Fried Onion Smash Burger Recipe
Ingredients
- 1 pound (454 g) ground beef
- 2 cloves garlic , minced (or 1/2 teaspoon garlic powder)
- 1 Tablespoon (15 ml) fish sauce or Worcestershire sauce
- 1/2 teaspoon (2.5 ml) ground black pepper , or to personal taste
- salt , to personal taste
- oil for pan frying , optional
- 2-4 slices American cheese , optional
- 2-4 Burger Buns
- Burger Extras pickles, ketchup, mustard, etc…
Instructions
- Slice your onions thin and set them aside.
- In a bowl, combine the 1 pound of beef, minced garlic, 1 Tablespoon fish sauce, and 1/2 teaspoon black pepper (the salt will be added on later while cooking the patties).
- Gently form 4 loosely packed balls but don’t compress the meat too much or else it'll make the burgers more dense.
- Heat skillet or griddle on medium-high heat. If using a leaner meat, lightly oil the pan.
- Lay balls of meat on pan and season with salt and additional pepper if desired.
- Top with generous amount of sliced onions (at least per 1/4 cup each patty, but 1/2 cup or so of the onions/patty is even better).
- Smash the balls of meat to form patties
- Cook the 1st side for about 1-2 minutes or until browned to your liking.
- Making sure the onions stay with the patties, flip the burger patties to onion side down.
- Add the optional slices of cheese on top. Continue to cook until meat is cooked to your preference, usually about another 2-3 minutes (onions should be nice and caramelize – some will be deliciously crispy too.) The cheese should be melted. If you used a slower melting cheese (like some cheddar cheeses), cover the pan with a lid to help trap in heat to melt the cheese.
- Remove the patties from the pan and then toast the open face of the burger buns on the pan for about 1 minute or until toasted to your preference.
- Add burger sauce to the buns, then top with the onion patty. You can add either 1 or 2 patties. Top with the bun and enjoy!
