How to Make Slow Cooker Bangers and Onions

1. Prepare the onions

Peel and slice the onions into thin rings or half-rings. Spread them evenly across the bottom of the slow cooker.

2. Add the sausages

Place the sausages on top of the onions. Keeping them whole helps retain their juices while cooking.

3. Add the liquid

Pour the beef broth over the sausages and onions. Then add the Worcestershire sauce to enhance the savory flavor.

4. Cook

Cover the slow cooker and cook:

• Low: 6–7 hours

• High: 3–4 hours

During cooking, the onions will soften and combine with the sausage juices to create a flavorful sauce.

5. Serve

Serve the sausages and onions hot with:

• Mashed potatoes

• Rice

• Crusty bread

The onion-rich sauce works perfectly as a topping.

Tips for the Best Flavor

Brown the sausages first (optional)
Lightly browning them in a pan before adding them to the slow cooker can deepen the flavor and improve texture.

Use sweet onions
Sweet onions caramelize better and add more natural sweetness to the dish.

Thicken the sauce
If you want thicker gravy, mix 1 tablespoon cornstarch with water and stir it in during the last 15 minutes of cooking.
