01 - Heat a large skillet over medium-high heat. Add the ground beef and cook, breaking it apart with a wooden spoon, until browned throughout, about 5–7 minutes. Drain excess fat from the skillet.
02 - Sprinkle the taco seasoning over the cooked beef. Pour in the water and stir thoroughly to combine. Reduce heat to low and simmer for 3–5 minutes until the mixture thickens and the flavors meld. Remove from heat and keep warm.
03 - Set your oven to 400°F to prepare for melting the cheese.
04 - Spread the tortilla chips in a single layer across large baking sheets or oven-safe platters. Avoid overcrowding to ensure even heating.
05 - Distribute the shredded cheddar and Monterey Jack cheeses evenly over the chips, ensuring good coverage for maximum melt.
06 - Place the baking sheets in the preheated oven. Bake for 5–7 minutes, watching closely, until the cheese is fully melted and bubbling.
07 - Transfer the cheesy chips to a serving table or buffet station. Arrange bowls of seasoned beef, nacho cheese sauce, and all prepared toppings nearby so guests can customize their own nachos.
08 - Scatter fresh cilantro over the platter and arrange lime wedges on the side. Let guests build their perfect plate immediately while everything is warm.
