Whenever I’m after a quick and cozy meal without a lot of effort, this Fajita Chicken Casserole is what I fix. Each gooey, cheesy bite is bursting with fajita-style flavor and it always disappears fast at my house. It's laid-back enough for busy evenings but fun to whip up when friends swing by unexpectedly.

I whipped this up for a Saturday movie night ages ago. The whole tray was gone before we even started the film, and my family asks me to make it all the time.

Tasty Ingredients

  • Shredded Mexican blend cheese: melts into that bubbly golden layer on top Grab a block and shred it yourself if you can for the dreamiest melt
  • Fajita seasoning: brings the zesty kick you expect Choose your favorite or use a low-salt mix if you want control
  • Chicken broth: adds juiciness and richness Go for homemade or a decent store brand
  • Diced tomatoes with chilies: don't drain these, you want all that tomato juice and a mild heat
  • Frozen bell pepper and onion blend: keeps things easy and no need to chop anything—just pour it in for that classic fajita pop
  • Sour cream: makes it extra creamy You’ll get the best flavor if you use the full-fat kind
  • Cream of chicken soup: binds it all together and keeps it velvety Use a low-salt can if that matters to you
  • Instant rice: gets fluffy fast and soaks up every bit of flavor Stick to brands you’ve had good luck with
  • Shredded cooked chicken: hearty, simple, and saves so much time Rotisserie chicken works awesome right off the bone

Simple Steps

Add Cheese and Finish Baking:
Carefully uncover, toss the last bit of shredded cheese over everything, and put it back in for another ten minutes or until the cheese bubbles like crazy along the edges.
Bake Covered:
Tightly wrap it with foil, bake thirty-five minutes at 350 degrees, and let the steamy oven soften the rice and boost the flavors.
Layer in the Dish:
Dump the whole mix into your oiled baking pan, spread it smoothly to the edges, and make sure it's even for perfect scooping later.
Mix the Base:
In a big bowl, stir together cooked chicken, instant rice (no need to precook), cream of chicken soup, a scoop of sour cream, the frozen peppers and onions, undrained tomatoes and chilies, chicken broth, your fajita seasoning, and about half the shredded cheese. Mix well so everything looks creamy and all the rice gets wet.
Prep Your Pan:
Mist a large baking pan (about nine by thirteen inches) with oil or cooking spray. That way it slides out and you won't lose those tasty edges.

That crispy, cheesy edge is what I go for every time. My niece once told me the corners tasted like nachos and begged for seconds. Now I always leave it in the oven a couple minutes longer just for her.

Storage Tips

Let it cool off before covering it up, then stash it in your fridge for up to four days. Freezing? Scoop single servings into sealed containers and keep for three months. Pop it in the oven or microwave until it's hot all the way through and you’ve got an easy meal.

Ingredient Swaps

Turkey or cooked pork both work great here—no changes to how you make it. White or brown instant rice will do, but brown may need a splash more broth. Greek yogurt swaps in fine if you’re out of sour cream.

Best Ways to Eat

I usually plate it with a cool, crunchy salad and handfuls of tortilla chips for fun. If you’re craving something different, roll spoonfuls into a tortilla for a quick burrito. A little avocado or an extra spoonful of sour cream on top brings everything together.

Story Behind It

Dishes like this are staples in a lot of American homes, pulling big flavor from Tex-Mex favorites like fajitas that started in the Southwest. It's filling, crowd-pleasing, and you’ll spot different spins of it everywhere—from family tables in the Midwest to potlucks down South.

FAQs About the Recipe

→ Could I use rice I just cooked instead of instant rice?

You'll want to go with instant rice so it soaks up just the right amount of liquid in the dish. Freshly cooked rice doesn’t need to cook twice, so your casserole might turn out dry.

→ What if I don't have cream of chicken soup around?

Feel free to swap in cream of celery or mushroom soup, or throw together a quick white sauce if you like homemade better.

→ Will this turn out spicy?

Spiciness really depends on your chilies and fajita spice. Go for mild varieties or leave chilies out if you don’t want heat.

→ Is it okay to make this ahead of time?

Definitely. Put it together and chill in the fridge, then just bake it later. If it's cold from the fridge, tack on a few extra minutes in the oven.

→ What should I serve this with?

Toss a quick green salad, slice up some avocado, or heat up tortillas to round out your meal and add more crunch or creaminess.

→ Can I freeze leftovers?

Yep! Freeze your casserole either before or after baking. Make sure it’s wrapped well and later reheat in the oven until blazing hot.

03 2 cups (370 g) uncooked minute white rice
04 1 cup (140 g) frozen diced onion and bell pepper combo

09 360 ml chicken stock

Step-by-Step Guide

Step 01

Spray a 23x33 cm (9x13-inch) baking pan with a little nonstick spray so things don’t stick.

Step 02

Toss the chicken, dry rice, creamy chicken soup, sour cream, frozen onions and peppers, tomatoes with chilies, chicken stock, fajita seasoning, and half the cheese into a big bowl. Stir really well so everything gets blended.

Step 03

Scoop the mixture into your prepared baking dish and smooth out the top with a spatula.

Step 04

Pop some foil over the top and slide the dish into a 175°C oven. Let it bake for 35 minutes.

Step 05

After 35 minutes, peel off the foil. Scatter the rest of the cheese evenly. Bake uncovered for about 10 minutes more until the cheese looks bubbly and melty.

Additional Notes

  1. Let it chill for 5 minutes out of the oven—cuts easier this way and keeps its shape.
