01 - Preheat the oven to 400°F. Line a baking sheet with parchment paper or lightly grease it.
02 - Pat salmon fillets dry with paper towels and season both sides with salt and pepper. Arrange fillets evenly on the prepared sheet.
03 - In a small bowl, combine basil pesto, grated Parmesan, gluten-free breadcrumbs, and olive oil. Mix until a coarse, moist paste forms.
04 - Spoon the pesto mixture evenly over the tops of the salmon fillets, pressing gently to adhere.
05 - Bake the salmon for 12 to 15 minutes, until just cooked through and flakes easily with a fork.
06 - Remove salmon from oven and let rest for 2 minutes. Serve hot, garnished with lemon wedges and fresh basil if desired.
