01 - Preheat the oven to 400°F. Line a baking sheet with parchment paper or lightly grease it with olive oil.
02 - In a small bowl, whisk together the maple syrup, Dijon mustard, olive oil, lemon juice, salt, and pepper until well combined.
03 - In a separate bowl, combine the chopped pistachios, panko breadcrumbs, lemon zest, and parsley. Toss until evenly mixed.
04 - Pat the salmon fillets dry with paper towels and arrange them on the prepared baking sheet, leaving space between each piece.
05 - Brush each salmon fillet generously and evenly with the maple-mustard glaze using a pastry brush, coating the entire top surface.
06 - Spoon the pistachio mixture onto the glazed surface of each fillet and gently press down with your hands to adhere the crust firmly.
07 - Bake in the preheated oven for 15 to 20 minutes, until the salmon is opaque throughout, flakes easily with a fork, and the crust is golden brown.
08 - Remove from the oven and serve immediately alongside roasted vegetables, quinoa, or a fresh green salad.
