Aubergine steaks with miso & peppercorn sauce

Aubergine steaks with miso & peppercorn sauce

Aubergine and miso are a cult combo – and this dish shows you why. Griddling then roasting the aubergines coaxes out a nutty, mildly sweet flavour, with a velvety texture and caramelised edges. A creamy miso and green peppercorn sauce ups the umami ante perfectly, while herby, lemony rice packed with green beans keeps things fresh and bright.

Before you start

  • 1x non-stick frying pan
  • 1x baking tray lined with baking paper
  • 1x saucepan

Slice, sear & roast

  • Heat your oven to 220ºC/fan 200ºC/gas 7/air fryer 200ºC.
  • Halve each aubergine lengthways then, placing them cut-sides down, trim off the rounded sides to form 2 thick, flat steaks.
  • Spritz a large non-stick frying pan (or non-stick griddle pan) with cooking spray and put it over a medium-high heat. Fry the aubergines for 2-3 mins on each side.
  • Transfer the aubergines to a baking tray lined with baking paper (or into the air-fryer basket) and roast for 12-15 mins (air-fry for 10-12 mins), until very soft.

Boil the rice

  • Meanwhile, trim the green beans and cut into 2cm pieces.
  • Cook the rice in boiling water for 10-12 mins, adding the green beans for the final 3-4 mins, then drain and return to the pan.

Ace the base!

  • At the same time, peel and finely dice the onions.
  • Spritz the frying pan with more cooking spray and put it over a medium heat. Fry the onions and peppercorns for 5-7 mins.

Set the sauce simmering

  • Add the miso, then crumble in the stock, pour in 150ml water (250ml for 4 portions) and stir well. Simmer for 3-4 mins (5-6 mins for 4 portions), until the sauce reduces to loosely coat the onions.
  • Take the pan off the heat and leave to cool a little, then stir in the yogurt.

Add your final flourishes

  • Zest the lemon, and finely chop the thyme leaves, then stir both through the rice along with the garlic paste.
  • Squeeze a little lemon juice (to taste) into the rice and the sauce.
  • Divide the rice and sauce between plates, then lay the aubergine steaks on top and serve.
