Ingredients You’ll Need

This Spicy Watermelon Vegan Sushi comes together with just a handful of simple but purposeful ingredients. Each one brings something unique—whether it’s vibrant color, umami flavor, or a creamy kick—to deliver that crave-worthy balance of taste and texture.

• Vegan Mayonnaise: This forms the luscious, spicy base for the watermelon filling; opt for your favorite store-bought brand or make your own.
• Sriracha: Adds the unmistakable heat and depth, giving the filling its “spicy” character without overpowering the sweetness.
• Soy Sauce: Brings a touch of salty umami to round out flavors and balance the melon.
• White Miso Paste: Infuses an extra punch of savory, fermented complexity to the sauce—a secret weapon for plant-based recipes.
• Sesame Oil: A drizzle creates an irresistibly nutty, aromatic finish that pairs perfectly with both sushi rice and watermelon.
• Watermelon (finely chopped): The star of the show, lending natural juiciness, vibrant color, and playful pops of sweetness.
• Nori Sheets: These seaweed wraps give structure, flavor, and classic sushi vibes to the finished rolls.
• Prepared Sushi Rice: Sticky, slightly vinegared rice is the foundation—essential for shaping and holding everything together.
• Sesame Seeds: For garnish and a little pop of crunch and toasty flavor—choose black, white, or a mix for visual flair.

Variations

One of the joys of Spicy Watermelon Vegan Sushi is how open it is to fun little tweaks—you can tailor it for whatever’s in your fridge, your taste preferences, or your next sushi-night theme! Don’t be afraid to play around; the basic foundation is always delicious.

• Avocado Upgrade: Add thin slices of avocado inside the roll for extra creaminess and that classic sushi touch.
• Crunch Factor: Slip in julienned cucumber, carrot, or daikon for a refreshing crunch alongside the spicy watermelon.
• Spice Level Control: Bump up the Sriracha for more heat, or mellow it with extra vegan mayo for a milder taste.
• Gluten-Free Option: Swap in tamari for soy sauce if you need the filling to be 100% gluten-free.

How to Make Spicy Watermelon Vegan Sushi

Step 1: Whisk Up the Spicy Sauce

In a medium mixing bowl, whisk together the vegan mayonnaise, Sriracha, soy sauce, white miso paste, and sesame oil until everything is completely blended and smooth. This sauce is where all that flavor lives, so take a second to taste and adjust the seasonings if you crave more heat or umami!

Step 2: Toss Watermelon at the Last Minute

Right before you’re ready to assemble your sushi, add the finely chopped watermelon to the spicy sauce and toss gently to coat. Don’t let the watermelon sit for too long in the sauce, or it will release its juice and make things messy—the last-minute toss keeps everything fresh and vibrant.

Step 3: Prepare the Sushi Rice & Nori

Place a sheet of nori on a bamboo sushi mat (or just a flat surface). With wet hands (this helps prevent sticking!), evenly spread a thin layer of prepared sushi rice over the nori, leaving about 2 inches bare at the top edge to help seal the roll later.

Step 4: Fill and Roll

Spoon a generous line of the spicy watermelon filling along the bottom edge of the rice, then sprinkle with sesame seeds—and any optional extras you like. Begin rolling the sushi tightly from the bottom, using gentle but firm pressure. When you reach the exposed edge, wet it with a little water to “glue” the nori closed. Finish rolling and give the cylinder a gentle squeeze to set the shape.

Step 5: Slice and Serve

Using a sharp, dampened knife, cut the roll into bite-sized rounds. If any watermelon tries to escape, just nudge it back in. Arrange on a platter, sprinkle with extra sesame seeds, and serve immediately for the freshest experience!

How to Serve Spicy Watermelon Vegan Sushi

Garnishes

A generous sprinkle of black and white sesame seeds always adds visual flair and a subtle toasty crunch. For extra pop, scatter sliced green onions, thin matchsticks of cucumber, or even a few microgreens on top. A little drizzle of extra Sriracha or a dollop of vegan mayo can be dotted over the rolls for a restaurant-style finish.

Side Dishes

Pair your Spicy Watermelon Vegan Sushi with a simple miso soup, pickled ginger, or a crisp seaweed salad for the ultimate sushi-night spread. Edamame dressed in sea salt or Japanese-style pickled vegetables are always a hit and add layers of texture and flavor.

Creative Ways to Present

For a playful twist, try serving the sushi Buddha bowl style: pile vibrant sushi rice in a bowl, add nori snacks, avocado slices, and cucumber, then top with a heap of spicy watermelon and favorite garnishes. You can also arrange sushi rounds on a dramatic platter with edible flowers and extra dipping sauces for a show-stopping appetizer display.

Make Ahead and Storage

Storing Leftovers

If you happen to have leftover Spicy Watermelon Vegan Sushi, store the rolls in an airtight container in the refrigerator for up to 24 hours. For the best texture, keep the watermelon filling and rice/nori separate until just before eating, if possible, to prevent sogginess.

Freezing

Sushi made with fresh watermelon doesn’t freeze well—the melon gets watery and the texture changes after thawing. I recommend enjoying these rolls fresh and skipping the freezer for this particular sushi adventure.

Reheating

No reheating needed! Sushi rolls are meant to be savored chilled or at room temperature. If your rolls have been in the fridge, simply let them sit out for 10–15 minutes so the flavors and texture are at their best before serving.
