- Heat pancetta in a large Dutch oven or stock pot over medium heat. Sauté for 5-6 minutes until pancetta begins to crisp. Remove pancetta with a slotted spoon and set aside.
- Add carrots, celery and shallot to pot and sauté in the pancetta drippings for 3 minutes. Add garlic and continue to sauté 2 minutes longer.
- Add split peas, chicken stock, soy sauce, thyme sprigs, bay leaves and pepper. Bring to a boil and reduce heat to low. Cover with lid slightly cracked. Simmer soup for 1 hour or until peas have softened and broken down, stirring occasionally.
- While soup cooks, heat a medium skillet over medium heat. Add olive oil, panko, thyme, garlic powder and salt. Stir well to coat panko. Toast for 5-6 minutes, stirring regularly until the bread crumbs are a deep golden brown. Remove from heat and transfer to a small bowl.
- Remove thyme sprigs and bay leaves from soup. Ladle soup into bowls and serve hot, topped with a few spoonfuls of garlic herb panko, crispy pancetta, and additional fresh thyme.
