Step 1

Drain clams through strainer set over medium bowl. Add bottled clam juice to drained liquid to measure 5 cups (add water if necessary). Bring potatoes, clam juice, bay leaves, and thyme to boil in medium saucepan over high heat. Reduce heat to low to maintain gentle simmer.

Step 2

While potatoes are coming to boil, cook bacon in large Dutch oven over medium heat until just crisp, 5 to 7 minutes. Add onion and cook until softened, about 5 minutes. Add garlic and cook until fragrant, about 30 seconds. Stir in flour and cook for 1 minute.

Step 3

Pour potatoes and cooking liquid into pot with onion mixture, using wooden spoon to scrape bottom of pan. Add clams, cream, and parsley and simmer until potatoes are tender, 5 to 7 minutes. Season with salt and pepper. Serve.
