In a dutch oven, over medium-high heat, cook the chopped bacon until crisp, about 5 minutes. Remove the bacon from the pan, leaving the rendered fat behind.
Add the sausages and brown on all sides, about 2 minutes per side. Remove the sausages from the pan. Discard excess fat from the pot, leaving 2 tablespoons behind.
Add the sliced onions and leeks. Cook until soft and tender, about 5 minutes. Add the garlic and cook until fragrant, about 1 minute.
Add the potatoes, parsley, salt, and pepper. Stir to combine. Pour the broth over top. Bring to a simmer.
Turn off the heat. Nestle the sausages into the potatoes and sprinkle the bacon over top.
Cover and cook in the oven for 2 hours. After 2 hours, remove the lid and cook uncovered for another 45-60 minutes.
