Cook the bacon in a large pot over medium heat until crispy, about 5-7 minutes.
Add the chopped onion and celery to the pot, sauté until softened, about 5 minutes.
Stir in the diced potatoes and thyme, cook for another 2-3 minutes.
Pour in the clam broth and bring to a gentle simmer, cooking uncovered for around 15 minutes or until the potatoes are tender.
Add the chopped clams and the heavy cream, simmer for an additional 5 minutes.
Season with salt and pepper to taste, and stir well to combine.
Serve hot, garnished with crispy bacon bits and chopped parsley.
