Ingredients

Instructions

  1. Step 1: In a shallow bowl, mix 3/4 cup chopped macadamia nuts and 1/2 cup panko breadcrumbs with 1 tsp sea salt and 1/2 tsp black pepper for a crunchy crust.
  2. Step 2: Pat dry 4 barramundi fillets (6 oz each), then press each fillet firmly into the macadamia-panko mixture to coat the top side evenly.
  3. Step 3: Heat 2 tbsp olive oil in a large nonstick skillet over medium heat. Add the fillets crust-side down and cook for 4-5 minutes until the crust is golden brown and crispy.
  4. Step 4: Carefully flip the fillets and cook the other side for 3-4 minutes until the fish flakes easily with a fork.
  5. Step 5: Meanwhile, melt 4 tbsp unsalted butter in a small saucepan over low heat. Stir in 1 tsp lemon zest and 2 tbsp fresh lemon juice, gently warming until combined.
  6. Step 6: Plate the barramundi fillets and drizzle the lemon butter sauce over the top for a bright finish.

How do I store leftover Barramundi with Macadamia-Crust and Lemon Butter Sauce?

Transfer to an airtight jar and refrigerate for up to 5–7 days. Most sauces freeze well for up to 2 months — portion into small containers or freezer bags so you can thaw only what you need. Stir before serving; cream- or yogurt-based sauces may separate on standing.

Can I substitute ingredients in Barramundi with Macadamia-Crust and Lemon Butter Sauce?

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 Barramundi with Macadamia-Crust and Lemon Butter Sauce for a different number of people?

The recipe is written for 4 servings. Multiply each ingredient by (your serving target / 4). 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.
