- 3 tbsp extra virgin olive oil
- 1 tsp bittersweet smoked paprika, plus extra to serve
- 2 sprigs fresh oregano, leaves only, chopped
- 1 garlic clove, finely chopped
- ½ tsp ground cumin
- 4 x 250g/9oz pork fillets (preferably Ibérico pork)
- 1kg/2lb 4oz waxy potatoes, such as Desirée potatoes, peeled, cut into 7-8mm-thick slices
- 2 tbsp olive oil, plus extra to serve
- 1 small onion finely sliced
- 3 garlic cloves, finely sliced
- 4 sprigs fresh thyme, leaves only, to serve
- salt and freshly ground black pepper
- For the pork, preheat the oven to 200C/180C Fan/Gas 6.
- Mix together all of the pork ingredients, except for the pork, in a large bowl until well combined. Add the pork fillets and coat them in the mixture. Chill in the fridge for at least 12 hours, to marinate.
- When the meat has marinated, remove it from the fridge and set aside until is has returned to room temperature.
- Heat an ovenproof frying pan over a medium heat. When the pan is hot, remove the pork fillets from the marinade, shaking off any excess, and fry for 1-2 minutes on each side, or until browned on all sides.
- Transfer the pan to the oven and cook the pork fillets for a further 5 minutes (if you are using ibérico pork, the fillets will only need cooking in the oven for 2 minutes). Remove the meat from the pan and set aside on a warm plate for 5 minutes, to rest. Reserve the pan juices.
- Meanwhile, for the potatoes, boil the potato slices in a pan of salted water for 1-2 minutes, or until just tender. Drain well.
- Heat the oil in a frying pan over a medium heat, then add the drained potatoes and fry for 2-3 minutes, or until just coloured.
- Add the onion and garlic and continue to fry for 1-2 minutes, or until golden-brown. Season, to taste, with salt and freshly ground black pepper.
- To serve, divide the potato mixture equally among 4 serving plates. Carve each pork fillet into slices and arrange the slices on top of the potatoes. Drizzle the pan juices and a splash of olive oil around the edge of each plate. Garnish with the thyme leaves.
