Smash Burger Tacos

Shred the lettuce finely, slice the tomatoes thinly, and cut the red onion into very thin slices. Pat the tomato slices dry on kitchen paper so they do not water down the finished tacos. In a small bowl, stir together the mayonnaise, ketchup, and mustard to make a quick burger sauce, then chill until needed.

Divide the ground beef into 8 equal portions and gently flatten each one onto a tortilla, pressing the meat all the way to the edges in a very thin layer. Season the exposed beef side with salt and black pepper. Pressing the meat onto the tortilla before cooking helps it adhere and creates the signature smash-burger texture.

Heat a large cast-iron pan or flat griddle over high heat until very hot. Add a thin film of oil, then place the tortillas in the pan beef-side down. Press firmly with a spatula for 10 seconds so the meat makes full contact with the surface. Cook until deeply browned and crisp around the edges, about 2 minutes.

Flip each tortilla so the tortilla side is now down. Immediately place a slice of cheese over the hot beef and continue cooking for 30 to 60 seconds until the tortilla is lightly crisp underneath and the cheese starts to soften. Transfer to a tray and repeat with the remaining tortillas, keeping the finished ones loosely tented.

While the tacos are still hot, spread a little burger sauce over the cheesy beef side. Top with shredded lettuce, a slice or two of tomato, a few pickle slices, and a little red onion. Keep the toppings light and evenly distributed so the taco folds cleanly and the crisp tortilla is not weighed down.

If you want extra texture, return the folded tacos to the dry pan for 15 seconds per side to re-crisp the tortilla lightly after topping. This step is optional but effective if the fillings were especially cold. Serve immediately, as the contrast between hot beef and cold toppings is a big part of the appeal.

Arrange on a platter with extra sauce, pickles, and napkins on the side. These are best eaten right away while the beef edge is still crisp and the cheese is molten. For a sharper burger profile, add a few drops of pickle brine or extra mustard inside just before serving.
