Instructions

1. Step 1: Pat 6 oz tuna steak dry with paper towels. In a shallow bowl, mix 2 tbsp unsweetened shredded coconut with 1/8 tsp sea salt and 1/8 tsp black pepper.
2. Step 2: Press both sides of the tuna steak firmly into the coconut mixture until evenly coated, then set aside for 5 minutes to set.
3. Step 3: Heat 1 tsp olive oil in a cast-iron skillet over medium-high heat until shimmering. Add the coconut-crusted tuna and cook for 3-4 minutes per side until the exterior is golden and the center is medium-rare.
