Portabello Mushroom Burger Recipe


I’ve never been a huge fan of burgers that don’t have meat, but a few months ago after my neighbor made me a vegetarian burger made from grilled portabella mushrooms, I became hooked! This recipe is quick & easy and most of all, satisfying.



  • Burger Buns
  • Portabello Mushrooms
  • Green, Yellow or Red Peppers, sliced
  • a little bit of cumin
  • Olive oil
  • 2-3 garlic cloves, minced
  • ground black pepper
  • salt
  • mayonnaise
  • mustard
  • white onion, sliced
  • sliced cheese ( i used havarti)


  1. Heat your grill on medium high heat
  2. Prepare portabella mushrooms by removing the stems and scraping out the black underside with a spoon. You can cut off the overhang with a knife if you would like it to lay flat
  3. In a glass bowl, combine olive oil,  garlic, cumin, pepper and salt and add the mushrooms, spooning the mixture to cover
  4. Allow mushrooms to sit in mixture 15 minutes (or more)
  5. Grill the mushrooms for 10 minutes – if you want cheese burgers add the cheese towards the end so that it melts over the burger
  6. Grill the onions and peppers lightly
  7. While those are grilling, in a separate bowl combine 1/4 c mayo with 2 tbsp mustard, a little pepper and some salt
  8. Add buns to grill
  9. Spoon mayo spread on buns, add mushroom, top with peppers and onions, and serve!
