Bunless Portobello Burger

The Bunless Portobello Burger is a version of a sandwich I made a while ago for my husband. In that version I used grilled chicken instead of ground beef, and I piled on the toppings. We still talk about that sandwich with drool cascading from our mouths. So, in honor of the upcoming 4th of  July weekend, I thought I’d beef that sandwich up a little. With beef.

Honestly, when I have a burger this way, without the bun, I don’t miss the bread. Portobello mushrooms are a wonderful stand-in for bread. They’re savory and satisfying and full of umami.

This is a really filling sandwich. Like gut-bustingly filling. So share with a well-deserving friend. Or save some for leftovers. Or eat it all yourself. You’re the boss. I won’t judge.

I topped mine with mozzarella cheese, bibb lettuce, and tomatoes.  

Onions, avocado, bacon, hot sauce….what will you top yours with?
