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)

Dry the fish
Pat the barramundi fillets thoroughly with paper towels until the skin is completely dry.
Time: PT2M
Season both sides
Season each fillet evenly with kosher salt and freshly ground black pepper.

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.

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.

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.
