What Kind of Tortillas Work Best for White Chicken Enchilada Casserole?

For this recipe, soft flour tortillas create the best layers—they soak up the creamy sauce but still hold their shape after baking. Corn tortillas can be used if you prefer a more traditional flavor, but flour tortillas are more forgiving and kid-friendly in a casserole like this.

Ingredients for the White Chicken Enchilada Casserole

Each ingredient in this casserole brings something special—let’s break down what you need and why:

• Shredded cooked chicken (3 cups): The hearty base for your casserole—rotisserie chicken makes this step fast and easy.
• Flour tortillas (8 large, burrito-size): These provide the perfect soft layers between chicken and sauce.
• Monterey Jack cheese (2 cups, shredded): Melts smoothly for a creamy interior.
• Cheddar cheese (1 cup, shredded): Adds color and extra cheesy flavor on top.
• Butter (4 tablespoons): Used to sauté the aromatics and build the white sauce.
• Yellow onion (1 medium, finely diced): Brings sweetness and depth to the sauce.
• All-purpose flour (1/4 cup): Thickens the creamy white sauce.
• Chicken broth (2 cups): The liquid base for your sauce; opt for low-sodium if desired.
• Sour cream (1 cup, plus extra for topping): The key to a tangy, ultra-creamy sauce.
• Canned mild green chiles (2 cans, 4 oz each, drained): Add gentle heat and classic enchilada flavor.
• Garlic powder (1 teaspoon): Easy way to infuse flavor into the sauce.
• Cumin (1 teaspoon): Adds earthy warmth.
• Salt & black pepper (to taste): For seasoning.
• Fresh cilantro and green onions (for garnish): Brighten up the finished dish.
• Diced tomatoes (optional, for garnish): Adds fresh pop and color.

Each of these ingredients contributes to making a rich, flavorful, and perfectly layered casserole that’s as comforting as it is crowd-pleasing.

How To Make the White Chicken Enchilada Casserole

Step 1: Prepare Your Ingredients

Preheat your oven to 375°F (190°C). Grease a 9×13-inch baking dish. Shred the cooked chicken if you haven’t already, and have your tortillas, cheeses, and other ingredients ready to go.

---

Step 2: Make the Creamy White Sauce

In a large skillet over medium heat, melt the butter. Add the diced onion and sauté until soft and translucent, about 3–4 minutes. Sprinkle in the flour and cook, whisking constantly, for 1 minute to eliminate the raw flour taste. Gradually whisk in the chicken broth, stirring until the sauce is smooth and starts to thicken (about 3–4 minutes). Remove the pan from heat and stir in the sour cream, green chiles, garlic powder, cumin, salt, and pepper until fully combined.

---

Step 3: Assemble the Layers

Spread about 1/2 cup of the white sauce on the bottom of your prepared baking dish. Layer 2 tortillas over the sauce, tearing to fit if needed. Top with 1/3 of the shredded chicken, 1/3 of the Monterey Jack cheese, and 1/3 of the white sauce. Repeat this layering twice more (tortillas, chicken, cheese, sauce), ending with the last 2 tortillas on top.

---

Step 4: Top and Bake

Spread any remaining sauce evenly over the top layer of tortillas. Sprinkle with all of the shredded cheddar cheese. Cover the baking dish with foil and bake for 20 minutes. Remove the foil and bake an additional 10–15 minutes, until the cheese is golden and bubbling.

---

Step 5: Garnish and Serve

Let the casserole cool for at least 10 minutes before slicing. Garnish with dollops of sour cream, fresh cilantro, green onions, and diced tomatoes if desired. Slice into 8 hearty squares and serve warm.
