Jamie Oliver's take on a classic shepherd's pie, bulked out with cannellini beans for extra fibre and topped with a half-and-half swede and potato mash. The ragu is built on lean lamb mince, carrots, celery, mushrooms and onion, finished with mint sauce and Worcestershire sauce for a tangy lift. A layer of frozen peas sits between the ragu and the mash to stop the topping sinking. Source recipe is oven-baked at 180°C for 50 minutes; adapted here for the air fryer.
Air fryer notes: Source recipe bakes the assembled pie at 180°C in a conventional oven for 50 minutes. Adapted to 170°C for 30-35 minutes in the air fryer, as the more direct convection browns the scored mash top faster. Dish must be air-fryer-safe and fit the basket; for larger air fryers cook in one dish, for smaller models split between two smaller dishes. All hob steps (browning mince, simmering ragu, boiling swede and potatoes) are unchanged from the source.

Method
Place the lean lamb mince into a dry pan over a high heat. Break it up and let it brown and caramelise, rendering the fat out for plenty of flavour.
~5 minSeason the lamb with two generous pinches of black pepper and a little salt. Stir in the finely chopped rosemary.
~1 minAdd the finely chopped onions and the drained cannellini beans. Keep frying so everything continues to colour.
~3 minAdd the diced carrots, diced celery and the mushrooms. Stir over a high heat for around 10 minutes total until the veg has sunk down and softened.
~10 minStir in a heaped tablespoon of plain flour, then pour in 800ml of chicken or vegetable stock. Bring to the boil, cover with a lid and simmer for 30 minutes.
~30 minWhile the ragu simmers, boil the swede in salted water for 10-15 minutes, then add the quartered potatoes and boil for a further 10-15 minutes until both are tender.
~25 minTurn the ragu off and stir in 2 teaspoons of mint sauce and 1 tablespoon of Worcestershire sauce. Pour the ragu into an air-fryer-safe serving dish.
~2 minDrain the swede and potatoes well and mash with 2 tablespoons of semi-skimmed milk and the 15g of grated cheddar. Season to taste.
~3 minScatter the frozen peas in an even layer over the ragu, then spoon the mash on top of the peas. Use a fork to score the surface so the ridges catch and crisp.
~3 minPreheat the air fryer to 170°C. Place the pie in the basket and cook for 30-35 minutes until the top is golden and the gravy is bubbling at the edges.
~35 minAbout 5 minutes before the end, scatter a few rosemary sprigs and a small drizzle of olive oil over the top.
~5 minRest the pie for 5 minutes before serving up generous portions.
