These king oyster mushroom ribs are spookily meaty. In fact they may well be the 'meatiest' vegan dish we've ever created! We arranged ours on some gorgeous BBQ mash to create a super scary ribs cage! Perfect for a halloween spread.

Weather your celebrating the ghoulish season or not, we strongly recommend you try these ribs! They will impress even the staunchest meat eater.



Ribs Cage

  • 20 king oyster mushrooms
  • 6 tbsp olive oil (more for greasing)
  • 3 tbsp BBQ seasoning
  • 250g BBQ sauce
  • 3 tbsp crispy onions
  • ½ tbsp chilli flakes
  • Salt and pepper to taste

Caramelised Onion Mashed Potatoes

  • 1kg maris piper potatoes
  • 2 tbsp vegan butter
  • 4 tbsp vegan milk
  • 2 large red onions
  • 1 tbsp olive oil
  • 1 tbsp vegan butter
  • 2 large red onions
  • ½ tsp salt
  • ½ tsp black pepper
  • ½ tsp sugar
  • 1 tsp garlic puree
  • 2 tbsp BBQ seasoning


  1. 1.

    Prepare the mushrooms | Cut the caps off the king oyster mushrooms and set to one side | Cut the long edges off the mushrooms to make them look more like ribs | Put the cut offs in the same place as the caps

  2. 2.

    Marinade the mushrooms | Add the bbq seasoning and olive oil to a mixing bowl and mix to make a marinade | Add the mushroom “ribs” to the bowl and toss to coat in the marinade

  3. 3.

    Sear the mushrooms | Warm a large frying pan over a medium heat | Add half the mushrooms to the pan and fry them all for 30 seconds on each side, turning with tongs | Once all the ribs have been seared on all sides, press the mushrooms with a potato masher to squeeze out excess moisture and to seal the firm up the edges | Take the prepared mushrooms out of the pan and set to one side | Repeat with the remaining mushrooms

  4. 4.

    Prepare the Ribs Cage | Line a large baking tray with tin foil (make sure the whole length of the baking tray is covered with tin foil | Brush the tin foil with a little olive oil | Pour ⅓ of the bbq sauce into the middle of the tin foil and spread it with the back of a spoon, making sure you leave a 2 inches of foil exposed on either side of the foil | Lay the mushroom “ribs” down the middle of the tin foil in a rib-like formation | Drizzle ⅓ of the bbq sauce over the ribs | Wrap the Ribs Cage in the tin foil parcel | Put the baking tray in the oven and roast the Ribs Cage for 25 minutes | Take the tray out of the oven, open the parcel, drizzle the remaining bbq sauce over the ribs and put the tray back in the oven for a further 15 minutes

  5. 5.

    Whilst the ribs are roasting, make the Mashed Potatoes | Peel the potatoes and cut any big ones in half | Put the potatoes in a large saucepan | Cover the potatoes with cold water and add a pinch of salt | Put the pan on the stove over a high heat, bring to the boil and cook until the potatoes are tender (roughly 12-14 minutes) | Drain the potatoes and put them back in the pan they boiled in | Add the vegan butter and vegan milk to the pan and mash until creamy | Taste the potatoes and lightly season with salt and pepper | Leave the potatoes on the stove over a very low heat and stir every couple of minutes so they stay warm

  6. 6.

    Prepare the caramelised red onions | Peel and finely slice the red onions | Finely slice the remaining mushrooms | Warm the olive oil and vegan butter in a frying pan over a medium | Add the red onion to the pan and stir for 2 minutes | Add the mushrooms to the pan and stir for 2 minutes | Add the salt, pepper, sugar, garlic puree and bbq seasoning to the pan and stir for 4-5 minutes

  7. 7.

    Finish the Caramelised Onion Mashed Potatoes | Add the contents of the frying pan to the saucepan and fold the caramelised onion mixture into the potatoes | Taste the potatoes and season to perfection with salt and pepper

  8. 8.

    Finish the Ribs Cage with Caramelised Onion Mashed Potatoes | Take the baking tray out of the oven and open up the tin foil | Spoon the potatoes into the tin foil at the bottom of the rib cage | Sprinkle the crispy onions and chilli flakes over the ribs and bring the tray the table as a centrepiece | Plate up the potatoes with the ribs, add a small side salad if you fancy!
