Step‑by‑Step Instructions for Broccoli Chicken Divan Casserole
Step 1: Prepare Ingredients
Begin by gathering all your ingredients for the Broccoli Chicken Divan Casserole. If your chicken isn’t cooked yet, you can poach or roast it before shredding into bite-sized pieces. Meanwhile, bring a pot of water to a boil and blanch the broccoli florets for 2-3 minutes until they turn bright green, then immediately transfer them to a bowl of ice water to halt the cooking process.
Step 2: Make Sauce
In a large mixing bowl, combine mayonnaise, sour cream, grated Parmesan, lemon juice, and Dijon mustard. Use a whisk to blend these ingredients until your sauce is creamy and smooth, ensuring there are no lumps. Sprinkle in the garlic powder, onion powder, salt, and pepper to taste, mixing well to incorporate all the flavors.
Step 3: Assemble Casserole
Preheat your oven to 350°F (175°C). Grease a 9x13 inch baking dish with cooking spray or butter to prevent sticking. Start layering the casserole by placing the shredded chicken evenly at the bottom of the dish. Next, gently arrange the blanched broccoli florets on top of the chicken, preparing a solid base for your creamy sauce.
Step 4: Pour Sauce and Add Toppings
Carefully pour your prepared sauce over the layers in the baking dish, making sure to cover the chicken and broccoli evenly. This will create a luscious, creamy texture throughout the casserole. Then, sprinkle the shredded cheddar cheese and breadcrumbs generously over the top to create a delicious, crunchy crust that will enhance the flavor of the Broccoli Chicken Divan Casserole.
Step 5: Bake and Serve
Place the assembled casserole in the preheated oven and bake for 25–30 minutes. You’ll know it’s done when the cheese is melted, bubbly, and slightly golden on top. Once out of the oven, let it rest for 5-10 minutes to allow the flavors to meld. Serve warm, garnishing as desired, for a beautiful presentation that is sure to please everyone at your table.

Make Ahead Options
Preparing this Broccoli Chicken Divan Casserole ahead of time is a smart move for busy home cooks! You can easily assemble the casserole up to 24 hours in advance; simply layer the chicken, broccoli, and sauce in a greased baking dish, then cover tightly and refrigerate. This allows the flavors to meld beautifully. To maintain quality, keep the breadcrumbs and cheese separate until just before baking. When you're ready to serve, preheat your oven and sprinkle on the toppings before baking at 350°F (175°C) for 25–30 minutes until bubbly and golden. This effortless planning saves time and ensures your casserole is just as delicious!
