Origin

Bratwurst is a traditional German sausage, with its name derived from German words associated with finely chopped meat and sausage. While bratwurst has deep roots in Germany, beer brats became especially popular in German-American communities, particularly in the Midwest of the United States. Cooking bratwurst with beer and onions combines German sausage traditions with American comfort-food techniques.

Tips for Success

---

Choose a flavorful beer: A lager or pilsner works particularly well because it adds flavor without overpowering the sausage.
Don’t overcrowd the slow cooker: Arrange the brats so the cooking liquid can circulate around them.
Use plenty of onions: They become soft, sweet, and deeply flavorful during slow cooking.
Avoid excessive cooking: Bratwurst can become less juicy if left cooking far beyond the recommended time.
Toast the buns: Lightly toasted buns provide a pleasant contrast to the tender sausage and onions.
Brown for extra flavor: For a more traditional grilled taste, quickly brown the cooked brats in a skillet or on a grill before serving.
Check doneness: Use a food thermometer and cook the bratwurst to a safe internal temperature appropriate for the sausage.
