Garlic Butter Baked Tilapia - Flaky and Full of Flavour

Baked tilapia is one of my favourite quick dinners, and this garlic butter version is the one I make most often. The sauce is a simple mix of melted butter, fresh garlic, lemon juice, paprika, and parsley, but it turns mild white fish into something rich, flaky, and full of flavour in just 20 minutes. Everything goes into one pan, there's no flipping, no splattering, and no complicated technique. The garlic butter soaks right into the fish as it bakes, so every bite is savoury and tender all the way through.
