Creating Irresistibly Crispy Parmesan Salmon Bake is straightforward if you follow these simple steps:

1. Preheat the Oven: Begin by preheating your oven to 400°F (200°C).
2. Prepare the Baking Dish: Lightly grease a baking dish with cooking spray or a thin layer of olive oil.
3. Mix the Topping: In a bowl, combine the grated Parmesan cheese, breadcrumbs, garlic powder, onion powder, salt, and black pepper. Mix well until combined.
4. Prepare the Salmon: Pat the salmon fillets dry with a paper towel. This helps the topping adhere better.
5. Apply Dijon Mustard: Spread a thin layer of Dijon mustard over the top of each salmon fillet.
6. Coat with Topping: Press the parmesan-breadcrumb mixture onto the mustard-covered salmon, ensuring an even layer.
7. Drizzle with Olive Oil: Lightly drizzle olive oil over the coated salmon to enhance the crispiness.
8. Bake: Place the baking dish in the preheated oven and bake for 15-20 minutes or until the salmon is cooked through and the topping is golden brown.
9. Garnish: Once baked, remove the dish from the oven and let it rest for a few minutes. Garnish with fresh parsley if desired.

This simple yet effective method ensures a delightful dish that captures the essence of the Irresistibly Crispy Parmesan Salmon Bake.
