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.
Ingredients
Portobello steaks
- 8 medium to large portobello mushrooms (about 650 g), stems removed
- 10 garlic cloves, peeled
- 1 onion, peeled and cut into 6 wedges (150 g)
- 4½ tsp chipotle chilli flakes
- 1 red chilli (15 g)
- 4 tsp cumin seeds, roughly crushed in a pestle and mortar
- 3 tsp coriander seeds, roughly crushed in a pestle and mortar
- 1½ tbsp (30 ml) tomato paste
- 400 ml olive oil
Butter bean mash
- 700 g jar good quality cooked large butter beans, drained (500 g) (see Note)
- 4½ tsp (22 ml) lemon juice
- 3 tsp (15 ml) olive oil
- flaked sea salt
Instructions
1. Preheat the oven to 150°C fan-forced.
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 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 1½ tablespoons (30 ml)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).
Note
• We use Brindisa Navarrico large butter beans, but you can, of course, use tinned or cook your own.
