Before you start
Before beginning, ensure that your work area is clean and that you have all your ingredients measured and ready. Slice your bell peppers and onions into uniform strips to ensure consistent cooking.
It is recommended to keep the bratwurst refrigerated until the very last moment before you place them into the slow cooker to maintain food safety standards. Having your ingredients prepared in advance allows for a seamless assembly process.

Instructions
Assembly of ingredients
- Prepare the slow cookerPlace the raw bratwurst links in the bottom of the slow cooker. Scatter the sliced bell peppers and onions evenly over the sausages to ensure they cook thoroughly in the liquid.Look for Ensure the sausages are arranged in a single layer at the bottom of the cooker.Tip Slicing the peppers and onions into uniform strips helps them cook evenly alongside the meat.
At this stage, the slow cooker should be neatly arranged with the raw sausages at the base and the colorful peppers and onions layered on top. Everything is cold and raw, waiting for the cooking process to begin. Ensure the power cord is clear of any water sources, and confirm that the ingredients are distributed evenly so that the heat will penetrate the mixture uniformly once the slow cooker is activated.
Adding the beer and mustard
- Add aromatics and liquidAdd the spoonful of brown mustard over the sausage and vegetable mixture. Pour the lager beer carefully into the slow cooker until the ingredients are partially submerged.Look for The beer should create a shallow pool that surrounds the sausages without completely covering them.Tip Pouring the beer slowly prevents the mustard from washing away immediately.
Once the mustard and beer are added, the slow cooker will contain a fragrant, shallow liquid base. The mustard should be slightly dispersed among the vegetables. The atmosphere should be clean and organized. Check that the beer level is sufficient to keep the sausages moist without drowning them, and ensure that the lid is positioned securely to trap the heat and steam effectively for the duration of the cooking cycle.
Cooking to completion
- Cook and serveCover and cook on low for 4 hours until the sausages reach an internal temperature of 160°F (71°C). Remove the sausages and vegetables, let rest for 5 minutes, then serve.Look for The sausages will be plump and firm, and the peppers will be soft and translucent.Safe temperature 160°F (71°C) internal temperature (ground meat)Tip Use a meat thermometer to ensure the sausages have reached the safe temperature of 160°F (71°C).
After four hours, the kitchen will be filled with the savory aroma of beer-braised sausage and sweet onions. The sausages should feel firm to the touch and be thoroughly cooked through.
The peppers should be soft and wilted, having integrated with the beer sauce. Verify the internal temperature with a thermometer before removing the lid permanently to serve, ensuring the food has reached the required safety standards for consumption.
Common mistakes
A common mistake is overcrowding the slow cooker or using too much liquid, which can result in the sausages boiling rather than gently poaching in the beer. Another error is checking the cooker too frequently; every time the lid is lifted, heat escapes, extending the cooking time unnecessarily.
Always keep the lid closed as much as possible. Finally, ensure the sausages are not cooked at too high a heat, as this can cause the casings to burst prematurely.
How to tell it’s done
The bratwurst is done when the internal temperature reaches 160°F (71°C) as measured by a food thermometer. The sausages should appear plump and have a slightly darkened, firm exterior.
The peppers and onions should be very tender and have absorbed the beer and mustard flavors. Always allow the cooked sausages to rest on a plate for at least 5 minutes before serving to ensure the juices redistribute throughout the meat, providing the best possible texture.
- Ground meat: 160°F (71°C) in the thickest part
