Preheat your oven to 400°F (200°C). This will ensure the red snapper cooks evenly and achieves a perfect, flaky texture.
Rinse the red snapper fillets under cold water and pat them dry with paper towels. This helps remove any excess moisture, allowing the seasoning to stick better.
In a small mixing bowl, combine the olive oil, minced garlic, paprika, oregano, thyme, salt, and black pepper. Mix well until all the ingredients are evenly incorporated.
Using a basting brush, generously coat each red snapper fillet with the seasoning mixture. Make sure to cover both sides of the fillets. Let the fish marinate for about 5 minutes to absorb the flavors.
Place the seasoned fillets on a baking sheet lined with aluminum foil (optional for easy cleanup). Arrange lemon slices on top of the fillets, adding a citrusy zing to the dish.
Place the baking sheet in the preheated oven and bake for 12-15 minutes, or until the fish is opaque and flakes easily with a fork. The internal temperature should reach 145°F (63°C).
Once cooked, remove the red snapper from the oven and transfer it to serving plates. Garnish with freshly chopped parsley and serve with lemon wedges on the side.
Pair the red snapper with your favorite sides, such as roasted vegetables, rice, or a light salad, and enjoy a delicious, healthy meal.
