Easy Onigirazu Recipe (Tuna Mayo)
Print Pin SaveIngredients
- 1 canned Tuna, See other fillings at onigirazu variations
- 1 Tbsp Mayonnaise
- A pinch Salt
- ½ Carrot
- 1 cup Lettuce
- 2 servings Cooked Rice, about 400g
- 2 Nori Sheets
Instructions
- Prepare the Fillings: Drain the canned tuna and mix it with mayonnaise and a pinch of salt in a small bowl. Shred the carrot, microwave it for 30 seconds to soften, and add a little salt. Wash the lettuce and tear it into bite-sized pieces.
- Assemble the Onigirazu: Lay a sheet of plastic wrap on a flat surface. Place a nori sheet on top, shiny side down. Spread some rice in the center, shaping it into a small square. Add the filling on top. Cover it with another layer of rice.
- Fold the Nori: Fold the corners of the nori toward the center, wrapping the fillings into a square. Use the plastic wrap to tightly wrap the onigirazu and gently press it so it holds its shape.
- Slice and Serve: Let it sit for a few minutes so the nori softens and sticks. Then, cut it in half (wet it slightly to prevent sticking) and enjoy!
