Preheat your air fryer to 350°F (175°C).
In a skillet, cook the ground beef over medium heat until browned, breaking it apart with a spoon.
Add the taco seasoning and water to the beef, simmer until thickened, about 5 minutes.
Spread half of the tortilla chips in a single layer on the air fryer basket or tray.
Spread refried beans evenly over the chips.
Sprinkle half of the cooked seasoned beef over the beans.
Top with half of the shredded cheddar and Monterey Jack cheese.
Add pickled jalapeño slices and chopped red onion evenly.
Add the remaining tortilla chips on top and repeat layering with beef, cheese, jalapeños, and onions.
Place the loaded basket in the air fryer and cook for 8-10 minutes, or until the cheese is fully melted and chips are crispy.
Remove from the air fryer carefully and sprinkle chopped fresh cilantro on top.
Serve immediately with optional toppings like sour cream, guacamole, salsa, and pico de gallo.
