Rub the 4 salmon fillets with 1 teaspoon garlic powder, Kosher salt and pepper, and 1 tablespoon olive oil.
Place the filets in a rectangular baking dish and bake for 12-15 minutes, or until flaky.
Meanwhile, in a small pan, heat the 1 tablespoon olive oil for the glaze over medium heat. Add the 2/3 cup pecans and cook, stirring often, until they start to darken, around 3-4 minutes.
Add the 1/3 cup maple syrup, 2 tablespoons apple cider vinegar, and 1 tablespoon Dijon mustard. Allow the sauce to bubble for 3-4 minutes, until it thickens to coat the back of a spoon.
Once the salmon is done baking, remove from the oven and spoon over the maple pecan glaze.
Garnish with freshly chopped parsley, if desired.
Notes
Storing leftovers: Store leftover salmon in an airtight container in the fridge. It will keep fresh for up to about 3 to 4 days.
To reheat: Place salmon in a dish in the oven for about 10 minutes at 300 degrees Fahrenheit. This will help keep the outside crispy but the inside tender and flaky!
