Anna Louise A one pot sausage casserole is the weeknight dinner that asks almost nothing of you and gives back an enormous amount.
Good sausages browned until golden, vegetables softened in the same pan, everything simmered together in a rich tomato and stock sauce until the sausages are cooked through and the sauce has become something deeply flavoured and completely satisfying.
Mary Berry’s one pot sausage casserole recipe is the version that works without drama — brown the sausages, soften the vegetables, add the liquid, simmer until done. The whole thing is in one pan and takes under an hour.
The result is the kind of dinner that earns a specific place in the weekly rotation — the meal that everyone at the table looks forward to without quite being able to explain why.
It is because it is done properly. And done properly, a sausage casserole is genuinely wonderful.
The Key to a Great Sausage Casserole
Good sausages. The sausage is the primary ingredient and its quality determines the quality of the finished dish. A high-meat-content pork sausage — Cumberland, Lincolnshire, or from your local butcher — gives a completely different result from a cheap supermarket sausage. Use the best you can find. The difference is immediately and completely apparent.
Properly browned sausages. The sausages must be browned before the liquid goes in — properly browned, not just grey and cooked. The Maillard reaction on the surface of the sausage gives a colour and a flavour that cannot develop in a liquid environment. Brown in batches in a hot pan.
A rich, well-seasoned tomato and stock sauce. The sauce needs depth — tomato purée for concentration, smoked paprika for warmth, Worcestershire sauce for umami. All three together give a sauce that is far more interesting than tomatoes and stock alone.
Ingredients for Mary Berry One Pot Sausage Casserole
- 8 good quality pork sausages
- 2 tbsp sunflower oil
- 1 large onion, roughly chopped
- 2 red peppers, deseeded and roughly chopped
- 3 garlic cloves, crushed
- 1 tsp smoked paprika
- 1 tsp dried thyme or 1 tsp fresh thyme leaves
- 2 tbsp tomato purée
- 400g tin chopped tomatoes
- 300ml good quality chicken or beef stock
- 1 tbsp Worcestershire sauce
- 1 tsp caster sugar
- 400g tin cannellini beans or butter beans, drained and rinsed (optional — adds substance)
- Salt and freshly ground black pepper
- Fresh flat-leaf parsley, chopped, to finish
How to Make Mary Berry One Pot Sausage Casserole — Step by Step
Step 1 — Brown the Sausages
Heat the sunflower oil in a large, deep frying pan or casserole over a medium-high heat. Add the sausages and cook for eight to ten minutes, turning regularly, until deeply browned all over. They do not need to be fully cooked through at this stage — they will finish cooking in the sauce.
Remove the sausages and set aside. If they are very large, cut each one in half on the diagonal — this looks attractive and means more surface area absorbs the sauce during cooking.
Step 2 — Soften the Vegetables
In the same pan, reduce the heat to medium. Add the onion and red peppers. Cook for eight minutes, stirring occasionally, until softened and beginning to colour. Add the garlic, smoked paprika, and thyme. Cook for two more minutes until fragrant.
Step 3 — Build the Sauce
Add the tomato purée and cook for one minute. Add the chopped tomatoes, stock, Worcestershire sauce, and sugar. Season generously with salt and pepper. Stir well, scraping up any browned bits from the base of the pan.
Step 4 — Return the Sausages and Simmer
Return the sausages to the pan, nestling them into the sauce. Bring to a gentle simmer. Cook uncovered over a low to medium heat for 25 to 30 minutes, stirring occasionally, until the sauce has reduced and thickened significantly and the sausages are cooked through.
If using beans, add them in the final ten minutes of cooking — stir through gently and warm through.
Step 5 — Finish and Serve
Taste and adjust the seasoning. Scatter generously with fresh parsley. Serve directly from the pan.
My Top Tips For Mary Berry One Pot Sausage Casserole
Brown the sausages properly. Eight to ten minutes in a hot pan until deeply, evenly golden all over. This is the step that makes the most difference to the flavour of the finished casserole. Do not rush it and do not crowd the pan.
Add beans for extra substance. A tin of cannellini or butter beans added in the final ten minutes gives the casserole an extra protein and fibre hit, thickens the sauce slightly, and makes it more filling. It is one of the most useful additions to a simple sausage casserole.
Smoked paprika is the spice that ties everything together. Just one teaspoon of smoked paprika gives the sauce a depth and warmth that makes it taste far more complex than the ingredient list suggests. Do not substitute sweet paprika.
Cook uncovered for the final 20 to 25 minutes. The uncovered simmering reduces the sauce and concentrates the flavours. A lid on throughout gives a thinner, more watery sauce with less depth.
Use the same pan throughout. The browned bits left in the pan after cooking the sausages contain concentrated flavour — deglaze them into the sauce. A one-pot dish that uses one pan from start to finish also means far less washing up.
Serving Suggestions
With creamy mashed potato — the rich sauce and soft mash is perfect. With crusty bread for mopping. With steamed green beans or tenderstem broccoli for freshness. Over polenta for something more Italian in character.

Notes
Frequently Asked Questions
Can I use different types of sausage?
Yes — Italian sausages with fennel work beautifully and give a Mediterranean character. Chorizo added alongside pork sausages gives a smoky depth. Chicken sausages give a lighter result. The method is the same for all.
Can I make this in a slow cooker?
Yes — brown the sausages and soften the vegetables as directed, then transfer everything to a slow cooker. Cook on LOW for 6 to 7 hours. The sauce will be slightly more liquid — remove the lid for the final hour to reduce it.
Can I add wine to this casserole?
Yes — replace 100ml of the stock with the same quantity of red wine. Add it after the tomato purée and let it bubble for two minutes before adding the tomatoes and remaining stock.
Why is my sausage casserole sauce too thin?
The lid was on during cooking. Cook uncovered for at least the final twenty minutes. If still thin, increase the heat slightly and cook for a further ten minutes, stirring regularly.
Can I add potatoes to the casserole?
Yes — quartered baby new potatoes or chunks of floury potato added with the sausages in the final stage of cooking will be tender after twenty-five minutes in the simmering sauce and make the casserole a complete one-pot meal.
