Begin by peeling and dicing your russet potatoes into small cubes, then toss them with olive oil and taco seasoning in a mixing bowl.

Preheat your air fryer to 400°F (200°C). Spread the seasoned potatoes in a single layer in the air fryer basket and cook for 15-20 minutes.

While air frying, heat a skillet over medium heat, add the ground beef, and cook until browned. Drain excess grease, then add water and taco seasoning, simmering for 5-7 minutes.

Once the potatoes are crispy, layer them on plates, followed by the beef mixture and sprinkle with Mexican cheese.

Add your favorite toppings like sour cream, salsa, and chopped veggies for a delicious finish.
