Pat salmon dry with a paper towel and place salmon on a parchment lined baking sheet.
Combine the paprika, salt, garlic powder, dried mustard, onion powder, and black pepper in a small bowl. Drizzle the salmon with 2 tablespoons of olive oil. Sprinkle the seasoning mix over the salmon.
Cut half the lemon into thin slices and place over the salmon. Bake for 22 to 25 minutes or until the internal temperature reaches 145 degrees F on an instant read thermometer and the salmon flakes apart.
Juice the other half of the lemon and combine with the remaining tablespoon of olive oil and chopped parsley. Stir to combine.
Remove the salmon from the oven and top with the olive oil parsley mixture. Serve immediately.
