Start by heating olive oil in a pan over medium heat and adding the chicken. Season it with salt and pepper, then cook until it’s fully done and no longer pink. Once cooked, remove and shred the chicken into bite-sized pieces.
Return the shredded chicken to the pan and pour in buffalo sauce and ranch dressing. Stir everything together and let it simmer briefly so the flavors blend well. This step creates that creamy, spicy coating that defines the dish.
Spread tortilla chips evenly on a baking sheet to create a sturdy base. Layer the buffalo chicken mixture over the chips, making sure every bite gets some flavor. Sprinkle shredded cheese generously on top for that perfect melt.
Place the tray in a preheated oven at 400°F (200°C). Bake for about 5–7 minutes until the cheese melts and becomes bubbly. Keep an eye on it to avoid overcooking the chips.
Remove from the oven and garnish with sliced green onions for freshness. You can also drizzle extra ranch or sprinkle blue cheese if you like. Serve immediately while everything is warm and delicious.
