Slice the onion and place in a 9 to 10 inch skillet.

Pour beer into the skillet with the onions.

Add bratwurst to the skillet.

Simmer the brats and onions until the onions are tender and the brats are firm and cooked through (160 F internal temp).

Allow beer to evaporate, while browning brats and onions.

Turn brats and onions frequently, adding a little oil if the pan needs it to prevent sticking.

Remove the onions when they turn golden brown.

Plate the browned brats.

Wrap the hot dog buns in paper towels and microwave on high for about 30 seconds until soft and warm.

Serve brats in buns with mustard, baked beans, and/or chips.
