Ingredients

Instructions

  1. Step 1: Season 4 barramundi fillets evenly with 1 tsp salt and 1/2 tsp black pepper on both sides.
  2. Step 2: Heat 2 tbsp olive oil in a large nonstick skillet over medium-high heat. Add the fillets skin-side down and cook for 4-5 minutes until skin is golden and crisp. Flip carefully and cook for another 2-3 minutes until fish is opaque and flakes easily.
  3. Step 3: Meanwhile, prepare the pesto by combining 1 cup fresh basil leaves, 1/2 cup toasted macadamia nuts, 1/4 cup grated parmesan cheese, 1 minced garlic clove, and 2 tbsp lemon juice in a food processor. Pulse while slowly drizzling in 1/4 cup olive oil until a coarse pesto forms.
  4. Step 4: Spoon the macadamia nut pesto generously over the cooked barramundi fillets and serve immediately with lemon wedges if desired.
