Step-by-Step Instructions
1. Prepare Your Ingredients
Preheat your oven to 400°F (200°C). Wash and cut your potatoes, mince the garlic, and chop the fresh oregano. This initial preparation makes the cooking process smooth and enjoyable.
2. Season the Potatoes
In a large bowl, toss the potato rounds with 1 tablespoon of olive oil, half of the minced garlic, half of the chopped oregano, salt, and pepper. Ensure the potatoes are evenly coated for optimal flavor. Spread them in a single layer on a baking sheet.
3. Start Baking the Potatoes
Bake the potatoes for 20 minutes in your preheated oven. This gives them a head start, ensuring they are tender when the fish is ready. While they bake, you can prepare the sea bass.
4. Season the Sea Bass
Pat your sea bass fillets dry with paper towels. Season both sides with salt and pepper. In a small bowl, combine the remaining olive oil, minced garlic, and oregano, along with the juice from half a lemon.
5. Add Sea Bass and Finish Baking
After the potatoes have cooked for 20 minutes, carefully remove the baking sheet from the oven. Place the seasoned sea bass fillets among the potatoes. Drizzle the lemon-oregano mixture over the fish and potatoes, and place the lemon slices on top of the fish. Return the baking sheet to the oven and bake for another 10-15 minutes, or until the fish is cooked through and flakes easily with a fork. This completes your delicious Mediterranean dinner recipe.
Variation Ideas
- Add Vegetables: Toss in bell peppers, zucchini, or cherry tomatoes with the potatoes for extra nutrition and color.
- Spicy Kick: A pinch of red pepper flakes can add a subtle heat to the dish.
- Herb Swap: Experiment with other fresh herbs like thyme or dill instead of oregano.
Storage Instructions
Store any leftover baked sea bass and potatoes in an airtight container in the refrigerator for up to 2-3 days. Reheat gently in the microwave or oven until warmed through. Avoid overcooking to maintain the fish’s tenderness.
