When you need dinner on the table fast with minimal cleanup, baked tilapia is your best friend. This recipe takes mild, affordable tilapia and elevates it with a quick lemon garlic butter sauce that keeps the fish incredibly moist while adding layers of bright, savory flavor.
Everything goes into one baking dish, making this practically a sheet-pan dinner. The tilapia bakes in a pool of melted butter, garlic, and lemon juice, basting itself as it cooks. In 15 minutes, you have perfectly flaky fish with a built-in sauce. Pair it with steamed broccoli and rice for a complete meal that even the pickiest eaters will love.
