Start by marinating your choice of steak for the carne asada. Common options include flank, skirt, or sirloin steak. Use your favorite marinade or a simple mix of lime juice, garlic, cumin, and salt. Let it marinate for at least 30 minutes, or up to overnight for maximum flavor.
Heat a grill or skillet over medium-high heat. Once hot, add the marinated steak and cook for about 5-7 minutes on each side, or until it reaches your desired doneness. Remove from heat and let it rest for a few minutes before slicing it thinly against the grain.
Preheat your oven to 350°F (175°C). This will ensure that your nachos bake evenly and the cheese melts beautifully.
On a large baking sheet, spread out an even layer of tortilla chips. Top with the sliced carne asada, followed by a generous sprinkle of shredded cheddar cheese.
Place the assembled nachos in the preheated oven and bake for about 10-15 minutes, or until the cheese is melted and bubbly. Keep an eye on them to prevent burning!
Once out of the oven, add your fresh toppings: scatter the diced Roma tomato, chopped red onion, sliced jalapeños, and diced avocado over the cheesy nachos. Top it off with dollops of guacamole and sour cream.
Finish with a sprinkle of fresh cilantro for a pop of color and flavor. Serve your Easy Carne Asada Nachos hot, with extra guacamole and sour cream on the side for dipping!
