- Onion: One medium, sliced. You can use yellow or red onions, depending on your flavor preference.
- Fajita Seasoning: Approximately 2 tablespoons, either store-bought or homemade. If you’re in a pinch, taco seasoning works great too!
- Canned Tomatoes: One can (about 14 oz), diced with juices. You could use fresh tomatoes, but I love the convenience of canned.
- Cream of Chicken Soup: One can. This adds creaminess; however, you can substitute with a homemade roux if preferred.
- Cheddar Cheese: 2 cups, shredded. Monterey Jack can be a fun alternative for a milder taste.

How To Make Chicken Fajita Casserole
Making this casserole is super simple! Here’s how to do it step-by-step:
-
Preheat the Oven: Start by preheating your oven to 350°F (175°C). This way, it’s nice and hot when your casserole is ready to bake.
-
Cook Chicken: If you’re not using rotisserie chicken, cook the chicken breasts until they’re no longer pink. Shred or dice them when they cool down.
-
Sauté Veggies: In a large skillet, add a drizzle of oil and sauté the sliced bell peppers and onions until they are tender—about 5-7 minutes.
-
Combine Ingredients: In a large bowl, mix the cooked chicken, sautéed veggies, can of tomatoes, cream of chicken soup, and fajita seasoning. Stir until everything is well combined.
-
Layer the Casserole: In a greased baking dish, start by putting half of the crushed tortilla chips at the bottom. Pour half of the chicken mixture on top, followed by a layer of cheddar cheese. Repeat the layers, finishing with cheese on top.
-
Bake: Cover with aluminum foil and bake in the preheated oven for 25 minutes. Remove the foil and bake for an additional 10-15 minutes, until the cheese is bubbly and golden.
-
Serve and Enjoy: Let it cool for a couple of minutes before diving in. You can add fresh cilantro or avocado slices for an extra touch!
