- Pat the wolffish fillets dry with paper towel and season generously on both sides with sea salt and black pepper.
- Heat olive oil in a heavy skillet over medium-high heat until shimmering, then place the fillets skin-side down and sear undisturbed for 4–5 minutes until a golden crust forms.
- Carefully flip the fillets and cook for a further 2–3 minutes, then transfer to a warm plate and tent loosely with foil.
- Reduce heat to medium and add butter to the same pan; once foaming, add the minced shallots and cook for 2 minutes until softened and translucent.
- Add the minced garlic and thyme sprigs and cook for 1 minute, stirring constantly to prevent burning.
- Deglaze the pan with white wine and lemon juice, scraping up any browned bits, and allow to reduce by half for about 2 minutes.
- Return the fillets to the pan and spoon the shallot garlic butter sauce over them continuously for 1–2 minutes to finish cooking and coat well.
- Plate the fillets, spoon remaining pan sauce over the top, and garnish generously with freshly chopped coriander. Serve immediately.
Tip: Wolffish has a naturally moist, dense texture — avoid overcooking by using the press test: the flesh should give slightly but spring back. Basting continuously in the final step ensures the fish stays succulent and absorbs all the aromatics from the pan.
