Preheat oven to 400 degrees. Dry fish fillets well. Add them to a baking dish or sheet pan oiled with extra virgin olive oil.

Combine salt, pepper and paprika in a small dish. Dust the seasoning mixture over the fish, ensuring a good amount of seasoning on the thickest part of the fillet. Add thinly-sliced lemon to the dish.

Bake seasoned tilapia fillets for 10-14 minutes, depending on thickness of the fish. If using an instant-read thermometer, the fish should be nearing 145 degrees internally. 

Garnish with diced parsley and serve!
