How to Cut Tuna for Tartare
Use a very sharp knife to cut the tuna into small, even ¼-inch cubes. For cleaner cuts, keep the tuna very cold and slice against the grain without pressing too hard. If the tuna is soft, place it in the freezer for 10-15 minutes before cutting so it firms up slightly.

Is It Safe to Eat Raw Tuna?
Tuna tartare should be made with tuna that is sold as safe for raw preparation. Buy it from a reputable fish market or seafood counter, keep it cold, and prepare it the same day if possible. If you are unsure whether the tuna can be eaten raw, ask your fishmonger directly before making this recipe.
The term 'sushi-grade' isn't regulated and is just a marketing term.
Avoid using regular grocery-store tuna steaks unless they are specifically labeled or confirmed safe for raw dishes. Raw seafood may not be appropriate for everyone, including pregnant people, young children, older adults, or anyone with a weakened immune system.
Tuna Tartare vs Poke
Tuna tartare is usually finely diced, lightly dressed, and served as an appetizer. Poke is often cut into larger cubes and served as a bowl with rice, vegetables, toppings, and a more generous sauce. Both use raw tuna, but tartare is typically more delicate and appetizer-focused.
Expert Tips and Tricks
Here are some expert tips to make this fresh fish dish:
- Keep everything cold: It is a good idea to chill your tuna and any bowls you'll be using before preparing. This will help maintain the tuna's freshness and texture.
- Taste as you go: Before serving, I like to taste the mixture and adjust the seasoning if needed. You might want a little more lime juice or soy sauce depending on your preference.
- Use very sharp knives: A sharp knife helps create clean cuts and prevents the tuna from tearing.
- Dice the tuna evenly: Small, uniform cubes create the best texture.
