Ingredients (Serves 4)

4 white fish fillets (such as barramundi, snapper, cod, or hake)
Salt and freshly ground black pepper, to taste
2 tablespoons olive oil
60 g unsalted butter
2 cloves garlic, finely minced
Zest of 1 lemon
Juice of 1 lemon
1 tablespoon fresh parsley, finely chopped
1 teaspoon fresh thyme or dill (optional)
Lemon slices, for serving

Instructions

1. Prepare the Fish

Pat the fish fillets dry with paper towel. Season both sides lightly with salt and black pepper. This helps ensure even cooking and enhances the natural flavour of the fish.

2. Heat the Pan

Heat olive oil in a large frying pan over medium heat. Once hot, add the fish fillets, presentation side down. Cook for 3–4 minutes without moving, until a golden crust forms.

3. Flip and Add Butter

Carefully flip the fillets and cook for another 2–3 minutes, depending on thickness. Reduce heat to medium-low and add the butter to the pan.

4. Build the Lemon Butter Sauce

Once the butter has melted, add the garlic and cook for 30 seconds until fragrant. Stir in the lemon zest, lemon juice, and herbs. Spoon the sauce over the fish as it finishes cooking.

5. Finish and Serve

Remove from heat once the fish flakes easily with a fork. Spoon extra sauce over the fillets and garnish with fresh parsley and lemon slices.
