Recipe Overview
- Prep Time: 15 minutes
- Cook Time: 35–45 minutes
- Servings: 2–3 portions
Ingredients
For the Fish & Vegetable Bed:
- 2 whole fresh fish (sea bass, sea bream, or tilapia, cleaned and scaled)
- 2–3 medium potatoes, peeled and cut into round slices
- 2 medium ripe tomatoes, cut into round slices
- 1 fresh lemon, cut into round slices
- 2–3 sprigs fresh rosemary (or dried rosemary)
- 2 tbsp fresh parsley, finely chopped
For the Citrus Garlic Marinade:
- 2–3 tbsp extra virgin olive oil
- 3 cloves garlic, minced
- Juice of 1 fresh lemon
- 1 tsp paprika
- ½ tsp freshly ground black pepper
- ½ tsp chili powder (optional, for gentle heat)
- 1 tsp salt (or to taste)
Step-by-Step Instructions
1. Preheat and Layer Vegetables
Preheat your oven to 180°C (350°F). Lightly grease a baking dish or roasting tray with olive oil. Layer the potato slices evenly across the bottom, then arrange the tomato slices directly over the potatoes to form a juicy vegetable base.
2. Place Fish and Herb Garnish
Score the cleaned whole fish with a few shallow diagonal slashes on both sides. Place the fish directly on top of the tomato and potato layer. Tuck fresh lemon slices and rosemary sprigs around and inside the fish cavities.
3. Prepare the Marinade Sauce
In a small bowl, whisk together the extra virgin olive oil, minced garlic, lemon juice, paprika, salt, freshly ground black pepper, and chili powder until well emulsified.
4. Pour and Season
Pour the garlic-citrus marinade evenly over the fish, potatoes, and tomatoes, ensuring the liquid flows into the slashes and coats the vegetables underneath.
5. Bake Covered, Then Roast Uncovered
Cover the baking dish tightly with aluminum foil. Bake in the preheated oven for 25 to 30 minutes until the potatoes are tender. Remove the foil and return the dish to the oven for an additional 10 to 15 minutes, or until the fish skin is lightly golden and crisp around the edges.
6. Garnish and Serve
Remove from the oven, garnish with fresh chopped parsley, and serve hot directly from the baking dish!
Helpful Cooking Tips
- Slice Potatoes Thinly: Keep potato slices around ¼-inch thick so they cook completely in the steam generated under the foil.
- Score the Fish: Slashing the fish skin allows the lemon-garlic marinade to penetrate deep into the meat for maximum flavor.
- Keep Moisture Sealed: Ensure the foil is sealed tightly around the baking dish so the tomatoes release their juices and steam the fish without drying it out.
Tasty Customization Ideas
- Add More Veggies: Layer sliced bell peppers, zucchini, or black olives alongside the tomatoes for extra Mediterranean flavor.
- Herb Twist: Substitute rosemary with fresh oregano, dill, or coriander to complement the lemon marinade.
- White Wine Accent: Add 2 tablespoons of dry white wine to the olive oil mixture for an elevated seafood sauce base.
Serving Suggestions
Serve this Baked Citrus Whole Fish hot alongside a crisp Greek salad, warm pita bread, or steamed white rice to soak up the garlic-lemon pan juices!
