Ingredients
- 1/4 cup butter

- 1 cup onion, finely diced (about 1 small)
- 2 cloves garlic, minced
- 1 tsp salt (or to taste)
- 1/4 tsp black pepper (or to taste)
- 1/4 cup flour
- 1 1/2 cups chicken broth
- 1 1/2 cups whole milk
- 1 tsp ground cumin
- 1/2 tsp oregano
- 1/3 cup sour cream (room temperature)

- 20 corn tortillas (yellow or white, ripped into pieces)
- 4 cups shredded chicken (Rotisserie chicken works great!)

Preparing the Casserole Base

Sauté Vegetables
In a large skillet over medium-high heat, melt the butter. Add the finely diced onion and celery, sautéing them for about 8-10 minutes until they become translucent and softened. The aroma in your kitchen will be so inviting at this stage!
Incorporate Garlic and Seasonings
Add the minced garlic to the skillet and cook for an additional 1-2 minutes. Season with salt, black pepper, cumin, and oregano to enhance the flavors. This step adds warmth and depth to your casserole.
Create the Cream Sauce
Sprinkle the flour into the skillet, stirring for about 2-3 minutes. Gradually whisk in the chicken broth and whole milk, bringing the mixture to a low boil until it thickens. Turn off the heat and stir in the room temperature sour cream. This creamy sauce is what makes your Chicken Tortilla Casserole stand out!
Layering the Casserole
Start with a Sauce Layer
Pour a bit of the thick cream sauce into the bottom of a 9×13 casserole dish, spreading it evenly. This layer sets the stage for all the deliciousness to come.
Add Tortillas
Place a layer of the ripped corn tortillas directly over the sauce, creating a comforting foundation for your casserole.
Add Shredded Chicken
Layer the shredded chicken evenly over the tortillas. This is where all that tender, juicy chicken goodness comes into play.
Cover with Cream Sauce
Drizzle a layer of the cream sauce over the chicken, ensuring to cover it completely. Each bite should be creamy and flavorful.
Add Cheese
Sprinkle a generous layer of shredded Colby cheese over the sauce. Can you already taste the melty cheese?
Repeat Layers
Continue layering the tortillas, chicken, cream sauce, and cheese until all ingredients are used, ending with a final layer of cheese on top. This ensures a spectacular cheesy crust that everyone will love.
Baking the Casserole
Bake to Perfection
Preheat your oven to 350°F. Bake the casserole for 30-35 minutes, or until hot and bubbly. Patience will be your friend here, and the wait will be worth it!
Allow to Rest
Remove from the oven and let it sit for 5-10 minutes before serving to allow the flavors to meld. This resting period helps it set, ensuring better slices.
Serving Suggestions
Serve the Chicken Tortilla Casserole garnished with sour cream, avocado slices, cilantro, and diced green or red onion for added freshness and flavor. These little touches make all the difference!

- Use Rotisserie Chicken: This will save time and add fantastic flavor.
- Customize the Seasoning: Feel free to adjust spices according to your taste preferences. Mixing it up keeps it interesting!
