Can I make smash burger tacos ahead of time?
Prepare the toppings and seasoned beef mixture in advance. Cook the tacos fresh on the griddle just before serving; they are best eaten immediately after assembly for optimal crispness.
What size should the beef portions be?
Portion the seasoned beef into small balls about 2–3 ounces each. This size smashes evenly across a corn tortilla when pressed on a hot griddle.
Why do you cook 2 minutes on each side?
The first 2 minutes without moving allows a flavorful crust to form on the beef. The second 2 minutes on the tortilla side crisps the tortilla while cooking the other side of the patty. Adjust time slightly if your griddle runs hotter or cooler.
Can I use flour tortillas instead of corn?
Yes. Flour tortillas will be softer and less crispy; corn tortillas deliver the signature crispy texture this recipe is known for.
What's a substitute for American cheese?
Cheddar, Monterey Jack, or provolone work well. American cheese melts most evenly, but any melting cheese will work.
