Ingredients
 

  • 4 king oyster mushrooms (approx. 10 oz / 300 g)
  • 2 tablespoons tamari (or soy sauce if not GF)
  • 1 tablespoon sesame oil
  • 2 cloves garlic, minced or finely chopped
  • 1 inch piece of ginger, minced or finely chopped
  • 1 fresh chilli, finely chopped
  • Juice of half a lime

Instructions
 

Marinade

  • In a large freezer bag or bowl, mix together all of the ingredients apart from the mushrooms. The great thing about a freezer bag is that you can use your hands to combine everything without any mess.
  • Cut each mushroom lengthways into three slices, then add these to the marinade bag/bowl. Take a couple of minutes to coat the mushrooms evenly in the marinade, then leave for approx. 15 minutes on the work surface or in the fridge. Again, a freezer bag makes it easy to move everything around and you can use the zip seal to help trap the flavour.

BBQ/grill

  • Preheat the barbecue/grill to a medium heat (not scorching hot or else the mushrooms will quickly burn and/or dry out). Add the mushroom slices and cook for approx. 5 minutes on each side, doing this in batches if necessary. The mushrooms should be golden on both sides with slightly crispy edges and char marks.

Pan-fry

  • To pan-fry these mushrooms you'll probably have to cook in batches. Heat a small amount of cooking oil in a pan on medium heat and add the mushroom slices, avoiding any overlaps. Cook for 3-4 minutes on either side, or until both sides are golden with slightly crispy edges. Transfer to a plate and repeat with the remaining mushrooms.

Notes

Leftover marinade: If you have leftover marinade, don't throw that stuff away! Use it in a stir-fry, soup, or stew, or recycle it with more soy sauce and sesame oil to then marinate something else.
Quantity: Four mushrooms will provide twelve thin mushroom 'steaks'. This is a nice amount for two main servings, or can provide many more servings as a side.
Marinating time: I find that anywhere from 15-30 minutes is a good window for marinating mushrooms. You could also prepare them further in advance – just be aware that the mushrooms will probably become softer over time.
Cooking time: This will vary slightly depending on the type of barbecue/grill and the cooking temperature. It's best to check the mushrooms after a few minutes to see if they've turned golden underneath.
Gluten-free: Tamari is a variant of soy sauce that’s usually gluten-free. If this recipe needs to be 100% gluten-free, make sure you use tamari or a GF soy sauce.
Storage: You can store the cooked mushrooms in the fridge for up to a week. While it's possible to freeze the mushrooms, I'd avoid this as it'll affect the texture and taste.
