Tilapia is a wonderfully versatile fish, with mild firm flesh that can be prepared in many ways. This easy baked preparation tops the fillets with a savory blend of butter, chopped olives, capers and a hint of garlic.
Preheat the oven to 400°F. Line a baking sheet with foil and oil the foil. Put the butter in a small bowl and mash it with a fork to soften. Add the olives, capers and a pinch of garlic powder with salt and pepper to taste. Stir well to blend. Form the butter in discs about 1-½-inch across on a piece of foil and refrigerate until solid. (The butter can be prepared up to 2 days in advance). Set the tilapia fillets on the baking sheet and season with garlic powder, salt and pepper. Bake until opaque through the thickest part 6-8 minutes. To Serve: Transfer the tilapia fillets to individual plates and top each with a disc of olive-caper butter, which will melt and coat the fillets.
