If you've been guilty of opening up a package of brats and immediately putting them on the grill, please stop. Stop and take about a half hour and let them take a dip on a simmering beer and onion bath and THEN put them on the grill to brown up and crisp. Trust me, it's an entirely different flavor and texture.
12 package of brats (I used Johnsonville brand)
2 - 16 oz. bottles of beer
2 medium yellow onions, thinly sliced
In a 5 - 6 quart Dutch oven, over low heat add beer and onions. Bring to a gentle simmer and then add brats. Let the bratwurst simmer for 20 - 30 minutes. Remove from heat and then place on the grill. Allow brats to brown and crisp. Place in buns and serve immediately with lots of mustard and kraut!
