This sandwich can be made in 10 minutes, 20 if you want caramelized onions.

Ingredients (serves 2):

  • 2 hamburger buns
  • 2-4 slices butter lettuce or 1/4 cup arugula
  • 2 slices blue cheese
  • 2 large portobello mushrooms
  • 1 medium yellow onion
  • 2 tablespoons balsamic vinegar
  • 2 tablespoons olive oil
  • 1/3 cup water or stock (chicken or veggie)
  • 2 tablespoons butter
  • 2 tablespoons mayo
  • 2 cloves of garlic, minced
  • 1 dash of paprika
  • 1 pinch salt, 1 pinch pepper

Caramelized Onion:

I find that onions caramelized faster when cooked in a smaller rather than larger pot, although the process will still require some patience.  Slice raw onion to desired thickness.  In a small pot, melt the butter on low heat.  Add onions and stir occasionally with a spoon, cooking for about 20 minutes on low heat or until the onions have turned translucent and brown.

Toast the buns at 400 degrees F for 5 minutes.

Preparing the Portobello mushroom “patty”:

Clean the mushroom with a paper towel dampened with water.  Taking a spoon, scrap the gills off like below.  The gills tend to give the mushroom a woody flavor and we want to avoid that here.  With a pair of kitchen shears, cut the outer edges of the mushroom off to make the patty as flat and even as possible for cooking.

Heat a medium saute pan on medium to high heat. ¬†Add olive oil. ¬†Put the mushroom in the pan, top side down. ¬†Add olive oil and balsamic vinegar on top. ¬†Sprinkle on salt and pepper or any other dry seasons you’d like. ¬†Add a splash of water or stock to steam the pan. ¬†Cover with a lid and cook for about 3 minutes, flipping the mushrooms over and re-seasoning with balsamic vinegar, salt, and pepper for another 2-3 minutes. ¬†Flip the mushrooms again so that the top side is down. ¬†Put a slice of blue cheese on each patty, cover, and let melt for 1-2 minutes. ¬†Remove patties from the pan.

Garlic Chili Mayo:

In a small bowl, mix the mayo with raw minced garlic and paprika or cayenne powder to taste.

Now it’s time to assemble the sandwich. ¬†Spread the mayo sauce on the toasted buns. Pile on the mushroom patty with cheese, caramelized onion, and butter lettuce or arugula. ¬†That’s it!
