Tropical Coconut Crusted Tuna Steak

This Tropical Coconut Crusted Tuna Steak was inspired by coconut shrimp I’d recently had while out to dinner. It’s paired with a dipping sauce of orange juice and hoisin, which is the perfect compliment to the mild sweetness of the crunchy toasted coconut crust.

Coconut Crusted Tuna Steak

I adore coconut anything and have wanted to make some sort of coconut crusted seafood for awhile now. I thought about making coconut shrimp, but after taking inventory of what seafood I already hand in the freezer, I decided that Coconut Crusted Tuna Steak had a nice ring to it.

Coconut Crusted Tuna Steak

I’m not really a tuna-fish-in-the-can girl, but I do enjoy a big fat tuna steak from time to time. I purchase them occasionally when I shop at Costco, and then I divide a large steak into three or four portions depending on how many people I’m serving.

What I like about tuna steaks is how meaty they are and that a little bit goes a long way. And, just like the name implies, they have a steak-like texture. They hold up very well to pan sauteing and also to bold flavors.

I’ve used a few Asian flavors in the marinade of these tuna steaks along with the dipping sauce. Since the winter months are all about citrus flavors and fresh oranges, I’ve combined fresh orange juice and zest along with ponzu sauce (a citrus based sauce) and ginger. The flavors of the tuna, coconut and citrus compliment each other very nicely.

The doneness of tuna steaks tends to be a personal matter. From my own point of view, I like mine cooked through the center, but some people enjoy theirs seared on the outside and nice and pink in the middle. Since cooking a tuna steak is such a personal matter, you’ll notice that the cooking time that I’ve written for this recipe is wide-ranged. Please feel free to adjust the cooking time to fit your personal preference for doneness.

You’ll also notice that the preparation time for these Coconut Crusted Tuna Steaks may seem a bit on the long side, although the actual hands on time is not very long at all. I recommend marinating the tuna steaks for approximately 20 minutes before coating with the coconut. After the steaks have been coated, I then recommend that they chill for at least 30 minutes which will keep the coconut coating from falling off the steaks during cooking.

Serves: 3-4     Prep Time: 60 minutes (includes marinate and chill time)  
Cook Time: 10 – 20 minutes

For the tuna steaks:
3 tuna steaks (approximately 4-5 ounces each)
3 tablespoons prepared ponzu sauce
2 tablespoons orange juice
salt and pepper to taste
1 cup unsweetened flaked coconut
1 cup whole wheat panko crumbs
1 tablespoon orange zest
1 teaspoon ground ginger
½ teaspoon salt
¼ teaspoon pepper
4 tablespoons coconut oil or canola oil

For the sauce:
3 tablespoons hoisin sauce
1 tablespoon ponzu sauce
1 tablespoon orange zest

-In a shallow dish or pan, pour 3 tablespoons ponzu and 2 tablespoons orange juice over the tuna steaks. Season the steaks to taste with salt and pepper. Flip to coat both sides of the fish with the sauce. Set aside and allow the steaks to marinate for at least 20 minutes.

-In another shallow dish or bowl, combine the coconut flakes, panko, orange zest, ginger, ½ teaspoon salt and ¼ teaspoon pepper. Mix well to combine.

-Press the marinated tuna steaks firmly into the coconut coating to coat all sides. Place the coated steaks on a plate or baking sheet and refrigerate the coated steaks for 30 minutes.

-Meanwhile mix the sauce ingredients in a small bowl and chill.

-In a large saute pan, heat the oil over medium heat. Add the coated tuna steaks and cook on both sides until your preferred doneness (approximately 5 minutes per side, for medium doneness).

-Serve hot along with the sauce for dipping.
