Ingredients You Need

This recipe keeps things straightforward and delicious. Here’s all you need to create a hearty, cheesy enchilada casserole that everyone will love:

  • 3 large boneless, skinless chicken breasts
  • 2 cans of red enchilada sauce (1 large, 1 small for depth of flavor and just the right amount of sauce)
  • 2 cans of sliced black olives (one large for inside the casserole, one small for topping)
  • 1 large bag of shredded cheese (use Mexican blend, cheddar, or Monterey Jack—measure with your heart!)

Optional: A pack of 40 corn tortillas, sour cream for serving, and green onions or fresh cilantro for garnish.

Step-by-Step Instructions

1. Cook the Chicken in the Crock Pot

Start by placing your 3 large chicken breasts into the crock pot. Pour in both cans of enchilada sauce (one large and one small) to fully cover the chicken. Cook on high for 6 hours, or until the chicken is tender and shreds easily with a fork.

2. Shred the Chicken

Once cooked, remove the chicken and shred it using two forks. Place the shredded chicken back into the crock pot with the enchilada sauce, letting it soak up all that rich, spicy flavor.

3. Add the Tortillas and Mix

Use a pizza cutter to slice your corn tortillas into quarters (little triangles). Add them to the crock pot in batches, stirring to coat evenly in the saucy shredded chicken.

We recommend using the entire pack of 40 tortillas, especially if you like a thicker, more filling casserole. The tortillas soak up the sauce and become soft and flavorful—like enchiladas, but without all the rolling.

4. Mix in Cheese and Olives

Add in the large can of sliced olives and a generous handful of shredded cheese (about 2–3 cups or more if you like it extra cheesy). Stir everything together to make sure every tortilla triangle is coated and covered with cheesy, olive-specked goodness.

5. Top and Melt

Sprinkle even more shredded cheese across the top of the casserole, then scatter the small can of sliced olives over the cheese for a nice presentation. Cover the crock pot, and let everything cook until the cheese is completely melted—about 15–20 minutes more.

6. Serve and Enjoy

Serve your hot, gooey enchilada casserole straight from the crock pot with a dollop of sour cream on top. For extra flair, garnish with chopped green onions, fresh cilantro, or a few dashes of hot sauce.

Tips for the Best Crock Pot Chicken Enchilada Casserole

  • Use corn tortillas for the best texture. Flour tortillas can become gummy in the slow cooker.
  • Shred the cheese yourself from a block for better melting. Pre-shredded cheese often contains anti-caking agents.
  • Spice it up with diced jalapeños, green chiles, or a sprinkle of cayenne if you like heat.
  • Add beans or corn for more texture and color—just toss them in before the final cheese topping.

Make It Your Own

This casserole is highly customizable. Try these simple swaps or additions to make it even more satisfying:

  • Switch up the protein – Use cooked ground beef, turkey, or even leftover rotisserie chicken.
  • Go vegetarian – Skip the chicken and double up on beans, corn, and veggies.
  • Add cream cheese or sour cream – Stir in for an extra creamy texture.

Perfect for Meal Prep and Leftovers

This recipe makes a large batch, so expect plenty of leftovers—perfect for lunch the next day or freezing for later. To store:

  • Refrigerate in an airtight container for up to 4 days
  • Freeze in individual portions for up to 3 months
  • Reheat in the microwave or oven until warm and bubbly

The flavors actually deepen after a day, making it even tastier the next time around.

What to Serve with Enchilada Casserole

This dish is hearty on its own, but it pairs well with:

  • Mexican rice or cilantro lime rice
  • Refried or black beans
  • Guacamole and tortilla chips
  • Fresh garden salad with lime vinaigrette
