Green Chile Chicken Enchilada Casserole (Slow Cooker Recipe)

Shredded chicken combined with cream of chicken soup, canned green enchilada sauce and fire-roasted green chiles, finished with sour cream, sharp cheddar, and crisped corn tortillas and green onions—this Slow Cooker Chicken Enchilada Casserole is a family favorite.

I first made this casserole in 2015 and it quickly became a household staple. I often marinate the chicken in the sauce overnight right in the slow cooker insert, then set it to cook while we’re out for the day. When I return, the kitchen smells amazing. I shred the chicken, stir in the remaining ingredients, and finish it off with cheese and tortillas.

We serve it in bowls and top it how we like—sometimes with chips for scooping. These photos are from my original batch, served with a crunchy side; tortilla chips work perfectly if you don’t have specialty rolls.

Shortly after I shared this recipe it was featured on The Today Show Food website as a Slow Cooker Recipe Favorite.

Ingredients for Slow Cooker Enchilada Casserole

Scroll to the recipe card below for exact measurements and the printable recipe.

• Chicken breasts – Boneless, skinless breasts work best; they shred easily after slow cooking.
• Green enchilada sauce – Canned green enchilada sauce is convenient, or use salsa verde or homemade enchilada sauce if preferred.
• Cream of chicken soup – Adds creaminess and body to the sauce.
• Fire-roasted green chiles – Canned fire-roasted chiles add smoky flavor; jalapeños can be used for more heat.
• Green onion – Sliced and stirred into the filling, with extra for garnish.
• Sour cream – Use full-fat or reduced-fat to add creaminess; reserve some for serving if desired.
• Sharp cheddar cheese – Freshly grated sharp cheddar delivers the best flavor.
• Corn tortillas – Cut into 1″ x 2″ strips or tear into pieces so they absorb sauce and add texture.

• Optional for serving: tortilla chips, avocado, extra sour cream, cilantro, lime, or additional green onions.

How to Make This Crockpot Enchilada Casserole

This casserole comes together in a few straightforward steps.

First: Lay the chicken breasts in the bottom of a 6-quart slow cooker.

Second: Whisk together the green enchilada sauce, cream of chicken soup, and chopped fire-roasted chiles, then pour the mixture over the chicken.

Third: Cover and cook on LOW for about 8 hours, avoiding lifting the lid during cooking so the chicken stays tender and moist.

Fourth: Remove the cooked chicken and shred it. Return the shredded chicken to the slow cooker and stir in sliced green onions, sour cream, 1 cup of shredded cheddar, and the cut corn tortillas. Press the mixture down, top with the remaining cheese, cover, and cook on HIGH for one more hour to meld flavors and melt the cheese.

Fifth: Scoop into bowls or a serving dish and garnish as desired.

Store leftovers in an airtight container in the refrigerator for up to 4 days, or freeze for up to 3 months. Thaw overnight in the fridge and reheat in the oven for best texture.

FAQs

• Why is my enchilada casserole soggy? Corn tortillas can absorb too much moisture, which makes the casserole soggy.
• How do you prevent a soggy enchilada casserole? Lightly fry or bake tortillas briefly before layering, preheat your baking dish so tortillas crisp slightly on contact, or avoid pouring excess sauce directly into the pan so the tortillas aren’t sitting in liquid.
• Can I put frozen chicken in the crockpot? Yes, frozen chicken can be used but plan for additional cooking time and ensure it reaches a safe internal temperature.

Substitutions

Feel free to adapt the recipe to your preferences or dietary needs:

• Use salsa verde or tomatillo salsa if you don’t have green enchilada sauce.
• Swap corn tortillas for flour or gluten-free tortillas.
• Try Monterey Jack, Colby Jack, or a blend instead of sharp cheddar for a different flavor profile.

Tips & Tricks

• Lightly spray the slow cooker insert with cooking spray for easier cleanup.
• Use leftover or rotisserie chicken to save time—shred before freezing for quick meals.
• Garnish with fresh cilantro and a squeeze of lime for extra brightness.
• Grate your own cheese for the best flavor and texture.
• Add black olives, diced bell peppers, or red onion for extra flavor and color.
• Stir in cream cheese for an even richer filling if desired.
