Expert Tips
Sauerkraut - We recommend draining the sauerkraut because of how tart the Sauerkraut is. To make it even less tart, rinse the sauerkraut before adding it in the slow cooker.
Onion and Garlic - We make things easy but just tossing the garlic and onion in the slow cooker, but if you prefer you can sauté them before adding.
Kielbasa - The kielbasa we used is the smoked kielbasa. You can also use bacon or other types of pork.
Seasoning - We used simple seasoning, but they can be changed to what you have hand.
