Essential Ingredients for a Gourmet Casserole
Creating a Neiman Marcus Chicken Casserole requires high-quality staples. Here is what you need to gather for your mise en place.
Poached Chicken Breast: You will need 1.5 lbs (680g) of chicken. Poaching in aromatics ensures the meat is infused with flavor before it even hits the baking dish. If you’re in a rush, you could use leftovers from a perfectly grilled chicken, but poaching is the traditional method for that signature “Neiman’s” silkiness.
Fresh Broccoli Florets: Use 3 cups (approx. 250g) of fresh broccoli. Steaming them separately allows you to control the “snap”—no mushy vegetables allowed in this premium bake!
Thick White Cream Sauce: This is a classic Béchamel fortified with heavy cream. You will need 4 tbsp (56g) of butter, 1/4 cup (30g) of all-purpose flour, 1.5 cups (360ml) of whole milk, and 1/2 cup (120ml) of heavy cream. This forms the velvety bond for the Neiman Marcus Chicken Casserole.
The Cheese Duo: 1.5 cups (170g) of shredded mozzarella provides the “pull,” while 1/2 cup (50g) of freshly grated parmesan adds the toasted golden-brown spots we crave. This duo is much more complex than the flavors found in a standard cheesy chicken pasta casserole.
Fresh Parsley: A heavy garnish of finely chopped fresh green parsley isn’t just for looks; it cuts through the richness of the cream and cheese.
Step-by-Step Instructions for the Perfect Bake
Step 1: The Precision Poach
Place your chicken breasts in a large pot. Cover with water or chicken broth by 1 inch (2.5cm). Add a pinch of salt and a few peppercorns. Bring to a gentle simmer—never a rolling boil. Simmer for 12-15 minutes until the internal temperature reaches 165°F (74°C). Once cooled, cut into bite-sized poached chicken breast chunks.
Step 2: Steaming the Greens
While the chicken poaches, place your broccoli florets in a steamer basket over boiling water. Steam for exactly 4-5 minutes. They should be “fork-tender” but still possess a vibrant, bright green hue. This ensures they don’t disappear into the Neiman Marcus Chicken Casserole sauce.

Step 3: Crafting the Velvety White Sauce
In a heavy-bottomed saucepan, melt the butter over medium heat. Whisk in the flour and cook for 2 minutes to remove the raw flour taste. Slowly drizzle in the milk and cream, whisking constantly to prevent lumps. Continue cooking until the sauce is thick and velvety, coating the back of a spoon. Season generously with salt and white pepper.
Step 4: Assembly and The Golden Crust
Preheat your oven to 375°F (190°C). In a white rectangular ceramic baking dish, combine the poached chicken chunks and steamed broccoli. Pour the thick white cream sauce over the top, folding gently to ensure every piece is coated.
Top with the dense layer of mozzarella followed by the parmesan. Bake for 20-25 minutes. For the final 2 minutes, you can turn on the broiler to achieve those deep golden-brown toasted spots. If you love this texture, you’ll also enjoy the topping on our chicken cordon bleu casserole.
Expert Tips for Casserole Success
- Don’t Overcook the Broccoli: Remember that the broccoli will continue to cook in the oven. Under-steam it slightly to keep that perfect texture.
- Room Temperature Dairy: Using room temperature milk and cream for your sauce prevents the roux from “shocking” and creates a smoother emulsion.
- Freshly Grated Cheese: Avoid pre-shredded bags! Pre-shredded cheese is coated in potato starch, which prevents it from melting into that bubbly mozzarella texture we want.
- Rest Before Serving: Let the Neiman Marcus Chicken Casserole sit for 5-10 minutes after exiting the oven. This allows the sauce to set so it doesn’t run all over the plate.
Storage, Reheating, and Freezing
Storage: Keep leftovers in an airtight container in the refrigerator for up to 3 days. The flavors actually deepen overnight!
Reheating: To maintain the velvety white cream sauce, reheat in the oven at 350°F (175°C) covered with foil. If using a microwave, add a splash of milk to prevent the sauce from breaking.
Freezing: This casserole freezes well. Assemble the dish but do not bake it. Wrap tightly in plastic wrap and foil. Freeze for up to 2 months. Thaw in the fridge overnight before baking as directed.
What to Serve With This Classic Dish
Since this Neiman Marcus Chicken Casserole is quite rich, it pairs beautifully with a crisp apple walnut salad to provide acidity. If you want a heartier meal, serve it alongside a side of smoked gouda mac and cheese for a truly indulgent feast.
Frequently Asked Questions
Absolutely. You can assemble the entire dish, cover it with plastic wrap, and store it in the fridge for up to 24 hours before baking. Just add 5-10 minutes to the baking time if cooking straight from the fridge.
Yes, you can substitute rotisserie chicken if you’re short on time. However, poaching the chicken at home ensures a more tender, succulent texture that better mimics the original Neiman Marcus style.
The secret is to slightly under-steam the broccoli florets (about 4 minutes) before adding them to the casserole. They will finish cooking to a perfect fork-tender state in the oven.
A combination of high-moisture mozzarella for the ‘pull’ and freshly grated parmesan for the golden-brown toasted spots yields the best visual and flavor results.
If the sauce is thin, the roux may not have cooked long enough before adding liquid, or the ratio of liquid to flour was off. Ensure you whisk until the sauce coats the back of a spoon before assembling.
