This Tuna Rice Balls recipe comes together in about 30 minutes and is all about that hands-on fun, perfect for a quick and easy weeknight meal that your family will love!
Ingredients You’ll Need
- 2 cups cooked sushi rice: This is the star of your rice balls! Feel free to use leftover rice if you have it.
- 1 can tuna, drained: I prefer solid yet flaky tuna for added texture, but any tuna you like works!
- 3 tablespoons Kewpie mayo: If you’ve never tried this Japanese mayo, you’re in for a treat! It adds a creamy, rich flavor.
- 1 tablespoon sriracha (adjust to taste): This is where the heat comes in! Add less if you’ve got little ones, or more if you like it fiery.
- Roasted seaweed sheets (nori): Essential for wrapping or serving on the side. It adds a salty crunch that’s just heavenly!
- Salt, to taste: Just a couple pinches to enhance those flavors.
- Sesame seeds (optional, for garnish): Yes, please! They add a nice little crunch and a bit of flair.
Step-by-Step Instructions
Mix the Filling (5 minutes): Start by grabbing a bowl and combining the drained tuna with Kewpie mayo and sriracha. Add a couple pinches of salt to taste. Stir it all together until it’s well mixed. You want it creamy and slightly spicy, smell that? Yum!
Prep Your Rice (5 minutes): If you haven’t cooked your sushi rice yet, make sure that’s done before progressing. Sushi rice is stickier than regular rice, which is perfect for making those compact rice balls.
Shape the Rice (10 minutes): Now for the fun part! Wet your hands (this really helps the rice not stick) and grab about 1/2 cup of sushi rice. Flatten it in the palm of your hand to create a small bowl shape. Here’s where you’ll scoop in a spoonful of that tasty spicy tuna mixture we whipped up earlier.
Form the Balls (5 minutes): Gently fold the rice over the filling to mold it into a triangle or oval-shaped ball, your choice! This step might feel a bit tricky at first, but just keep molding until you’ve got a nice, compact shape.
Add Nori (3 minutes): You can either wrap your rice ball with a strip of nori or serve it with the nori on the side, your call! I like a little strip around my rice ball for that extra crunch, but it’s also fun to dip it in.
Finish with Sesame Seeds (optional): If you want to add some visual appeal and a hint of nuttiness, sprinkle sesame seeds on top of your rice balls. Seriously, aren’t they adorable?
Serve & Enjoy!: These can be enjoyed immediately as a snack, breakfast treat, or a quick meal. Don’t forget to share with the family, or maybe not; they might just disappear faster than you can say “spicy tuna!”
