Recipe Information
Ingredients
- 2 pieces Ahi tuna steaks
- 4 tablespoons Coconut aminos
- 2 tablespoons Olive oil
- 2 tablespoons Fresh lime juice
- 1 teaspoon Garlic powder
- 1 teaspoon Onion powder
- 0.5 teaspoon Ground black pepper
- 0.5 teaspoon Sea salt
- 2 tablespoons Avocado oil
Instructions
Begin by preparing the marinade. In a small bowl, combine the coconut aminos, olive oil, fresh lime juice, garlic powder, onion powder, sea salt, and ground black pepper. Whisk the ingredients together until well blended.
Place the ahi tuna steaks in a resealable plastic bag or a shallow dish. Pour the marinade over the tuna steaks, ensuring they are evenly coated. Seal the bag or cover the dish, and let the tuna marinate in the refrigerator for at least 15 minutes, or up to 1 hour for more flavor.
Once marinated, remove the tuna steaks from the marinade and pat them dry with paper towels. This will help achieve a better sear.
Heat a large non-stick skillet or heavy pan over medium-high heat. Add the avocado oil and let it heat until it begins to shimmer.
Carefully place the tuna steaks in the pan. Sear each side for about 2-3 minutes for rare, 4 minutes for medium, or until your desired level of doneness is reached. The outside should have a nice golden crust, while the inside remains tender.
Remove the tuna steaks from the skillet and let them rest for a couple of minutes before slicing. This helps keep them juicy.
Slice the tuna steaks against the grain into half-inch thick slices.
Serve immediately, garnished with lime wedges for squeezing over the top, if desired.
