Preheat your oven to 400°F and line a rimmed baking sheet with parchment paper for easy cleanup.
Grate the zucchini using the large holes of a box grater and place it in a clean kitchen towel, squeezing firmly to remove as much excess moisture as possible.
In a large mixing bowl, combine the ground pork, egg, squeezed zucchini, garlic powder, onion powder, sea salt, black pepper, and chopped parsley.
Mix the ingredients by hand until just combined, being careful not to overwork the meat to ensure the patties remain tender.
Form the mixture into four even patties, approximately one inch thick, and place them on the prepared baking sheet with space between each.
Lightly brush the tops of each patty with the olive oil to help achieve a golden, crispy finish during the baking process.
Bake for 15 to 18 minutes, flipping the patties halfway through, until the internal temperature reaches 160°F and the edges are beautifully browned.
