Wash your potatoes thoroughly under cold water. Peel or leave the skin on as preferred, then cut into halves or quarters.

Place the prepared potatoes evenly in the bottom of the slow cooker.

Sprinkle the Lipton onion soup mix generously over the layer of potatoes.

Pour the beef or chicken broth over the potatoes to ensure they are well-coated.

Dot the top of the potatoes with small pieces of butter.

Season with salt and pepper, cover, and cook on low for 6-8 hours or high for 3-4 hours.

Check for doneness; potatoes should be fork-tender. Cook longer if necessary.

Serve warm and garnish with freshly chopped parsley if desired.
