Chicken Fajita Casserole is my answer whenever I need an easy family dinner that brings all the vibrant flavors of fajitas into one bubbly baked dish. Layers of juicy chicken mix with colorful peppers and onions under a blanket of melted cheddar for a comforting meal that is perfect for busy nights or sharing with friends.
I first made this for a birthday movie night since we wanted something everyone could dig into together. Now it is my go-to for any gathering because it always disappears so fast.
Ingredients
- Shredded chicken: brings the hearty base and works best if precooked from rotisserie or poached at home
- Olive oil: helps soften and bring out the sweetness in the bell peppers and onions choose extra virgin for more flavor
- Green and red bell peppers: add color crunch and a mild sweetness look for firm glossy peppers
- Yellow onion: offers sweetness and depth of flavor slice thinly for best texture
- Fajita seasoning mix: delivers the classic zesty Mexican flavor with chili powder cumin and garlic you can use your own blend
- Salt and black pepper: boost all the other flavors a small pinch goes a long way
- Salsa: adds tangy moisture and even more spice chunky or smooth both work
- Shredded cheddar cheese: melts beautifully and turns golden pick a sharp cheddar for extra punch
- Fresh cilantro: adds a bright herbal note and beautiful color
Step-by-Step Instructions
- Prep and Sauté the Veggies:
- Add olive oil to a hot pan and toss in sliced bell peppers and onion with fajita seasoning salt and black pepper. Let them cook slowly for around eight minutes stirring often. You want them soft and fragrant with a lightly caramelized edge. This layering of vegetables with spices gives your casserole a deep base of flavor that tastes like true fajitas.
- Layer the Casserole:
- Place all your shredded chicken in a single even layer at the bottom of a casserole dish. Pour your favorite salsa over the chicken making sure it is spread out evenly so every bite has some tangy kick.
- Build the Flavor Layers:
- As soon as your veggies are soft scoop them over the chicken and salsa. Spread them right to the corners so you get color and texture in every slice.
- Top With Cheese and Bake:
- Sprinkle the shredded cheddar cheese evenly over everything. This will melt in the oven and form a beautiful golden topping that holds all those layers together.
- Bake the Casserole:
- Put the dish in a preheated oven at three seventy five degrees. Bake for twenty minutes or until the cheese bubbles and starts turning a light brown.
- Finish and Garnish:
- Carefully remove from the oven and let it cool for a moment. Finish by scattering fresh chopped cilantro over the top for a bright pop of flavor before serving.

One of my favorite quirks is watching my kids sneak seconds for those charred edges of melted cheddar that hide in the corners. I also love using homemade fajita seasoning for a fresher punch and always toss in extra cilantro on top.
Storage Tips
Leftover chicken fajita casserole stores well in an airtight container for up to four days in the fridge. To freeze portion individual servings into freezer bags or small dishes so you can reheat just what you need. Reheat in the oven or microwave until piping hot. I like adding a sprinkle of fresh cheese on top before reheating to freshen the flavor.
Ingredient Substitutions
This casserole is really flexible if you do not have cheddar use Monterey Jack or pepper jack for a bit more kick. For the salsa a chunky pico de gallo or even a can of fire roasted tomatoes can work if you are in a pinch. Substitute rotisserie turkey or even cooked pork for the chicken if you want a change.
Serving Suggestions
We often serve this casserole with warm tortillas on the side for scooping or wrapping. It is also great on top of Mexican rice or tucked into lettuce cups for a lighter twist. Top with sour cream or sliced jalapenos for an extra layer of fun.
