Light a grill or preheat a grill pan. Brush the onion with oil and grill until charred and softened, about 5 minutes. Brush the cut sides of the buns with oil and grill until toasted.
Form the ground turkey into four 1-inch-thick patties and brush with oil. Season with salt and pepper and grill over high heat for about 1 minute, turning once, until nearly cooked through.
Top with the Gouda, close the grill, and cook for 1 more minute until the cheese is melted and the burgers are cooked through.
Meanwhile, in a small bowl, combine the mustards, horseradish, and honey and spread on the bottom half of the buns. Top with the burgers and onions. Close the burgers and serve right away.
