Irish sausage
Onion gravy
Bangers and mash
Ingredients (serves 4)
For the sausages and gravy
- 8–10 Irish sausages
- 2 large onions, thinly sliced
- 2–3 cloves garlic, minced
- 2 tablespoons butter or oil
- 1 tablespoon flour (for thickening)
- 2 cups beef or chicken stock
- 1 teaspoon Worcestershire sauce
- 1 teaspoon mustard (optional, adds depth)
- Salt and black pepper to taste
- Fresh thyme (optional)
For serving
- Mashed potatoes (classic pairing)
Step-by-step instructions
1. Brown the sausages (recommended step)
- Heat a pan and lightly brown the sausages for 3–5 minutes
- This adds flavor but can be skipped if short on time
2. Prepare the onion base
- In the same pan, melt butter
- Add sliced onions and cook until soft and golden (8–10 minutes)
- Add garlic and cook for 1 minute
- Stir in flour and mix well
3. Build the gravy
- Slowly add stock while stirring to avoid lumps
- Add Worcestershire sauce, mustard, salt, and pepper
- Simmer for 2–3 minutes until slightly thickened
4. Slow cook
- Place sausages in the slow cooker
- Pour onion gravy over them
- Add thyme if using
- Cook on:
- LOW: 6–7 hours
- HIGH: 3–4 hours
The sausages will become tender and absorb the gravy flavor.
5. Final thickening (if needed)
- If gravy is thin, remove lid for last 20–30 minutes
- Or stir in a small cornstarch slurry
Serving suggestion
- Serve hot sausages over mashed potatoes
- Spoon generous onion gravy on top
- Optional sides:
- peas
- steamed carrots
- crusty bread
Tips for best results
- Browning sausages improves flavor significantly
- Slow cooking on low heat gives the best texture
- Use good-quality pork sausages for authentic taste
- Gravy thickens more as it cools slightly

This slow cooker version of bangers and mash is simple, hearty, and ideal for a hands-off meal. The long cooking time allows the sausages to stay juicy while the onion gravy becomes rich and flavorful.
