle at Whole Foods. Rinse it until the water runs completely clear (takes 4-5 washes) to remove excess starch. The mayonnaise needs to be full-fat—Kewpie if you can find it, Hellmann’s otherwise.

No rice vinegar? Apple cider vinegar at half the amount works in a pinch. Short on veggies? Pickled radish or shredded cabbage add great crunch. The eggs can be omitted for a vegan version—avocado slices give a similar creamy contrast. For extra umami, a dash of dashi powder (found at Japanese grocers) takes this to restaurant level.

Best served immediately, but holds up 2 days refrigerated (the rice hardens slightly). Store components separately to maintain texture. Nori strips lose crispness quickly, so add them fresh. This doesn’t freeze well—the mayonnaise separates.

Step-by-Step Instructions for Rice Mayonnaise

Master the technique for this comforting dish with a velvety texture and balanced flavors.

Step 1: Prepare and Cook the Rice

Rinse the 2 cups Japanese Short-Grain Rice under cold water until the water runs clear. This removes excess starch and prevents a gummy texture. Drain well and transfer to a rice cooker or heavy-bottomed pot with 2 cups of water.

Cook the rice until tender and the water is absorbed, about 20-25 minutes. Let it sit covered for an additional 10 minutes to steam. The grains should be slightly sticky but still distinct. Spread the cooked rice on a baking sheet and let it cool to room temperature—this prevents the mayonnaise from melting or separating when mixed.

Step 2: Prepare the Vegetables and Garnishes

Julienne the 1 whole Carrot into thin matchsticks for a delicate crunch. Thinly slice the 0.5 whole Cucumber after seeding it to remove excess moisture that could dilute the dish. Thinly slice the 3 whole Scallions on a bias for visual appeal.

Toast the 2 sheets Nori Sheets lightly over a flame or in a dry pan, then cut into thin strips. Toast the 1 tbsp Sesame Seeds in the same pan until fragrant and golden. Hard-boil the 2 whole Large Eggs for 9-10 minutes, then cool, peel, and slice thinly.

Step 3: Season the Rice Base

In a small bowl, whisk together the 2 tbsp Rice Vinegar, 1 tsp Granulated Sugar, and 0.5 tsp Salt until the sugar and salt dissolve completely. This creates a balanced seasoning liquid that enhances the rice without overpowering it.

Pour the mixture over the cooled rice and fold gently with a rice paddle or spatula. The rice should glisten slightly but not be soggy. Taste and adjust seasoning if needed—this is your foundation, so it should be perfectly balanced before adding the mayonnaise.

Step 4: Incorporate the Mayonnaise

Add the 0.75 cup Mayonnaise to the seasoned rice in 2-3 additions, folding gently after each to ensure even distribution. The mayonnaise should coat each grain lightly, creating a creamy texture without making the dish heavy or greasy.

Drizzle the 1 tbsp Soy Sauce over the mixture and fold once more. The soy sauce adds depth and umami, complementing the richness of the mayonnaise. The rice should now have a glossy, creamy appearance.

Step 5: Assemble and Garnish

Transfer the rice to a serving bowl or individual plates. Arrange the sliced Large Eggs, Carrot, Cucumber, and Scallions on top for a colorful presentation. Sprinkle with the toasted Nori Sheets and Sesame Seeds.

Serve immediately at room temperature. The contrast of temperatures—cool rice, room-temperature garnishes—enhances the creamy texture and comforting appeal of this dish.

Creative Variations of rice mayonnaise

Spicy Sriracha Kick

Add 1-2 tbsp Sriracha to the mayonnaise before folding into the rice for a creamy-spicy fusion. The heat cuts through the richness beautifully. I also sprinkle crushed red pepper flakes on top for extra warmth. 🌶️

Mediterranean Twist

Replace rice vinegar with lemon juice and add ½ cup diced kalamata olives and ¼ cup crumbled feta to the finished dish. The briny olives and tangy cheese create a fresh, bright variation that still feels comforting.

Vegan Delight

Swap regular mayonnaise for Kewpie vegan mayo or Just Mayo. Replace eggs with ½ avocado sliced and ¼ cup chickpeas for protein. The creaminess remains intact while keeping it plant-based.

Protein Power Bowl

Add ½ cup flaked imitation crab or chopped rotisserie chicken to make this a heartier main dish. The protein absorbs the creamy dressing beautifully. I love using Trader Joe’s crab sticks for an easy seafood flavor.

Kids’ Friendly Version

Reduce the soy sauce to ½ tbsp and add ½ cup diced ham and ¼ cup sweet corn. The familiar flavors make it more approachable for picky eaters while keeping the creamy texture they love.

Herb Garden Fresh

Mix 2 tbsp chopped fresh dill and 1 tbsp parsley into the rice mixture. The herbs add a bright, fresh note that complements the creamy base perfectly. 💛
