Ingredients for Chicken Divan

Tender chicken, crisp broccoli, and rich cheese sauce come together in this timeless comfort dish.

The chicken quality matters—boneless, skinless breasts stay moist and hold their shape. Look for air-chilled at Whole Foods or Costco for better texture. Fresh broccoli should be deep green with tight florets; avoid any with yellowing or soft stems. For the cheddar, Cabot or Tillamook sharp cheddar blocks grate beautifully and melt smoothly without the anti-caking agents found in pre-shredded varieties.

Need a shortcut? Rotisserie chicken works perfectly—shred about 4 cups. No sharp cheddar? Gruyère at the same quantity offers a nutty depth. Fresh out of Dijon? Regular yellow mustard at double the amount gets you close. For a gluten-free version, swap the flour for cornstarch at half the quantity and use gluten-free panko. The milk can be 2% in a pinch, but whole is ideal.

Assemble and refrigerate up to 24 hours before baking (add 10 minutes to cook time if cold). Leftovers keep 4-5 days in the fridge. Reheat covered at 350°F until warmed through. Freezes beautifully for 3 months—thaw overnight before reheating.

Step-by-Step Instructions for Chicken Divan

This classic casserole comes together with precise technique and layered flavors.

Step 1: Prepare the Chicken and Broccoli

Preheat your oven to 375°F. Cut the 1.5 lb boneless skinless chicken breasts into bite-sized pieces and season with ½ tsp salt and ½ tsp black pepper. Sear the chicken in a skillet over medium-high heat until just cooked through, about 5-6 minutes, then set aside.

While the chicken cooks, cut the 4 cups fresh broccoli into small florets. Blanch the broccoli in boiling water for 2 minutes, then transfer to an ice bath to stop cooking. This preserves the vibrant green color and slight bite. Drain well and pat dry to prevent excess moisture in the casserole.

Step 2: Create the Creamy Cheese Sauce

In a saucepan, melt the ¼ cup butter over medium heat. Add the ½ onion, finely diced, and cook until translucent, about 3 minutes. Stir in the 2 cloves garlic cloves, minced, and cook for 30 seconds until fragrant.

Whisk in the ¼ cup all-purpose flour to form a roux, cooking for 1-2 minutes until golden. Gradually pour in the 1½ cups whole milk and 1 cup chicken broth, whisking constantly to avoid lumps. Stir in the 1 tbsp Dijon mustard, then add the 2 cups sharp cheddar cheese in batches, allowing each addition to melt completely before adding more.

Step 3: Assemble the Casserole

In a greased 9×13-inch baking dish, spread the blanched broccoli evenly across the bottom. Distribute the cooked chicken pieces over the broccoli, then pour the cheese sauce evenly over the top, ensuring all pieces are coated.

This layering method guarantees every bite includes all components. The sauce should be thick enough to cling to the chicken and broccoli without pooling excessively at the bottom of the dish.

Step 4: Add Topping and Bake

In a small bowl, combine the 1 cup panko breadcrumbs with the 3 tbsp melted butter. Sprinkle this mixture evenly over the casserole, then top with the ½ cup Parmesan cheese. The breadcrumbs create a crispy contrast to the creamy interior.

Bake uncovered for 25-30 minutes until the topping is golden brown and the sauce is bubbling at the edges. Let the casserole rest for 5-10 minutes before serving to allow the sauce to set slightly, making it easier to portion neatly.
