You'll want to roast your white fish fillets hot and fast at 425°F (220°C) so they stay wonderfully tender instead of drying out. Keep in mind that how thick your fish cuts are matters way more than watching the clock: you're just looking for opaque flesh that flakes effortlessly.

Gently warm your minced garlic right in melted butter, then pull the pan off the heat before stirring in the lemon zest so that vibrant citrus perfume stays intact. Nestling the fillets right over fresh lemon slices and drenching them in garlic butter before the bake is the secret trick - the slices keep the fish lifted off the bottom while infusing bright flavor straight through.
