How to Make White Chicken Enchilada Casserole Recipe
Step 1: Prepare the Chicken Mixture
Begin by combining your cooked shredded chicken with 1 1/2 cups of Monterey Jack cheese, diced green chiles, and all the spices—garlic powder, onion powder, cumin, salt, and black pepper—in a large bowl. This mixture becomes the flavorful core of your casserole, with each seasoning working in harmony to lift the mild chicken flavors into something truly memorable.
Step 2: Make the White Sauce
In a saucepan over medium heat, melt the butter and whisk in the flour to create a roux. Cook it for about a minute to get rid of the raw flour taste. Then, slowly pour in the chicken broth and milk while continuously whisking. This step creates a silky white sauce that thickens beautifully in just a few minutes. Once thickened, remove from heat and stir in the sour cream for a smooth, tangy finish that’s key to this recipe’s creaminess.
Step 3: Layer the Casserole
Lightly grease a 9×13-inch baking dish and begin assembling by spreading a thin layer of sour cream sauce on the bottom. Next, layer 4 tortillas to cover the base, followed by half of the chicken mixture and then more sauce. Repeat these layers with the remaining tortillas, chicken mixture, and sauce to build a rich, creamy structure that will bake into cheesy perfection.
Step 4: Add Cheese and Bake
Sprinkle the remaining 1/2 cup of shredded Monterey Jack cheese evenly across the top. The cheese will melt and form a golden, bubbling crust during baking. Bake the casserole uncovered at 375°F (190°C) for 25 to 30 minutes until the edges bubble and the top is beautifully browned. After baking, let it rest for 5 minutes to set up before serving.
How to Serve White Chicken Enchilada Casserole Recipe

Garnishes
Fresh garnishes like chopped cilantro or sliced green onions add a burst of color and a fresh herbal note that complements the richness of the casserole. A dollop of sour cream or a squeeze of lime juice can brighten each bite and give it that restaurant-quality finish.
Side Dishes
This hearty casserole pairs wonderfully with crisp green salads or Mexican-style street corn for a vibrant contrast in textures and flavors. A light avocado salad or black bean and corn salsa also be excellent for rounding out the meal without overshadowing the star dish.
Creative Ways to Present
For a casual gathering, serve this casserole family-style straight from the baking dish so everyone can dig in and serve themselves. Alternatively, for a more polished presentation, plate individual portions and add a small side of pickled jalapeños or a drizzle of homemade salsa verde for color and a zingy kick.
Make Ahead and Storage
Storing Leftovers
Leftover White Chicken Enchilada Casserole Recipe keeps well when stored in an airtight container in the refrigerator for up to 3 days. The flavors deepen overnight, making it just as delicious the next day.
Freezing
You can freeze the casserole either before baking or after it has cooled completely. Wrap it tightly in foil and plastic wrap or use a freezer-safe container to prevent freezer burn. It will keep well for up to 2 months, perfect for meal prep or unexpected guests.
Reheating
Reheat leftovers gently in the oven at 350°F (175°C) until warmed through to maintain that lovely melty texture. Microwaving works too but can sometimes alter the sauce’s consistency, so cover and heat in short bursts to avoid drying out.
FAQs
Can I use rotisserie chicken for this recipe?
Absolutely! Rotisserie chicken is a fantastic shortcut that adds flavor and saves time without compromising the deliciousness of your White Chicken Enchilada Casserole Recipe.

How long does the casserole take to bake?
It bakes uncovered at 375°F (190°C) for about 25 to 30 minutes, just enough time for it to bubble and form that gorgeous golden crust on top.
