This comes from the Brown Eyed Baker. If you're looking for an easy method for how to cook kielbasa, this slow cooker recipe for Beer and Brown Sugar Polish Sausage with Sauerkraut is a super simple option! The recipe calls for pre-made sausage. You cook it to tender, juicy perfection in your slow cooker using beef, brown sugar, and sauerkraut. When the sausage and sauerkraut is done, serve it over your favorite sandwich roll with any sides of your choosing.
1Combine the beer and brown sugar in a small saucepan over medium heat, until the sugar melts and the mixture is slightly thickened. Set aside. Cut the kielbasa into links and place in a slow cooker. Cover with the drained sauerkraut.
2Pour the beer and brown sugar mixture over top. Cook on high for 4 to 6 hours, or on low for 8 to 10 hours. (We ended up doing a combination - high for 3 hours and then low for another 3 or so. Definitely the longer it cooks the better it tastes!) Serve on its own or on your favorite sandwich roll.
