This Neiman Marcus chicken casserole is the recipe that became the single most popular new recipe of 2025 — and after one bite you will understand with complete certainty why millions of people made it this year. Tender shredded chicken in a rich creamy cheddar and sour cream sauce with a hint of toasted almond crunch throughout, all topped with a generous golden buttery Ritz cracker crust that bakes into the most incredible crunch imaginable. I have been making this Neiman Marcus chicken casserole at Golden Recipes since it exploded in popularity and it has become the most consistently requested recipe in my kitchen without question. It is simultaneously elegant and comforting, impressive and effortless, rich and satisfying — and it takes about 12 minutes of actual prep before the oven handles everything else. The name comes from the famous Neiman Marcus department store known for its legendary food — and this casserole absolutely lives up to that prestigious association.
Why You’ll Love This Neiman Marcus Chicken Casserole
The toasted slivered almonds inside the creamy filling are the element that makes this casserole so completely distinctive from every other chicken casserole you have ever made. They add a delicate nutty crunch that you encounter in every few bites — a textural surprise that makes the dish feel genuinely special and sophisticated rather than just another cream-based chicken casserole. Toasting them first in butter deepens their flavor into something rich and warm that complements the creamy cheddar sauce in the most beautiful way.
The combination of mayonnaise and sour cream in the sauce is what makes the filling so uniquely rich and creamy. Mayonnaise adds body and a subtle savory richness that cream of chicken soup alone cannot replicate — it creates a sauce that is thick and luxurious and coats every piece of chicken in the most satisfying way. Combined with the sharp cheddar and that buttery golden Ritz cracker crust on top this Neiman Marcus chicken casserole is genuinely one of the most crowd-pleasing recipes ever created. Million Dollar Chicken Casserole and our Cheesy Ritz Chicken are equally incredible if you love this style of creamy chicken dinner.
Equipment You’ll Need
- 9×13 inch baking dish
- Large mixing bowl
- Small skillet for toasting almonds
- Small bowl for the cracker topping
- Measuring cups and spoons
- Electric hand mixer
Ingredients
- 4 cups cooked shredded chicken — rotisserie is perfect
- 1 cup mayonnaise
- 1 cup sour cream
- 1 can (10.5 oz) cream of chicken soup — undiluted
- 2 cups freshly shredded sharp cheddar cheese — divided
- ¾ cup slivered almonds, toasted in 1 tbsp butter
- 3 green onions, thinly sliced
- 1 teaspoon garlic powder
- ½ teaspoon onion powder
- Salt and black pepper to taste
For the Ritz Cracker Topping
- 1½ sleeves Ritz crackers, finely crushed — about 2 cups
- 4 tablespoons butter, melted
- ¼ cup freshly grated Parmesan
- ½ teaspoon garlic powder
Substitutions
Greek yogurt can replace sour cream for extra protein and a slightly tangier result. Pecans or walnuts can replace slivered almonds for a different nutty crunch. For a nut-free version simply omit the almonds entirely — the casserole is equally delicious without them. Cream of mushroom soup can replace cream of chicken for a slightly earthier flavor. For extra richness add 4 oz of softened cream cheese to the mayonnaise and sour cream mixture. Crushed Townhouse crackers or Ritz Bits work equally well if you cannot find regular Ritz. Add 1 cup of blanched broccoli florets to the filling for a broccoli version.
How to Make Neiman Marcus Chicken Casserole
Toast the Almonds
Preheat your oven to 350°F (175°C) and grease your 9×13 baking dish. In a small skillet melt 1 tablespoon of butter over medium heat. Add the slivered almonds and cook for 3 to 4 minutes stirring constantly until they are golden and deeply fragrant — watch them carefully as they go from perfect to burnt in about 30 seconds. Transfer immediately to a plate to cool. This toasting step is essential — raw almonds lack the rich buttery depth that makes them so special in this casserole.
Make the Creamy Filling
In a large mixing bowl combine the mayonnaise, sour cream, and undiluted cream of chicken soup. Stir until completely smooth and unified. Add the garlic powder, onion powder, salt, and pepper. Stir in 1½ cups of the shredded cheddar until incorporated. Add the shredded chicken, toasted slivered almonds, and sliced green onions. Fold gently but thoroughly until every piece of chicken is fully coated in the creamy cheddar sauce and the almonds and green onions are evenly distributed. Taste the mixture — it should be creamy, savory, slightly tangy from the sour cream, and well seasoned.
Assemble
Spread the entire creamy chicken mixture evenly into your prepared baking dish — use a spatula to push it into the corners and create a smooth flat surface. Scatter the remaining ½ cup of cheddar across the top of the filling.
Make and Add the Ritz Topping
In a small bowl combine the crushed Ritz crackers, melted butter, Parmesan, and garlic powder. Stir until every cracker crumb is coated in butter and the mixture looks golden and slightly clumped. Scatter the cracker topping evenly and generously across the entire top of the casserole — cover every inch for maximum crunch in every serving.
Bake
Place uncovered in the preheated oven and bake for 35 to 40 minutes until the Ritz topping is deeply golden brown, the filling is bubbling at the edges, and the casserole is hot all the way through. Rest 5 minutes before serving. The topping should look spectacular — golden and buttery and completely inviting.
Variations
- Broccoli Neiman Marcus — fold 2 cups of blanched broccoli florets into the filling for a broccoli chicken version
- Bacon loaded — stir 1 cup of crumbled cooked bacon into the filling for smoky richness
- Pecan version — replace slivered almonds with toasted pecans for a more Southern-inspired nutty flavor
- Ranch version — add 1 packet of dry ranch seasoning to the filling instead of garlic and onion powder
- Four cheese — add cream cheese to the filling and use a combination of cheddar mozzarella and Parmesan for extra cheese complexity
What to Serve With It
This Neiman Marcus chicken casserole is an elegant and complete dinner on its own. Steamed green beans or roasted asparagus on the side complement the rich creamy filling beautifully. A simple green salad with lemon vinaigrette cuts through the richness perfectly. Warm dinner rolls are perfect for scooping up any extra sauce from the pan. For a complete special occasion dinner serve alongside our Cheesy Scalloped Potatoes — two incredibly indulgent dishes that together create the most impressive home-cooked dinner spread imaginable.
Pro Tips
- Always toast the almonds — raw almonds taste flat and starchy, toasted almonds are rich buttery and deeply flavored
- Use undiluted cream of chicken soup — this is what creates the proper thick body of the filling
- Always bake uncovered — the Ritz topping must have direct heat to get golden and crispy
- Rest 5 minutes before serving — the creamy filling sets slightly for cleaner portions
- Always shred your own cheddar — block cheese melts far more smoothly into the filling
Common Mistakes
- Skipping the almond toasting — raw almonds add no flavor depth to the casserole
- Covering while baking — the cracker topping steams and becomes soggy
- Diluting the cream of chicken soup — use it straight from the can
- Pre-shredded cheese — never melts as smoothly into the creamy filling
- Not resting before serving — filling runs if cut immediately
Storage and Reheating
Store covered in the fridge for up to 4 days. To reheat and restore the cracker topping crunch place on a baking sheet and bake uncovered at 375°F for 12 to 15 minutes. Microwave works on medium power but the topping softens. Freeze assembled before baking without the cracker topping for up to 2 months — add the topping fresh and bake from frozen at 350°F covered for 30 minutes then uncovered for 20 more minutes.
