Marinated Ahi Tuna Tacos with Asian Slaw


These Marinated Ahi Tuna Tacos put me right into another overstuffed taco situation. It was inevitable with tender, citrusy tuna nestled on crunchy Asian Slaw and drizzled with Cilantro Pistachio Pesto. My kids never tire of watching me overstuff or overfill things to the point of no return. I’d be much better off with a knife and fork, but what fun would that be? Having seam-splitting tortillas and pesto running down my arm is by far the preferred m.o. ๐Ÿ™‚

Marinated Ahi Tuna Tacos

Bathing the tuna in an Asian-inspired marinade gives it a deliciously subtle sweet and tangy flavor. Sweet Cara Cara orange combines with lemon, shallots, garlic, grated ginger, fresh parsley, soy sauce, and sesame and olive oil. Whisk together in a baking dish large enough for the tuna, and let it get happy for about 30 minutes.

Ahi Tuna Taco Marinade Ingredients

Wild Ahi Tuna Steaks

Ahi Tuna Marinating

These 1 ยฝ-inch thick wild ahi tuna steaks need no more than 1 ยฝ – 2 minutes per side on the grill over medium-high heat for a nice sear that’s still rare in the center. Cook 3-4 minutes on each side if you prefer the steaks medium and more pink inside.

Marinated Ahi Tuna Grilling

When the tuna comes off the grill let it rest 5 minutes or so before slicing. Meanwhile, grill the tortillas individually, or wrap them in foil and place on the grill to get warm. They get more of that smoky flavor when placed directly on the grates.
