Preheat the Oven: Set your oven to 425°F (220°C). Line a rimmed baking sheet with parchment paper and place a wire rack on top.
Prepare the Breading: In a shallow dish, combine panko breadcrumbs, Parmesan cheese, chopped parsley, garlic powder, salt, and pepper. Drizzle in olive oil and toss until the mixture is evenly coated.
Prepare the Egg Wash: In another shallow dish, beat the egg until well blended.
Coat the Salmon: Dip each salmon fillet into the egg wash, ensuring it's fully coated. Then, press the fillet into the breadcrumb mixture, covering both sides and the top.
Arrange on Baking Sheet: Place the coated salmon fillets onto the prepared wire rack. If there's any leftover breadcrumb mixture, sprinkle it over the top of the fillets.
Bake: Bake in the preheated oven for 10–15 minutes, or until the salmon is cooked through and the crust is golden brown. The internal temperature should reach 145°F (63°C).
Serve: Remove from the oven and let the salmon rest for a few minutes. Serve with lemon slices for added zest.
