Few meals feel as hearty and comforting as a plate of sausages served with creamy mashed potatoes and rich onion gravy. It’s a timeless combination that has stood the test of time across cultures, often known in Britain as bangers and mash. This dish is simple, affordable, and deeply satisfying, making it perfect for family dinners, casual gatherings, or even a cozy solo meal on a cold evening.
The recipe is straightforward: sausages are pan-fried until golden brown, potatoes are mashed to smooth perfection with butter and milk, and onions are slowly caramelized into a flavorful sauce thickened with broth. The result is a dish that strikes the perfect balance of richness, creaminess, and savoriness.
Why This Dish Is a Classic
The pairing of sausages and mashed potatoes goes back centuries. It became popular in the UK during the early 20th century, when sausages often contained fillers that caused them to pop or “bang” when cooked, hence the name bangers. Paired with mashed potatoes, which were inexpensive and filling, the dish quickly became a working-class favorite.
Over time, it evolved into a beloved comfort food served not only at home but also in pubs and restaurants. Today, it’s enjoyed worldwide, with regional variations ranging from German bratwurst to Italian-style sausages. The essence, however, remains the same: hearty sausages paired with creamy mash and a rich sauce.
Ingredients
To prepare sausages with mashed potatoes and onion gravy, you’ll need:
For the Sausages
- 6 beef or chicken sausages (or your favorite type)
For the Mashed Potatoes
- 1 kg potatoes, peeled and cut into chunks
- 3 tablespoons butter
- ½ cup warm milk
- Salt and pepper, to taste
For the Onion Sauce
- 2 medium onions, thinly sliced
- 2 tablespoons butter
- 2 tablespoons flour
- 2 cups beef or chicken broth
- A little fresh herbs (parsley or thyme, optional)
- Salt and pepper, to taste
Step-by-Step Instructions
Preparing the Mashed Potatoes
- Peel the potatoes and cut them into medium chunks to ensure they cook evenly.
- Place them in a pot of salted water and bring to a boil. Cook until tender, about 15–20 minutes.
- Drain the potatoes well, then return them to the pot. Add the butter and warm milk.
- Mash until smooth and creamy, seasoning with salt and pepper to taste. Keep warm until serving.
Cooking the Sausages
- Heat a skillet or frying pan over medium heat.
- Place the sausages in the pan and cook slowly, turning often, until browned on all sides and cooked through (about 12–15 minutes depending on thickness).
- Remove from the pan and keep warm while preparing the sauce.
Making the Onion Sauce
- In the same pan, melt the butter and add the sliced onions.
- Cook over medium-low heat until the onions soften and begin to caramelize, about 8–10 minutes.
- Sprinkle in the flour and stir well to coat the onions.
- Gradually add the broth, stirring constantly to prevent lumps.
- Simmer until the sauce thickens to a gravy-like consistency. Add herbs if desired, and season with salt and pepper.
Assembling the Dish
- Place a generous serving of mashed potatoes on each plate.
- Arrange the sausages on top.
- Spoon the onion sauce generously over the sausages and potatoes.
- Garnish with fresh herbs if you like, and serve hot.
Serving Suggestions
This dish is versatile and can be paired with many side options to make it even more filling and well-rounded.
- Green vegetables: Serve with steamed peas, green beans, or broccoli to balance the richness.
- Pickled sides: Add tangy pickles or sauerkraut to cut through the creamy mash.
- Bread on the side: A slice of crusty bread is perfect for soaking up leftover sauce.
- Wine or beer: Pair with a glass of red wine, dark ale, or even cider for a true pub-style experience.
Tips for the Best Sausages with Mashed Potatoes
- Choose quality sausages: The flavor of the dish depends heavily on the sausages. Opt for butcher-made or high-quality ones with natural casings.
- Warm the milk for mash: Adding cold milk can cause the potatoes to seize and become gluey. Always warm it first for a creamy texture.
- Caramelize onions slowly: Don’t rush this step—the deeper the color, the richer the flavor of your gravy.
- Make it ahead: The onion sauce and mashed potatoes can be prepared in advance and gently reheated before serving.
- Double the sauce: If you love extra gravy, double the recipe so everyone can pour more over their mash.
Variations to Try
- Cheesy Mash: Stir grated cheddar or parmesan into the potatoes for added flavor.
- Spicy Sausages: Use chorizo or another spicy sausage for a bold twist.
- Vegetarian Option: Use plant-based sausages and vegetable broth for a meat-free version.
- Mustard Gravy: Add a teaspoon of Dijon mustard to the sauce for a tangy punch.
- Herbed Mash: Infuse the milk with garlic or rosemary before mixing it into the potatoes.
FAQs
Can I use instant mashed potatoes instead of fresh?
Yes, but fresh potatoes yield a much creamier, more authentic texture. Instant mash can work in a pinch, but the flavor won’t be as rich.
What’s the best type of potato for mash?
Starchy potatoes like Russets or Yukon Golds are ideal. They mash smoothly and create a fluffy texture.
Can I bake the sausages instead of frying?
Absolutely. Place them on a baking tray and roast at 190°C (375°F) for 25–30 minutes, turning halfway through, until cooked and golden.
How do I make the sauce gluten-free?
Replace the flour with cornstarch or gluten-free flour. Whisk it with a little cold broth before adding to the pan to prevent lumps.
How long does this dish keep?
Leftovers can be stored in an airtight container in the fridge for up to 3 days. Reheat the mash with a splash of milk and the sauce over low heat.
Can I freeze mashed potatoes and gravy?
Yes, both freeze well. Freeze them separately in airtight containers for up to 2 months. Thaw overnight in the fridge before reheating.
