A one-pot Lamb recipe with Spanish flavors, built for busy weeknights when you want real food without a sink full of dishes. Comes together in roughly 43 minutes, serves about 4, and uses ingredients you can find at any normal grocery store. The technique is simple: build a base in your pot, layer in the main ingredients, simmer until everything has had time to talk to each other, and serve straight from the pan. If you're cooking for picky eaters, this one tends to land — the flavors are recognizable, the texture is comforting, and there's nothing weird hiding in the ingredient list. Perfect for the kind of evening where you want dinner on the table by 7pm and the kitchen empty by 7:30.

2.5kg Lamb Shoulder
1 tblsp Olive Oil
2 chopped Onion
4 Chopped Carrots
1 Garlic Bulb
500ml Chicken Stock
1200g Butter Beans
450g Roasted Pepper
300g Black Olives
4 tablespoons Parsley
4 Cloves Crushed Garlic
1 tablespoon Hot Smoked Paprika
4 tablespoons Olive Oil
1/2 teaspoon Rosemary

Step-by-step instructions

To make the spice mix, combine all of the ingredients together with a large pinch of salt. Slash the lamb shoulder all over with a sharp knife and rub in. If you have the time, marinate for up to 24 hrs, but this is not essential.
Heat the oven to 150C/130C fan/gas 2. Heat the oil in a large flameproof casserole dish or roasting tin over a medium-high heat, add the onions, carrots and garlic and sizzle for 5 mins until the onions and carrots are softened. Pour over the stock, then bring to the boil. Nestle the lamb in the pan and cover, then transfer to the oven and roast for 2 hrs.
Uncover and transfer the lamb to a plate using tongs. Stir the beans, peppers and olives through the stock in the pan, sit the lamb back on top and return to the oven, uncovered, for 1 hr 30 mins until the lamb is cooked through. Transfer the lamb to a board and shred using two forks. Stir the parsley through the braised beans before serving.

Why this works on a weeknight

Spanish-style slow-cooked lamb shoulder & beans lands at about 56 minutes total — a little longer than our 30-minute target, but most of that time is hands-off simmering, which is why it earned a spot in our Sheet-Pan Dinners collection. The technique is forgiving, the ingredient list is grocery-store standard, and the active cooking time is short enough that you can answer a text message in the middle without ruining dinner.

Cleanup notes

This is a single-pan recipe, so the cleanup is exactly one pan, one cutting board, and one knife. While the dish rests, fill the pan with hot soapy water — by the time you are done eating, the residue lifts off with a single pass of a sponge. Skip the steel wool on cast iron; a stiff brush and warm water are all you need to keep the seasoning intact.

Make-ahead and leftovers

Leftovers keep covered in the fridge for up to three days. Reheat in a dry pan over medium-low with a splash of water or stock to loosen the sauce. Spanish-style slow-cooked lamb shoulder & beans actually improves overnight as the flavors keep talking to each other, so doubling the recipe and packing tomorrow's lunch is a high-leverage weeknight move.
