Step by Step Instructions for Baked Chicken Fajita Casserole
Heat Your Oven
Get your oven preheating to 375°F (190°C) so it reaches the right temperature by the time your casserole is ready to go in.
Mix Your Filling
In a large bowl, combine these ingredients together:
Stir everything until the spices coat all the ingredients evenly and nothing sits at the bottom of the bowl.
Layer Your Base
Spread half of 8 tortillas cut into strips across the bottom of your baking dish in an even layer.
Add The Chicken Mixture
Spoon the filling mixture from your bowl right onto those tortilla strips, spreading it out so each part of the base gets covered.
Add First Layer Of Cheese
Sprinkle 1 cup of shredded cheese over the chicken mixture, distributing it across the top.
Top With Remaining Tortillas
Arrange the rest of your tortilla strips on top of the cheese layer.
Finish With Cheese
Add the remaining 1 cup of shredded cheese across the top so the casserole gets a nice golden finish.
Bake The Casserole
Put the dish in your preheated oven and bake for 25 to 30 minutes until the cheese melts and starts bubbling at the edges.
Cool Before Serving
Take the casserole out of the oven and let it sit for a few minutes before plating up, which gives everything a chance to set.

FAQs
Can I use corn tortillas instead of flour tortillas?
Yes, corn tortillas work great in this casserole. They hold up well during baking and give the dish a different texture. Just break them into strips the same size as you would with flour tortillas.
What if I don’t have fresh bell peppers?
Frozen bell peppers are a good substitute. They’re already prepped and work just as well in a casserole. There’s no need to thaw them first-just add them straight from the freezer.
Can I make this with ground chicken instead of shredded chicken?
Ground chicken is a fine swap. Brown it in a skillet with the seasonings first, then mix it with the other ingredients before layering. The cooking time stays the same.
Should I drain the canned tomatoes and corn?
Drain the corn completely so it doesn’t make the casserole watery. For tomatoes, drain them halfway-this keeps the dish moist without being soggy.
What cheese melts best for this dish?
Cheddar or Mexican blend cheese work best here. They melt smoothly and create that bubbly top. A mix of both gives nice flavor.
Can I assemble this the night before?
Yes, prepare it completely, cover it with foil, and refrigerate overnight. Bake it straight from the fridge, adding about 5 extra minutes to the baking time.

Description
Your baked chicken fajita casserole brings all the flavors you love from a sizzling skillet straight into one easy dish that feeds a crowd. Tender chicken, peppers, and onions layer with tortillas and cheese so everything bakes together into something warm and satisfying that your family will ask for again and again.
Ingredients
Protein and vegetables:
- 2 cups cooked chicken, shredded
- 1 bell pepper, sliced
- 1 onion, sliced
- 1 can black beans, drained and rinsed
- 1 can diced tomatoes
- 1 cup corn
Seasonings and spices:
- 1 tablespoon chili powder
- 1 teaspoon cumin
- salt and pepper to taste
Binding and structure:
- 2 cups shredded cheese
- 8 tortillas, cut into strips
Instructions
- Heat your oven to 375°F before assembling anything else.
- Combine your 2 cups shredded chicken with 1 sliced bell pepper, 1 sliced onion, 1 drained can of black beans, 1 can diced tomatoes, 1 cup corn, 1 tablespoon chili powder, 1 teaspoon cumin, salt, and pepper in a large bowl.
- Spread half of your 8 tortillas cut into strips across the bottom of your baking dish.
- Pour your chicken mixture evenly over the tortilla layer in your dish.
- Scatter 1 cup of your 2 cups shredded cheese across the chicken filling.
- Layer the remaining tortilla strips on top and finish with the final 1 cup cheese.
- Slide your casserole into the 375°F oven for 25 to 30 minutes until the cheese bubbles and browns slightly on top.
- Remove from heat and let your casserole rest for 3 to 5 minutes so it sets before you serve it.
Notes
- Shred your chicken into bite-sized pieces rather than leaving it in chunks so it distributes evenly throughout the casserole and makes each bite more enjoyable.
- Cut your tortillas into strips before layering, as this prevents them from bunching up and helps them absorb the flavors from the chicken mixture better than whole tortillas would.
- If your casserole seems dry while baking, pour a bit of chicken broth over the chicken mixture before adding the cheese layers to keep everything moist and tender.
- For a vegetarian version, replace the chicken with an extra can of black beans and add diced zucchini or mushrooms to keep the casserole hearty and filling.
