Cook the bacon in the Dutch oven or soup pot over medium heat until just crisp. Drain on a paper towel-lined plate. Roughly chop or crumble the bacon.
You should have about 2 tablespoons of fat left in the pan. If not, add a bit of olive oil or avocado oil. If you have more than 2 tablespoons, pour the fat out into a small bowl and add 2 tablespoons of it back into the pot.
While the bacon is cooking, peel and dice the onion, dice the celery and peel and mince the garlic cloves.
Add the onion, celery and garlic, plus ¼ teaspoon fine sea salt to the pot. Cook, stirring occasionally, until the onion is soft and translucent, about 5 minutes.
While the vegetables are cooking, peel the potatoes, then chop into approx. ½" chunks.
Add the broth and scrape up any brown bits on the bottom of the pan. This will not only add flavor to the soup but it will make cleaning the pot later much easier.
Stir in the clam juice, almond milk, coconut milk, hot sauce, bay leaf, dried thyme, black pepper and reserved clam juice. Turn the heat up to high to bring the soup to a boil, then reduce the heat to medium so it simmers for about 15-20 minutes, until reduced and slightly thickened.
While the soup is simmering, peel the potatoes and cut into approx. ½" chunks. When the soup has simmered for 15-20 minutes, add the potatoes and simmer for another 10-12 minutes, or until the potatoes are soft and can be pierced with a knife or fork.
Turn off the heat. Remove and discard the bay leaf.If using a stick blender, blend the soup just until some of it is smooth but it still has a chunky texture.If using a regular blender, carefully ladle about half the soup into the blender jar. Cover with the lid, remove the lid's insert and hold a towel over the hole (this will help let the steam escape so the hot soup won't explode everywhere). Blend until smooth, then pour back into the pot. Turn the heat back on to medium. Stir in the drained clams and simmer for about 5 minutes. Taste and adjust seasonings. Serve topped with the bacon and parsley.
