Smash Burger Tacos (Animal Style)

These smash burger tacos take a standard burger and turn it upside down by smashing crispy beef inside of a golden tortilla. The smashing part is important because more surface area means more flavor! Using the #1 trick this fast food chain uses for every burger, you can enjoy these burgers animal style in just 15 minutes and topped with caramelized onions and In-N-Out special sauce.

Ingredients

  • 4 street style flour tortillas 6"

Beef Pattie

Carmelized Onions

Toppings

Instructions

  • Caramelize the ½ yellow onion low and slow (it'll take about 15 minutes) in 1 tablespoon butter. After about 5 minutes, add the ½ teaspoon brown sugar, ¼ teaspoon salt and pepper, and ½ teaspoon soy sauce and continue to cook until translucent and fragrant.
  • Portion out 1 pound ground beef into 6 balls (each about 2.5 oz). Heat a heavy bottom skillet or flat top grill over high heat. Place a dollop (about 1 teaspoon per burger ball) of yellow mustard on the griddle, then the ground beef ball on top.
  • Smash the ground beef down by placing the tortilla on top and pressing down evenly until the ground beef has spread to the sides of the tortilla. I find it helpful to use a heavy plate or heavy pan to press them down evenly. You can also buy a "smasher" online specifically for this.
    Cook for 1 minute, then smash again to push any grease out to help the burger keep cooking. Cook another 2-3 minutes until browned and crispy, then flip to the tortilla side. Top each with a slice of cheese and cook for 2 more minutes. These are super thin patties, so this is plenty of time to cook them.
  • Remove from the griddle or grill using a metal spatula. You might need to be forceful with scrapping it up if it sticks a bit (which is fine!). Then top with all the good stuff, including the high protein special sauce!

Notes

Tips
  1. Smash twice: After the beef has cooked for 1 minute, smash again to push out any fat to the edges. This fat then continues to cook the smash burger tacos.
  2. Use a metal spatula: The beef can stick a bit to the grill or girddle so a metal spatula helps to scrape any of those little stuck bits up.
  3. Don't grease: We don't want to grease the pan or grill because it prevents that nice and crispy smashed burger from forming.
  4. Press it thin: The beef should be pressed as thin as possible. I've found it helpful to press the tortilla down using a heavy plate or pan so it presses down evenly.
Storage: Leftovers will keep for 3 days in the fridge without the toppings on them. Reheat the burger and tortilla combo in the microwave, in the air fryer, or on the stove top.
Can I use a frozen burger? No, because of the smashing part, you can't use a frozen burger patty.
