This baked whole tilapia is cooked to perfection with golden potatoes and a splash of sherry wine. It’s a simple one-pan meal that stays juicy, flavorful, and wonderfully fresh.
Score the tilapia with diagonal cuts on both sides for even cooking. Rub the fish with salt and black pepper, making sure to season inside the cuts.
Insert lemon slices, garlic cloves, and bay leaves into the cavity of the fish. Refrigerate the fish.
In a baking dish, toss diced potatoes and sliced onion with salt, black pepper, 2 tablespoons extra virgin olive oil, and 80 ml sherry wine.
Bake the potato mixture in a preheated oven at 400°F /200°C (355°F convection / 180°C fan) for 40 minutes.
Place the seasoned tilapia on top of the baked potatoes. Drizzle 40 ml sherry wine and 2 tablespoons extra virgin olive oil over the fish.
Return the dish to the oven and bake for another 30 minutes, or until the fish is cooked through and the potatoes are golden.
Serve hot with the sherry-flavored potatoes and onions, garnished with fresh herbs if desired.
Notes
Score the Fish Well: I like to make 3–4 deep diagonal cuts on each side of the whole tilapia so it cooks evenly and soaks up all the seasoning.Stuff Generously: I always tuck the lemon slices, garlic, and bay leaves firmly inside the cavity; it makes the whole tilapia fish smell amazing while it bakes.Toss the Potatoes Thoroughly: I give the potatoes and onion a good mix with the extra virgin olive oil and sherry wine so every piece is coated and roasts evenly.Bake in Two Steps: I like to pre-bake the potatoes first; this way they come out perfectly golden without overcooking the fish.Chill the Fish Before Baking: I usually refrigerate the stuffed tilapia while the potatoes are in the oven. It gives the flavors time to settle into the tilapia.
