Preheat oven to 400℉. Line the bottom of a loaf pan with a slice of bread to soak up the grease during cooking.
In a small skillet heat the olive and sauté onions over low-medium heat for 5 minutes. Add garlic, thyme, rosemary, salt and pepper. Add the Worcestershire sauce. Mix well.
Combine the ground turkey, bread crumbs, egg, ketchup and onion mixture in a large bowl. Mix well. Form into a loaf and place in the loaf pan.
Bake for 1 hour until meatloaf is cooked through.
Let stand 10 minutes before slicing. Serve with extra ketchup if desired.
