Ingredients

  • 1 small oyster mushroom cluster, see notes

Balsamic Marinade

  • 2 tbsp vegetable or olive oil
  • 1 tbsp balsamic vinegar
  • 2 tsp maple syrup or honey
  • 2 cloves garlic, minced
  • 1 tsp soy sauce

Instructions 

  • Prepare your marinade by whisking all ingredients together in a bowl until emulsified.
  • Place your oyster mushroom cluster in a dish large enough for it to lay flat. Pour the marinade over the top.
  • Use a brush or spatula to mix the marinade through the cluster, ensuring that every bit is coated. If you have any loose mushroom caps, just tuck them into the cluster somewhere.
  • While the mushroom marinates, we need to weigh it down to help it flatten. So find a smaller dish (the heavier the better) to place on top of the mushrooms, then fill that dish with some other heavy items. Place it in the fridge for at least 15 minutes.
  • When you're ready to cook, heat your air fryer to 180C (390F) and place the mushroom cluster in the basket. Use a spatula to press it down to help flatten it more before closing the basket.
  • Cook for 8-10 minutes, until the edges are caramelized and the mushroom is reduced and cooked through. During the cooking process, I like to go in 2-3 times to press down on it again with the spatula, helping it come together in a dense cluster (especially if my cluster has some breakaway caps). I usually end up pushing it into the corner to aid that process, as you can see in the photos. I don't feel the need to flip it over at any point, because the air fryer I use allows for very even air flow. If you're using an air fryer liner, you may want to flip it.
  • Once you're happy with the done-ness of it, lift it out of the air fryer basket and serve immediately.

Notes

Oyster mushroom cluster size: This recipe was tested on oyster mushroom clusters that were 150g (5.3oz) in size. Larger clusters could be used - just be mindful to scale up the marinade recipe. 
If you're only making one of these, it will easily fit into a compact air fryer. When making two, you will need something a little larger.
