01 - Preheat oven to 400°F (200°C).
02 - Heat olive oil in a skillet over medium heat. Add chopped onion and sauté until soft, about 2–3 minutes. Add minced garlic and cook for 30 seconds.
03 - Add ground beef to the skillet, breaking it apart with a spatula. Cook until browned, about 5–6 minutes. Drain excess fat if necessary.
04 - Stir in cumin, smoked paprika, chili powder, salt, and black pepper. Cook for 1–2 minutes until fragrant, then remove from heat.
05 - Spread half of the tortilla chips evenly across a large baking tray or ovenproof platter. Top with half of the beef mixture, half of the shredded cheeses, and half the jalapeno slices.
06 - Layer the remaining tortilla chips, beef mixture, cheeses, and jalapenos evenly on top.
07 - Place the assembled dish in the preheated oven and bake for 8–10 minutes, or until the cheese is melted and bubbly.
08 - Remove from oven and garnish with sour cream, guacamole, chopped cilantro, diced tomato, and sliced black olives as desired. Serve immediately while hot.
