If you want to take advantage of the season, then mushrooms are the perfect ingredient for a burger. But to really elevate your burger to heavenly status, Karen will show you how to make green goddess butter. With just a few more ingredients to complement the portobello mushrooms, this is one vegetarian burger to die for.
Ingredients
Method
To make the Green goddess butter, blitz all of the ingredients together in a small food processor. Season and set aside.
Preheat a chargrill pan on the stove on medium-high heat. Grill mushrooms, gill side down, for 8 minutes. Turn, then dollop the cooked side with half of the Green goddess butter and cook for another 2 minutes. Remove from heat and top with parmesan wedges.
Meanwhile, grill ciabatta halves, cut side facing down, for 2 minutes, or until warmed and grill marks appear. Spread with remaining green goddess butter.
To assemble burgers, put mayonnaise and rocket on roll bottoms, arrange mushrooms with cheese on top, then add red onion, chipotle sauce and roll tops. Serve.
