Frazzled Thyme Onions

These simple crispy onions are the ideal topping for a burger or addition to a salad or sandwich. Is this worthy of posting as a recipe? Yes, because they are crispy, sweet and delicious, and the kind of thing you might overlook. It’s the extras like this that can make a sandwich or burger into something really special.

  1. mmm, I love onions done like this! There was a burger I used to get (pre-vegan) that was topped with them, it was my favorite simply for those onions. Why did I never think to make them myself?

    Funny thing, I just saw a chocolate cake topped with, would you believe it, frazzled onions! So, I guess, they’re not just for salads and sandwiches ๐Ÿ™‚

    1. That’s unbelievable! – onions on choc cake seems like a step too far! But do make them for savoury dishes – I don’t usually like to deep fry but sometimes you just have to ๐Ÿ˜‰

    1. I know what you mean – I try to avoid deep frying too. At least these don’t need a proper deep fryer, you can do them in 1-2 cm of oil in a saucepan too! It’s just what to do with all the oil when you’ve finished!!

  2. Lucy, I was very excited when I read your mushroom burger recipe in the Guardian, today I am in the middle of cooking it and find that the Guardian left out the vital 2cm of oil from their printing (I photocopied it). I found your site on line and see that 2cm of oil should have been added whereas they wrote – dryfry the mushrooms. Consequently I have just tried to use my blender but it almost exploded because everything is too dry (and the mushrooms were very difficult to ‘dry fry’ as the recipe said – special dinner tonight including my vegetarian son and family and wanted to surprise him with something new – I have no time to redo it so am going to add a little oil to the blender and see if this does it. I don’t have time to look at your site now but will definitely do so. Thanks, Della

    1. Thanks for your comments and I hope you enjoyed the burgers. I did indeed dry fry my mushrooms and found that with un rinsed beans, the chipotle sauce and the moisture from the veg, I didn’t need to add any more liquid/oil. However, I’m sure frying in a small amount if oil would work fine too, especially if you don’t have a reliable non-stick frying pan. I think the 2cm of oil refer to frying the frazzled onions that go on top.
