What is Chicken Divan?

Chicken Divan is a classic American casserole dish that typically consists of cooked chicken, broccoli, and a creamy sauce—all topped with grated cheese and baked until bubbly. This rich, comforting dish originated at the Divan Parisien restaurant in New York City’s Chatham Hotel in the 1930s, and was named after the restaurant.

Although the original version included poached chicken on broccoli with a cheesy béchamel or Mornay sauce, the dish that most folks recognize as Chicken Divan features a creamy sauce made from ingredients like mayonnaise, sour cream, and condensed cream of chicken soup or cream of mushroom soup. The casserole is then topped with grated cheddar cheese and/or a crispy topping (e.g., regular bread crumbs, panko breadcrumbs, or crushed Ritz crackers) and baked in the oven until the cheese is melted.

Why should you try my paleo and Whole30 Chicken Divan?

I’m always trying to recreate classic recipes with a healthier spin that’s still packed with flavor—and this recipe is no exception! Instead of cracking open a can of processed cream of whatever soup and dumping in a bunch of dairy that may not agree with you later, I created a simple and umami-packed sauce made with chicken broth, soaked cashews, nutritional yeast, Magic Mushroom Powder, and some commonly available spices. Just blitz everything together in a blender and you’re done!

Pair this Whole30-compatible creamy cheese sauce with cooked chicken, broccoli florets, and crunchy plantain chips and you’ll be looking at a new family favorite!

Can you make Chicken Divan ahead of time and/or freeze it?

Yes, Chicken Divan can be made in advance and baked once you’re ready to serve it! Assemble the casserole ahead of time (without the plantain chips) and keep it covered with foil or plastic wrap in the refrigerator for up to 24 hours before baking. When you’re ready to bake it, top it with crushed plantain chips (if using) and bake as directed.

Alternatively, you can bake the casserole in advance, let it cool, cover it, and keep it in the refrigerator for up to 4 days or in the freezer or up to 3 months. To reheat the casserole, heat the oven to 350°F and bake the thawed casserole for 20-30 minutes or until heated through.

Ingredients

  • Broccoli: You can use fresh or frozen broccoli for this recipe—just cook it until it’s tender-crisp first. Feel free to substitute different cooked veggies (e.g. peas, kale, asparagus, or green beans).
  • Cooked chicken breasts: Any leftover chicken works in this chicken casserole! You can also buy a rotisserie chicken and shred the meat into bite-size pieces for this dish.
  • Chicken broth: I use a high-quality chicken bone broth in this recipe that isn’t salted. If you use a highly seasoned broth, you can back off on the amount of Magic Mushroom Powder or salt.
  • Raw cashews: To replicate the creamy sauce without the dairy, I turn to soaked cashews. If you have a cashew allergy, you can probably substitute some coconut cream or coconut milk but beware: it will taste coconut-y.
  • Nutritional yeast: Adds cheesiness and umami flavor to the sauce! My favorite brand is Bragg’s.
  • Arrowroot powder: It thickens the sauce as it bakes in the oven! I use 3 tablespoons in this recipe because I like the sauce to stay thicker, even with reheating. If you want a thinner sauce, use less!
  • Magic Mushroom Powder: I recommend using my one-of-a-kind, indispensable seasoning blend in place of salt. It incorporates not just salt but also porcini mushroom powder (more umami!) and pepper—all the things that’ll make this casserole pop with flavor. You can make your own Magic Mushroom Powder or buy it online at The Spice Lab, on Amazon, or on iHerb (worldwide shipping!). No MMP? You can use Diamond Crystal kosher salt and a dash of Worcestershire sauce or fish sauce for a boost of umami.
  • Dried spices: To keep things simple, I add some garlic powder, onion powder, dry mustard, and freshly cracked black pepper to season this dish. If you want to kick things up a notch, you can substitute some curry powder for the spices!
  • Crushed plantain chips (optional topping): My favorite paleo crunchy topping is crushed plantain chips or strips (and my favorite brand is Artisan Tropics!). Leave off the topping if you’re doing a Whole30 because store-bought plantain chips are not allowed.

How to make Chicken Divan

Prepare the filling

Place the cashews in a large bowl and soak them in boiling water for at least 15 minutes. Drain and set aside.

Heat the oven to 400°F with the oven rack in the middle position. In the meantime, cook the broccoli florets by adding them to a large pot of boiling water…

What do you serve with Chicken Divan?

Chicken Divan can be a complete meal on its own, but you can also serve it with cauliflower rice, roasted vegetables, or a green salad if you’re trying to keep things paleo. If you don’t have dietary restrictions, feel free to serve it with rice, pasta, noodles, or bread. I won’t judge you!

How to store leftovers?

Leftover Chicken Divan can be stored in a sealed container for up to 4 days in the fridge or up to 3 months in the freezer.

    Thanks! Excited to try!
