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 piled on the toppings. We still talk about that sandwich with drool cascading from our mouths. So, this upcoming weekend, I thought I’d beef that sandwich up a little.
Honestly, I don’t miss the bread when I have a burger this way without the bun. Portobello mushrooms are an excellent stand-in for bread. They’re savoury and satisfying and full of umami.
This is a filling sandwich like gut-busting 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. You can assemble this bunless portobello burger any way you like it.
