Preheat the oven to 400°F. Line a large sheet pan with parchment paper or apply a light coat of cooking spray to prevent sticking and facilitate cleanup.
02 -
Heat olive oil in a large skillet over medium-high heat. Add diced onion and cook until translucent, approximately 3 minutes. Stir in minced garlic and cook for an additional 30 seconds until fragrant. Add ground beef, breaking it apart with a wooden spoon, and cook until fully browned, about 6 to 7 minutes. Drain excess fat if needed.
03 -
Sprinkle taco seasoning over the cooked beef. Add 1/4 cup water, stir thoroughly, and simmer for 2 to 3 minutes until most of the liquid is absorbed and the seasoning coats the meat evenly. Remove from heat and set aside.
04 -
Spread tortilla chips evenly in a single slightly overlapping layer on the prepared sheet pan. Avoid piling to ensure uniform topping distribution and crispiness.
05 -
Distribute the seasoned meat evenly over the chips. Evenly scatter black beans, diced green chilies, and corn kernels across the base.
06 -
Evenly cover the toppings with shredded cheese, extending to the edges. Arrange halved cherry tomatoes, jalapeño slices, and optional black olives atop the cheese layer.
07 -
Bake in the preheated oven for 7 to 10 minutes, monitoring closely after 7 minutes to achieve melted, bubbling cheese and lightly browned chip edges without burning.
08 -
Remove the sheet pan from the oven. Immediately garnish with chopped fresh cilantro and sliced green onions. Serve hot accompanied by sour cream, guacamole, and lime wedges.
