• To start, preheat your oven to 400ºF (200ºC). Line a roasted tray with non-stick baking paper, or use a silicone mat.
• In a small mixing bowl, combine the herbs. Mix them well to ensure they are evenly distributed. Set it aside.
• Then, whisk together the melted butter, garlic cloves, and lemon juice. Set it aside as well.
• Next, place the tilapia fillets onto the lined roasting tray. Then, season them well with the spice and herb mix. Ensure they are coated on both sides.
• Place the seasoned tilapia fillets into the tray in a single layer. Brush the butter and garlic sauce over the fillets. They should be covered well. Finally, add some lemon slices in each fillet.
• Place the tray inside the heated oven and bake the fillets for 10-15 minutes. After 10 minutes, test the doneness of the fillets.
• Once finished, remove the baked tilapia from the oven and allow it to rest for 5 minutes. Then, serve it immediately with fresh chopped parsley.

Baking Whole Tilapia

• For whole tilapia, simply brush the inside of the fish with the garlic butter dressing. You can also stuff the fish if you'd like, or simply add lemon slices inside.
• Bake the whole tilapias for roughly 10 minutes per inch of thickness. If your tilapia is about 3 inches thick, bake it for about 30 minutes.
