Quick Stats
Why This Neiman Marcus Chicken Casserole Works
A True Potluck Classic: This casserole became legendary in the 1980s, supposedly tracing back to the restaurant inside the Neiman Marcus department store. Whether or not the story is true, it spread across America as a creamy, crunchy, crowd-pleasing potluck staple. If you enjoy that retro angle, our look at department store restaurants is a fun read.
Smart Ingredient Swaps: The original leaned on canned cream of chicken soup, sour cream, and a Ritz cracker topping. This version uses a homemade cream sauce, Greek yogurt, and an almond-flour Parmesan topping instead, which is how it lands at 6g net carbs while keeping the same creamy, cheesy character.
Protein-Packed and Filling: Lean chicken breast anchors the dish with 28 grams of protein per serving, so it eats like a real, satisfying main rather than a light side. That protein plus the lower carb count is what makes it a blood-sugar-conscious comfort food.
Greek Yogurt Upgrade: Swapping sour cream for Greek yogurt adds protein and a pleasant tang without much extra fat, and it holds up beautifully in the creamy base. For another creamy keto chicken bake, see our low-carb chicken pot pie.
Made for Make-Ahead: It assembles in advance, bakes from cold, and freezes well, which makes it one of the easiest comfort dinners to keep on standby.

Neiman Marcus Chicken Casserole | Keto & Diabetic-Friendly
Ingredients
Equipment
Method
- Preheat your oven to 350°F (175°C). Lightly spray a 9×13 inch baking dish with cooking spray and set aside.
- Make the homemade cream base: In a medium saucepan over medium heat, melt 2 tablespoons butter. Whisk in 2 tablespoons almond flour and cook for 1 minute, stirring constantly.
- Gradually whisk in the almond milk and chicken broth, continuing to whisk until smooth. Bring to a gentle simmer and cook for 3-4 minutes until thickened, stirring frequently. Remove from heat and let cool slightly.
- In a large mixing bowl, combine the diced chicken, steamed broccoli, Greek yogurt, 1/2 cup of the shredded cheddar cheese, garlic powder, onion powder, black pepper, and salt.
- Pour the homemade cream sauce over the chicken mixture and stir until everything is well combined and evenly coated.
- Spread the mixture evenly into your prepared baking dish. Sprinkle the remaining 1/4 cup cheddar cheese over the top.
- Prepare the crunchy topping: In a small bowl, combine 3/4 cup almond flour, Parmesan cheese, melted butter, and dried parsley if using. Stir until the mixture resembles coarse crumbs.
- Sprinkle the almond flour topping evenly over the casserole, distributing it loosely without pressing down.
- Bake uncovered for 30-35 minutes, until the casserole is bubbly around the edges and the topping is golden brown.
- Remove from the oven and let rest for 5-10 minutes before serving. This allows the filling to set slightly for easier serving.

Chef Tips for Perfect Results
Use Rotisserie Chicken: A store-bought rotisserie chicken is the fastest shortcut. Pull the skin before shredding to keep the fat in check, and you will need about one medium bird for this casserole.
Cook Chicken to 165°F: If you are cooking the chicken from raw, bring it to an internal temperature of 165°F and let it rest before shredding so it stays juicy in the bake.
Toast the Almond-Flour Topping: Almond flour browns faster than crackers, so watch the casserole in the last few minutes. You want the Parmesan topping golden and crisp, not dark. Tent it with foil if it colors too quickly.
Drain Your Add-Ins: If you stir in vegetables like spinach or mushrooms, cook off their water first. Excess moisture is the main thing that makes a creamy casserole turn out loose instead of luscious.
Let It Rest Before Serving: Give the casserole 5 to 10 minutes out of the oven before scooping. The sauce sets up as it cools slightly, so the portions hold together instead of running.
Storage and Serving Suggestions
Refrigerator Storage: Keep leftovers in an airtight container for up to 4 days. The topping softens a little, but a 10 to 15 minute reheat in a 350°F oven crisps it right back up. The microwave works in a pinch.
Freezer Storage: This casserole freezes beautifully for up to 3 months. Freeze individual portions in meal-prep containers, thaw overnight in the fridge, then reheat. It is an easy way to keep diabetic-friendly lunches on hand.
Meal Prep Strategy: Assemble everything except the topping up to 24 hours ahead, then add the topping just before baking. For more make-ahead ideas, browse our keto lunch recipes.
Complete the Meal: A crisp green salad, roasted asparagus, or green beans all make great low-carb sides. A broccoli and cauliflower casserole rounds out a cozy, low-carb spread nicely.
