Preheat oven to 400°F and line a baking sheet with parchment paper.
In a large bowl, combine turkey, breadcrumbs, egg, Dijon, maple syrup, garlic, onion powder, salt, and pepper.
Mix until just combined, don’t overwork it.
Roll into 1-inch meatballs and place on the baking sheet.
Lightly spray with oil. Bake for 15–18 minutes, or until golden and cooked through (internal temp 165°F).
While the meatballs bake, make the glaze: in a small saucepan over medium heat, whisk together cranberry sauce, maple syrup, Dijon mustard, apple cider vinegar, salt, and herbs.
Simmer for 5–6 minutes until glossy and slightly thickened.
Toss the baked meatballs in the cranberry glaze until coated.
Serve warm, topped with extra glaze, fresh thyme.
