Fish Fillet With Garlic Sauce Recipe

Prepare fish

Pat the fish fillets dry with paper towels. Season both sides with 1 tsp kosher salt and 1/2 tsp black pepper. Place fillets on a plate or shallow dish.

Marinate briefly: Drizzle 2 tablespoons lemon juice and 1 tablespoon olive oil over the fillets and let sit at room temperature for 10 minutes while you prepare the sauce. This brightens flavor and helps lightly firm the flesh.

Minced aromatics

While fish marinates, finely mince the garlic cloves and shallot. Chop parsley and measure capers, wine (or broth), and lemon juice.

Cook aromatics

In a small saucepan or skillet over medium-low heat, melt 3 tbs butter with 1 tbs extra-virgin olive oil. Add the minced garlic and shallot and cook gently, stirring, until fragrant and softened but not browned, about 2–3 minutes. Keep heat moderate to avoid burning the garlic.

Deglaze and finish

Increase heat to medium, add 1 tbs white wine (or chicken broth) to deglaze the pan, scraping any bits from the bottom. Let the liquid reduce by half, about 1–2 minutes. Stir in 1 tbs lemon juice, 1 tsp capers (if using), 2 tbs chopped parsley, and 1/4 tsp red pepper flakes. Taste and season with salt and black pepper as needed. Keep sauce warm on lowest heat, do not boil once butter is incorporated.

Heat pan

Heat a large nonstick or stainless-steel skillet over medium-high heat. Add 2 tbs olive oil and 1 tbs butter. Let the butter foam and the oil shimmer but not smoke.

Sear fillets

Working in one layer (cook in two batches if necessary), place fillets presentation-side down (skin-side down if skin-on) in the hot pan. Press gently for 10 seconds to ensure even contact. Sear without moving until the edges look opaque and the underside is golden-brown, about 3–4 minutes depending on thickness.

Flip and finish

Carefully flip the fillets and reduce heat to medium. Spoon a little of the warm garlic sauce over each fillet and cook until the fish is opaque through and flakes easily with a fork, about 2–4 more minutes (internal temperature ~ 60–63°C / 140–145°F depending on preference). Remove fillets to a warmed plate.

Final sauce touch: If sauce has thickened or separated, rewarm gently and whisk in a small knob of butter (about 1 tbs) to gloss the sauce. Taste and adjust seasoning with salt, pepper, and a squeeze of fresh lemon if desired.

Plate: Spoon extra garlic sauce over each fillet. Garnish with additional chopped parsley and lemon wedges. Serve immediately with your choice of sides (rice, potatoes, or steamed vegetables).
