Preheat oven to 375°F. Line a rimmed baking sheet with foil and spray with nonstick spray.
In a medium bowl, stir stuffing mix with 1 cup broth. Let sit 5 minutes to soften. If it still looks dry, add broth 1 tablespoon at a time.
In a skillet over medium heat, sauté onion and celery for 3 to 4 minutes until softened. Add garlic and cook 30 seconds. Remove from heat to cool slightly.
In a large bowl, combine ground turkey, hydrated stuffing, sautéed vegetables, eggs, ketchup, Worcestershire sauce, thyme, poultry seasoning, salt, and pepper. Mix gently just until combined.
Shape mixture into a loaf on the prepared baking sheet (about 10×4 inches). Bake 35 minutes.
Stir together glaze ingredients. After 35 minutes, spread half the glaze over the meatloaf. Bake 10 minutes.
Brush on remaining glaze. Bake another 10 to 15 minutes, or until the center reaches 165°F.
Rest 10 minutes before slicing and serving.
