For Chicken Fajita Casserole
- Chicken Thighs – I use boneless, skinless chicken thighs for tenderness, but you can also use chicken breasts if preferred.
- Red Bell Pepper – Adds a touch of sweetness and color to the dish.
- Onion – For a savory flavor that caramelizes perfectly while baking.
- Cream Cheese – Creates a creamy texture and adds richness to the casserole.
- Shredded Cheddar Cheese – Provides the cheesy, melty goodness that ties the casserole together.
- Fajita Seasoning – The key seasoning to bring out that bold, Mexican-inspired flavor.
- Salt & Pepper – Optional, but great for enhancing all the flavors.
Chicken Fajita Casserole
.
Ingredients:
- 10 boneless, skinless chicken thighs (about 2 lbs)
- 1 red bell pepper, seeded and sliced into thin strips
- 1 large onion, peeled and sliced into thin strips
- 8 oz cream cheese, softened
- 8 oz shredded cheddar cheese
- 1.5 tbsp fajita seasoning
- Salt and pepper to taste (optional)
Instructions:
- Preheat the oven to 350°F (175°C). Place the chicken thighs in a casserole dish and cover with foil. Bake for about 30-35 minutes, or until the chicken reaches an internal temperature of 160°F. Once done, allow the chicken to cool for a few minutes before shredding or chopping it into bite-sized pieces. Discard any excess liquid from the casserole dish.
- Cook the vegetables: While the chicken bakes, heat a frying pan over medium-low heat and coat with cooking spray. Add the sliced pepper and onion and cook, stirring occasionally, until they become golden and soft. Let them caramelize as the chicken cooks in the oven. Stir every 5-10 minutes for best results. Once cooked, set the veggies aside to cool slightly.
- Assemble the casserole: In a large mixing bowl, combine the softened cream cheese, half of the shredded cheddar, and the fajita seasoning. Stir in the shredded chicken and cooked onions and peppers. Transfer the mixture back into the casserole dish you used for the chicken. Sprinkle the remaining shredded cheddar cheese over the top.
- Bake: Return the casserole to the oven and bake for 25-30 minutes, or until it’s hot and bubbly, and the cheese is golden and melted.
Notes:
- Make-Ahead Tip: You can prepare the casserole through step 3 ahead of time and refrigerate for up to two days. When ready to bake, allow extra time (30-40 minutes) to heat it through and achieve a bubbly, golden topping.
- Adjusting Seasonings: Depending on your fajita seasoning blend, you might want to adjust the salt. After the chicken is cooked, taste and adjust the seasoning if needed.

1. Can I prepare the casserole ahead of time?
Yes! You can prepare the casserole up to the point of baking, cover it tightly, and refrigerate it for up to two days. When you’re ready to bake, just pop it in the oven. If it’s chilled, it may take a little longer to cook, so give it 30-40 minutes.
2. Can I use a different type of cheese?
Definitely! While cheddar is the classic choice for this casserole, you can use Monterey Jack, mozzarella, or a Mexican cheese blend for a different flavor. Just make sure the cheese melts well for that gooey, creamy texture.
3. Can I use chicken breasts instead of thighs?
Yes, you can. Chicken breasts are leaner than thighs, but they’ll work perfectly fine. Just keep in mind that chicken thighs tend to be juicier and more tender, but the casserole will still be delicious with breasts.
4. Can I make this dish spicier?
For sure! If you like more heat, you can add sliced jalapeños, a bit of hot sauce, or extra chili powder when mixing the seasoning. Adjust to your preferred spice level!
5. How can I save time with the prep?
To save time, chop your vegetables (onions and peppers) ahead of time and store them in the fridge. You can also shred the chicken earlier in the day or even use pre-cooked chicken if you’re in a real rush.
