Ingredients

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.
  4. Step 4: While tuna cooks, dice 1/2 cup cucumber and 1/4 avocado. Squeeze juice from 1/2 lime over the mixture, then gently toss until combined. Serve the tuna immediately with the cucumber salad on the side.

How do I store leftover Coconut-Crusted Tuna with Cucumber Salad?

Cool to room temperature within 2 hours, then store in an airtight container in the fridge for up to 4 days. Reheat covered in a 350°F oven for 10-12 minutes, or microwave at 70% power in 60-second bursts to keep tuna steak from drying out.

Can I substitute ingredients in Coconut-Crusted Tuna with Cucumber Salad?

For aromatics, dried herbs at ⅓ the volume of fresh work in a pinch. The full ingredient list is shoppable on Instacart so you can see substitutes in real time.

How do I scale Coconut-Crusted Tuna with Cucumber Salad for a different number of people?

The recipe is written for 1 servings. Multiply each ingredient by (your serving target / 1). Cook time stays roughly the same up to 2x; for 3-4x batches, switch from a skillet to a sheet pan or stockpot so the food isn't crowded — overcrowding steams instead of browns.
