Step-by-Step Instructions
1. Make the Burger Sauce
Mix mayo, ketchup, relish, mustard, and hot sauce in a bowl until smooth. Refrigerate until ready to use (up to 3 days ahead).
2. Prepare the Smash Burger Tacos
- Divide beef into 6 equal 2.5 oz balls.
- Top each tortilla with a beef ball. Using a fork or burger press, smash the beef down into a thin layer, leaving a half-inch border. Sprinkle with burger seasoning and salt.
- Heat skillet over medium-high, add a splash of oil. Place 2 tacos meat-side down. Smash firmly with a spatula for ultra-crispy edges. Cook until browned, 2–3 minutes.
- Flip each taco, add a slice of cheese, cook 1 minute more until cheese melts. Repeat with remaining tacos.
3. Assemble and Garnish
- Spoon burger sauce over the cheesy beef. Add lettuce, pickles, onions, tomatoes, jalapeño slices, avocado, and any other fiesta toppings.
- Sprinkle with sesame seeds and chopped cilantro.
4. Serve
- Fold and plate tacos for easy grabbing. Serve with fries, Tex-Mex corn, or fiesta salad for a meal.
- Optional: Create a taco bar with extra toppings for parties and game day.

- Tortilla type affects texture. Small flour tortillas get golden, but corn adds traditional taco flavor.
- Top with homemade “fiesta ranch”: blend ranch dressing, lime juice, and minced jalapeño.
