Step 1

Preheat oven to 425 degrees F. Line a large rimmed baking sheet with parchment paper.

Step 2

Combine mustard, garlic, lemon zest, lemon juice, rosemary, honey, salt and crushed red pepper in a small bowl. Combine panko, walnuts and oil in another small bowl.

Step 3

Place salmon on the prepared baking sheet. Spread the mustard mixture over the fish and sprinkle with the panko mixture, pressing to adhere. Lightly coat with cooking spray.

Step 4

Bake until the fish flakes easily with a fork, about 8 to 12 minutes, depending on thickness.

Step 5

Sprinkle with parsley and serve with lemon wedges, if desired.
