A good lamb casserole starts with patience, not a special cut. Shoulder and neck are worked muscles, full of connective tissue that turns tough if you rush it and meltingly tender if you don’t. Red wine and a long, slow braise break that collagen down until the meat gives way at the touch of a fork — the reason a pot like this one has been a fixture of Sunday tables for generations.
It starts on the stove, browning the lamb hard in Wilson’s Rosemary Flavoured Oil before the wine goes anywhere near the pot. That first sear is where most of the flavour comes from, and rosemary has always belonged with lamb.
Here is how we put it together, from browning to the last half hour with the potatoes in.
Lamb Casserole with Red Wine
Ingredients
Method
- Preheat the oven to 160C.
- Pat the lamb dry and season generously with salt and pepper.
- Heat Wilson's Rosemary Flavoured Oil in a large casserole pot over medium-high heat. Brown the lamb in batches until deeply coloured on all sides, then set aside.
- Reduce the heat to medium. Add the onions, carrots and celery to the pot and cook for about 8 minutes, until softened.
- Stir in the garlic and flour and cook for 1 minute, stirring so it doesn't catch.
- Pour in the red wine, scraping up the browned bits from the bottom of the pot, and let it simmer for 2 minutes.
- Return the lamb to the pot along with the stock, tomato paste, bay leaves and rosemary sprigs.
- Bring to a gentle simmer, cover, and transfer to the oven. Braise for 2 hours.
- Add the baby potatoes, return the pot to the oven uncovered, and cook for a further 30 minutes, until the lamb is tender and the potatoes are cooked through.
- Remove the bay leaves and rosemary sprigs, taste and adjust the seasoning, and serve.
Notes
We Use Rosemary Flavoured Oil
Browning the lamb properly is not optional in a dish like this. A hard sear on all sides builds the base layer of flavour the whole casserole relies on, and it needs an oil that can take real heat. Wilson’s Rosemary Flavoured Oil does that job and works double duty, since rosemary is one of the few herbs that holds its own against a cut as rich as lamb.
Rosemary and lamb is about as classic a pairing as South African kitchens have. Cooking the herb into the oil rather than scattering dried leaves in near the end means it is there from the very first minute, coating the meat before the wine and stock even go in.
That matters most in a long braise. Two and a half hours in a low oven mutes a lot of delicate flavours, but starting with the rosemary carried in oil, right against the meat, means it survives the distance.
Our Tips
Brown in batches. Crowding the pot steams the lamb instead of browning it, and you lose the base flavour that the rest of the casserole is built on.
Don’t skip the flour. Stirred in with the vegetables, it thickens the gravy naturally as it braises, so there’s no last-minute thickening to worry about.
Add the potatoes later, not at the start. Going in for the final thirty minutes only, they hold their shape instead of turning to mush.
Let it rest before serving. Ten minutes off the heat with the lid on lets the sauce settle and the flavours even out.
Taste before you add salt. Stock and wine reduce differently every time, so check right at the end rather than seasoning early.
Low and slow beats hot and fast. A gentle oven does more for tough cuts than a hot one ever will — resist the urge to turn the temperature up to save time.
How We Serve It
This is a spoon-and-fork dish, so it wants something underneath to soak up the gravy. A pile of buttery mash does the job well, and so does a thick slice of crusty bread pulled straight from the loaf.
For a proper Sunday lunch, put the pot in the middle of the table and let everyone help themselves, with a bowl of buttered greens or steamed spinach alongside to cut through the richness.
Whatever red wine went into the pot is usually the right one to pour alongside it too.
More Ways to Use Rosemary Flavoured Oil
Once the bottle of Wilson’s Rosemary Flavoured Oil is open, it doesn’t need to stop at this casserole. It earns its keep across a few other regulars in our kitchen.
For a Sunday potjie — brown the meat in it before anything else goes into the pot, the same way we do with the lamb here, in our Beef Shin Potjie with Fluffy Dumpling.
For something from the sea — a drizzle finishes off fishcakes beautifully, as it does in our Snoek Fishcakes with Rosemary Oil Drizzle.
For a French classic done our way — it browns the chicken and carries through the sauce in our Coq au Vin.
For roast vegetables — toss potatoes or mushrooms in it before they go in the oven, and they come out with real rosemary flavour instead of just a dusting of dried herb.
For steak night — brushed on before the pan or the fire, it does the same job it does for the lamb, building flavour from the very first sizzle.
The Good Stuff About This Lamb Casserole
A herb-infused oil carries flavour differently to dried herbs shaken in near the end. Because the rosemary character is already dissolved through the oil, it spreads evenly from the first sear and holds up through a long braise in a way that a spoonful of dried leaves, added late, often can’t match.
Wilson’s Rosemary Flavoured Oil pairs well with chicken, lamb, pork, steaks and fish, and works just as well with mushrooms, potatoes, peas and spinach. It’s a regular for Sunday lunches and braai marinades in kitchens across South Africa.
It comes in 250ml and 1L bottles, with 6x250ml and 12x1L case options for anyone who goes through it as fast as we do.
Ways to Change It Up
Swap the wine. A dry red is classic, but a full-bodied dry white works if that’s what’s open.
Add mushrooms. Stirred in with the vegetables, they soak up the gravy and add another layer of savouriness.
Take it to the fire. The same method works over coals in a cast-iron potjie pot for a proper outdoor version.
Use lamb shanks instead. They braise beautifully and look striking served whole, one per plate.
Stir through olives near the end. A handful of pitted black olives adds a briny edge that plays well against the wine.
Questions You Might Have
What cut of lamb works best for this casserole?
Shoulder or neck are ideal. Both have enough connective tissue to break down during the long braise and come out tender rather than dry.
Can I make this ahead of time?
Yes, and it’s often better the next day once the flavours have had time to settle. Cool it fully, keep it covered in the fridge, and reheat gently on the stove.
Can I freeze lamb casserole?
It freezes well for up to three months. Freeze it without the potatoes if you can, as they can go grainy, and add fresh ones when you reheat.
What can I use instead of red wine?
Extra beef or lamb stock with a splash of balsamic vinegar gives a similar depth if you’d rather leave the wine out.
Why brown the lamb before braising?
Browning builds flavour that a long simmer alone can’t create. It’s a step worth the extra ten minutes it takes.
What should I serve with lamb casserole?
Mash, crusty bread or buttered greens all work well alongside it, depending on how hungry the table is.
Where can I buy Wilson’s Rosemary Flavoured Oil?
It’s available to order directly from oliveoil.co.za and at leading retailers across South Africa.
