01 - Preheat your oven to 400°F. Line a large baking sheet with aluminum foil or parchment paper for easier cleanup.
02 - In a mixing bowl, toss the shredded chicken with buffalo sauce until every piece is evenly coated.
03 - Spread tortilla chips in an even layer across a large oven-safe platter or baking sheet, overlapping slightly for a sturdy base.
04 - Distribute the buffalo-coated chicken evenly over the tortilla chips, ensuring good coverage from edge to edge.
05 - Sprinkle shredded cheddar and mozzarella cheeses uniformly across the top so every chip gets a portion of both.
06 - Place in the oven and bake for 10–12 minutes, or until the cheese is fully melted and bubbling with golden spots.
07 - Remove from the oven and immediately top with sliced green onions, diced tomatoes, crumbled blue cheese if desired, and jalapeño slices. Drizzle with ranch or blue cheese dressing and serve right away.
