Bob Hart’s Mushroom Burger with Smoked Chili BBQ Recipe

Food-writer, broadcaster and founder of the Australian Barbecue Academy, Bob Hart, shares his unique Mushroom Burger with Smoked Chili recipe with us.

The very idea of vegetarians rolling up to a barbecue causes great mirth in certain circles. But not in this one. Because many vegetables, and a couple of magical vegetarian dishes, make outstanding barbecue fare, even for carnivores.


  • portabello mushrooms
  • ciabatta rolls
  • butter
  • lemon juice
  • parsley
  • garlic
  • dijon mustard
  • mayonnaise
  • sour cream
  • chipped chipotle peppers in adobo
  • salad onion
  • parmesan cheese
  • salt & pepper


Oil and season a large, portobello (flat) mushroom per person and split a ciabatta roll for each mushie.

Place the mushies, gill sides down, on a hot charcoal grill.

Flip after a few minutes, and top each mushroom with a disc of herb butter made with butter, lemon juice, parsley, garlic and dijon mustard.

Place both sides of each roll, cut sides down, on the grill for a minute, and remove.

Spread with chipotle mayo (bottled mayo, sour cream and chipped chipotle peppers in adobo), top each with a mushroom and a few thin discs of salad onion. Top with grated parmesan cheese and close the burger. Eat.
