• Taco seasoning (1 Tablespoon): Adds punchy, southwest spice and warms up the entire dish.
• Salt and black pepper (to taste): Essential for bringing out the flavors of every ingredient.
• Red enchilada sauce (two 10 oz cans): The luscious, savory base that soaks into everything and makes the casserole sing.
• Tomatoes with diced green chiles (one 10 oz can, drained): Adds zesty flavor and just the right hint of heat for balance.
• Corn tortillas (12 ounces, cut into wedges): Classic Mexican texture and sweetness, binding everything in the slow cooker.
• Shredded fiesta blend cheese (2 cups, divided): Melts into gooey, irresistible layers and brings every bite together.

How to Make Slow Cooker Chicken Enchilada Casserole

Step 1: Prepare the Slow Cooker

Start by giving your slow cooker some love with a generous coat of nonstick cooking spray. This tiny step pays off big time when you go to serve later, ensuring the luscious layers release easily (and making clean-up a cinch!).

Step 2: Layer the Chicken and Seasonings

Lay the chicken breasts across the bottom of your slow cooker. Sprinkle on the taco seasoning, a good pinch of salt, and plenty of black pepper to ensure every flavorful note reaches deep into the chicken as it cooks.

Step 3: Add Sauce and Tomatoes

Pour the two cans of red enchilada sauce and the drained tomatoes with green chiles evenly over the seasoned chicken. This creates a fiery, tangy bath that infuses each piece of chicken with all the character you expect from a Slow Cooker Chicken Enchilada Casserole.

Step 4: Slow Cook Until Tender

Cover the slow cooker and set it on low for 4 to 5 hours. Let the magic happen! This hands-off time is where the chicken turns tender and the flavors start to meld.

Step 5: Prep the Tortillas

While your slow cooker works its magic, cut your corn tortillas into rustic wedges. This ensures every bite in your casserole has that signature tortilla chew and structure.

Step 6: Shred the Chicken

Once the chicken is fully cooked and practically falls apart, grab two forks and shred it right in the slow cooker. Shredding lets the meat soak up every drop of flavorful sauce.

Step 7: Add Tortillas and Cheese

Stir in half of your tortilla wedges and half of the shredded cheese. This step creates delicious pockets of cheesy goodness and binds the base together beautifully.

Step 8: Layer and Top

Gently press the casserole mixture into an even layer. Arrange the remaining tortilla wedges over the top and sprinkle with the rest of the cheese. Each layer gets even cheesier and more inviting!

Step 9: Final Cooking

Re-cover your slow cooker and continue cooking for another 30 minutes. This gives the top layer a chance to soak up just enough sauce and ensures the cheese melts into an irresistible finish. Your Slow Cooker Chicken Enchilada Casserole is now ready to impress!

Make Ahead and Storage

Storing Leftovers

Freezing

This casserole is a freezer superstar! Pack cooled portions into freezer-safe containers or zip bags, label with the date, and freeze for up to 2 months. Just thaw overnight in the fridge before reheating, and you’ll have a homemade meal at the ready.

Reheating

FAQs

Can I use rotisserie chicken instead of raw chicken breasts?

Absolutely! If you’re short on time, shredded rotisserie chicken works well. Just reduce the initial cook time—add the chicken with the sauce and tortillas, and cook until heated through, about 1 to 2 hours on low.

Can I make this dish spicier?

Yes! For more heat, use medium or hot enchilada sauce, toss in some sliced jalapeños, or add a dash of cayenne to the seasoning mix. It’s easy to dial up the spice to suit your taste buds.

What if I only have flour tortillas?

You can substitute flour tortillas in a pinch, but note that the texture will be a bit softer and less traditional. Corn tortillas are preferred for that classic enchilada character, but don’t let that stop you from making the casserole with what you have!

Is it possible to add vegetables to the casserole?

Go for it! Add a layer of sautéed bell peppers, onions, corn, or even some black beans for extra color, nutrition, and heartiness. Just stir them in when you add the chicken and sauce.

Can I assemble the casserole ahead and cook later?

Yes, you can prepare everything the night before—arrange the slow cooker insert in the fridge overnight, then pop it into the heating unit and start cooking the next day. This is perfect for busy mornings or when you want dinner ready with zero effort!
