Frequently Asked Questions About Bluefin Tuna
What is the difference between bluefin tuna and regular tuna?
Bluefin tuna is one species within the broader tuna group, not a synonym for every tuna. Canned tuna often comes from other species, while bluefin is especially prized for its rich, red flesh and fatty belly cuts.
Can you eat bluefin tuna raw?
Yes, bluefin tuna is commonly served raw as sushi or sashimi when it has been handled for raw consumption. Buy it from a reputable fishmonger, keep it properly chilled, and follow safe handling instructions at home.
How do you cook a bluefin tuna steak?
Cook a bluefin tuna steak quickly over high heat in a hot pan or on a grill. Searing the outside while leaving the center less cooked helps preserve its moist, meaty texture; prolonged cooking can make it dry.
Why is bluefin tuna so expensive?
Bluefin tuna can command a high price because it is in demand for sushi and sashimi, and its prized belly cuts are rich and fatty. Price also varies with the fish’s quality, size, supply, and where it is sold.
What does bluefin tuna taste like?
Bluefin tuna has a rich, savory flavor and a firm, meaty texture. Its belly is typically fattier and more tender than the leaner back, which is why different cuts can taste and feel quite distinct.
Is bluefin tuna high in mercury?
Yes, mercury can build up in bluefin tuna because it is a large predatory fish. Limit how often you eat it, particularly during pregnancy; ask a doctor or dietitian for advice suited to your circumstances.
How can you tell if bluefin tuna is fresh?
Fresh bluefin tuna should smell clean and mild, not sour or strongly fishy, and its flesh should look moist and firm. If you plan to eat it raw, ask the seller whether it was handled for raw consumption.
How long does bluefin tuna last in the fridge?
Keep raw bluefin tuna cold in a sealed container and use it as soon as possible. Store it away from other foods to prevent drips or contact, and discard it if it has been left at room temperature for too long.
Can you freeze bluefin tuna?
Yes, bluefin tuna can be frozen in airtight packaging. Thaw it in the refrigerator and use it promptly; freezing can affect texture and does not make fish that was already mishandled safe to eat.
Is bluefin tuna different from yellowfin tuna?
Yes, bluefin and yellowfin are different tuna species. Bluefin is often richer and fattier, especially in the belly, while yellowfin is generally leaner; flavor and texture also depend on the cut and preparation.

What is Bluefin Tuna?
Bluefin tuna is a large, migratory ocean fish with firm, dark-red flesh and a rich, meaty flavour. It is prized in Japanese cooking, where carefully handled cuts are served as sashimi or sushi; elsewhere, fresh steaks are often seared or grilled, while canned tuna is a more familiar everyday option in many kitchens.
Its substantial texture stands up well to a quick sear, but prolonged cooking can make it dry. Bluefin tuna is notably high in protein, with 28.8 g per 100 g. Pair a cooked steak with lemon, crisp salad or vegetables, and use a light hand with added oil to let the fish’s flavour come through.
