Pour the chicken broth evenly over everything in the slow cooker. The liquid will not completely cover the ingredients; that’s fine. As the cabbage releases its juices, it will create plenty of savory broth.
Cover and cook on LOW for 6 to 8 hours, or on HIGH for 3 to 4 hours, until the potatoes are very tender and the cabbage is soft and translucent. The sausage should be heated through and lightly browned around some of the edges.
Once cooked, gently stir from the bottom to mix the sausage, cabbage, and potatoes together without mashing the potatoes too much. Taste and, if you like, add a pinch of salt and black pepper at the table.
Ladle the sausage, cabbage, and potatoes into bowls, making sure each serving gets some of the flavorful broth from the bottom of the slow cooker. Serve hot.
Variations & Tips
This four-ingredient version is meant to be as simple and budget-friendly as my uncle always made it, but you can nudge it a little this way or that. If you have time in the morning, you can brown the sliced sausage in a skillet first to deepen the flavor and give it a bit more color before adding it to the slow cooker. For a slightly sweeter, more old-fashioned farmhouse taste, stir in a thinly sliced onion with the cabbage, or add a chopped apple on top of the potatoes—just know that will take you beyond the strict four-ingredient idea. You can also swap the chicken broth for beef broth for a heartier flavor, or use water and a bouillon cube if that’s what you have on hand. If you prefer, use red potatoes instead of yellow; they hold their shape nicely. Leftovers reheat well in a saucepan over low heat, and if the broth has thickened, just splash in a little extra water or broth to loosen it. A dash of cider vinegar or a spoonful of grainy mustard at the table is a very Midwestern way to brighten the bowl without changing the basic recipe
