Smash Burger Tacos
Ground beef smashed directly onto a flour tortilla in a screaming hot skillet — the beef fat fries the tortilla from underneath as the patty gets its crust on top. Flipped once, topped with American cheese, special sauce, shredded lettuce, diced onion, and pickles. Ready in 15 minutes.
Ingredients
Meat & Protein
- 1 lb ground beef 80/20 — do not use lean beef
Produce
- 1 white onion finely diced, for topping
- 1.5 cups iceberg lettuce finely shredded, for topping
Dairy
- 4 American cheese slices
Pantry & Canned Goods
- 4 flour tortillas small, or hard taco shells
- ¼ cup dill pickles thinly sliced
- ¼ cup mayonnaise Hellmanns or Dukes recommended
- 2 tbsp ketchup
- 1 tbsp yellow mustard
- 1 tbsp dill pickles finely minced — for the special sauce
Seasonings & Spices
- ½ tsp kosher salt
- ½ tsp black pepper
- ½ tsp garlic powder
- ¼ tsp smoked paprika
Instructions
- Make the special sauce: stir together the mayonnaise, ketchup, yellow mustard, and minced pickle in a small bowl until combined. Refrigerate until serving. This takes 2 minutes and is worth the effort over plain ketchup.
- Divide the ground beef into 4 equal portions — about 4 oz each. Loosely roll each portion into a ball. Do not compact them tightly; a loosely formed ball smashes more evenly. Season each ball with the kosher salt, black pepper, garlic powder, and smoked paprika.
- Heat a large cast iron skillet over high heat for 2 to 3 minutes until very hot — you want it as hot as it will get on your stovetop. No oil needed; the beef fat does the work.
- Place one beef ball directly in the hot skillet. Immediately lay a flour tortilla on top of the beef. Using a heavy spatula, burger press, or the flat bottom of a small cast iron pan, press down hard and firmly to smash the beef flat — as thin as you can get it, roughly the size of the tortilla. The beef fat will immediately start frying the tortilla from underneath.
- Cook for 2 to 3 minutes without moving — let the crust develop fully on the beef side. The tortilla on top will be getting toasted and crisped by the steam and fat from below. You'll see the edges of the beef browning and crisping.
- Flip the whole thing — beef side up, crispy tortilla side down — using a wide spatula. Immediately place an American cheese slice on the beef. The residual heat will melt it in about 60 seconds. Cook for 1 minute more until the tortilla bottom is golden and crisped through. Remove to a plate. Work in batches, one or two at a time depending on pan size.
- Top each taco with special sauce, shredded iceberg lettuce, finely diced white onion, and sliced pickles. Fold and eat immediately — these do not hold well once assembled.
Notes
80/20 ground beef only. The fat is what fries the tortilla from underneath as the beef cooks — leaner beef won't produce enough fat to crisp the tortilla properly and the bottom will stay soft.
The cast iron needs to be very hot before the beef goes in. Test it with a drop of water — it should evaporate on contact immediately. A hot pan is what creates the dark, crispy crust on the beef. A warm pan just steams the meat gray.
Smash hard and fast. You have about 10 seconds after the beef hits the pan before it starts to set — that's your window to get it flat. Use your body weight behind the spatula if needed. The thinner the patty, the better the crust-to-meat ratio.
These need to be assembled and eaten right away. The tortilla will soften as it sits with the toppings on it. Cook in batches and top as you go rather than cooking everything first.
A Blackstone griddle or flat-top makes this easier at scale — you can cook all four at once. A cast iron skillet works perfectly for one or two at a time on the stovetop.
