Recently chicken divan popped into my head. I haven't had that casserole dish in more than 10 years, but it was one I always used to make before I went gluten free. It was an easy dish to throw together with cooked chicken, broccoli, cream of chicken soup and cheese. So, with that as my flavor inspiration I created this chicken broccoli and potato casserole - and I have to say, it might be more delicious than I remembered.
I had to make this recipe a few times to get the seasoning and the creaminess just right without cream of chicken soup, but no one was complaining. I am pretty sure this has become an overnight family favorite that will be in our regular dinner rotation.

Ingredient Notes
Most of the ingredients needed here make up the dairy free cheese sauce that is poured over the casserole. The flavor of the sauce is like a cross between cream or chicken soup and cheese. It's easy to make and it really ties everything together.
- Potatoes - I like to use mini Yukon gold potatoes that have been cut into bite sized pieces. If you only have larger potatoes, just cube them.
- Vegan Butter - I use Country Crock plant butter for most of my cooking and baking. Any vegan butter will work here. If you're not dairy free, use unsalted dairy butter in the same measure.
- Gluten Free Flour Blend - I have used Bob's Red Mill gluten free flour for this recipe. However, due to the small amount of flour used, any brand of gluten free flour will work, just don't try to sub something like almond flour. If you don't have gf flour, use 2 Tablespoons of cornstarch instead.
- Non-Dairy Milk - I've used unsweetened coconut milk, which I use for almost all of my cooking. Use your favorite type of unsweetened non-dairy milk and if you're not dairy free just used whole milk or 2%.
- Nutritional Yeast - This ingredient gives the tangy cheese flavor we are looking for in the sauce.
- Lemon Juice - Another ingredient that is used to mimic the complex flavor of cheese. If you don't have lemon juice, use apple cider vinegar.
- Garlic Powder & Onion Powder - I've used dried spices to make the preparation easier without having to chop and saute extra vegetables.
- Paprika - This helps with the color of the sauce, so it looks more cheesy.
- Broccoli - You'll want about one head of broccoli. You can add more or less to suit your taste. Use fresh broccoli florets as frozen will release too much water during baking.
- Cooked Chicken - I like to use a rotisserie chicken to make this recipe quicker to prepare. However, if you have leftover roasted chicken or want to cook chicken fresh for this recipe you can go that route.
- Vegan Parmesan - I've added a little sprinkle of vegan parmesan just to reinforce that cheese flavor. It's optional though and you can leave it off or use another vegan cheese you like.
- Gluten Free Bread Crumbs - My favorite brand is Schar. I think gluten free panko or even crushed up gluten free crackers would make a great substitute if you don't have bread crumbs on hand.

- Not Dairy Free - use dairy butter, milk and cheese in the same measure.

Storage
Store leftover casserole in an airtight container in the refrigerator for up to 3 days. The bread crumb topping will soften during storage. Reheat leftovers to 165 degrees before serving.
Recipe FAQs
I really recommend making this casserole with fresh broccoli. Frozen broccoli will release water during baking and may make the casserole too wet.
You can assemble this recipe ahead of time and store it in the refrigerator before baking. You can also completely cook this casserole and refrigerate it afterwards. Reheat the casserole in a 350 degree oven for about 30 minutes or until warmed through.
