  • oven fries, to serve (optional)


  1. Heat oven to 220C/200C fan/gas 7. Mix the onion with the oil and vinegar, spread on a baking tray, then put the mushrooms on top, stem-side up, and scatter over the thyme and some seasoning. Cook in the oven for 15 mins, until starting to soften and caramelise.

  2. Crumble the cheese into the cavity of the mushrooms and cook for 5 mins more until the cheese is melted and bubbling.

  3. Split the ciabatta roll in half and lightly toast. Top with a handful of rocket, the sticky onions and the cheese-topped mushrooms. Serve with oven fries, if you like.

I've made this burger a handful of times as they're so easy to throw together and perfect for a treaty weekend tea. I recommend using a strong blue cheese as more subtle flavours get lost. Also go easy on the balsamic, the mushrooms release a lot of water so one tablespoon of balsamic is enough otherwise you get a soggy mess.

Simple and yummy for a mid weeker. Did it with some amazing french blue cheese that came straight from Paris to me! Good quality mushrooms and cheese make all the difference :)

OK - by the time it was cool enough to eat, the bread was soggy. Tried with roquefort but didn't really like it - may try again with stilton.

Really really tasty. I especially like the balsamic vinegar on the onions. And the thyme works well with the blue cheese (we used Shropshire Blue)... My boyfriend was very happy with it!

Really yummy. Did them with goats cheese & even non-veggies were happy!
