Chicken Enchilada Casserole Recipe

This creamy, cheesy White Chicken Enchilada Casserole is made with tender shredded chicken, mild green chiles, and a rich homemade sour cream sauce, ready in about 45 minutes. The hero moment is pulling the bubbling, golden dish from the oven and seeing the white sauce simmering around the edges. I love this recipe because it delivers all the flavor of traditional enchiladas without the tedious rolling.

Why This Classic Works

I used to make white enchiladas using condensed cream of chicken soup, and while it was convenient, the flavor was always a bit one-note and overly salty. What makes this version different is the simple homemade white sauce made from a roux, chicken broth, and sour cream. It takes only five minutes longer to make but transforms the dish into something that tastes like it came from a quality Mexican restaurant.

Another lesson I learned the hard way is about the tortillas. I once tried this with corn tortillas thinking it would be more authentic, but they tended to disintegrate into mush under the heavy cream sauce. Soft flour tortillas are the secret here—they soak up just enough of the savory sauce to become dumpling-like and tender while still holding their structure in the casserole.

White Chicken Enchilada Casserole Ingredients

• 3 cups cooked chicken, shredded (rotisserie chicken works perfectly)
• 10 soft flour tortillas (taco size), cut in half
• 3 cups Monterey Jack cheese, freshly shredded
• 3 tbsp unsalted butter
• 3 tbsp all-purpose flour
• 2 cups chicken broth
• 1 cup sour cream
• 1 can (4 oz) diced green chiles, undrained
• 1 tsp ground cumin
• ½ tsp garlic powder
• ½ tsp onion powder
• Salt and black pepper to taste
• Fresh cilantro for garnish (optional)

How To Make White Chicken Enchilada Casserole

1. Preheat and Prep: Preheat your oven to 350°F (175°C). Lightly grease a 9×13-inch baking dish with cooking spray or butter. Have your shredded chicken and halved tortillas ready to go.
2. Start the Sauce: In a medium saucepan over medium heat, melt the butter. Whisk in the flour and cook for about 1 minute until bubbly and pale golden. This removes the raw flour taste.
3. Thicken the Broth: Gradually pour in the chicken broth while whisking constantly to prevent lumps. Simmer for 3-4 minutes until the sauce thickens enough to coat the back of a spoon.
4. Finish the Sauce: Remove the pan from the heat. Stir in the sour cream, diced green chiles (with their liquid), cumin, garlic powder, and onion powder until smooth. Season with salt and pepper to taste.
5. Build the Layers: Spread about ½ cup of the sauce on the bottom of the baking dish. Arrange a layer of tortilla halves over the sauce. Top with half of the shredded chicken and 1 cup of cheese. Pour about ⅓ of the remaining sauce over this layer.
6. Repeat and Bake: Repeat with another layer of tortillas, the remaining chicken, another cup of cheese, and more sauce. Top with the final layer of tortillas, the rest of the sauce, and the remaining 1 cup of cheese. Bake for 20-25 minutes until the cheese is melted and the sauce is bubbly.

Recipe Tips

• Shred your own cheese: Pre-shredded cheese is coated in anti-caking agents that prevent it from melting smoothly. For that gooey, restaurant-style stretch, buy a block of Monterey Jack and grate it yourself.
• Don’t boil the sour cream: When making the sauce, always remove the pan from the heat before stirring in the sour cream. If you boil the sauce after adding the dairy, it can curdle and separate.
• Let it rest: It is tempting to dig in immediately, but letting the casserole sit for 10 minutes after baking allows the sauce to set slightly, making it much easier to cut into neat squares.
• Spice it up: If you prefer a kick, swap the mild green chiles for diced jalapeños or use Pepper Jack cheese instead of Monterey Jack.

What To Serve With White Chicken Enchilada Casserole

Since this dish is rich and creamy, I like to serve it with something acidic or fresh to cut through the heaviness. A crisp green salad with a lime vinaigrette or a simple side of Mexican red rice works beautifully. You can also serve black beans or pinto beans on the side for extra protein and fiber.

How To Store

Store leftovers in an airtight container in the refrigerator for up to 3-4 days. You can also freeze the unbaked casserole; just cover it tightly with plastic wrap and foil, and freeze for up to 3 months. Thaw overnight in the fridge before baking as directed.

FAQs

Can I use corn tortillas instead?
You can, but the texture will change significantly. Corn tortillas tend to soften more rapidly in the white sauce and may break apart. If you use them, briefly fry them in oil first to help them hold their shape.

Can I make this ahead of time?
Yes, you can assemble the entire casserole up to 24 hours in advance. Keep it covered in the fridge, and you may need to add 5-10 minutes to the baking time since it will be going into the oven cold.

Is the sauce spicy?
Not at all. The canned green chiles add a mild, tangy flavor without significant heat. It is a very family-friendly dish, but you can add cayenne pepper if you want heat.
