The Steps of Preparation

1. Preheat the oven to 200°C (400°F) and line a baking dish with parchment paper or lightly grease it.
2. Pat the fillets dry with a paper towel to remove excess moisture, ensuring a perfect texture after baking.
3. In a small bowl, whisk together olive oil (or butter), lemon juice, garlic, paprika, oregano, black pepper, salt, and Dijon mustard.
4. Place the fillets in the baking dish and pour the marinade evenly over them, rubbing it in gently.
5. Allow the fillets to marinate for 15–30 minutes at room temperature (or cover and refrigerate for up to 2 hours for a deeper flavor).
6. Add the white wine or broth to the dish, helping to keep the fish moist while baking.
7. Arrange lemon slices on top of each fillet and sprinkle with fresh parsley.
8. Bake for 15–20 minutes, or until the fillets flake easily with a fork (internal temperature should reach 63°C or 145°F).
9. Remove from the oven and let rest for 2–3 minutes before serving.
10. Garnish with additional fresh herbs and a final squeeze of lemon juice for the perfect finishing touch.
