Keep in mind that there are many ways to cook beer brats.
This is my slow cooking method, and if you ask me, no other method makes them this tasty and tender. This whole process can take a whole day to prepare... so set a day aside, and get yourself a case of beer... Half for the Brats, and half for you!
Also, Never buy the beer Brats pre-made from the store, as they are not anywhere close to what a beer brat should taste like.
Step 1: Ingredients You'll Need
4 Packs of regular Brats (no cheese brats... they would not make it!)
4-6 Small - Medium Onions. I used Red and Yellow Onions
3-5 Cloves of Garlic.
1 Case of beer... does not need to be anything exotic.
1 day to babysit the beer brats while they cook.
Step 2: Poke the Brats.
Grab a fork, and poke some holes in the Brats... about 3-4 jabs aught to do good, but be careful, the brats need to be handled with care, as the slightest extra tear in the brat casing can make it rip apart.
Step 3: Add the Beer!
Start off by putting a few cans of beer into a large stock pot... or similar cookware.
Start the stove up, and get that beer bubbling, but careful! Beer will bubble over very easily! So not too hot... that's the key to this whole thing... Not too hot! Just hot enough to see some bubbling.
Step 4: Add Brats!
Step 5: Add Onions and Garlic!
Same for the Cloves of Garlic I used Some Red onion, and White onion.
Step 6: Top It Off!
Step 7: Simmer!
Be attentive to these things... when cooking so many it's easy to burn the ones on the bottom, but it's not easy to stir them around either.
Step 8: The Brats Are Ready!
I usually pack a few away in the fridge. If you do this, it gives you a chance to scoop up the hardened brat grease that will rise to the top and harden.
From here... All you need to do is to Grill it for a minute or so, to sear the outside of the brat. I used a George Forman Grill. While Grilling, pour some of the Beer/Onion sauce onto the brat.
Handle the Brats carefully! They break real easy!
