Preheat and prep: Heat your oven to 425°F (220°C).
Line a sheet pan with foil or parchment and lightly oil it. Pat the salmon dry with paper towels. Season both sides with salt and pepper.
Make the topping: In a bowl, mix the softened butter, olive oil, garlic, Parmesan, panko, parsley, lemon zest, paprika, and Italian seasoning.
Stir until it forms a spreadable paste.
Coat the salmon: Place the fillets on the prepared pan, skin-side down if using skin-on. Spread the garlic-parmesan paste evenly over the top of each fillet.
Roast: Bake for 10–12 minutes, depending on thickness. The topping should be lightly golden and the salmon should flake easily with a fork.
For deeper color, broil for 1–2 minutes at the end, watching closely.
Finish with lemon: Squeeze fresh lemon juice over the hot salmon. Rest for 2 minutes to let the juices settle.
Serve: Plate with your favorite sides and lemon wedges. Good options: garlic green beans, roasted asparagus, couscous, quinoa, or a simple arugula salad.
