Layer the potatoes: Place the sliced red potatoes in an even layer in the bottom of a 4- to 6-quart slow cooker, matching the image of raw sliced potatoes resting in the crock. If the slices are very tightly packed, gently toss them with your hands so the vinegar mixture can seep between layers, but keep them mostly in a single, shingled layer on the bottom.

Combine in the slow cooker: Pour the warm bacon-vinegar mixture evenly over the potatoes, making sure to drizzle across the entire surface so it can work its way down. Scatter the cooked bacon pieces over the top. Do not stir aggressively; you want the slices to hold their shape as they cook.
Slow cook: Cover and cook on LOW for 4–5 hours, or on HIGH for 2–3 hours, until the potatoes are tender when pierced with a fork but not falling apart. About halfway through the cooking time, gently lift the lid and use a wide spatula or spoon to carefully lift and turn the potatoes from the bottom once, just to help coat them in the dressing. Replace the lid quickly to retain heat.

Season and serve: When the potatoes are tender, taste a slice and add salt and black pepper if desired, tossing gently to avoid breaking the potatoes too much. Serve the German potato salad warm straight from the slow cooker, or transfer to a serving dish, spooning the tangy bacon dressing from the bottom over the top so every bite is well coated.
Variations & Tips
To keep this true to the “dump sliced red potatoes in the slow cooker and 3 other ingredients” promise, the core recipe relies only on potatoes, bacon, vinegar, and sugar; salt and pepper are listed as optional finishing seasonings so you can adjust to taste at the end.
If you’d like to dress it up while staying close to a traditional German profile, stir in 2–3 tablespoons of finely minced red or yellow onion and 1–2 tablespoons of whole-grain mustard with the vinegar and sugar before pouring over the potatoes. A small handful of chopped fresh parsley or chives added just before serving brings color and a fresh note.

For a slightly lighter version, you can reduce the bacon to 4–6 ounces and supplement with 1–2 tablespoons of a neutral oil (like canola) in the dressing. If you prefer a sweeter salad, add an extra teaspoon or two of sugar; for more tang, add up to 2 additional tablespoons of vinegar at the end, tasting as you go.
Food safety tips: Always cook bacon until it is fully crisp and the fat is rendered; undercooked bacon can harbor harmful bacteria. When adding vinegar to hot bacon fat, stand back and pour slowly to avoid sputtering. Keep the slow cooker covered as much as possible so it maintains a safe temperature; frequent lifting of the lid can extend cooking time and keep the food in the temperature “danger zone” (40–140°F) longer than necessary.

Once the salad is cooked, do not leave it at room temperature for more than 2 hours (or 1 hour if your kitchen is very warm). Refrigerate leftovers promptly in shallow containers and use within 3–4 days, reheating thoroughly until steaming before serving.
