HOW TO MAKE CHICKEN FAJITA CASSEROLE

1. Saute the Veggies - Add oil to a large sauté pan over medium-high heat and allow it to come to temperature. Then, add in sliced onion and bell pepper and sauté for about 10 minutes, just until they have softened.
2. Make the Sauce -Sprinkle the flour on top of the vegetables and stir until the veggies are coated with it. Next, add the chicken broth one big splash at a time and take care to stir well after each addition. This will ensure you have a nice smooth sauce! Lastly, add the milk, taco seasoning, and salt, and stir! Allow your mix to simmer for about 3 minutes, or until it has slightly thickened.
3. Mix - In a large mixing bowl, combine the cooked and shredded chicken, the cooked rice, the sauce, and half of the shredded Monterey Jack and Cheddar cheese.
4. Bake - Transfer the contents of the bowl to a greased 9x13" casserole dish and top with the remaining cheese. Cover the casserole dish with aluminum foil and bake for 25 minutes at 350°F. Then, uncover and bake for about 10 minutes more.

CHICKEN FAJITA CASSEROLE INGREDIENTS

The ingredients for this souped-up Chicken Fajita Casserole can be summed up with four simple components: the sauce, chicken, rice, and cheese!

Below you'll find tips for working with ingredients, as well as ingredient substitution options!

THE SAUCE

The sauce for this creamy Chicken Fajita Casserole begins with your basic fajita veggies: You'll want to have red and green bell pepper, as well as a white onion. If needed, you can get away with using a duo of any bell pepper color combination, and as far as the onion goes, feel free to sub in yellow or red if it's what you have on hand!

In addition to the fajita veggies, you'll also need oil, all-purpose flour, chicken broth, milk, and taco seasoning for the sauce.

You can use any oil you'd like, although our favorites for cooking Mexican food are flavorless oils with high smoke points, like either canola or avocado oil. As far as the flour goes, you really should stick with all-purpose flour, but feel free to sub in a gluten-free all-purpose flour if needed.

It's best if you can use an unsalted or low-sodium chicken broth in your sauce. This way you have complete control of the flavors in your Chicken Fajita Casserole!

However, if you only have the regular chicken broth, go ahead and sub it in, but be sure to omit the additional salt in the recipe. Once you've got your sauce, chicken, and rice all mixed up in the mixing bowl, give a taste, and if it needs more sodium, add a pinch or two of salt at a time to suit your tastes. Remember -- you can always add more, but you can't take away!

Milk adds a nice creamy vibe to the sauce for this Chicken Fajita Casserole. The higher the fat content in the milk, the creamier it'll be. For this reason, whole milk gets our vote, but if you only have 2% milk, it'll work in a pinch.

And the last ingredient falling under the "sauce" category, is taco seasoning. The difference between taco seasoning and fajita seasoning is rather minimal so there's no need to whip up a fancy spice blend -- taco seasoning will do the trick just fine! Our go-to brand is McCormick's, and one 1-ounce packet is all you need.

CHICKEN OPTIONS

You'll need about 2 cups of cooked and shredded chicken for your Chicken Fajita Casserole, which typically equals about 1 pound of cooked chicken breasts.

My go-to recipe for shredding chicken is this simple oven-baked chicken breast, seasoned with simple spices that go along well with any flavor profile. If you're looking to make two meals out of one, start with a whole-roasted chicken one night, and the next night, put the leftovers to good use in this Chicken Fajita casserole! If you want to mix white and dark meat, that's ok! You can use what you have on hand.

And, of course, there's the extra easy way out -- a store-bought rotisserie chicken.

RICE

This part is about as simple as it gets! You need 4 cups of cooked white, long-grain rice. Try your best not to overcook it! It will continue to cook as it bakes in the oven and you don't want it baking to mush by the time the dinner bell rings.

THE CHEESE

This Fajita Chicken Casserole has cheese both in the casserole and on top of the casserole. For the tastiest, creamiest results, use freshly grated cheese over the pre-shredded stuff! You'll need an 8-ounce block of Cheddar and an 8-ounce block of Monterey Jack cheese.

These two kinds of cheese make up your classic Mexican or Tex-Mex blend, and if you don't have time to grate your own, just grab yourself a bag of high-quality shredded cheese. Just be sure you have 3 cups of shredded cheese total!
