In a shallow dish, whisk together the olive oil, lemon zest, lemon juice, garlic, Dijon mustard, thyme, salt, and pepper. Add the salmon fillets and turn a few times to coat the salmon well with the marinade. Refrigerate for 20–30 minutes.
Preheat the oven to 400°F. Line a baking sheet with parchment or lightly oil it. Place the salmon skin-side down, spooning extra marinade over the top. Bake 12–15 minutes, until the salmon flakes easily with a fork and reaches an internal temperature of 125–130°F.
Sprinkle with fresh parsley and serve with lemon wedges.
