Preheat your oven to 400°F and line a large baking sheet (or use a cast iron skillet) with foil.
Cook the beef in a skillet over medium-high heat, breaking it apart as it browns, about 5–6 minutes. Drain excess fat.
Season the beef by adding all the spices and 2 tbsp of water to the skillet. Stir and cook for another 2 minutes until fragrant. Set aside.
Layer the nachos — spread half the chips on your baking sheet, then add half the beef, half the cheese, half the beans, and half the corn. Repeat with the remaining chips and toppings to build two layers (this ensures every chip gets loaded!).
Top with jalapeño slices and the remaining cheese on top.
Bake for 10–12 minutes, until the cheese is fully melted and the edges of the chips are golden.
Finish with fresh toppings — scatter diced tomatoes, red onion, avocado, and cilantro over the top. Add sour cream, a squeeze of lime, and hot sauce to taste. Serve immediately.
