Key Ingredients for Baked Whole Tilapia
You'll find the exact measurements in the recipe card, but here's a closer look at a few of the ingredients and why I use them.
- Whole Tilapia with Aromatics: A fresh medium tilapia is always my choice. I love how scoring it lets the lemon slices, garlic cloves, and bay leaves infuse every bite with flavor.
- Seasoning: Salt and black pepper may be simple, but for me, they're essential; they wake up the natural taste of both the fish and the vegetables.
- Potatoes and Onion: Roasted potatoes with onion are the heart of this dish. I look forward to them every time because they soak up all those savory juices.
- Olive Oil and Sherry Wine: A drizzle of extra virgin olive oil and a splash of sherry wine are what make this recipe shine, rich, slightly sweet, and full of depth.
How to Make Baked Whole Tilapia
You can find the complete printable recipe with measurements below, but for now, here's a quick overview of how it goes:
1. Prepare the Tilapia: Make diagonal cuts on both sides of the tilapia so it cooks evenly, then rub it with salt and pepper, including inside the cuts. Stuff the cavity with lemon slices, garlic, and bay leaves, then refrigerate while you prepare the potatoes.
2. Start the Potatoes: In a baking dish, mix the diced potatoes and onion with salt, pepper, extra virgin olive oil, and sherry wine. Bake in a oven at 400°F / 200°C (355°F convection / 180°C fan) for 40 minutes.
3. Add the Fish: Place the seasoned tilapia over the potato mixture, then pour the extra sherry and extra virgin olive oil over the fish.
4. Bake and Serve: Return the dish to the oven and bake for 30 more minutes, or until the fish is cooked through and the potatoes are golden. Serve with fresh herbs, if desired, alongside the sherry potatoes and onions.
My Tips for Juicy Whole Tilapia
Let the Fish Rest After Baking: Once out of the oven, I like to let the baked tilapia rest for 5-10 minutes. It helps the juices settle and makes the fish easier to serve.
Choose the Right Pan: I use a large, shallow baking dish so the fish and potatoes aren't crowded. It helps everything roast instead of steaming.
Watch the Liquid Level: If the wine evaporates too quickly while baking, I sometimes drizzle a little warm water or broth over the potatoes to keep them moist.
What to Serve with Baked Whole Tilapia
This baked whole tilapia is wonderfully easy and turns out incredibly juicy, especially alongside the flavorful baked potatoes and onions. I like to serve it with warm ciabatta or garlic bread to soak up the juices, and sometimes add a fresh salad. For dessert, chocolate mousse or tiramisu makes the perfect finish.
