During recipe development, I was trying to think of ways to make the prep time on this recipe a bit shorter. Long recipe short, this one calls for cooking the components before putting it all together for a final baking. Here was my thought process for cooking each of these components and their necessity:
- Noodles – need them. Also need them to be cooked.
- Chicken – MEAT. Can use pre-cooked meat, but we don’t always have that ready to go.
- Peppers and onion – Vital for fajita-ness.
So, yeah, I couldn’t leave anything out. In another world, I see a futuristic version of this casserole made with rice that cooks INSIDE the casserole during the final baking phase. But – I wanted noodles, and I wanted them in this Chicken Fajita Casserole.
While it may be a little time consuming, this recipe just comes down to cooking a few basics and adding a few spices. Step 1: Cook the chicken. I like to use the same pan for the chicken as I will use for the casserole itself to save dishes.
Step 2: Cook your favorite kind of noodles according to the package. I cook mine to the minimum required time since they’ll cook a little more in the oven. Note: Some brands of brown rice noodles really suck. I use the Trader Joe’s Organic Brown Rice Fusilli because it seems to dry out the least, compared to other brands I’ve tried. I also like Jovial Organic Brown Rice Fusilli too.
Step 3: Cook the veggies. Also not that difficult. And super easy Step 4: Combine with remaining ingredients and bake!

- 2 teaspoons ground cumin
- 1 teaspoon chili powder
- 1/2 teaspoon cayenne pepper (optional for a little extra spice)
- 1 teaspoon garlic powder
- 1 teaspoon paprika
- 1 teaspoon salt
- 1/2 teaspoon ground black pepper
- 1 cup whole fat greek yogurt
- 4 ounces cream cheese
- 1 1/2 cups shredded cheddar jack (or blend) cheese, separated
Toppings: cilantro, avocado, salsa, olives, etc
- Preheat the oven to 425 degrees F. Line a 9×13 inch casserole dish with aluminum foil.
- Place chicken breasts in the dish, sprinkle with 1/2 teaspoon salt and pepper, flip and sprinkle with another 1/2 teaspoon salt and pepper. Drizzle with 2 tablespoons olive oil. Bake in a preheated oven for 30-40 minutes (time will vary depending on thickness of chicken). Move on to next steps while chicken is cooking. When the chicken has reached 165 degrees F inside, set aside to cool. Shred or chop into 1 inch cubes when cooled.
- While the chicken is cooking, prep all vegetables. Remove seeds, stem, and chop jalapeños. Remove seeds and stem from bell peppers, and cut into 2-inch strips. Cut onion into 2-inch strips.
- Heat a salted pot of water at high heat until boiling. Add pasta and cook according to package directions. Strain and set aside to cool when done. Drizzle with olive oil and stir to avoid sticking while cooling.
- In a large deep skillet or Dutch Oven, heat 2 tablespoons oil over medium heat. When hot, add all vegetables to the skillet. Add lime juice, a pinch of salt and a pinch of pepper. Cook for 9-12 minutes, stirring occasionally, or until the onions begin to turn translucent. Turn off the burner but leave the skillet on the hot burner.
- Add cubed or shredded chicken, cumin, chili powder, garlic powder, paprika, cayenne pepper, sea salt, and black pepper. Stir until well mixed and seasoning is evenly dispersed. Add cream cheese, greek yogurt, and 1 cup of shredded cheddar cheese. Stir until well mixed.
- Remove the foil from the 9×13 casserole dish. Leave any leftover chicken juices. Dump entire mixture into the casserole dish. Top with remaining 1/2 cup shredded cheese.
- Bake uncovered for 20-25 minutes until the top is golden brown. Optional – broil for 3 minutes at the end to crisp the top. Watch it carefully.
- Top with avocado, cilantro, salsa, or your favorite fajita toppings.
