Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper for easy cleanup.
Pat the orange roughy fillets dry with paper towels. This helps them to brown nicely and prevents a watery texture.
In a small bowl, whisk together the olive oil, lemon zest, lemon juice, minced garlic, oregano, thyme, salt, and pepper. This creates your vibrant flavor base.
Arrange the orange roughy fillets on the prepared baking sheet, ensuring they have a little space between them.
Spoon the lemon-herb mixture evenly over the top of each fillet, making sure to coat them generously.
Bake for 10-15 minutes, or until the fish is opaque and flakes easily with a fork. The exact cooking time will depend on the thickness of your fillets.
Remove from the oven and garnish with fresh chopped parsley and serve immediately with lemon wedges on the side.
