Preheat oven to 400 degrees Fahrenheit.
Pat salmon dry; leave skin on for easier handling and remove bones if desired.
Season salmon with paprika, kosher salt, black pepper, and olive oil. Place in an oven-safe dish.
Bake salmon for 15-16 minutes (or 18-22 minutes if using a large piece) until it flakes easily and is opaque.
In a medium skillet, toast chopped pecans over medium heat in olive oil or ghee until fragrant and slightly darker.
Add maple syrup, orange juice, rosemary, kosher salt, and mustard to skillet. Simmer gently, stirring occasionally, until sauce thickens to coat a spoon.
If too thick after cooling, thin sauce with additional maple syrup.
Spoon maple pecan glaze over baked salmon. Garnish with fresh rosemary and sliced tangerines if desired.
Serve immediately and enjoy.
