Let me first start off by saying two very important things 1) these are the BEST burgers I’ve ever made at home and 2) this recipe is directly adapted from my friend and fellow foodie, Mike Puma of @gothamburgersocialclub on Instagram and founder of the “Smash Burger”. I’m s so excited to be sharing his Smash Burger recipe with you all and forever changing your home burger making game!
Okay, so I’ve made a lot of burgers at home so what makes these so good yet so simple? It’s the technique that Mike uses which is to smash thinly sliced onions into the burger which not only gets very crispy caramelized onions but the thin burger patties also get very nicely browned which adds so much flavor! I’m also sharing a very close version of his sauce (because I just can’t help myself but to make things my own!) which absolutely puts a huge cherry on top of this burger recipe.
The key changes I’ve made are:
- Instead of smashing the burgers on the griddle/pan (which requires a heavy spatula or press.. which I didn’t have), I’m smashing them before they hit the pan with the help of some saran wrap and a pan!
- I’m using dairy-free cheese for my recipe because I just live that life whenever possible.. otherwise I recommend using either American cheese slices or Cheddar
- The sauce calls for yellow mustard and pickle juice, but I’ve substituted those for dijon mustard and relish
Okay, let’s get to it…
- 1/2 pound ground sirloin or a high quality ground beef (trust me, it's worth it!)
- 1/2 white onion
- 4 burger buns I suggest a potato or Hawaiian bun
- kosher salt
- 4 slices American or Cheddar cheese For non-dairy, use Violife's aged "cheddar"
- 1 1/2 tablespoons ketchup
- 1/4 cup Hellmann's mayonnaise
- 1 tablespoon dijon mustard
- 2 tablespoons relish
- 1/4 teaspoon dark brown sugar
- 1 pinch paprika
- 1 pinch garlic powder
Mix all ingredients together until well combined and set aside.
Divide your ground sirloin into 4 even parts and roll into balls. Set aside.
Slice your onion VERY thin. If you have a mandolin slicer use this on the thinnest setting. If not, practice your chef skills and use your sharpest knife to carefully slice your onion as thin as possible--the thinner the better for this recipe!
Place a large non-stick saute pan or cast iron (or if you have a griddle, use that!) on HIGH heat. Turn on your vent fan if you have one, otherwise, try to open a window if possible. There will be some smoke during cooking.
Cut two pieces of saran wrap (or parchment paper) each about 1 foot long. Place one piece on a flat surface, add one ball of the ground sirloin and top with about 1/4 of the thinly sliced onions. Now place the other piece of saran wrap on top and using a small pan (a small cutting board or flat plate will also work here), smash the burger until it is 1/4 inch thick. Repeat this process for the remaining 3 burgers.
Optional: if you prefer your buns toasted, then add some spreadable butter or cooking spray to each side and place down on your pan for just a few seconds until they begin to brown. Remove and set aside.
Cooking time! Add the burger patties to your pan with the onion side up first. Season the top with kosher salt and cook for about 1 min and 30 seconds, flip, add the cheese, cover and cook for another 1 min and 30 seconds.
Remove the patties and place on your burger buns. I recommend waiting a 1-2 minutes to let the juices from the burger seal before enjoying!
