These smash burger tacos have crispy lace-edged beef, melted American cheese, and all your favorite burger toppings wrapped in a warm tortilla. ♡

The technique is what makes these special. You smash a ball of seasoned beef directly onto a tortilla on a screaming hot griddle. The beef gets paper-thin with crispy, caramelized edges while the tortilla toasts underneath. Add a slice of American cheese while it’s still hot and it melts into every crevice.
Smash, flip, cheese, and dress. Let’s make it together.
Ingredients
Smash Burger Tacos
- 1 lb ground beef (80/20)
- 8 small flour tortillas (street taco size)
- 8 slices American cheese
- 1 cup shredded iceberg lettuce
- 1/2 cup diced white onion
- Dill pickle slices
- Seasoning salt and black pepper to taste
For the special sauce:
- 1/4 cup mayonnaise
- 2 tablespoons ketchup
- 1 tablespoon yellow mustard
- 1 tablespoon pickle relish
Optional add-ins:
- Sliced jalapeños
- Crispy bacon crumbles
- Caramelized onions
How to Make Smash Burger Tacos
- Mix the sauce. Stir together mayonnaise, ketchup, mustard, and pickle relish in a small bowl. Set aside.
- Heat. Get a cast iron skillet or flat griddle screaming hot over high heat. You want it as hot as it goes.
- Smash. Roll beef into 2 oz balls. Place a tortilla on the hot griddle, set a beef ball on one half, and press down hard with a stiff spatula until paper-thin. Season with salt and pepper.
- Sear. Cook without moving for 2 to 3 minutes until the edges are deeply caramelized and lacy. Lay a slice of American cheese on the beef. Fold the empty tortilla half over the cheese side.
- Crisp. Press gently and cook another 30 seconds until the tortilla is golden and toasted on the bottom.
- Dress. Open the taco and add shredded lettuce, diced onion, pickles, and a drizzle of special sauce.
Tips
- Use 80/20 beef. The fat is what gives you crispy, flavorful edges. Leaner beef won’t caramelize the same way.
- Get your pan as hot as possible. This is not the time for medium heat.
- Use a stiff spatula or a burger press and press hard. The harder you smash, the more surface area you get for browning.
- Don’t move the beef once it’s smashed. Let it build a crust before you attempt to flip.
Variations
- Double smash tacos: Use two 1-oz balls per tortilla and stack them for a double patty version.
- Spicy version: Add sliced jalapeños and swap the special sauce for chipotle mayo.
- BBQ smash tacos: Add a smear of BBQ sauce instead of special sauce and top with crispy onion strings.
FAQ
What size tortillas work best for smash burger tacos?
Street taco size flour tortillas (about 4 to 5 inches) are ideal. They’re small enough to fold over the smashed patty without too much extra tortilla. Corn tortillas work too but they tear more easily.
Why is my smash burger taco meat not getting crispy?
Your pan probably isn’t hot enough. Crank it to the highest setting and let it heat for at least 5 minutes. Also make sure you’re pressing hard enough to get the beef paper-thin. Thick patties steam instead of searing.
Can I use a regular pan instead of cast iron?
Cast iron or a flat griddle works best because they hold high heat. A regular nonstick pan won’t get hot enough for a proper sear. Stainless steel can work if you preheat it well.
How do I keep smash burger tacos warm for a crowd?
Keep finished tacos on a sheet pan in a 200°F oven while you work through the batch. They’ll stay warm and the tortilla keeps its crunch. Don’t stack them or they’ll get soggy.
What ground beef ratio is best for smash burgers?
80/20 ground beef is the sweet spot. The 20% fat renders out and creates those crispy, caramelized edges. Anything leaner than 85/15 won’t get the same crust.
