These Smashed Big Mac Tacos come together in under 30 minutes and are family-friendly, ultra-crispy, and packed with classic cheeseburger flavor. Ground beef is pressed directly onto flour tortillas and cooked fast in a skillet, then topped with American cheese, pickles, shredded lettuce, and special sauce.
½cupThousand Island dressing (or special sauce)½ cup mayonnaise,2 tablespoons finely chopped dill pickles (or dill relish), 2 teaspoons yellow mustard, and 1 tablespoon ketchup
¼cupvery thinly sliced white or yellow onion
¼teaspoongarlic powder
¼teaspoononion powder
1teaspoonkosher salt
½teaspoonblack pepper
neutral oil for the skillet
optional: sesame seeds
Instructions
Divide the ground chuck into 8 loose portions. Don’t pack them tightly.
Place two portions of raw beef on each tortilla and gently press them into a thin, even layer, spreading close to the edges.
Scatter a small amount of the paper-thin raw onion slices directly over the raw beef, pressing them lightly so they adhere. Season the beef evenly with salt, pepper, and any optional spices.
Heat a large skillet or cast iron pan over medium-high heat and lightly oil the surface.
Place the tortillas beef-side down into the hot skillet. Press firmly with a spatula to smash the beef and onion into the pan. Cook undisturbed for 2–3 minutes, until the beef is deeply browned and the onions soften slightly and release their aroma.
Flip the tacos so the tortilla side is down. Immediately place a slice of american cheese over the beef. Cook another 1–2 minutes, just until the tortilla is lightly crisp and the cheese melts.
Remove from the skillet and assemble immediately. Top with shredded lettuce, sliced pickles, and a generous drizzle of Thousand Island dressing. Sprinkle with sesame seeds if using. Fold and serve hot.

Notes
Cooking Notes:Use a hot skillet so the beef sears and sticks to the tortilla right away, which is key for getting that crisp smash taco texture. Press the beef firmly and evenly into the tortilla so it cooks at the same rate and flips cleanly without tearing.Tips for Best Results:
Heat the skillet until it’s fully hot before adding the tacos so the beef browns instead of steaming.
Press the beef thin and edge-to-edge to create maximum contact and even crisping.
Add the lettuce and pickles after cooking so they stay fresh and don’t wilt from the heat.
Let the tacos rest for a minute after cooking so the cheese melts fully and the beef sets before topping.
How to Know It’s Ready:The beef should be deeply browned and crisp on the tortilla side, with the edges slightly curled. The cheese will be fully melted and glossy, and the tortilla will feel firm when lifted.
