Preheat oven to 425F.
In a large saucepan, combine beef broth, sliced sausages, and bacon; bring to a boil.
Reduce heat to low and simmer for 10 minutes.
Transfer sausages and bacon to a bowl and reserve the broth.
Lightly grease a dutch oven or casserole dish with cooking spray.
Spread one-third of the potatoes on the bottom of the casserole dish.
Arrange 1/3 of the onions and carrots over the potatoes, and season with a little salt and pepper.
Spread a layer of the previously prepared sausages and bacon over the layer of onions.
Continue to layer ingredients two more times, seasoning with salt and pepper as you go along.
Pour the reserved broth over the entire dish.
Cover with a lid and bake in the oven for 40 minutes.
Remove cover and if mixture looks dry, add 1/2-cup water. Continue to bake for 15 minutes, or until lightly browned on top.
Remove from oven and let stand 5 minutes.
Ladle into bowls and garnish with fresh parsley.
