This cozy, comforting Jamie Oliver Lamb Casserole is everything you want in a hearty dinner. Packed with tender chunks of lamb, smoky bacon, and a medley of root vegetables simmered in a rich broth, it’s a dish that feels like a warm hug on a chilly evening. I made this last Sunday and the whole house smelled amazing all afternoon. It’s definitely going into our regular winter rotation! (inspired by Jamie Oliver)
Ingredients Needed
- 3 bay leaves
- 50g plain flour
- 1.4–1.5kg boneless shoulder or leg of lamb, trimmed and cut into 3cm pieces
- 2–3 tbsp sunflower oil
- 100g unsmoked bacon lardons or pancetta
- 1 large onion, chopped
- 6 medium carrots (about 600g), peeled and chopped
- 4 large celery sticks, sliced
- 4 garlic cloves, crushed
- 1 tbsp chopped fresh rosemary
- 1 tbsp tomato purée
- 750ml chicken or lamb stock
How To Make Jamie Oliver Lamb Casserole
- Coat and Brown the Lamb:
Start by seasoning the flour with a little salt and pepper, then toss the lamb pieces in it until fully coated. Shake off any excess flour. Heat 2 tablespoons of sunflower oil in a large, flameproof casserole dish and brown the lamb in batches. Set the browned meat aside. - Cook the Base:
In the same dish, cook the bacon over medium heat until golden. Add the chopped onion and a splash more oil if needed. Sauté for about 5 minutes until the onion begins to caramelize. Add the celery and carrots, cover, and let them soften for another 5 minutes. - Layer in the Flavor:
Remove the lid, stir in the rosemary and crushed garlic, and cook for 1 more minute. Sprinkle in any leftover flour from earlier. Stir well, then add the tomato purée, stock, and bay leaves. - Simmer and Soften:
Return the browned lamb to the pot, stir to combine, and bring everything to a gentle boil. Reduce the heat to low, partially cover the dish, and simmer for about 1½ hours. Stir occasionally and check that nothing’s sticking to the bottom. The lamb should be fork-tender and the sauce thickened. Discard the bay leaves and adjust seasoning to taste.

Why I Love This Recipe
This is the kind of meal that feels like home. I made it for a family dinner and everyone—from my fussy eater nephew to my soup-loving gran—had second helpings. The slow-cooked lamb melts in your mouth, and it’s so flexible. Sometimes I swap in root veg or even chuck in a tin of beans to bulk it out.
