Neiman Marcus Chicken Casserole

Mandy Applegate
I love making Neiman Marcus Chicken Casserole when I need a dinner that feels truly special and feeds a hungry crowd without a lot of stress. The filling is thick and creamy with shredded chicken, cream cheese, sour cream, sharp cheddar, caramelized onions, and crispy bacon all baked together beautifully, and the buttery Ritz cracker topping comes out golden and crunchy in the most irresistible way. I make it for Thanksgiving, Christmas, Easter, potlucks, and family dinners because it always impresses everyone at the table. Store leftovers covered in the fridge for up to 4 days and reheat in the oven to keep that cracker topping golden and crispy.

Notes

Here are a few things I've learned from making Neiman Marcus Chicken Casserole that'll help you get the best results every time.
Soften the cream cheese fully: Pull the cream cheese out of the fridge at least 30 minutes before you start mixing. Cold cream cheese won't blend smoothly, and you'll end up with lumps in the filling.
Use rotisserie chicken to save time: Shredded rotisserie chicken works perfectly here and cuts down your prep significantly. Just pull it apart by hand, and it'll fold right into the creamy base without any extra cooking.
Caramelize the onions low and slow: Don't rush the caramelized onions if you're making them from scratch. Cooking them over low heat for 30 to 40 minutes brings out the deep, sweet flavor that gives this casserole its signature richness.
Crush the Ritz crackers coarsely: Aim for a rough, uneven crumble rather than fine crumbs. A chunkier topping bakes up with more texture and gives you that satisfying crunch on top.
Check for doneness at 25 minutes: Ovens vary, so start checking the casserole at the 25-minute mark. You're looking for a golden top and bubbling edges. Pull it out as soon as it hits that point to avoid drying out the filling.
Store properly: Once cooled, cover the dish tightly or transfer the portions to airtight containers. Refrigerate for 3 to 4 days or freeze for up to 2 months. If frozen, thaw overnight in the fridge, and reheat in the microwave or oven until warmed through and the topping crisps back up.
