Things You'll Need
2 cans of beer
1/4 cup butter
1 thinly sliced onion
Fire up the grill and get the brats ready. For many people, nothing says summer more than plump brats cooked to perfection on a backyard grill.
After you cook the brats carefully over a controlled flame, keep them warm until you are ready to serve them. One of the tastiest ways to keep brats warm is to submerge them in a simmering beer mixture (called a "batter") after you remove them from the grill. The beer batter not only keeps them warm, it also flavors them deliciously.
Pour the two beers into the crockpot. Add the butter and onion and stir the ingredients.
Set the crockpot to "low" and heat the beer batter to a simmer to melt the butter and soften the onions. Stir the batter again after it begins to simmer.
Place grilled brats into the simmering beer batter to keep them warm. Try to immerse the brats at least halfway into the batter for optimal heating and flavor.
Watch the level of the batter; add another beer if it cooks down.
Use a quick-read thermometer to make sure the temperature of the beer batter stays above 140 degrees (Fahrenheit).
To prevent dangerous bacteria from growing, keep the brats warmer than 140 degrees F. According to the USDA, bacteria multiply quickly on foods at temperatures between 40 and 140 degrees. Keep your brats out of this food “danger zone” before you serve them.
