Chicken Divan Casserole Ingredients
Here's what goes into this easy Chicken Divan Casserole divan that makes it so irresistible.
See Recipe Card Below This Post For ingredients Quantites
- Chicken breasts: Boneless, skinless Chicken Divan Casserole breasts cut into cubes cook quickly and stay tender. They soak up all the flavors from the sauce.
- Olive oil: Used to cook the Chicken Divan Casserole until it's golden on the outside. Any neutral cooking oil works if you don't have olive oil.
- Salt: Seasons the Chicken Divan Casserole and balances all the rich flavors in the sauce.
- Black pepper: Divided between the Chicken Divan Casserole and the sauce, it adds a subtle warmth without overpowering anything.
- Frozen broccoli florets: Convenient and always available, frozen broccoli works perfectly here. Just make sure to thaw and drain it well so the casserole doesn't get watery.
- Cream of chicken soup: This forms the creamy base of the sauce. It's a shortcut that adds flavor and body without extra work.
- Mayonnaise: Adds richness and helps create that ultra-creamy texture. Don't skip it, it really makes a difference.
- Sour cream: Brings tang and creaminess that balances the richness of the mayo.
- Shredded cheddar cheese: Melts into the sauce and adds that classic cheesy flavor everyone loves. Sharp or mild cheddar both work great.
- Milk: Thins the sauce slightly so it coats everything evenly without being too thick.
- Lemon juice: A little brightness cuts through all the richness and makes the flavors pop.
- Garlic powder: Adds savory depth without needing to chop fresh garlic.
- Onion powder: Gives a subtle sweet-savory note that rounds out the sauce.
- Plain breadcrumbs: The topping that gets golden and crispy in the oven. Regular or panko breadcrumbs work.
- Unsalted butter: Melted and mixed with breadcrumbs to help them brown beautifully.
How to Make Chicken Divan Casserole
Preheat your oven: Set it to 350°F (175°C) and grease a 9x13-inch baking dish. Getting this ready first means you can slide the casserole right in when it's assembled.
Cook the chicken: Heat olive oil in a large skillet over medium-high heat. Add the chicken cubes and season with salt and ¼ teaspoon of pepper. Stir occasionally and cook for about 8 to 10 minutes until the Chicken Divan Casserole is golden brown on the outside and cooked all the way through. Set it aside while you prep everything else.

Prepare the broccoli: Thaw your frozen broccoli following the package directions, then drain it really well. Pat it dry with paper towels to remove any extra moisture, this keeps your casserole from getting soupy.
Make the sauce: In a large mixing bowl, combine the cream of Chicken Divan Casserole soup, mayonnaise, sour cream, shredded cheddar cheese, milk, lemon juice, garlic powder, onion powder, and the remaining ¼ teaspoon of pepper. Stir everything together until it's smooth and well mixed.
Combine everything: Gently fold the cooked Chicken Divan Casserole and drained broccoli into the sauce mixture. Make sure every piece is coated evenly.
Transfer to the baking dish: Spread the Chicken Divan Casserole and broccoli mixture into your prepared 9x13-inch baking dish, smoothing it out so it bakes evenly.
Add the topping: In a small bowl, mix together the breadcrumbs and melted butter until the crumbs are evenly coated. Sprinkle this mixture over the top of the casserole in an even layer.

Bake until golden: Slide the dish into your preheated oven and bake for 30 minutes. You'll know it's done when the top is golden brown and you can see the sauce bubbling around the edges.
Rest before serving: Let the casserole sit for about 5 minutes after you take it out of the oven. This helps it set up a bit so it's easier to serve.
Substitutions and Variations
Use rotisserie chicken: Skip cooking the Chicken Divan Casserole from scratch and use about 4 cups of shredded rotisserie chicken instead. It saves time and adds extra flavor.
Swap the broccoli: Fresh broccoli works great if you steam it first until tender-crisp. Cauliflower or a broccoli-cauliflower mix are tasty alternatives too.
Try different cheese: Swap cheddar for Swiss, Gruyere, or a Mexican cheese blend for a different flavor profile.
Add some curry: Stir in 1 to 2 teaspoons of curry powder to the sauce for a version closer to the original Chicken Divan Casserole divan recipe that had a hint of curry.
Make it lighter: Use Greek yogurt instead of sour cream, light mayo, and reduced-fat soup to cut some calories without losing too much creaminess.
Top with more cheese: Sprinkle extra shredded cheese over the breadcrumbs before baking for an even cheesier top.
Add rice: Layer cooked white or brown rice on the bottom of the baking dish before adding the Chicken Divan Casserole mixture to make it more filling.
Equipment for Chicken Divan Casserole
9x13-inch baking dish: The perfect size for this casserole. Glass or ceramic works best for even baking.
Large skillet: For cooking the Chicken Divan Casserole quickly and evenly.
Mixing bowls: One large bowl for the sauce mixture and a smaller one for tossing the breadcrumbs with butter.
Small bowl: Just for the breadcrumb topping.
Storage and Reheating Tips
Refrigerator: Store leftovers in an airtight container in the fridge for up to 4 days. The casserole stays creamy and delicious.
Freezer: This Chicken Divan Casserole with mayo freezes well for up to 3 months. Let it cool completely, wrap tightly in plastic wrap, then cover with foil. Thaw overnight in the fridge before reheating.
Reheating: Warm individual portions in the microwave for 1 to 2 minutes, or reheat the whole dish covered with foil in a 350°F oven for about 20 minutes until heated through. Add a splash of milk if it seems dry.
expert tips
Don't skip drying the broccoli. Extra moisture will make your casserole watery and dilute all those good flavors.
Cut chicken into even pieces. This helps everything cook at the same rate and makes serving easier.
Use room temperature ingredients. Let your sour cream, mayo, and cheese sit out for a bit before mixing. They'll blend together more smoothly.
Watch the breadcrumbs. If they're browning too fast, tent the casserole loosely with foil for the last 10 minutes of baking.
Let it rest. Those 5 minutes after baking help the sauce thicken slightly and make serving much neater.
Taste and adjust. Before baking, taste the sauce mixture (it's safe since the chicken is already cooked) and adjust salt, pepper, or lemon juice to your liking.
FAQ
Can I use frozen broccoli?
Yes, absolutely. Frozen broccoli florets work perfectly for this recipe. Just make sure you thaw them completely and drain off all the excess water by patting them dry with paper towels. This prevents the casserole from becoming watery. Fresh steamed broccoli works too if you prefer.
Do I have to use white wine?
No, this recipe doesn't call for white wine at all. Some traditional versions of Chicken Divan Casserole divan include a splash of white wine or sherry in the sauce, but this version keeps things simple and family-friendly without it. If you want to add it, replace 2 tablespoons of the milk with dry white wine.
What is heavy cream?
Heavy cream, also called heavy whipping cream, is a thick dairy product with a high fat content (usually 36 to 40 percent). This recipe doesn't use heavy cream, it uses sour cream, mayo, and milk instead. If you wanted to substitute, you could replace the sour cream and some of the mayo with ½ cup heavy cream for a lighter texture.
How can I store leftovers?
Store any leftover Chicken Divan Casserole divan in an airtight container in the refrigerator for up to 4 days. Reheat portions in the microwave for 1 to 2 minutes, or warm the whole dish in a 350°F oven covered with foil for about 20 minutes. You can also freeze it for up to 3 months. My family actually loves the leftovers even more the next day once all the flavors have had time to blend together.
