Ingredients
- 2 fillets (6 oz each) barramundi fillets
- 4 tbsp unsalted butter
- 2 tbsp shallots, finely chopped
- 1/3 cup dry white wine
- 2 tbsp heavy cream
- 2 tbsp finger lime pearls
- 1/2 tsp sea salt
- 1/4 tsp freshly ground white pepper
- 1 tbsp olive oil
- 1 tsp lemon zest
Instructions
- Step 1: Preheat oven to 275°F (135°C). Lightly brush 2 barramundi fillets with 1 tbsp olive oil and season both sides with 1/2 tsp sea salt and 1/4 tsp freshly ground white pepper.
- Step 2: Place the fillets in a shallow baking dish and slow cook in the oven for 20-25 minutes until the fish is opaque and flakes easily with a fork.
- Step 3: While the fish cooks, prepare the beurre blanc: melt 2 tbsp unsalted butter in a small saucepan over medium heat and sauté 2 tbsp finely chopped shallots until translucent and fragrant, about 2 minutes.
- Step 4: Add 1/3 cup dry white wine and simmer until reduced by half, then whisk in 2 tbsp heavy cream and the remaining 2 tbsp unsalted butter, whisking constantly until the sauce thickens and coats the back of a spoon.
- Step 5: Remove from heat and gently fold in 2 tbsp finger lime pearls and 1 tsp lemon zest, allowing the citrus pearls to burst and add texture.
- Step 6: Plate the slow-cooked barramundi fillets and spoon the finger lime beurre blanc generously over the top before serving.
