Place the bacon in a medium pot and turn the heat to medium. Cook the bacon until it’s beginning to crisp, about 5 minutes. Add the onions and season with a little bit of salt and fresh black pepper. Cook, stirring, until the onions are softened, about 5–6 minutes.
Sprinkle flour and ranch seasoning mix into the pot. Cook, stirring frequently, for 1 minute. Pour in the strained clam juice from the can, 2 bottles clam juice and chicken broth.
Add the potatoes and bring to a boil, stirring occasionally while scraping the bottom and sides of the pan. Reduce the heat to medium-low and simmer, stirring occasionally, until the potatoes are tender, about 15 minutes.
Stir in the drained clams and cream and bring back to a simmer. Taste and add salt, if needed. Serve hot, garnished with chopped parsley.
