Ingredients
To make this easy slow cooker sausage and onion recipe, you’ll need:
- 2 pounds sausages (bangers or your favorite sausages) – about 8 links
- 3 large yellow onions, thinly sliced
- 2 cups beef stock (preferably low sodium)
- 2 tablespoons Worcestershire sauce
How to Make Slow Cooker Bangers and Onions
1. Slice the Onions
Peel and thinly slice the onions. Thin slices cook evenly and turn soft and sweet during slow cooking.
2. Brown the Sausages (Optional)
Heat a skillet over medium-high heat and sear the sausages for 2–3 minutes per side until lightly browned. This adds deeper flavor to the finished dish.
If you prefer, you can place the sausages directly in the slow cooker.
3. Layer the Onions
Spread the sliced onions evenly on the bottom of a 4–6 quart slow cooker.
4. Add the Sausages
Place the sausages on top of the onions in a single layer.
5. Prepare the Gravy
In a bowl, mix together:
- Beef stock
- Worcestershire sauce
Pour the mixture evenly over the sausages and onions.
6. Slow Cook
Cover and cook:
- LOW for 6–8 hours, or
- HIGH for 3–4 hours
The onions will soften and the liquid will transform into a rich onion gravy.
7. Thicken the Gravy (Optional)
For thicker gravy:
- Remove the lid during the last 30 minutes, or
- Mash a spoonful of cooked onions and stir them back into the sauce.
8. Serve
Serve the tender sausages with onions and gravy hot over mashed potatoes or with your favorite sides.
Optional garnish: chopped fresh parsley.
