01 - Set the oven to 400°F to warm up.
02 - Heat olive oil in a skillet over medium heat. Add the onion and cook until softened, about 2 to 3 minutes. Stir in minced garlic and cook an additional 30 seconds.
03 - Add ground beef to the skillet, breaking it apart with a spatula. Cook until browned, approximately 5 to 6 minutes, then drain any excess fat if needed.
04 - Incorporate cumin, smoked paprika, chili powder, salt, and black pepper into the beef mixture. Cook for 1 to 2 minutes until aromatic, then remove from heat.
05 - Spread half of the tortilla chips evenly on a large ovenproof baking tray. Top with half of the beef mixture, half the shredded cheeses, and half the jalapeno slices.
06 - Add the remaining tortilla chips, followed by the rest of the beef, cheeses, and jalapenos, creating a second layer.
07 - Place the tray in the preheated oven and bake for 8 to 10 minutes until the cheese melts and becomes bubbly.
08 - Remove from oven and garnish with sour cream, guacamole, cilantro, diced tomato, and black olives as desired. Serve immediately while hot.
