I’m alllll about the casseroles in winter. They’re warm, filling, and comforting. This week I took my favorite Broccoli Cheddar Casserole and beefed it up a bit. …Er, chickened it up a bit. I added a couple more vegetables, little juicy chicken bits, and turned it into a complete meal. This Cheesy Chicken Vegetable and Rice Casserole is all the creamy comforting goodness you’ll need for winter survival. #thestruggleisreal
Cheesy Chicken Vegetable and Rice Casserole
Day Old Rice Works Best
Just as with fried rice, day-old or chilled rice works best for this recipe because it’s a little more firm, allowing it to combine easily with the other ingredients without getting mushy. So, this Cheesy Chicken Vegetable and Rice Casserole is excellent for using up leftover rice, or if you like to cook big batches of rice and freeze it.
One more note. If you want cheesy but just not super-duper cheesy, simply skip the layer of cheese on top and bake as-is (cover with foil), or top it with buttered bread crumbs for a crunchy topping. And yes, you can use brown rice for this.
P.S. I ate this for breakfast this morning and I’m not even sorry about it.
Cheesy Chicken Vegetable and Rice Casserole

Ingredients
- 1/2 lb frozen broccoli florets ($0.85)
- 1 boneless, skinless chicken breast (about 2/3 lb.) ($1.26)
- 1 Tbsp olive oil ($0.16)
- Pinch of salt and pepper ($0.05)
- 1 yellow onion ($0.32)
- 2 carrots ($0.33)
- 4 cups cooked long grain rice ($0.75)
- 3 Tbsp butter ($0.40)
- 3 Tbsp flour ($0.02)
- 1 cup chicken broth* ($0.13)
- 1 cup whole milk ($0.38)
- 1/2 tsp salt ($0.02)
- 1/4 tsp smoked paprika ($0.02)
- Freshly cracked pepper ($0.05)
- 8 oz medium cheddar, shredded ($2.00)
Instructions
- Take the broccoli out of the freezer and allow it to begin to thaw. Once it's soft enough to cut with a knife, cut the florets into smaller, bite-sized pieces.
- Cut the chicken breast into small 1/2-inch cubes. Season with salt and pepper. Heat a large skillet over medium, then add the olive oil and swirl to coat the surface. Add the chicken pieces and cook until slightly browned on the outside. Remove the chicken pieces to a large clean bowl.
- While the chicken is cooking, finely dice the onion, and peel and slice the carrots. Add the onion and carrots to the skillet after the chicken is removed and sauté until the onions are softened. Transfer the onions and carrots to the bowl with the chicken.
- Add the chopped broccoli florets (even if not fully thawed) and the cooked rice to the bowl with the chicken, onions, and carrots. Stir to combine, then add 1/2 of the shredded cheddar (about 1 cup) and stir to combine again. Set the mixture aside.
- Begin to preheat the oven to 350ºF and coat the inside of a 2 quart casserole dish with non-stick spray. Add the butter and flour to the same skillet used to cook the chicken and vegetables. Cook and whisk the butter and flour over medium heat until it begins to foam, then continue to stir and cook for one minute.
- Slowly whisk the chicken broth into the flour and butter mixture. Allow it to come up to a simmer, at which time it will thicken. Once thickened, whisk in the milk and allow it to come up to a simmer again. When it's thick enough to coat a spoon, season with smoked paprika, freshly cracked pepper, and salt.
- Pour the sauce over the rice mixture in the bowl and stir until everything is combined and coated in sauce. Transfer the mixture to the casserole dish. Sprinkle the remaining shredded cheese over the casserole.
- Bake the casserole, uncovered, for about 35 minutes or until it becomes golden brown around the edges. Serve hot.

Step by Step Photos
Begin by taking 1/2 lb. broccoli florets out of the freezer and allowing them to begin to thaw. Once soft enough to cut with a knife, chop them into smaller bite-sized pieces, then set them aside. Cut one boneless, skinless chicken breast into small pieces (about 1/2 inch) and season with salt and pepper. Heat a large skillet over medium, then add 1 Tbsp olive oil and the chicken pieces. Cook the chicken until it is golden brown, then remove it to a large clean bowl.
While the chicken is cooking, dice one onion, and peel and slice two carrots. After removing the chicken, add the onion and carrots to the skillet and sauté for about 5 minutes, or until the onions are soft and transparent. Transfer the carrots and onions to the bowl with the chicken.
Add the partially thawed broccoli and 4 cups cooked rice to the bowl as well, then stir to combine. The cold broccoli and rice will help cool the chicken and vegetables enough so that they don’t melt the cheese in the next step.
Add half of the 8oz. shredded cheddar to the bowl and stir to combine again. Set this mixture aside. Begin to preheat the oven to 350ºF, and coat the inside of a 2 quart casserole dish with non-stick spray.
To the same skillet used for the chicken and vegetables, add 3 Tbsp butter and 3 Tbsp flour. Cook and whisk these two together over medium heat. It will start out looking like a paste, then it will begin to bubble and foam. Once it starts foaming, cook and stir for one minute.
Then whisk in one cup chicken broth and let it come up to a simmer…
At which point it will thicken to a pudding-like consistency.
Then whisk in one cup whole milk and let it come up to a simmer again, at which point it will thicken to a nice sauce. Season the sauce with 1/4 tsp smoked paprika, some freshly cracked pepper, and about 1/2 tsp salt (you want it to be fairly salty so that it doesn’t get too diluted once mixed with the rice and vegetables). The orange-y color above is due to the smoked paprika.
Pour the sauce over the rice mixture in the bowl and stir to combine. Spread the mixture into the prepared casserole dish.
Cover with the remaining 4oz. shredded cheddar and bake for about 35 minutes at 350ºF, or until it begins to brown around the edges.
And then the cheesy goodness is ready to devour!
Srsly. Yes.
Can you not say add 4 cups of rice? There is no where where it said “cooked rice” so I made 4 cups of rice which was A LOT and the flavour is so diluted. Please in the future inform us the uncooked amount please
Hi Sam. The recipe card says 4 cups of cooked rice.
You know, I’m not usually a casserole person, but I had chicken, carrots, and leftover rice to use up, so I thought why not? You’ve converted me. I really enjoyed this, as did my family. The only (minor) problem I had was the carrots stayed a bit too firm for my liking, but that’s just personal preference. Do you foresee any issues if I simply grate/shred the carrots next time? Not sure if that would risk overcooking or not. In any case, thanks for another delicious recipe!
Love this recipe? Do you think this can be thrown together ahead of time and baked the next day?
Yes, I think that would work! You may need to bake slightly longer since it will be chilled through when going into the oven instead of warm.
This was absolutely delicious! We used fresh broccoli instead of frozen(just what I had on hand) and did no salt so our one year old could eat it as well. He LOVED it! Definitely a plus when the picky eater wants seconds! :) will definitely be keeping this for our meal rotations!
Loved the sound of this recipe right away. We come to Budget Bytes for affordable recipes we can reheat and eat throughout the week as part of our meal prep. This one will definitely be made again!
Edit: we’ve now made this recipe two more times and somehow the rice has not cooked. It worked perfectly the first time- any ideas?
Without being there, it would be hard for me to say. It could be a measurement thing, or a humidity thing. It’s also all about the kind of rice you use. Longer grains require more liquid and shorter grains require less. Where do you think you went wrong? XOXO -Monti
