01 - Preheat your oven to 400°F (200°C) to ensure even cooking and melting of the cheese.
02 - Heat olive oil in a large skillet over medium-high heat. Add the finely chopped yellow onion and cook for 2 to 3 minutes until it begins to soften and become translucent.
03 - Stir in the minced garlic and continue cooking for approximately 30 seconds until its aroma is pronounced, taking care not to burn it.
04 - Introduce the ground beef to the skillet, breaking it apart with a spatula. Cook until the beef is thoroughly browned, which typically takes 5 to 6 minutes. Once cooked, drain any excess fat from the skillet.
05 - Evenly sprinkle the taco seasoning, smoked paprika, cayenne pepper (if desired for extra heat), salt, and black pepper over the browned beef. Mix all ingredients thoroughly, then add 1/4 cup of water. Allow the mixture to simmer for 2 to 3 minutes until the liquid has slightly thickened. Remove the skillet from heat.
06 - On a large baking sheet, arrange half of the sturdy tortilla chips in a single, even layer. Distribute half of the seasoned beef mixture and half of the shredded cheddar and Monterey Jack cheeses over the chips. Repeat this layering process with the remaining chips, beef, and cheeses.
07 - Transfer the baking sheet to the preheated oven and bake for 8 to 10 minutes, or until the cheeses are completely melted and bubbling, indicating they are ready.
08 - Carefully remove the nachos from the oven. Immediately sprinkle with the diced cherry tomatoes, sliced pickled jalapeños, sliced black olives, and finely diced red onion.
09 - Drizzle the sour cream generously over the nachos. Arrange the sliced or cubed avocado, and then sprinkle with the fresh chopped cilantro. Serve these supreme nachos warm with lime wedges on the side for an added zest.
