There’s something about the mix of sizzling bell peppers and warm spices that pulls you into the kitchen. I remember the night I first made this low calorie chicken fajita casserole—my mind was halfway through a grocery list when the aroma of cumin and smoked paprika filled the air, making me pause. The colors alone, reds, greens, and yellows mingling with the tender chicken, made the whole process feel like less of a chore and more like a little celebration. I wasn’t in a rush, though I might have been a bit distracted by the sound of the timer ticking down somewhere in the background.
What really sticks with me about this dish is how it manages to feel indulgent without tipping the scales. That balance is rare. The cheese melts just enough on top, adding a comforting touch without overpowering the fresh, vibrant vegetables. It’s the kind of meal that’s easy to imagine on a chilly evening, wrapped in a blanket with a good show playing, but also just as welcome when you’re trying to eat a little lighter after a long day.
- Bright, colorful veggies bring a fresh crunch that makes this casserole anything but boring.
- Lean chicken breast keeps it filling but mindful, perfect for those watching calories.
- The spices give it a lively kick, though it’s never overwhelming—just enough to make you want a second helping.
- It’s simple—and that’s kind of the point. No complicated steps, just straightforward flavor.
- A little bit of melted cheese on top adds comfort without masking the healthy ingredients underneath.
If you’re worried about prep time, this dish comes together faster than you might expect, especially if you’re used to fussier meals. And while it’s tempting to pile on extra cheese or sauce, holding back actually lets the fresh ingredients shine through, which I appreciate more each time I make it.

Ingredients
1 pound boneless skinless chicken breast, cut into 1-inch strips
1 tablespoon olive oil
1 medium red bell pepper, sliced into thin strips
1 medium green bell pepper, sliced into thin strips
1 medium yellow bell pepper, sliced into thin strips
1 medium onion, sliced into thin strips
2 cloves garlic, minced
1 teaspoon chili powder
1 teaspoon ground cumin
1/2 teaspoon smoked paprika
1/2 teaspoon dried oregano
1/4 teaspoon salt
1/4 teaspoon black pepper
1 cup low sodium chicken broth
1/2 cup canned diced tomatoes, drained
1/2 cup reduced-fat shredded Mexican cheese blend
1/4 cup chopped fresh cilantro
Instructions
Preheat the oven to 375°F (190°C).
Heat olive oil in a large skillet over medium-high heat.
Add the chicken strips to the skillet and cook for 4-5 minutes until lightly browned but not fully cooked through. Remove chicken from skillet and set aside.
In the same skillet, add the sliced red, green, and yellow bell peppers and onion. Cook for 5 minutes until slightly softened.
Add the minced garlic, chili powder, ground cumin, smoked paprika, dried oregano, salt, and black pepper to the vegetables. Stir well and cook for 1 minute until fragrant.
Return the chicken strips to the skillet and stir to combine with the vegetables and spices.
Add the low sodium chicken broth and diced tomatoes to the skillet. Stir to combine and bring to a simmer.
Transfer the entire mixture into a 9×9-inch baking dish, spreading evenly.
Sprinkle the reduced-fat shredded Mexican cheese blend evenly over the top.
Bake in the preheated oven for 20 minutes until the cheese is melted and bubbly and the chicken is cooked through (internal temperature should reach 165°F or 74°C).
Remove from oven and sprinkle chopped fresh cilantro over the casserole before serving.

Don’t worry if you don’t have a fancy baking dish—any oven-safe dish about 9×9 inches will do just fine, and cleanup is pretty straightforward. This casserole pairs wonderfully with a simple side salad or some warm tortillas if you’re feeling a bit indulgent. I’ve tried swapping out the bell peppers for whatever veggies were lurking in the fridge; sometimes zucchini or mushrooms sneak in, though I haven’t tested all substitutions extensively. A sprinkle of extra cilantro right before serving always feels like a little finishing touch that brightens the whole dish.
FAQ
Can I make this ahead of time? Yes, you can prep everything except baking and refrigerate it for a few hours. Just add a few extra minutes in the oven when you bake it.
Is this recipe freezer-friendly? I wouldn’t recommend freezing it because the texture of the peppers can get a bit mushy after thawing.
What if I don’t have Mexican cheese blend? A mild cheddar or Monterey Jack works well in a pinch.
Can I use chicken thighs instead of breast? Definitely, though cooking times might vary slightly.
When you’re ready for a dinner that’s satisfying without the heaviness, give this casserole a try. It’s comforting in all the right ways and just might become one of those dishes you turn to when you want something homey but not complicated. Save it, print it, and dig in—you won’t regret it.
