Ahi Tuna Sushi Rolls with Avocado: Classic or Spicy

October 18, 2024

Ahi Tuna Sushi Rolls with Avocado and Cucumber

These nori-outside rolls combine tuna strips, seasoned rice, avocado and cucumber. Choose the classic filling or the spicy variation below. The vegetable-filled version is a home-style maki roll rather than a tuna-only tekka maki.

Makes: 4 rolls, cut into 6–8 pieces each (24–32 pieces). Serves about 2 as a meal or 4 with other dishes. Allow about 45–60 minutes, depending on rice cooking and rolling practice.

Choose the Tuna and Preparation

For the raw version, confirm the specific fish's intended use and handling with the supplier. A “sushi-grade” name or frozen condition alone does not guarantee safety. Yellowfin Saku Blocks offer a rectangular shape for slicing; the 5 lb and 10 lb options are total order weights, not the quantity required for this recipe.

Freezing does not kill all harmful germs. Pregnant people, children, older adults and people with weakened immune systems should avoid raw or undercooked seafood. Thorough cooking is the safer option; see FDA seafood guidance.

Ingredients

Seasoned Rice

1 cup uncooked short-grain sushi rice, yielding about 3 cups cooked
Water according to the rice package or cooker instructions
2 tablespoons unseasoned rice vinegar
1 tablespoon sugar
½ teaspoon salt

Four Rolls

8 oz tuna suitable for the chosen preparation
4 full nori sheets
½ large avocado, cut into thin strips
½ small cucumber, seeded and cut into thin strips
Soy sauce, pickled ginger and optional wasabi for serving
Optional sesame seeds

Have a clean bamboo rolling mat, sharp knife, rice paddle and small bowl of water ready. Check sauce labels for fish, soy, wheat, sesame and other allergens.

Prepare the Rice and Filling

Rinse and cook the rice according to its package. Dissolve the sugar and salt in the vinegar, warming gently if needed.
Transfer cooked rice to a wide bowl and gently fold in the vinegar mixture without crushing the grains. Let it cool enough to handle and no longer be hot before adding raw fish. Prepare it for this meal rather than leaving it out for an extended period.
Prepare vegetables on a clean board. Keep tuna refrigerated until needed; follow its thawing directions, including instructions about opening or removing wrapping.
For the raw version, cut tuna across the grain into long, roughly ¼-inch-thick strips using smooth drawing cuts. Keep unused fish chilled while rolling.

Roll, Cut and Serve

Place one nori sheet shiny-side down on the mat. Lightly dampen your hands and spread about ¾ cup cooked, seasoned rice in a thin layer, leaving roughly 1 inch clear along the far edge.
Arrange one-quarter of the tuna, avocado and cucumber across the lower third. Reduce filling if the roll is difficult to close.
Lift the near edge with the mat and roll over the filling. Apply gentle, even pressure, keeping the mat outside the roll. Lightly moisten the bare nori edge to seal.
Set seam-side down. Repeat with the remaining ingredients. If using food wrap on the mat, remove every piece of wrap before cutting and serving.
Use a sharp, lightly dampened knife to halve each roll, then cut each half into 3–4 pieces. Wipe the blade between cuts. Serve promptly with the accompaniments.

Spicy Tuna Variation

For all four rolls, finely chop the 8 oz tuna and mix with 1 tablespoon mayonnaise and 1 teaspoon Sriracha, adding more Sriracha to taste. Use this filling instead of the tuna strips. Add sauce gradually so the filling holds together; keep it refrigerated until assembly.

Cooked Tuna Option

Cook fresh or thawed tuna to 145°F internally, then flake it for the filling. Use about 8 oz cooked fish across the four rolls; that requires more than 8 oz raw fish because cooking changes the weight. Cool promptly under refrigeration if preparing ahead. A quick surface sear with a raw center is still an undercooked preparation.

For a canned option, use 8 oz drained canned tuna. Drain thoroughly and add a little mayonnaise if needed to bind the flakes. Canned tuna is a different product from the uncooked fish sold in the linked listings.

Rolling Tips and Meal Planning

If a roll splits, reduce the filling. If rice sticks to your fingers, dampen them lightly rather than soaking the nori. A clean blade and gentle cuts help prevent crushed pieces. Serve with cooked edamame, miso soup or a cucumber salad.

Make only what you plan to serve and refrigerate perishable ingredients promptly. Do not treat a blanket 24-hour storage claim as a guarantee for homemade raw-fish rolls.
