Step 1: 2 hours or day before: Make marinade: Zest 1/2 of an orange and squeeze out juice. Place in a small bowl and add the remaining ingredients. Mix well. Save the other 1/2 of an orange for later.
Step 2: Place the onions evenly in a deep baking pan. Place the pork over the onions and pour over the marinade. Top with the orange slices.
Step 3: Let marinade at least 2 hours or overnight in refrigerator.
Step 4: When ready to cook, preheat oven to 350 degrees F. Remove the pork from the refrigerator at least 20 minutes before cooking.
Step 5: Cook for about 1 hour, then coat pork with the pan drippings. Cook for about 15-20 minutes longer. Check temperature with meat thermometer which should read about 145-160 degrees F before removing from oven, depending on your level of temperature choice.
Step 6: Let sit for 10 minutes before slicing. Reserve the drippings and place the sliced pork back into the pan with the drippings. Serve the onions and sauce over the pork.
