Jamie Oliver Shepherd's Pie in the Air Fryer

Jamie's shepherd's pie sneaks beans and mushrooms into the meat layer to bulk it out brilliantly, then tops it with a mash that's half swede for extra veg. A splash of mint sauce finishes the ragu with that classic lamb-and-mint magic.

How To Make A Shepherds Pie | Comfort Food By Jamie Oliver

Source video by Jamie Oliver on YouTube. This recipe was adapted with strict source-fidelity rules and is marked for human review.

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.

Ingredients

Ragu
  • lean lamb mince
  • 2 generous pinchblack pepper
  • salt
  • 2 sprigfresh rosemary, finely chopped
  • 2 wholeonions, finely chopped
  • 1 tincannellini beans, drained
  • 2 wholecarrots, diced
  • 2 wholecelery sticks, diced
  • 250 gmushrooms
  • 1 heaped tbspplain flour
  • 800 mlchicken or vegetable stock
  • 2 tspmint sauce (add late)
  • 1 tbspWorcestershire sauce (add late)
Topping
  • 800 gpotatoes, quartered
  • swede, peeled and chopped
  • 2 tbspsemi-skimmed milk
  • 15 gmature cheddar cheese, grated
  • 350 gfrozen peas
  • rosemary sprigs (add late)
  • olive oil (add late)

Method

  1. 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 min
  2. Season the lamb with two generous pinches of black pepper and a little salt. Stir in the finely chopped rosemary.

    ~1 min
  3. Add the finely chopped onions and the drained cannellini beans. Keep frying so everything continues to colour.

    ~3 min
  4. Add 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 min
  5. Stir 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 min
  6. While 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 min
  7. Turn 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 min
  8. Drain the swede and potatoes well and mash with 2 tablespoons of semi-skimmed milk and the 15g of grated cheddar. Season to taste.

    ~3 min
  9. Scatter 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 min
  10. Preheat 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 min
  11. About 5 minutes before the end, scatter a few rosemary sprigs and a small drizzle of olive oil over the top.

    ~5 min
  12. Rest the pie for 5 minutes before serving up generous portions.

    ~5 min

Frequently asked

Can I really cook a shepherd's pie in an air fryer?
Yes, as long as your air fryer is big enough to hold an oven-safe dish that fits the basket with airflow around it. The air fryer's strong convection actually crisps the scored mash topping beautifully. For smaller models, split the pie between two smaller dishes and cook them one at a time, or back-to-back.
Do I need to preheat the air fryer?
Yes, 2-3 minutes at 170°C helps the top start to colour straight away rather than steaming. The ragu underneath is already hot from the hob, so you're really just baking on the topping.
Can I make this vegetarian like Jamie suggests?
Yes. Swap the lamb mince for an extra 300-400g of mushrooms (a mix of chestnut and any wild mushrooms works well) and use vegetable stock. Keep everything else the same. You may want to cook it slightly drier on the hob as mushrooms release a lot of water.
Can I make it ahead and reheat in the air fryer?
Yes. Assemble the pie, cool, cover and refrigerate for up to 2 days. To reheat from cold, cook at 160°C for 25-30 minutes, then bump up to 180°C for the final 5 minutes to re-crisp the top. Make sure the centre is piping hot before serving.
Why put frozen peas between the ragu and the mash?
Jamie's trick: the peas act as a barrier that stops the mash sinking into the gravy, so you keep a defined, crispy potato layer on top. They also add extra veg and a pop of sweetness through each spoonful.
