Three bowls of Air Fryer Neiman Marcus Chicken Casserole topped with crispy crumbs, served with forks, alongside a casserole dish and small bowls of chopped green onions and parsley.

Air Fryer Neiman Marcus Chicken Casserole

Mandy Applegate
Honestly, nothing in my regular rotation beats Air Fryer Neiman Marcus Chicken Casserole when I need something creamy, cheesy, and comforting on a busy night. The filling is packed with shredded chicken, cheddar, caramelized onions, sour cream, and bacon, all topped with a buttery crushed Ritz cracker crust that crisps up beautifully in the air fryer. I make it for weeknight dinners, potlucks, and family get-togethers because it's done fast and always disappears even faster. If you somehow end up with leftovers, store them covered in the fridge for up to 3 days and reheat in the air fryer to get that crust crispy again.

Notes

Here are a few things I've learned from making this casserole that'll help yours come out perfectly every time.
  • Soften the cream cheese fully: Cold cream cheese won't blend smoothly into the filling, so take it out of the fridge at least 30 minutes before you start.
  • Crush the crackers to a medium crumb: You want a mix of fine crumbs and small chunks so the topping has both coverage and texture. A zip-top bag and a rolling pin work perfectly.
  • Don't skip coating the crackers in butter: Every crumb needs to be coated in the melted butter before it goes on top. Dry spots won't crisp up the same way.
  • Watch the topping at the 15-minute mark: Air fryers vary, so start checking early. If the crust is golden but the filling needs more time, loosely cover with foil and cook for the remaining time.
  • Rest before serving: Letting the casserole sit for 5 minutes after cooking helps the filling set slightly so it scoops cleanly and doesn't run all over the plate.
  • Flash freeze for meal prep: If you're freezing individual portions, spread them on a baking sheet and freeze for 1 hour before transferring to a freezer bag or container. They won't stick together, and you can grab exactly what you need.
