Pre-heat oven to 475°
In a small bowl, whisk lemon zest & juice, tangerine zest & juice, minced garlic, marmalade, salt & pepper, and olive oil then set aside.
Rinse and pat dry filets, place in a parchment lined baking dish and pour 3/4 of the citrus sauce over the top. Let marinade for 15 minutes, or up to 2 hours.
Bake fish until the tops have some color and fish begins to flake with a fork- about 10-14 minutes depending on the thickness of the filets.
Remove from oven and serve with the remainder of the sauce drizzled on top and fresh chopped parsley.
