Prep Time: 30 min

Cook time: 1.5 hr

Yield: 5 servings


Portobello steaks

  • 4 portobello mushrooms

  • 5 cloves garlic, peeled

  • 1/2 onion, peeled and cut into 6 wedges

  • 1/2 tbsp chipotle chilli flakes

  • 2.5 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

  • sea salt

  • 3/4 cups +3 tbsp olive oil

White bean purée

  • 1 x 700g can of white beans (any type)

  • 1 1/2 tbsp lemon juice

  • 1 tbsp olive oil

  • sea salt



  1. Preheat oven to 325F.

  2. Put all the ingredients for the 'steaks' and 1 tbsp sea salt into a large oven safe pan, with a lid. 

  3. Arrange the mushrooms so they are dome side up, then top with a piece of parchment paper, pushing it down to cover all the ingredients. Cover with the lid, and put in the oven for 1 hour.

  4. Turn the mushrooms over, replacing the paper and lid and return to the oven for 20 minutes more.

  5. Use a pair of tongs to remove the mushrooms to a cutting board. Slice them in half and set aside.

  6. Save the remaining ingredients in the pot to spoon over your finished dish.


  1. Reserve 1/3 of the beans and set aside. Put the remaining beans into a food processor (or blender) along with the lemon juice, olive oil and 1/2 tsp salt.

  2. Blend until completely smooth. Transfer to a medium saucepan, add the whole beans to the pot and cook on a medium heat for about 5 minutes, stirring until warmed through.

Plate the portobellos on top of the purée and drizzle with the ingredients from the mushroom pot.
