How to Make It
Preheat the oven to 400°. Set the salmon fillets on a rimmed baking sheet and rub all over with 1 tablespoon of the olive oil; season with salt and pepper. Roast for 10 minutes, until the salmon is just cooked through.
Meanwhile, in a blender, puree the basil with the parsley, anchovies, lemon zest and juice, capers, garlic and the remaining 1/2 cup of olive oil until smooth; season with salt. Serve the basil sauce with the salmon.
