How long you bake Tilapia for will depend on the thickness of the fish that you use, but an ideal way of telling whether any fish is cooked is by sticking a pointed, sharp bladed knife into the thickest part. Place the tip of the knife against your lips and if it is hot then the fish is cooked.

Your oven will need to be pre-heated to 190 degrees centigrade (375 degrees Fahrenheit).
Take an oven proof baking dish and oil it; if you prefer you can use a non stick cooking spray. This will reduce the amount of calories that are in the overall dish.
Wash the tilapia fillets under cold water, taking care that it does not splash onto utensils or work surfaces. If it does, you must wash them down because there is a risk that harmful bacteria will be spread in this manner. (This is true of any raw fish or meat; harmful bacteria that are on the surface will be rendered harmless by the cooking process).
Once the fillets have been washed, pat them dry with paper towels. They can then be placed into the baking dish and you can pour the lemon juice over them. The butter should be drizzled over the top of the fish, and then the garlic, parsley and pepper can be added.
Place the baking dish with the fish and other ingredients into the preheated oven and bake until the fish is white and flaky when it is pulled apart by a fork, which should take about 30 minutes.
If you want to test it sooner, try the knife method that is described above.
