Everything You Need to Know

All you need is one pan.

For this dish, you literally throw everything in a casserole dish UNCOOKED (even the chicken and quinoa) and pop it in the oven for 60 minutes.

Can I use other vegetables in this casserole?

Yes, you can use other vegetables in this chicken casserole. If you don’t have peppers on hand or want to use something else. Feel free to use any of your favorite vegetables. Below are some of our top substitution picks!

  • broccoli
  • cauliflower
  • pea pods
  • green beans

Does it matter what kind of quinoa I use?

I tested this with traditional white quinoa and Inca Red Quinoa.

I noticed that the red quinoa needed to cook a bit longer than the white, so just be mindful of that if you only have red on hand!

Do I need to use specific cashews in this recipe?

You can use whatever cashews you have on hand! However, we recommend using roasted salted cashews for the best flavor!

What are the best toppings for this cashew chicken casserole?

The topping options are endless for this cashew chicken casserole! Below are our go-to toppings!

  • fresh lime juice
  • cilantro
  • cashews
  • green onions

Can I freeze this cashew chicken casserole?

Yes, you can freeze this cashew chicken casserole! Make the casserole as instructed in the recipe card and then let it cool completely.

Next, cover the casserole dish with plastic wrap and then tin foil to tightly seal the casserole and place in the freezer for up to 3 months. You can also transfer the casserole into meal prep containers for single-serve options!

Cashew Chicken Casserole Tips

Here are a few tips and tricks to make sure you get the most bang for your buck when you make this chicken casserole recipe!

  • Make sure that all the quinoa is submerged in liquid before you place the casserole in the oven.
  • If you find that your chicken casserole isn’t cooking evenly, try stirring the casserole halfway through the cook time.
  • Be sure to spray your casserole dish before placing ingredients into the casserole dish. This will prevent the ingredients from sticking to the casserole dish when you are serving it!
