Oven-baked red snapper is a simple, flavorful dish perfect for a healthy meal. Preheat the oven to 200°C (400°F). Clean and pat dry a whole red snapper, then score the sides. Rub with olive oil, salt, pepper, and your choice of herbs like thyme or parsley. Stuff the cavity with lemon slices and garlic. Place on a baking tray and bake for 20–25 minutes until the fish is cooked through and flaky. Serve hot with vegetables or rice for a complete meal.
