Mary Berry Minted Lamb Casserole Recipe Ingredients
- 900 g (2 lbs) lamb shoulder or leg, cut into 1 inch cubes
- 2 tbsp sunflower oil
- 25 g (1 oz) butter
- 2 large onions, chopped
- 3 carrots, sliced into thick rounds
- 2 celery sticks, sliced
- 3 tbsp plain flour
- 600 ml (1 pint) lamb or beef stock
- 2 tbsp mint sauce (from a jar)
- 1 tbsp redcurrant jelly
- 1 tsp dried thyme
- Salt and freshly ground black pepper
- 2 tbsp fresh mint, chopped for garnish

How To Make Mary Berry Minted Lamb Casserole
- Preheat and sear the lamb: Start by preheating your oven to 160 C (325 F). Heat the sunflower oil in a large, flameproof casserole dish over high heat. Brown the lamb cubes in batches until they are dark and caramelized on all sides. This browning process is the most important step for developing a deep, savory flavor, so don’t rush it. Remove the meat and set it aside on a plate.
- Sauté the vegetables: Lower the heat to medium and add the butter to the same pan. Stir in the chopped onions, carrots, and celery. Cook them for about 8 to 10 minutes until the onions are soft and have started to take on a little golden color from the lamb juices left in the pan.
- Thicken the gravy base: Sprinkle the plain flour over the softened vegetables and stir well for 1 minute. This ensures the flour is cooked through and won’t leave a “starchy” taste in your finished sauce.
- Add the liquids and aromatics: Gradually pour in the lamb or beef stock, stirring constantly to prevent any lumps from forming. Add the mint sauce, redcurrant jelly, and dried thyme. The redcurrant jelly is the secret ingredient here—it adds a subtle sweetness and a beautiful glossy sheen to the gravy.
- Simmer and transfer to the oven: Return the browned lamb and any juices from the plate back into the casserole dish. Bring the mixture to a gentle simmer on the stovetop, then cover with a tight-fitting lid. Place the dish in the preheated oven and cook for 1 hour 30 minutes to 2 hours.
- Final check for tenderness: After 90 minutes, check the lamb. It should be “melt-in-the-mouth” tender. if it still feels a little firm, give it another 15 to 20 minutes. Taste the sauce and adjust the salt and pepper to your liking.
- Garnish and serve: Just before serving, stir in half of the fresh chopped mint. Ladle the casserole into warm bowls and sprinkle the remaining fresh mint over the top for a bright, aromatic finish.

Recipe Tips
- How to choose the best cut of lamb: Lamb shoulder is the best choice for a casserole because it has a bit more fat than the leg, which melts away during the slow cook to keep the meat incredibly juicy.
- Why use mint sauce and fresh mint: Using mint sauce from a jar provides a vinegar-based tang that cuts through the richness of the lamb, while the fresh mint added at the end provides that unmistakable “garden-fresh” aroma.
- How to get a glossy sauce: Ensuring you whisk the stock in slowly and adding that tablespoon of redcurrant jelly is the best way to achieve a professional, silk-like finish to your gravy.
- Can I add more vegetables: Absolutely! This recipe works beautifully with added leeks or even some baby pearl onions added halfway through the cooking time.
