Preheat your oven to 400°F (200°C). In a medium bowl, combine the panko breadcrumbs, parmesan, lemon zest, garlic, half of the salt, black pepper, and olive oil.
⅓ cup panko breadcrumbs, ⅓ cup shredded or grated parmesan cheese, ½ lemon, zested, ½ teaspoon granulated garlic, 1 teaspoon Morton kosher salt, divided*, freshly ground black pepper, 1 teaspoon olive oil
Line a baking sheet with parchment paper. Place the salmon filets on the prepared baking sheet. Pat each side dry with a paper towel.
2 6- ounce salmon filets, thawed
Season both sides of the salmon filets with the remaining salt and black pepper.
Using the back of a spoon, spread the Dijon mustard evenly on the top of the skinless sides of each filet.
1 heaping Tablespoon Dijon mustard
Press the panko mixture firmly onto the mustard-coated tops of the filets, creating a thick, even layer.
Bake in the preheated oven for 10-12 minutes, or until the fish reaches an internal temperature of 145°F (63°C) and the topping is golden.
