I absolutely love this Chicken Broccoli Casserole. Perfectly-cooked broccoli, tender and juicy white meat chicken, with an incredibly creamy and cheesy sauce – what more could you ask for? And to top it all off, it’s a healthy and easy recipe – no processed ingredients in sight! Awesome, right?
CHEESY BROCCOLI CHICKEN CASSEROLE (CHICKEN DIVAN)
Everyone loves a warm and classic casserole like Chicken Divan, or as it’s more commonly known, Chicken Broccoli Casserole. Many recipes call for condensed soups to get that smooth and creamy cheese sauce, but this one uses just cream, broth, real cheese, and a tiny bit of natural cornstarch – so it’s low carb, gluten-free, and healthier all around!
You’ll love how the tender chunks of chicken breast pair with mushrooms, broccoli florets, and the cheesy, herb-y sauce. It’s comfort food you can truly feel happy about!
CASSEROLE INGREDIENTS
- Cooked Chicken Breast: You’ll need 1-1 ½ pounds cooked chicken breast, shredded or chopped. Rotisserie chicken can be substituted.
- Olive Oil
- Baby Portobello Mushrooms: Also known as Crimini.
- Broccoli Florets: About 4 cups total. Baby broccoli florets are great, but you can also use regular florets – if you do, cut larger florets into small, bite-sized pieces.
- Fresh Garlic: Mince or put through a garlic press.
- Salt and Pepper
- Dried Basil, Oregano, and Thyme
- Mozzarella Cheese: About 8 oz. shredded mozzarella, divided.
- Chicken Broth: I use low-sodium broth.
- Cornstarch
- Heavy Whipping Cream: You’ll need ½ cup of cream; half-and-half may be substituted but the sauce may not be as thick.
- Chopped Fresh Parsley: For garnish
HOW TO COOK CHICKEN BREAST
- If you’re preparing the chicken breast for this dish, rather than using rotisserie, my Stove Top Chicken Breast method is super fast and easy. Simply season the chicken breasts, sear them for about 6-7 minutes per side, and finish with a tablespoon of butter. That’s it! (Tip: Use a meat thermometer to check for doneness, and make extra! These freeze beautifully and come in handy for a quick meal!)
HOW TO MAKE CHICKEN BROCCOLI CASSEROLE
- Chop/Shred the Chicken and Layer in Baking Dish: Preheat the oven to 350ËšF. Lightly grease a 9×13 baking dish with cooking spray. Then shred or chop the cooked chicken and arrange in the baking dish.
- Saute the Veggies: Heat olive oil in a large skillet over medium-high heat. Add mushrooms to the hot oil and cook for 2 minutes. Stir in broccoli and garlic; season with salt, pepper, basil, and oregano, and continue to cook for 3 more minutes. Layer this mixture over the chicken.
- Make the Sauce: In a small mixing bowl, combine a tablespoon of chicken broth with cornstarch and whisk until pasty. Add the remaining chicken broth to the hot skillet; whisk in cornstarch paste, heavy cream, thyme, salt, and pepper. Cook until it just starts to thicken.
- Add the Sauce to the Casserole: Pour this sauce over the chicken mixture, and stir well; sprinkle with remaining cheese.
- Bake and Serve: Cover the baking dish with foil and bake for 15 minutes. Remove foil bake for 9 to 10 more minutes, or until light golden on top. Let stand 10 minutes before serving.
- Enjoy!
TIPS FOR MAKING THIS CASSEROLE AHEAD
Follow these tips for the best results!
- To make this casserole ahead, first prepare the chicken, veggies, and sauce separately.
- If freezing, place the prepared chicken, veggies, and sauce in individual freezer bags, pushing out as much air as possible before sealing. Freeze for up to 3 months. To bake, thaw ingredients overnight in the refrigerator, assemble the casserole the following day, and bake according to the recipe.
- If refrigerating, assemble the entire casserole up to the point of baking. Cover and refrigerate for up to 2 days.
- Bake and serve according to recipe instructions. Do not store or freeze leftovers.
SERVING SUGGESTIONS
- This dish has a lot of indulgent umami flavor, thanks to the mushrooms, cheese, chicken, and broccoli. I like to pair it with something light, yet earthy as a contrast. Try my Radish Cucumber Tomato Salad as a side or starter.
- A simple side of Maple Roasted Carrots adds color and sweetness to the menu, creating a hearty meal with very little effort!
- You can also serve this casserole with a Light Skillet Cornbread for the main course, followed by a surprising dessert, like my Strawberry Pretzel Dessert, to round out the menu.
HOW TO STORE AND REHEAT CHICKEN BROCCOLI CASSEROLE
- Store leftovers in tightly-covered containers, or in individual portions sealed in plastic food-storage bags, for up to 3 days.
- Store leftovers in the freezer, tightly wrapped and sealed, for up to three months.
- Do not store leftovers if the casserole was previously made ahead and frozen before baking.
- To reheat, thaw the casserole in the refrigerator (if frozen). Bake the leftovers at 350ËšF, covered, until heated through.

But the time I located the ingredient list proportions it was close to not worth the effort and time expended.
I made this last night but increased the quantities because my people can eat 😀 . It came out amazing. My mozzarella cheese was a mix with maasdamer (a little sharper) and it came out soooooo good. The entire tray was finished. Thank you!
Is there any substitutions that can be made to cut the fat content?
Hi!
You can use fat-free or low fat shredded cheeses, and you could also use half & half in place of the heavy cream.
Hi. How much of the mozzarella should be added to the sauce? Ingredients say 8oz divided and instructions say nothing about adding to sauce just to top with remaining. I’m sure I can just use best judgement and it would still be good, but I’m curious about the recommended amount. Thank you.
Hi!
You want to add half of the shredded cheese to the sauce, and sprinkle the rest of it on top of the casserole; see step 4 and step 5 in the recipe box. I hope this helps.
Meh. Not much flavor, even adding onions and a little sherry to the sauce.
Did you try adding more salt? That’ll usually do it. Not always, but most times, a little more salt is key.
Can you cook this in a crockpot? Also can you add squash and zucchini if you want, what adjustments would need to be made?
Can I make this ahead and leave in the fridge for a few hours before baking?
Hi!
Yes, that will definitely work.
Anything I can use to substitute the mushrooms?
Hi!
You can just leave them out completely, or you can maybe try using slices of zucchini, or any other squash. Sundried tomatoes would also go well.
This was really good!! I loved it! My family was so happy with it!
I am very glad you and your family enjoyed it! Thank YOU! 🙂
This was delish. Next time I make it I’m going to double the sauce. If you like to serve over rice or noodles if needs more liquid (I did use heavy cream). Love a recipe that doesn’t use soup!
Adding this to my must try list! This looks absolutely delicious!
Thank YOU! I hope you enjoy it! 🙂

When I am trying to see the instructions and ingredients I don’t appreciate a video of another recipe covering part of the instructions.
Why can’t you store the leftovers if this was frozen ahead and the baked??
Hi!
That would be because of the heavy cream. Cream-based casseroles curdle when thawed and reheated.
