Preheat your oven to 350°F (175°C). This will ensure that your nachos bake evenly and the cheese melts perfectly.
In a large skillet over medium heat, add the ground beef. Cook until browned, breaking it apart with a spatula. Drain any excess fat, then stir in your homemade taco seasoning.
On a large sheet pan, spread out the tortilla chips in an even layer. Make sure the chips are overlapping slightly for maximum toppings coverage.
Spread the refried beans over the tortilla chips. Next, evenly distribute the cooked ground beef on top.
Sprinkle the corn, sliced olives, and black beans over the beef. Then, pour the salsa over the entire dish for that zesty flavor.
Generously sprinkle the shredded mild cheddar and jack cheese over the top. Don’t be shy here—the more cheese, the better!
Place the sheet pan in the preheated oven and bake for about 15-20 minutes, or until the cheese is melted and bubbly. Keep an eye on it to prevent burning.
Once baked, remove the nachos from the oven and let them cool slightly. Top with chopped fresh cilantro, dollops of sour cream, sliced jalapeños, and chopped Roma tomatoes for a fresh finish.
