These albacore tuna sliders offer a sophisticated twist on the classic fish sandwich, featuring succulent tuna loin marinated in a savoury blend of soy sauce and spices. This high-protein dish relies on quality ingredients, using fresh heirloom tomatoes and peppery rocket to provide a crisp contrast to the rich, seared fish. By scoring the tuna before marinating, the flavours penetrate deep into the flesh, ensuring every bite is seasoned to perfection.
Ideal for a light summer dinner or a decadent weekend lunch, these sliders are best served on toasted brioche buns for a touch of sweetness. The quick grilling time keeps the tuna tender and moist, making this a fantastic option for those seeking a nutritious, heart-healthy meal that doesn't compromise on flavour. Serve them with a dollop of tangy tartar sauce for the ultimate homemade takeaway experience.

Ingredients for Albacore Tuna Sliders
450g albacore tuna loin (ask for a piece off the front end, for even thickness)
2 tablespoons soy sauce
2 tablespoons extra-virgin olive oil
2 tablespoons Northwest Seafood Seasoning
1/2 teaspoons crushed red pepper flakes
Slider buns, brioche, if possible
1 medium heirloom tomato or other ripe beefsteak tomato, thinly sliced
Rocket leaves, rinsed and dried
Tartar sauce, such as Pike Place Fish Smoked Walla Walla Onion Tartar Sauce
How to make Albacore Tuna Sliders
Back to contentsRemove the skin from the tuna and score the flesh every inch with a knife, as if you were making steaks. Repeat on all sides, but make sure not to cut all the way through.
Mix the soy sauce, olive oil, seafood seasoning, and red pepper flakes in a small bowl. Using a basting brush, brush the mixture on all sides of the tuna, making sure to get some marinade inside the scored parts of the fish, so it's well coated. Marinate at room temperature for 15 to 20 minutes.
Preheat a grill to high. Make sure the grates are clean and well oiled. Put the tuna directly on the grill and cook for about 2 to 3 minutes on each side, or 6 minutes total for rare. During the last minute of cooking, toast the buns on the grill. Slice the tuna into four sections along score lines. Serve on the buns with sliced tomato, rocket, and your favourite condiment.
