Pat fillets dry and place on paper towels; let rest for 10 minutes, then season both sides with 0.25 teaspoon kosher salt and 0.25 teaspoon black pepper.
Cooking
Heat olive oil in a large skillet over medium-high until shimmering, about 1 minute.
Add fillets and cook undisturbed for 4 minutes, until golden and sizzling gently.
Flip fillets, add butter to the pan, and cook another 2–3 minutes, until opaque and flaky.
Push fish aside, add garlic and cook 30 seconds until fragrant.
Stir in lemon juice and parsley, swirl sauce, then spoon over fillets.
Notes
Personal testing note: resting fillets on paper towels for 10 minutes gave a crisp crust.Personal testing note: basting fish with butter at the end builds extra flavor and shine.Personal testing note: storing leftover fillets in their pan sauce helps them reheat moist.
