In a medium skillet over medium heat, cook bacon until just crisp. Remove with a slotted spoon to a paper-towel-lined plate and set aside.
Melt 2 tablespoons of butter in a large Dutch oven or saucepan. Add onion and sauté for 5-7 minutes until softened. Add the garlic, fresh thyme, dried parsley and
cayenne, stirring for 1-2 minutes until the garlic is fragrant. Sprinkle in flour and stir for 1-2 minutes until it’s incorporated and golden.
Add potatoes, vegetable stock, 1 cup of clam juice, milk and bay leaves. Bring to a simmer and cook for 15-20 minutes or until the broth is reduced and the potatoes are fork tender.
Remove bay leaves and stir in light cream, chopped clams and rest of clam juice. Simmer for 5-10 minutes until warmed through.
Season the chowder with salt and pepper, then add bacon, reserving some for topping.
Meanwhile, spread some of the Treasure Cave Gorgonzola cheese wedge onto 2 pieces of sourdough bread. Top each piece with the other piece of bread. Melt the remaining 2 tablespoons of butter in a large skillet and cook the grilled cheeses on each side until golden. Remove to a cutting board and slice each into small square croutons.
Serve chowder topped with reserved bacon, chopped parsley, additional black pepper, Gorgonzola grilled cheese croutons, and Treasure Cave Crumbled Gorgonzola Cheese.
