Bluefin Teriyaki Tuna Recipe

Off the coast of Boston, Stellwagens Bank sees the mighty Bluefin Tuna hunt their way North. From commercial crews out of Gloucester to rod-and-reel giants landed near Provincetown, Atlantic bluefin has fueled New England docks for generations. We love to combine it with our signature Teriyaki sauce to bring sweet and savory flavors out of the seared tuna meat.

Cast Iron Seared Bluefin Tuna

Ingredients

The Fish 1 lb Bluefin tuna loin (cut into 1.5-inch thick steaks)

The Sauce 1/4 cup Soy sauce, 1/4 cup Mirin, 2 tbsp Sake, 1 tbsp Brown sugar

Aromatics 1 tsp Grated fresh ginger, 1 clove Minced garlic

Finish Neutral oil (grapeseed or avocado), Toasted sesame seeds, Scallions

 

Prep the Glaze: In a small saucepan, combine the soy sauce, mirin, sake, sugar, ginger, and garlic. Simmer over medium heat for 5–8 minutes until it reduces by half and becomes syrupy. Set aside to cool slightly.

Temper the Tuna: Take the tuna out of the fridge about 15 minutes before cooking. Pat it bone-dry with paper towels. Dry fish equals a better sear.

The High-Heat Sear: Heat a heavy skillet (cast iron is best) over high heat with a tablespoon of oil until it’s shimmering and just starting to smoke.

60-Second Rule: Place the tuna in the pan. Sear for only 45–60 seconds per side. You are looking for a dark, crusty exterior and a cool, ruby-red interior.

The Glaze: In the final 20 seconds of cooking, pour half of your reduced teriyaki sauce into the pan. It will bubble and thicken instantly. Roll the tuna in the glaze to coat all sides, then remove immediately from the heat.

Rest & Slice: Let the fish rest for 2 minutes on a cutting board. Slice into 1/2-inch thick pieces using a very sharp knife.

Pro-Tips for the Perfect Plate

Don't Marinate: With high-quality bluefin, do not marinate the fish beforehand. The salt in the soy sauce will "cook" the delicate proteins and ruin the texture. Glaze at the end instead.

Sustainability Note: Bluefin is a prized catch. If you can’t find it or want a more sustainable daily option, Yellowfin (Ahi) works great, though it is leaner and will need a tiny bit more oil.

The "Sizzle" Check: If the pan isn't screaming hot when the fish hits it, you'll end up with a grey, overcooked ring around the center before you get a good crust.

Finishing Tip: Serve this over a bed of jasmine rice or stir-fried bok choy to soak up the extra glaze.

The Sake Pairing: Junmai Ginjo

For a fatty fish like bluefin paired with a sweet glaze, you want a Junmai Ginjo sake.

Why it works: Junmai Ginjo is typically brewed at lower temperatures, resulting in a floral, fruity profile with a clean, slightly acidic finish. This acidity acts as a "palate cleanser," cutting through the tuna's fat and the sugar in the teriyaki sauce.

Serving Temp: Chilled (around 10°C / 50°F).

Specific Profile: Look for one described as "Dry" (Karaguchi). A bone-dry sake provides a sharp contrast to the caramelized glaze on the fish.
