Heat each flat side of burger buns in an oiled skillet for at least 30 seconds. Set aside. Gently place one ground pork burger patty in the heated skillet over medium heat and sear one side for 3 to 5 minutes or as it turns slightly golden brown.
Slowly flip burger patty and cook for another 3 to 4 minutes or to your desired doneness. Transfer to a paper-lined plate. Do the remaining ground pork burger patties. Let the patties rest for at least 5 minutes.
