This is about as simple as it gets when it comes to salmon recipes. Some salmon, seasoning and a sheet pan is about all you need. If you are stuck for how to cook your salmon, baked salmon fillets are a great go-to option.
With a sharp knife, make about 4-5 slits in the salmon. Pat both sides of the salmon dry on both sides with paper towels. Season both sides with salt and pepper. Place skin side down on the baking sheet.
In a small pan over medium heat, combine butter, minced garlic, onion powder, cayenne pepper, and parsley. Stir for about a minute to combine and set aside to cool for ~5 minutes. Add the lemon juice.
Brush the salmon with the butter mixture covering the salmon completely.
Bake until cooked through and slightly flaky, about 10-15 minutes depending on thickness.
