Ingredients

  • 12 oz Barramundi fillets, skin‑on (Two 6‑oz pieces; pat dry with paper towels)
  • 1 tbsp Olive oil (For searing; use a high‑smoke‑point oil if preferred)
  • 1 tsp Kosher salt (Season both sides of the fish)
  • ½ tsp Freshly ground black pepper (Season both sides of the fish)
  • 2 tbsp Unsalted butter (For the pan sauce; cut into pieces)
  • 2 sprigs Fresh thyme sprigs (Adds aromatic flavor to the sauce)
  • 1 tbsp Capers, drained and rinsed (Provides briny contrast)
  • 1 tbsp Fresh lemon juice (About half a lemon; add at the end of sauce)

Instructions

  1. Dry the fish

    Pat the barramundi fillets thoroughly with paper towels until the skin is completely dry.

    Time: PT2M

  2. Season both sides

    Season each fillet evenly with kosher salt and freshly ground black pepper.

    Time: PT1M

  3. Heat the skillet

    Place the cast‑iron skillet over high heat and let it get very hot (about 2‑3 minutes).

    Time: PT2M

    Temperature: high heat

  4. Add oil and sear skin‑side

    Add 1 tbsp olive oil, swirl to coat, then lay the fillets skin‑side down. Press gently with the fish spatula for 5‑10 seconds.

    Time: PT3M

    Temperature: high heat

  5. Flip and finish cooking

    When the skin is golden and releases easily, flip the fillets and cook flesh‑side for another 2‑3 minutes, or until the fish is opaque through the middle.

    Time: PT3M

    Temperature: high heat

  6. Rest and drain

    Transfer the fish to a plate, letting excess oil drain off. Keep warm while you make the sauce.

    Time: PT1M

  7. Make the butter‑thyme‑caper sauce

    Reduce heat to medium. Add 2 tbsp butter to the same skillet; let it melt and turn lightly brown. Add thyme sprigs, letting them sizzle, then stir in capers and 1 tbsp fresh lemon juice. Swirl the pan to combine.

    Time: PT3M

    Temperature: medium heat

  8. Plate and serve

    Spoon the sauce over the rested barramundi fillets. Garnish with an extra thyme sprig if desired and serve immediately.

Critical Steps — Do Not Skip

  • Pat the fish completely dry before seasoning.
  • Ensure the skillet is hot before adding oil and fish.
  • Do not flip the fish until the skin releases easily.

Chef Tips from the Video

  • Press the fillet gently with the spatula right after it hits the pan; this helps the skin make full contact.
  • If you prefer extra crispiness, finish the skin side under a broiler for 1‑2 minutes after searing.

Troubleshooting

Fish sticks to the pan.

Make sure the skin is completely dry and the pan is hot; give the skin extra time to crisp before attempting to flip.

Sauce is too thin.

Increase butter slightly or let the sauce reduce a minute longer over medium heat.

Fish is undercooked in the center.

Cover the skillet loosely with foil for the last minute of cooking, or lower heat and cook a bit longer.

Storage

Refrigerator: Store leftovers in an airtight container for up to 2 days.

Freezer: Can freeze cooked fish (without sauce) for up to 1 month; reheat gently.

Room temperature: Do not leave at room temperature for more than 2 hours.

Make-Ahead Tips

  • Rinse and drain capers ahead of time.
  • Measure butter, thyme, and lemon juice into a small bowl for quick addition.
