What you will need

This recipe uses 8 simple ingredients that you can find at any grocery store:

  • 1 lb 80/20 ground beef
  • 8 count small flour tortillas
  • 0.5 cup mayonnaise
  • 2 tbsp yellow mustard
  • 1 cup shredded iceberg lettuce
  • 4 slices American cheese
  • 0.5 cup diced white onion
  • 0.25 cup dill pickle slices

Step by step instructions

Step 1: Make the Special Sauce

In a small bowl combine mayonnaise, yellow mustard, and a pinch of garlic powder. Stir until smooth and set aside in the refrigerator.

Step 2: Portion the Beef

Divide the ground beef into 8 equal balls, each about 2 ounces. Season each ball generously with salt and black pepper on all sides.

Step 3: Smash the Beef onto Tortillas

Heat a cast iron skillet over medium-high heat. Place a beef ball onto a tortilla and use a spatula to smash it flat directly onto the dry skillet. Cook for 2 to 3 minutes until the edges are crispy and browned.

Step 4: Add Cheese and Flip

Place a slice of American cheese on the beef, then fold the tortilla over to form a taco shape. Press gently and cook for another 1 minute until the tortilla is golden and the cheese has melted.

Step 5: Assemble and Serve

Open each taco and spread special sauce on the inside. Top with shredded iceberg lettuce, diced white onion, and dill pickle slices. Serve immediately while hot and crispy.

Easy substitutions

Missing an ingredient? Here are some swaps that work perfectly:

  • flour tortillas → corn tortillas for a gluten free option
  • mayonnaise → Greek yogurt for a lighter sauce base
  • American cheese → cheddar cheese slices for a sharper flavor

Common mistakes to avoid

Watch out for these pitfalls that can affect your results:

  • Using lean ground beef which results in dry and less flavorful smash patties
  • Not preheating the skillet enough causing the beef to steam rather than sear
  • Overfilling the taco with toppings which makes it impossible to fold and eat cleanly
