Why You’ll Love This White Chicken Enchilada Casserole

If you love creamy casseroles and Tex-Mex flavors, this recipe will win you over immediately. It saves time compared to traditional enchiladas but keeps all the flavor. Plus, it reheats beautifully, making it great for meal prep. It’s also easy to customize with what you have on hand, like swapping in rotisserie chicken or using flour tortillas instead of corn.

What Kind of Tortillas Should I Use?

Corn tortillas are traditional for enchiladas and they hold up well in layers, soaking up the sauce without getting mushy. If you prefer flour tortillas, they’ll create a slightly softer texture. Whichever you choose, warm them up before assembling so they layer easily and don’t crack.

Ingredients for the White Chicken Enchilada Casserole

Every ingredient here serves a purpose. From building that silky white sauce to loading the casserole with satisfying flavor, here’s what you need:

Cooked chicken – Tender shredded or chopped chicken forms the hearty base.
Green chiles – Adds a gentle kick and classic enchilada flavor.
Butter – Starts the roux for our creamy sauce.
All-purpose flour – Thickens the white sauce.
Chicken broth – Adds savory depth to the sauce.
Sour cream – Brings creaminess and a little tang.
Garlic powder – Adds a gentle savory note.
Salt & pepper – Simple seasonings that enhance the other flavors.
Shredded cheese – Use Monterey Jack or a Mexican blend for that melty topping.
Corn tortillas – Layer in for structure and flavor.

How To Make the White Chicken Enchilada Casserole

Step 1: Prep the Sauce

In a medium saucepan, melt the butter over medium heat. Whisk in the flour and cook for a minute to make a roux. Slowly whisk in the chicken broth until smooth and thickened. Remove from heat and stir in the sour cream, green chiles, garlic powder, salt, and pepper.

Step 2: Layer the Casserole

Preheat your oven to 375°F. Lightly grease a 9×13-inch baking dish. Spread a little of the sauce on the bottom. Add a layer of corn tortillas, followed by chicken, sauce, and shredded cheese. Repeat layers until everything is used up, ending with cheese on top.

Step 3: Bake Until Bubbly

Cover with foil and bake for 20 minutes. Uncover and bake for another 10-15 minutes until the cheese is golden and bubbling. Let it rest for 5-10 minutes before serving.

Serving and Storing This White Chicken Enchilada Casserole

This hearty casserole feeds about 6 to 8 people, depending on how generous your servings are. It’s filling, so you don’t need a lot on the side, but it pairs beautifully with fresh toppings or a crisp salad.

To store leftovers, let the casserole cool completely and refrigerate in an airtight container for up to 4 days. It also freezes well for up to 2 months. To reheat, bake covered at 350°F until warmed through or microwave individual portions.
