Most of my family lives in Wisconsin. Besides the Packers, Wisconsin is known for their beer, brats, and cheese.
In this slow cooker beer brats recipe, I am going to teach you the tricks I have learned on how to cook the most delicious crockpot beer brats and onions you will ever make!

The people who live in Wisconsin have their own tricks to making the perfect brats.
Some people cook them in beer and onions before grilling them and others grill the brats first.
I prefer grilling my brats first to lock in the crispy skin.

Tips for the perfect Brats
Cooking your brats long and slow in the beer sauce allows the brats and onions absorb that amazing beer flavor.
Tip: This is an opportunity to cook with a really good flavored beer. Some people use a cheap light beer, but the brats can handle a flavorful beer.
I like to use a locally brewed hoppy craft beer from Dirtbag Ales. Dirtbag Ales is a great little brewery located in Hope Mills, NC.
If you have the opportunity to visit the place; the beer is good and the atmosphere is fun.
Tip: If you do not want to use a grill, you can crisp the outer skin of the brats on a cast iron pan or skillet. Cook 3 minutes on each side.
