Want to take the labor out of cooking on Labor Day? Then these beer brats are for you. They will start cooking before your guests arrive.

Once they are cooked you can turn the slow cooker down to low and they can bathe in the hot tub until everyone is ready to eat. Just set out the buns and condiments, then you can sit back and relax.

Oktoberfest Bratwurst

These brats are not just great for Labor Day and game day and tailgating, Oktoberfest is also a great time to enjoy these as they are German after all.

I could live on sausages. I love all types from hot dogs to brats and of course, British bangers. I recently added another recipe that is perfect for Oktoberfest, German Beer Sausage and Potatoes. The most delicious comfort food.

My love of brats with sausage and peppers came about many years ago when I first starting dating my husband. Every year we would attend the Long Beach Grand Prix and see the Indy cars race.

When we arrived at the track, the first thing we did was get brats and beer, which was usually breakfast. Before I came along, my now husband used to go to the race with his friend Brad, who then named the brats ‘dag nasties’. That name has stuck and we call them that to this day.

This recipe is for 4 people, but it’s easy to double or triple the recipe. Just make sure you have a slow cooker big enough, or borrow a second one for the day.

Bratwurst in the slow cooker tip

When you add all the ingredients to the slow cooker, it will look like there are too many onions and peppers, but they do cook down a lot.

I bought my bratwurst from a local German market and there were a lot to choose from, but you can buy any bratwurst that your local supermarket carries.

Bratwurst serving suggestion

If you want to make these really German, add store bought sauerkraut.
