If you're following a low carb or keto diet like many of our readers, you might be wondering which of our bratwurst recipes are keto! ANY of these are keto bratwurst recipes as long as you skip the bun, and use a low carb beer like Michelob Light. Be sure to keep the carbs down as low as possible when eating keto brats, by making sure to buy sauerkraut that doesn't add extra sugar, or you can even cut back on the sauerkraut all together. Some brands of brats have a tiny bit of sweetener added, that's probably what's giving 1-2 net carbs in each serving.
