Today we’re rustling up a bit of Polish sausage. This sausage dish has been cooked up… well, countless times in my house. It’s addictive stuff, and if you’re on board with meat and beer then you won’t look back. Here’s how to cook kielbasa.

See, the key to the most delicious sausage isn’t to grill or oven cook them, but to let them stew in sauces for hours to soak up as much flavor as possible. It sounds like a lot of work, but as long as you have time on your side then it couldn’t be simpler.

This recipe makes for a great party snack or starter. Disclaimer: I am a huge mustard fan. And any recipe that includes the yellow stuff has my instant attention. In fact, even if a recipe doesn’t feature mustard I’ll still my best to fit it in some way.

On top of that, the beer and brown sugar just sets the whole thing off. They’re definitely not two ingredients that I’d immediately think of when dreaming up a meat-based dish.

It couldn’t be easier to make, with it only taking a few minutes of prep before being thrown into the slow cooker for it to do its magic. Just like with any slow cooker recipe, the longer you leave it in the better it will taste. And this couldn’t be closer to the truth with it cooking in beer and mustard. It all comes together to form a beautifully sweet and caramelized flavor.

Side Dish Ideas

With its mustard and beer ingredients, this turkey kielbasa dish has a specific balance of flavors, but we have the some delicious side ideas. Here are a few of our favorite ideas of what to serve with kielbasa:

  • Sauerkraut: An Eastern European classic, sauerkraut is adds a crunch and level of tangy flavor that pairs beautifully with beer and yellow mustard. If you have time on your side, it’s easy to make this fermented cabbage dish. However, you’ll be forgiven for opting for store-bought.
  • Green Bean Casserole: A Midwest favorite, green bean casserole is made with crispy onions, cream of mushroom soup and – of course – green beans. You can have it as a simple side, or go one step further and add chopped kielbasa to the casserole dish.
  • Fried Onions: The sharp taste and crunchy texture of fried onions contrast nicely with sausage. Simply soak chopped onion in buttermilk for a few minutes before pan-frying them in paprika and cayenne pepper.
