Prep the fish: Pat tilapia dry on both sides. Season with salt, pepper, and paprika.
Heat the pan: Set a large skillet over medium-high heat.
Add olive oil and let it shimmer.
Sear the tilapia: Place fillets in the pan without crowding. Cook 2–3 minutes until edges turn opaque and the underside is golden.
Flip and finish: Gently flip. Cook 1–2 more minutes, until the fish flakes easily with a fork.
Transfer to a plate and tent loosely with foil.
Make the sauce: Lower heat to medium. Add butter to the same skillet. When melted and foamy, add garlic.
Cook 30–45 seconds until fragrant, stirring so it doesn’t brown.
Brighten: Stir in lemon juice and zest. Scrape up browned bits from the pan for extra flavor.
Combine: Return the fish to the skillet for 20–30 seconds, spooning sauce over the top. Sprinkle with parsley.
Serve: Plate fillets, pour over more sauce, and add lemon wedges on the side.
