01 - Rinse split peas thoroughly under cold water and set aside for later use.
02 - In a large pot or Dutch oven, heat a small amount of cooking oil over medium heat. Add the diced onion, carrots, and celery. Sauté for approximately 5 minutes, or until the vegetables have softened.
03 - Stir in the minced garlic and continue to cook for 1 minute until fragrant.
04 - Add the rinsed split peas, ham hock (or diced ham), chicken broth, bay leaves, thyme, and black pepper to the pot. Stir well to ensure all ingredients are evenly distributed.
05 - Bring the mixture to a rolling boil over high heat. Once boiling, reduce the heat to low, cover the pot, and let it simmer for 1 hour, stirring occasionally to prevent sticking.
06 - Remove the lid from the pot and continue to simmer for an additional 20 to 30 minutes, or until the split peas have become tender and the soup has reached the desired consistency.
07 - Carefully remove the ham hock from the soup. Shred any edible meat from the bone and return the shredded meat to the soup. Discard the ham bone and bay leaves. If using pre-diced ham, this step can be omitted.
08 - Taste the soup and adjust the seasoning with salt and additional black pepper as needed to achieve your preferred flavor profile.
09 - Ladle the hot soup into bowls. Garnish with chopped fresh parsley and extra cracked black pepper, if desired.
