Crockpot Chicken Enchilada Casserole Ingredients

• Get ready to gather these simple staples!

For the Chicken

Boneless, Skinless Chicken Breasts – The main protein source; fresh or thawed frozen chicken works best for even cooking.
Taco Seasoning – Adds essential spice; store-bought is convenient, but homemade can offer a personalized flavor.
Salt and Black Pepper – Enhances overall taste; feel free to adjust according to your preference.

For the Sauce

Red Enchilada Sauce (2 cans, 10 oz each) – Serves as the base, bringing moisture and a kick of flavor; choose between mild or spicy based on your family’s taste.
Diced Tomatoes with Green Chiles (1 can, 10 oz, drained) – Infuses the casserole with tang and texture; be sure to drain well to avoid excess liquid.

For the Base

Corn Tortillas (12 oz, cut into wedges) – Acts as a structural base for the casserole; fresh tortillas are optimal, but stale ones hold up well too.

For the Cheese

Fiesta Blend Shredded Cheese (2 cups, divided) – Adds creaminess and flavor; reserve half for topping to avoid a rubbery texture.

Step‑by‑Step Instructions for Crockpot Chicken Enchilada Casserole

Step 1: Prepare the Slow Cooker
Begin by spraying the inside of your slow cooker with a nonstick cooking spray. This step ensures that your delicious Crockpot Chicken Enchilada Casserole won’t stick to the bottom, making it easier to serve and clean. Once prepped, set the slow cooker aside while you gather the main ingredients.

Step 2: Season the Chicken
Place the boneless, skinless chicken breasts evenly at the bottom of the slow cooker. Generously sprinkle the taco seasoning, salt, and black pepper over the chicken, ensuring an even distribution to infuse flavor during cooking. This will create a flavorful base for your casserole as it simmers in the crockpot.

Step 3: Add the Sauces
Pour the red enchilada sauce and the drained diced tomatoes with green chiles over the seasoned chicken. Gently stir to combine without disturbing the chicken too much. The sauce will add moisture and flavor to the Crockpot Chicken Enchilada Casserole, so make sure to cover the chicken completely with the sauce mixture before proceeding.

Step 4: Cook Low and Slow
Secure the lid on your slow cooker and set it to cook on low for 4 to 5 hours. This low and slow method will allow the chicken to become tender and easy to shred. While it cooks, a wonderful aroma will fill your kitchen, beckoning everyone to gather around the dinner table.

Step 5: Prepare the Tortillas
While your chicken is cooking, take this time to cut the corn tortillas into wedges. Aim for uniform pieces to ensure even distribution throughout the casserole. Once ready, set the tortilla wedges aside, ready to be mixed in later to add texture to your dish.

Step 6: Shred the Chicken
After cooking for the designated time, check that the chicken is cooked through and tender. Using two forks, shred the chicken directly in the slow cooker, mixing it into the sauce. Add in half of the cheese and the prepared tortilla wedges, gently folding everything together to combine these ingredients for a flavorful and hearty mixture.

Step 7: Layer with Tortillas and Cheese
Once thoroughly mixed, smooth the chicken and tortilla mixture into an even layer in the slow cooker. Add any remaining tortilla wedges on top of the mixture, followed by the remaining shredded cheese. This creates a delicious, cheesy topping that will melt and bubble beautifully during the final cooking phase.

Step 8: Final Cooking Phase
Cover the slow cooker once more and continue cooking on low for an additional 30 minutes. This step allows the cheese to melt perfectly, creating a delightful and gooey topping for your Crockpot Chicken Enchilada Casserole. Keep an eye on it and resist the urge to lift the lid, as this can prolong cooking time.

Step 9: Rest Before Serving
Once the cooking time has elapsed, turn off your slow cooker and allow the casserole to rest for about 10 minutes. This resting period lets the flavors meld together beautifully, making it easier to scoop out servings. Get ready to enjoy a warm, satisfying meal your family will love!

How to Store and Freeze Crockpot Chicken Enchilada Casserole

Fridge: Store leftovers in an airtight container for up to 4 days. The flavors actually improve after a night in the fridge, making them even more delicious!

Freezer: Wrap the casserole tightly in plastic wrap and then aluminum foil before placing it in the freezer. It’ll keep well for up to 3 months, retaining its tasty goodness.

Reheating: To enjoy your Crockpot Chicken Enchilada Casserole, thaw it overnight in the fridge. Reheat in the oven at 350°F for 20-25 minutes, or microwave individual portions for quick meals.

Expert Tips for Crockpot Chicken Enchilada Casserole

Thaw Chicken Properly: Always ensure chicken is fully thawed and patted dry before seasoning to avoid uneven cooking in your casserole.

Save the Cheese: Reserve half of the shredded cheese until the last 30 minutes to achieve that perfect gooey texture without it becoming rubbery.

Drain Canned Ingredients: Make sure to drain the diced tomatoes with green chiles thoroughly; excess liquid can result in a soupy Crockpot Chicken Enchilada Casserole.

Keep the Lid Closed: Avoid lifting the lid frequently during cooking as this can significantly prolong the cooking time, leading to less tender chicken.

Let It Rest: Allow the casserole to rest for about 10 minutes before serving; this helps flavors meld and makes it easier to scoop out portions.

Crockpot Chicken Enchilada Casserole Recipe FAQs

What kind of chicken should I use for the casserole?
I recommend using boneless, skinless chicken breasts for the best texture and flavor. Fresh or thawed frozen chicken works perfectly, ensuring even cooking and tender results. If you prefer a slightly juicier option, boneless skinless chicken thighs can be used as a delicious substitute!

How should I store leftovers?
Store leftovers in airtight containers in the fridge for up to 4 days. I always find that the flavors continue to meld and improve after a night in the fridge, making each bite even better the next day!

Can I freeze the casserole?
Absolutely! Wrap the casserole tightly in plastic wrap and then in aluminum foil to prevent freezer burn. It can be stored in the freezer for up to 3 months. When you’re ready to enjoy it, thaw overnight in the fridge before reheating to keep it moist and delicious.

Why is my casserole too soupy?
This usually happens when the canned diced tomatoes with green chiles aren’t drained thoroughly. To prevent this, ensure you drain the tomatoes well before adding them to the slow cooker. If you find it’s already soupy, you can mix in crushed tortilla chips to help absorb the extra liquid!

Can I adapt this recipe for dietary restrictions?
Definitely! You can easily swap regular cheese for a dairy-free alternative to make it lactose-free. If you’re looking for a healthier option, whole wheat tortillas can take the place of regular corn tortillas, and you can add beans or corn for extra fiber and flavor!

How do I reheat the casserole?
For perfectly reheated casserole, thaw it overnight in the fridge first. Then, preheat your oven to 350°F (175°C) and bake for 20-25 minutes until heated through. You can also microwave individual portions for a quicker option—about 2-3 minutes should do the trick!
