Cook bacon in a large Dutch oven or pot over medium heat. Remove with slotted spoon and let drain on a paper towel lined plate.
Turn heat up to med-high, add sausage, and brown while braking up (about 5 minutes). Remove with slotted spoon onto another paper towel lined plate. Remove excess oil from pot, leaving ~2 tablespoons in the bottom.
Reduce heat to medium, add onions and let them sweat until tender (about 10 minutes). Add the garlic and cook another 30-60 seconds.
Add the potatoes, water, bouillon, and parmesan rind (optional) to the pot and bring to a boil over high heat. Reduce to medium heat and simmer for about 7-8 minutes or until potatoes are fork tender.
Stir in the kale, cream, and browned sausage. Simmer for 2-3 minutes or until kale is wilted.
Season with salt and pepper to taste and serve garnished with bacon and parmesan.
