01 - Preheat your Blackstone griddle or large cast iron skillet over medium-high heat. Lightly oil the surface with vegetable oil or melted butter.
02 - Divide the ground beef into 8 equal balls, approximately 2 oz each.
03 - Season each beef ball evenly with salt, black pepper, smoked paprika, and garlic powder.
04 - Place each tortilla on the hot griddle. Immediately top with a generous mound of shredded cheddar and Monterey Jack cheese blend, covering the center of the tortilla.
05 - Place a seasoned beef ball directly on top of the cheese mound. Using a sturdy metal spatula or burger press, smash the beef firmly downward to spread it thinly over the melting cheese and tortilla.
06 - Cook for 2-3 minutes until the beef develops crispy edges and the cheese becomes golden and bubbly beneath.
07 - Flip the entire taco assembly quickly so the tortilla side makes direct contact with the griddle. Cook for an additional 1-2 minutes until the tortilla is crispy.
08 - Remove from heat and transfer to a serving platter. Immediately top each taco with lettuce, diced tomatoes, red onion, jalapeño slices, fresh cilantro, and a dollop of sour cream.
