Preheat oven 325º (163ºC).
Microwave chicken broth and mushrooms in a partially covered bowl for 1 minute. Remove from microwave and allow to sit and soften, about 5 minutes. Pour mushrooms through a fine mesh sieve and reserve broth. Chop the mushrooms. Set aside.
In a large saute pan, over medium-low heat, add onions, garlic, chopped mushrooms, thyme, salt, and pepper, and saute until the onion is very soft and translucent about 12-15 minutes. Stir in Worcestershire Sauce, reserved chicken broth, and tomato paste and mix well. Remove from heat and cool.
In a large mixing bowl, combine the turkey, breadcrumbs, Parmesan, gelatin, eggs, and cooled onion mixture until well mixed. Shape into a rectangular loaf on a large rimmed baking sheet.
In a small mixing bowl, mix together ketchup, brown sugar, dried mustard, ginger, liquid smoke, and hot sauce. Spread the ketchup mixture evenly over the top and sides of the meatloaf.
Bake meatloaf in a preheated oven for 1 1/2 hours or until meatloaf reaches an internal temperature of 160 degrees (71ºC).
