Why We Love It

When I’m craving a good homecooked meal, I think of casseroles. Aren’t they the best? I love that there really aren’t any set rules when making one, other than considering the typical categories like a protein, starch and vegetable.

The possibilities are endless when you think of how many different foods can come into play–and how many of them compliment each other in a palatable way. Speaking of great flavors, have you tried Chow Mein Beefy Rice Casserole yet?

To me, chicken and rice are one of the best pairings of all time, so why not use that base to create a tasty casserole–especially when you have leftover chicken in the fridge? (Meal prep time cut down significantly?–check!)

This Chicken Veggie Rice Casserole has many basic, staple ingredients that come together nicely to create a great meal. Cooked rice and leftover/precooked chicken are mixed together with diced green peppers, onions, celery and pimentos for a colorful, textured variety. Rather than using a can of condensed soup, we make our own sauce with a bouillon packet, seasonings and mayo (trust me, it works). And of course this casserole wouldn’t be complete without some buttered breadcrumbs on top! Yum!

My family loves Chicken Veggie Rice Casserole because of the buttered topping and because we enjoy peppers, chicken and rice. I love the fact that this a great wholesome meal that uses up leftovers that feeds all four of us. Serve it with some bread and a side salad, and dinner is done!

Why You’ll Love It

Prep time cut in half- Precooked chicken makes this meal a breeze. After you chop the veggies and cook the rice (heck, you could even use instant if you wanted to), there’s not much more to it–other than mixing a few extras, making the topping (which is super easy) and popping it into the oven.

Low maintenance- It doesn’t get much easier than this. Isn’t that the true beauty of a casserole? Once the work is done, it bakes in the oven and leaves you alone until the timer goes off, giving you ample time to catch up on your favorite Netflix show!

Highly customizable- Love different kinds of peppers?–Add some. Big on seasoning?–Toss more in. Like wild rice instead?–Swap it. I think you get the idea.

Easy plating- After prep, Chicken Veggie Rice Casserole is baked in one dish. It pairs so well with a side salad and a slice of bread. That checks off all the boxes for dinner here!

Some food for thought....

Expand All:
Can I freeze this?

Yes! It will keep for about 3 months with proper freezer-safe packaging. Freeze it after it has cooked, but make sure it is completely cool before doing so. When ready to enjoy it again, defrost it overnight in your refrigerator. Then follow the reheating instructions listed above.

I don't have a 13x9 baking dish. What else can I use?

A 3-quart casserole will work fine!

Why Italian breadcrumbs for the topping? Is this an Italian dish?

I wouldn't categorize it as Italian, but I do like using Italian breadcrumbs for added flavor. If you prefer, you may use plain.
