Heat a large sautee pan over medium-low heat. Add olive oil and sautee onions, garlic and thyme for about 15 minutes. Set aside to cool.
In a medium bowl add turkey, egg, ketchup, chicken stock, breadcrumbs, carrots, worcestershire sauce and S & P. Add cooled onion mixture and mix together with your hands - do not overmix!
Line a sheet pan with parchment paper. Drop turkey mixture on the parchment paper and shape into a rectange loaf. Bake for approximately 55 minutes, or until internal temperature reaches 160 degrees on a meat thermometer.
**Note - Place a pan of water on the rack below the meatloaf in the oven to keep meatleaf from cracking.
