Preheat your oven to 375°F (190°C) and line a baking sheet with parchment paper.
In a large skillet over medium heat, add olive oil, then sauté the chopped onion and celery until they are soft and translucent, about 5 minutes.
In a large mixing bowl, combine the ground turkey, sautéed onion and celery, cubed bread, cranberries, parsley, thyme, sage, garlic powder, and salt and pepper.
Pour in the beaten egg and chicken broth, mixing everything gently with your hands or a spatula until well combined, being careful not to over-mix.
With your hands, form the mixture into small balls, about 1-2 inches in diameter, and place them on the prepared baking sheet.
Drizzle a little olive oil over the tops of the stuffing balls for added moisture and crispiness during baking.
Bake in the preheated oven for 25-30 minutes, or until the balls are golden brown and cooked through.
Remove from the oven and let cool for a few minutes before serving.
Notes
Serve on a festive platter lined with fresh parsley or alongside homemade cranberry sauce.
