Ingredients For Sausage & Sauerkraut
This simple recipe calls for only a few staple ingredients:
- Sausage: Use a cooked sausage such as smoked sausage or kielbasa, cut into 1-inch pieces.
- Sauerkraut: 28–32 ounces, including the juice (do not drain unless you prefer a milder flavor).
- Apple: One large apple, diced; Granny Smith works well for brightness.
- Onion: One small onion, diced.
- Dijon mustard: About 2 tablespoons; omit if you dislike mustard.
- Caraway or dill seeds: 2 teaspoons; fennel seed is an acceptable substitute.
- Salt & pepper: To taste.

How To Make Sausage And Sauerkraut In The Slow Cooker
This is a true set-it-and-forget-it slow cooker meal. Simply combine and cook:
- Add the sausage, sauerkraut (with its juice), diced apple, diced onion, Dijon mustard, caraway or dill seeds, and salt and pepper to the slow cooker. Stir to combine.
- Cook on HIGH for 2–3 hours or on LOW for 4–6 hours, until heated through and flavors meld.

What Type Of Sausage To Use
Use a pre-cooked sausage such as smoked kielbasa or another smoked link. Choose a brand you trust for flavor and ingredient quality. For Whole30 or other dietary plans, select a compliant sausage that fits your requirements.

Sauerkraut To Use
Whether to rinse sauerkraut is a matter of taste. Leaving the juice preserves the full tang and helps flavor the dish; rinsing will soften the strong flavor and reduce some sodium. Use about 28–32 ounces total — for example, two 14.5-ounce cans (approximately 29 ounces).

Adding Potatoes
If you want a heartier meal, add up to 1 pound of potatoes. Choose waxy varieties such as baby potatoes, red, or yellow potatoes so they hold their shape during the longer cooking time.

Storing Leftover Sausage & Sauerkraut
Store leftovers in an airtight container in the refrigerator for up to 5 days. For longer storage, place cooled leftovers in a freezer-safe bag or container and freeze for up to 4 months.
