01 - Set the oven to 425°F and prepare a baking sheet by lining it with parchment paper or greasing lightly.
02 - Place cod fillets skin-side up on the baking sheet and thoroughly pat the skin dry using paper towels to ensure crispiness.
03 - Brush each fillet’s skin side lightly with olive oil; season both sides evenly with sea salt and black pepper.
04 - Arrange lemon slices, thyme sprigs, and garlic slices around the fillets—avoid placing them on the skin side.
05 - Bake in the center of the oven for 12 to 15 minutes until the fish is opaque, flakes easily with a fork, and skin is golden and crisp.
06 - Carefully lift the fillets with a thin spatula to keep the skin intact; garnish with chopped parsley and serve immediately with lemon wedges.
