Preheat the oven to 400°F (200°C). Lightly grease a baking dish or line it with parchment paper.
In a mixing bowl, combine the panko breadcrumbs, chopped dill, olive oil, garlic powder, salt, and black pepper. Mix well until the breadcrumbs are evenly coated.
Pat the salmon fillets dry with a paper towel and place them in the prepared baking dish, skin-side down.
Brush the top of each salmon fillet with Dijon mustard, ensuring an even layer.
Press the panko-dill mixture onto the mustard-coated side of each fillet, creating a crust.
Bake in the preheated oven for about 15-20 minutes, or until the salmon is cooked through and flakes easily with a fork.
Remove from the oven and let it rest for a few minutes. Serve with lemon wedges on the side.
