It has a dark blue back and upper sides with a silver belly and smaller yellow fins. Yellowfin tuna has yellow fins that are located at the top of its body and are longer, while yellowtail tuna has yellow fins that are located at the bottom of its body and are smaller.

Yellowfin tuna is considered to have a stronger flavor and firmer texture than yellowtail tuna. Yellowfin tuna is often used for sashimi and sushi, while yellowtail tuna is often grilled or served as sashimi. Yellowtail tuna is considered to be a good choice for grilling or cooking because of its milder flavor and softer texture. It is also considered to be a good choice for raw fish dishes because of its softer texture and milder flavor.

Bluefin tuna grows larger than yellowfin and ofcourse does not have the distinctive yellow fins. Some Bluefin tuna reach over 1,000 pounds, while yellowfin usually max out around 400 pounds.

Yellowfin tuna (Ahi) is known for its mild flavor and firm texture, making it perfect for grilling and searing, while bluefin tuna has a richer, more buttery taste, ideal for high-end sushi and sashimi.When it comes to color, yellowfin tuna has a bright red flesh that lightens when cooked, while bluefin tuna’s flesh is a deeper red and prized for its melt in your mouth texture when served raw.

While both species are prized in culinary circles, yellowfin is often favored for its sustainability, as bluefin tuna populations have been overfished and are more critically endangered.

How to Cook Yellowfin Tuna Ahi

See below for some recommendations on how to cook Yellowfin or Ahi Tuna.

Seared Ahi Tuna

To achieve the perfect crust on seared ahi tuna, pat the tuna steaks dry and season them generously with salt, pepper, and sesame seeds before searing. Preheat your pan to high heat with a bit of oil, and sear the tuna for about 1-2 minutes on each side…just enough to form a golden brown crust while keeping the center rare. Make sure your tuna is sushi grade if you plan to serve it rare or medium rare, and let it rest for a minute before slicing for that perfect presentation.

Grilled Yellowfin Ahi Tuna with a Citrus Marinade

For a flavorful grilled yellowfin tuna, marinate the fish in a citrus blend of lemon, lime, garlic, and olive oil for at least 30 minutes to let the flavors soak in. Grill the tuna over medium to high heat for 2-3 minutes per side, ensuring you don’t overcook it. The goal is a tender, flaky inside with a slightly charred exterior. Serve the grilled yellowfin tuna with a fresh squeeze of citrus on top to really bring out the bright, zesty flavors of the marinade.

Ahi Poke Bowls

Start by sourcing the freshest sushi grade ahi tuna you can find, and dice it into small, even cubes for the perfect poke texture. Mix the tuna with soy sauce, sesame oil, green onions, and a bit of sriracha or chili flakes for a spicy kick, letting it marinate for at least 15 minutes. Assemble your poke bowl by layering rice, avocado, cucumber, and seaweed salad, then top it off with your marinated ahi and a sprinkle of sesame seeds.

Yellowfin Ahi Sushi and Sashimi Preparations

For sushi, slice your ahi tuna into thin, even pieces to lay atop seasoned sushi rice, making sure the fish is fresh and chilled before serving.

When preparing sashimi, use a sharp knife to cut the tuna into thicker, clean slices, and serve it simply with soy sauce, wasabi, and pickled ginger. Ensure your tuna is sushi grade and free from any veins or imperfections, as sushi and sashimi rely on the highest quality, freshest fish for the best flavor.
