01 - Preheat Blackstone griddle or large cast iron skillet over medium-high heat. Lightly oil the surface to prevent sticking.
02 - Divide ground beef into 8 equal balls, approximately 2 oz each for even cooking.
03 - Generously season each beef ball with salt, black pepper, smoked paprika, and garlic powder, ensuring even coating.
04 - Place tortillas on griddle. Top each with shredded cheddar and Monterey Jack blend, covering the center area.
05 - Position seasoned beef ball on cheese mound. Using spatula or burger press, firmly smash beef to spread thinly over melted cheese and tortilla.
06 - Cook for 2-3 minutes until beef develops crispy edges and cheese turns golden and bubbly underneath.
07 - Quickly flip entire taco assembly. Cook tortilla side for 1-2 minutes until crispy and golden brown.
08 - Remove from griddle. Top each taco with lettuce, tomatoes, red onion, jalapeño slices, cilantro, and sour cream.
09 - Plate tacos hot and serve while cheese remains melted and tortilla stays crispy.
