Melt butter in skillet, add brats and sear both sides over medium heat, turning to brown both sides – a total of about 5 minutes.
Add sliced onions, toss brats and onions and cook over medium heat for 2 minutes, turning often. Turn heat to low and add ½ cup water, cover and let simmer for 12 minutes or until internal temperature of brats reach 160 degrees.

Notes
You CAN do without the water if desired, but the water helps “steam” and allow the brats to cook through.
