There is nothing that signals a backyard cookout in the Midwest quite like beer boiled brats sizzling on the grill. These sausages are slowly simmered with onions and lager before getting just the right amount of char over an open flame. This recipe guarantees juicy brats filled with flavor and makes for an easy main dish with a true Midwestern touch.
The moment I learned to simmer the sausages in beer and onions was a total game changer. Friends still ask for these at every summer get together and not a single brat is ever left.

Recipe FAQs
- → What type of beer is best for boiling bratwursts?
A light lager, such as Miller High Life, works well to tenderize the sausages and impart subtle malt flavors without overpowering them. Avoid using heavily hopped or dark beers, as these can leave bitter notes.
- → How do I prevent bratwursts from splitting during cooking?
Simmer the brats gently in the beer and avoid high, direct heat at first. Don’t prick the sausages—this keeps the juices inside and preserves their texture.
- → Should the onions be served with the bratwursts?
Absolutely! The onions from the beer bath soak up incredible flavor and make the perfect sweet-savory topping for each bratwurst in its bun.
- → What’s the best way to serve beer-boiled brats?
Pile the bratwursts into toasted hot dog buns, then add onions, spicy mustard, pickles, and sauerkraut. These classic toppings enhance both texture and flavor.
- → Why finish the brats on the grill after boiling?
Grilling after boiling gives the sausages a smoky, charred exterior while keeping the inside juicy. It also intensifies the overall flavor and texture.
