Chicken Tortilla Casserole is comfort food to the max. Made with chicken, corn tortillas, and a whole lotta cheese, your family will be begging you to make this weekly! I make my own cream of celery sauce from scratch (don’t worry, it’s fast) and trust me, it beats anything out of a can. You’ll get real flavor, better texture, and bonus points for using up leftover chicken. Let’s do this.

Ingredient Notes + Variations
This chicken tortilla casserole layers a homemade cream sauce, shredded chicken, melty cheese, and corn tortillas. The sauce is simple to make but brings big flavor with pantry staples and a few Tex-Mex touches.
- Corn tortillas – White or yellow works. Tear them up instead of slicing to keep it rustic and help them soak up the sauce.
- Shredded chicken – Here’s where Crockpot Shredded Chicken for Meal Prep shines!! Didn’t think ahead? No worries… rotisserie chicken works too.
- Cumin + oregano – Warm, earthy, and necessary.
Pro Tip: Prefer to skip the homemade soup? Swap in 2 cans of cream of celery soup mixed with 2 cans of milk. Still add sour cream, cumin, oregano, and extra salt.

How to Make Chicken Tortilla Casserole
This recipe comes together in three parts: make the sauce, layer everything in a casserole dish, then bake. It’s straightforward and fast once the sauce is done. For full recipe details, including ingredients and measurements, see the recipe card down below.
Step 1: Preheat Oven + Prep Pan
Preheat oven to 350° F. Spray a 9×13 casserole dish with nonstick cooking spray. Set aside for later.
Step 2: Make the Sauce (Sauté Onion + Celery)

melt butter, add diced onion + celery

add garlic + sauté

stir in spices, flour + continue to cook
Pro Tip: I find that corn tortillas need a lot of salt so I add another teaspoon to the sauce. Feel free to omit and allow for everyone to salt the finished dish as needed.
3. Assemble the Casserole

add a bit of the sauce to bottom of pan

place a layer of torn tortillas into the pan

add a layer of shredded chicken

cover with a layer of the creamy sauce

add a layer of shredded cheese

repeat these layers, ending with shredded cheese
4. Bake + Rest

bake until hot + cheese is bubbly

let casserole rest for 5-10 minutes
Tips for Success
- Tear, don’t slice, your tortillas for better texture.
- Use room temp sour cream so it blends in smoothly.
- Don’t skimp on salt, especially in the sauce.
- Let the casserole rest so it sets up a bit before serving.
- Garnish! Fresh toppings make it pop (avocado, cilantro, green onion, tomatoes).

Enjoy the flavors of Tex-Mex cuisine with this Chicken Tortilla Casserole, without spending hours in the kitchen! This is a good casserole that the whole family will love! Have a great day, friends! 🙂

My family loved this casserole. I will sure make this once a week. I served with rice and beans and salsa. But I will make with salads next time. Thank you for the recipe.
I’m not good on sour cream mixture so I just sautéed the veggies and whisked a little flour then added a little chicken broth to help thickened. It was great. Like I said I will make again.
