Slow Cooker Bangers and Onions
A Cozy British-Inspired Comfort Dish
Bangers and Onions is a rustic, comforting meal inspired by the traditional British favorite often served in pubs and family kitchens. In this slow cooker version, juicy pork sausages simmer slowly with sweet onions in a rich, savory gravy made from beef broth and Worcestershire sauce.
The slow cooking process allows the onions to melt down into the sauce, creating a deep, caramelized flavor that perfectly coats the sausages. Best of all, this recipe uses just four simple ingredients and requires almost no hands-on cooking.
Serve it over creamy mashed potatoes, buttered egg noodles, or with crusty bread to soak up every drop of the rich gravy.

Ingredients (Serves 4–6)

2 tablespoons Worcestershire sauce

Pro Tips Before You Start
✔ Choose thick sausages rather than thin breakfast links—they hold their shape better during slow cooking.
✔ Slice onions evenly so they cook down into a smooth gravy.
✔ Avoid stirring once sausages are added so they stay intact while cooking.
Step-by-Step Instructions
1. Layer the Onions
Place the thinly sliced onions in the bottom of a 6-quart slow cooker, spreading them into an even layer.
The onions will soften and slowly turn into a flavorful base for the gravy.
2. Add the Sausages
Lay the pork sausages on top of the onions.
Arrange them in a single layer if possible.
There’s no need to brown them first—the slow cooker will cook them perfectly.
3. Pour the Liquid
Pour the beef broth and Worcestershire sauce around the sausages and onions.
Try not to pour directly on top of the sausages so the layers stay intact.
4. Slow Cook
Cover with the lid and cook:
LOW: 6–7 hours
or
HIGH: 3–4 hours
The sausages will become juicy and tender while the onions soften into a rich gravy.
5. Serve
Once cooked, gently remove the sausages and spoon the onion gravy over them.
Serve hot with your favorite side.
