Recipe Notes
- Cooking Vegetables – The peppers and onions are a little crunchy in this recipe and I love it that way but if you prefer softer veggies, sauté them for 3-5 minutes in oil before mixing them in with the other ingredients.Â
- Cooking Casserole – We cook the casserole covered with foil to prevent the top from burning.
- Rotisserie Chicken – This is a great recipe to use leftover cooked chicken or rotisserie chicken.
- Low Carb – You can substitute the regular white rice with cooked cauliflower rice or serve the casserole over the cauliflower rice.
- Add Beans or Corn – This makes for a heartier casserole.
- Extra Creamy – Add a block of softened cream cheese.

I hate instant rice. Can I use regular white or brown rice? Maybe cokk it alone 1st?
Amy – Yes, regular rice can be used instead but I would cook it before adding it to the casserole as it would have to bake a long time to get cooked all the way through. If you try it out, please come back and let me know what you think!
Your recipes are fantastic!
If I add the optional cans of pinto beans and/or corn, should I drain them or does the rice need the extra liquid?
I would drain them both and rinse the beans.
