Homemade Shake Shack Two Ways
Have you heard of Shake Shack? In some ways, I would lightly call it the “In-N-Out” of New York City based on its popularity with tourists. My husband is obsessed, and was one of the first in line when they opened their Boston location. In my opinion, the regular burger at Shake Shack is overpriced and nothing to write home about. However, the Shroom Burger or the Shack Stack are worth the hype. If you have never had the privilege of indulging here while in NYC, then allow me to describe it. The Shroom Burger is two Portobello mushroom caps that have been lightly scooped out to accommodate a generous cheese filling. They are pressed together, lightly coated and then deep-fried. The result is a deliciously unhealthy, cheesy and hearty vegetarian mushroom patty. To create the Shack Stack, this monster patty is layered on top of a normal beef burger and served on a grilled potato roll. To say that this is over the top is an understatement, but more than just my husband is obsessed as evidenced by the around-the-block lines that Shake Shack draws daily.
Since we are moving out of Boston, my husband and I wanted to create a homemade version of his favorite burger. We each had our own idea of how to do this. A Shake Shack purist, his mission was to recreate as close to an exact replica as possible – double mushroom patty with a gooey cheese filling over a beef patty. I wanted to come up with a less intense version that is not quite as indulgent so that we can enjoy this treat more often at upcoming summer BBQs. In my opinion, both avenues were a messy success. Our method still needs perfecting and will never quite replicate the real deal, but for a homemade option we are quite happy!
Neither of the following are recipes, more like ingredient lists and bare bones guidelines of what we did (with pictures). If you have or plan to experiment with this chain favorite, let us know what you did that worked (or didn’t!)
Classic “Shack Stack”
Take two medium-sized Portobello mushroom caps and wash well. Gently scrape out the middle of the mushroom (what we call “gills”). Place mushroom caps between two paper towels and two microwave safe dishes. Microwave for 1.5-3 minutes, or until moisture seeps out and the mushroom caps become flat and pancake-like. Allow to cool. Mix together shredded cheese (we used Muenster and Cheddar). Form a palm sized ball of cheese. Place the cheese in the center of the mushroom caps. Surround with plastic wrap and wrap tightly to adhere the two mushroom caps together.
Allow to sit for several minutes. In separate bowls, lay out flour, a beaten egg, and plain panko bread crumbs. Dip the mushroom patty in flour, then egg, then breadcrumbs, then repeat in egg and breadcrumbs.
Deep fry in canola oil until the outside is golden brown. Meanwhile, cook a burger as desired. Toast a potato roll lightly. Assemble burger with mushroom patty, lettuce, tomato and onion. Serve immediately.
Lightened Up “Shack Stack”
Wash and prepare one mushroom patty as above. Follow instructions to flatten the mushroom cap. Mix together one to two tablespoons of shredded cheese and place in the middle of the mushroom cap. Create a covering for the cheese with either 1/4 lb ground beef mixture or a pre-formed hamburger patty.
Grill beef side down first until meat is cooked as desired, then flip for one minute to melt cheese.
Serve on toasted potato roll with lettuce, onion and tomato.
