Sushi Grade Tuna: What It Is and How to Prepare It.

Updated: Jun 13

What is Sushi Grade Tuna?


Sushi grade tuna, also known as sashimi grade, refers to the highest quality tuna that is safe to be eaten raw. This designation means that the fish has been frozen at a very low temperature to kill any potential parasites. The term is not regulated by the FDA, but reputable fishmongers and sushi chefs follow stringent guidelines to ensure safety and quality.


There are several types of tuna commonly used for sushi:

  • Bluefin Tuna (Maguro): Known for its rich flavor and high-fat content, especially in the fatty belly section called otoro.

  • Yellowfin Tuna (Ahi): Slightly leaner than bluefin but still highly prized for sushi.

  • Bigeye Tuna: Similar to yellowfin, with a higher fat content.

  • Albacore (Shiro Maguro): Known for its mild flavor and softer texture.


Selecting Sushi Grade Tuna


When buying sushi grade tuna, look for:

  • Color: Vibrant red for lean cuts, and a pale pink for fatty cuts.

  • Smell: Fresh and ocean-like, not fishy.

  • Texture: Firm and smooth, without any mushiness.


Always buy from a trusted fishmonger or supplier who follows proper handling and freezing protocols.

Preparing Sushi Grade Tuna


  • Thawing: If your tuna is frozen, thaw it properly. Place it in the refrigerator for 8-12 hours or submerge it in a sealed plastic bag in cold water for about an hour. Avoid thawing at room temperature to prevent bacterial growth.

  • Cutting: Use a sharp knife to make clean cuts. For sashimi, cut against the grain to ensure tenderness. For sushi, cut slices about 1/4 inch thick. Clean your knife between cuts to maintain cleanliness and precision.

  • Sashimi: To serve sashimi, place the slices on a chilled plate. Garnish with shredded daikon, shiso leaves, and serve with soy sauce, wasabi, and pickled ginger.

  • Nigiri Sushi: For nigiri, shape small mounds of sushi rice with lightly moistened hands. Place a slice of tuna over each rice mound, gently pressing it into place. You can add a dab of wasabi between the fish and the rice if desired.

  • Poke: For a modern twist, dice the tuna and mix it with soy sauce, sesame oil, green onions, and sesame seeds. Serve over rice with avocado, cucumber, and other toppings for a delicious poke bowl.


LIV VERO Magazine Tips for Enjoying Sushi Grade Tuna

  • Freshness is Key: Consume sushi grade tuna as soon as possible for the best flavor and texture.

  • Pairing: Serve with high-quality soy sauce and fresh wasabi. The condiments enhance the natural flavors without overpowering the tuna.

  • Presentation: Sushi is as much about aesthetics as it is about taste. Arrange your tuna slices artfully and garnish with fresh ingredients to elevate the dining experience.


Safety Precautions

  • Freezing: Ensure the tuna has been properly frozen to kill any parasites.

  • Hygiene: Maintain a clean workspace, use sanitized tools, and handle the fish with care to prevent contamination.

  • Storage: Store any unused tuna in the refrigerator and consume within 24 hours. Do not refreeze thawed fish.


By following these guidelines, you can enjoy the delicate and exquisite taste of sushi grade tuna safely and deliciously.
