Preheat oven to 425°F. For easy cleanup, line your baking sheet pan or baking dish with aluminum foil.
Pat the pork tenderloin dry with paper towels. Sprinkle seasoning salt and flaky poultry seasoning evenly on all sides.
Lay bacon slices out on a cutting board in one row, slightly overlapping.
Place the pork tenderloin on top. Wrap the bacon around the pork tenderloin, securing with toothpicks. Place on the foil-lined sheet pan or baking dish.
Bake uncovered in the preheated oven 20-25 minutes. Remove from the oven, and brush with 1/2 cup of the glaze. Place back in the oven. Bake 5-10 minutes or until an internal temperature of 130-135°F is reached.
Carefully remove from the oven. Remove the toothpicks. Using tongs, flip over the tenderloins. Brush 1/2 cup more of the glaze over the entire exterior. Place back in the oven and bake an additional 5-10 minutes or until an internal temperature reaches about 140°F. Broil 1-3 minutes to crisp the bacon. The pork should reach an internal temperature of 145°F when finished.
Remove from the oven. Brush 1/2 cup more of the glaze over the pork. Rest for 3 minutes. Slice pork into medallions and serve with extra glaze on the side.
