Preheat your oven to 400ºF. Line a baking sheet with parchment paper for easy cleanup and place the salmon on the prepared sheet, skin-side down.
In a small bowl, mix together Dijon mustard, maple syrup, olive oil, kosher salt, paprika, and black pepper. Spoon half of this glaze over the salmon evenly.
Bake the salmon for 15 minutes in the preheated oven. Check for doneness; when you remove it, spoon the remaining glaze over the fish and return it to the oven for another 5 to 10 minutes or until an instant-read thermometer reads 145ºF.
Once cooked through, remove the salmon from the oven. Serve immediately and enjoy the delightful flavors of the maple mustard glaze.
Notes
Do not skip the glaze for the best flavor.
Fresh salmon makes a big difference.
Adjust cooking time based on thickness of the fish.
