LUNCH HeaderBurgers are my weakness. There, I said it. Of course, this poses a few problems when eating paleo since the very vehicle that holds the burger together is usually not paleo-friendly. 

If you’re hankering for a burger but still wanting to stick to your plan, either check out our Five Alternatives to Sandwiches post for some ideas on how to replace bread, or give this recipe for Portobello Mushroom Burgers below a try. 

I first came across this recipe in Jess’ Underground Kitchen Cookbook – she’s one of my favourite chefs in Auckland, cooking up delicious, unpretentious food for collection on your way home from work in Auckland. The meals are made with fresh, high-quality ingredients and there is always a paleo option. She has just recently opened up a cafe and deli which you can visit in addition to her meals, so if you’re ever heading down Jervois Rd in Ponsonby and desperately need a coffee, make sure you check it out!

We made these Portobello Mushroom Burgers on a crazy hot day during the peak of Auckland summer and they were deliciously good – I’d highly recommend them for a BBQ dinner or weekend lunch. The patties are so flavoursome and also taste really good cold – so make a few more and take this treat for lunch on Monday!
