Rehydrate the stuffing mix: Preheat oven to 375°F (190°C). Add the Stove Top stuffing mix and chicken broth to a large bowl. Let sit for 2–3 minutes until the stuffing softens and absorbs the liquid.
Add the aromatics and seasoning: Add diced onion, garlic, parsley, salt, and black pepper to the bowl. Stir to combine evenly.
Add the ground turkey: Add the ground turkey to the stuffing mixture. Mix gently until just combined, being careful not to overmix.
Make the ketchup glaze: In a small bowl, whisk together ketchup, brown sugar, Dijon mustard, and Worcestershire sauce until smooth. Set aside.
Shape the meatloaves: Line a baking tray with parchment paper. Divide the mixture into 2 meatloaves and shape evenly on the prepared tray.
Glaze and bake: Brush the meatloaves with half of the ketchup glaze. Bake for 30 minutes. Remove from the oven and brush with the remaining glaze. Return to the oven and bake another 15 minutes, or until the internal temperature reaches 165°F (74°C).
