Portobello steaks and butter bean mash

A vegetarian recipe that is simply as good as any steak (with mash), if not better.

SERVES 4
As a main

We’re not mad about calling vegetables a ‘steak’ or ‘burger’ or ‘schnitzel’, because it feels like you are trying to pass them off as something else, something superior. Vegetables are great simply as they are. In fact, they are the best! Sometimes, though, using a meaty name helps you understand what’s going on and how delicious it is. Our portobellos aren’t trying to be a steak, they are simply as good as any steak (with mash), if not better; in just the same way as our Romano pepper schnitzels are as delectable as any other schnitzel. What gives the mushrooms their verve is the chillies and spices and all the flavoured oil that coats them. You’ll make more oil than you need here; keep it refrigerated in a sealed container to spoon over grilled vegetables, noodles, meat or fish. Serve this with some sautéed greens, if you like.

PORTOBELLO STEAKS

  • 8 medium to large portobello mushrooms (about 650g), stems removed
  • 10 garlic cloves, peeled
  • 1 onion, peeled and cut into 6 wedges (150g)
  • 1½ tbsp chipotle chilli flakes
  • 1 red chilli (15g)
  • 4 tsp cumin seeds, roughly crushed in a pestle and mortar
  • 1 tbsp coriander seeds, roughly crushed in a pestle and mortar
  • 2 tbsp tomato paste
  • 400ml olive oil

BUTTER BEAN MASH

  • 1 × 700g jar of good-quality cooked large butter beans, drained (500g) (we use Brindisa Navarrico large butter beans, but you can, of course, use tinned or cook your own)
  • 1½ tbsp lemon juice
  • 1 tbsp olive oil
  • flaked sea salt

1. Preheat the oven to 150°C fan.

2. Put all the ingredients for the steaks and 1 tablespoon of flaked salt into a large ovenproof saucepan, for which you have a lid. Arrange the mushrooms so they are domed side up, then top with a piece of parchment paper, pushing it down to cover all the ingredients. Cover with the lid, then transfer to the oven for 1 hour. Turn the mushrooms over, replacing the paper and lid, and return to the oven for 20 minutes more, or until the mushrooms are very tender but not falling apart. Use a pair of tongs to transfer the mushrooms to a chopping board, then cut them in half and set aside.

3. Use a spoon to remove the onion, garlic and chilli (discarding the stem) – don’t worry if you scoop up some of the spices and oil. Put them into the small bowl of a food processor and blitz until smooth. Return the blitzed onion mixture to the saucepan, along with the mushroom halves, and place on a medium-high heat. Cook for about 5 minutes, for all the flavours to come together.

4. While the mushrooms are cooking, make the mash by putting the beans into a food processor along with the lemon juice, olive oil, ½ teaspoon flaked salt and 2 tablespoons of water. Blitz until completely smooth. Transfer to a medium saucepan and cook on a medium-high heat for about 3 minutes, stirring, until warmed through.

5. To serve, divide the butter bean mash between four plates. Top with four mushroom halves per plate and spoon over a generous amount of the oil and its accompanying aromatics (you won’t need all of it, though – see intro).
