Ingredients
-
2 to 3 boneless, skinless chicken breasts (about 450–680 g)
-
1 tablespoon taco seasoning
-
Salt and black pepper, to taste
-
2 cans (10 oz each / 284 g) red enchilada sauce
-
1 can (10 oz / 284 g) diced tomatoes with green chiles, drained
-
12 oz (340 g) corn tortillas, cut into wedges
-
2 cups (200 g) shredded fiesta blend cheese, divided
Instructions
-
Spray your slow cooker liner with nonstick cooking spray to prevent sticking.
-
Place the chicken breasts in the bottom of the slow cooker. Season with taco seasoning, salt, and black pepper.
-
Pour both cans of enchilada sauce and the drained tomatoes with green chiles evenly over the chicken.
-
Cover and cook on low for 4–5 hours, until the chicken is tender and fully cooked.
-
While the chicken cooks, cut the corn tortillas into wedges.
-
Once cooked, shred the chicken directly in the slow cooker using two forks.
-
Stir in the tortilla wedges and half of the shredded cheese, ensuring everything is well coated.
-
Press the mixture evenly into the slow cooker. Top with the remaining tortilla wedges and cheese.
-
Re-cover and cook on low for 30 more minutes, or until the cheese is melted and bubbly.
Notes
Spray the liner to prevent sticking — melted cheese can cling to the sides.
Cooking on low enhances flavor development.
If the sauce is too thick, add a few tablespoons of broth or water.
Save an extra tortilla or cheese for an additional layer if desired.
The casserole may look soupy at first, but it thickens as it rests.
Store leftovers in the fridge for 3–4 days or freeze for up to 2 months.

Cooking Tips & Tricks
-
Don’t skip spraying — the cheese melts into nooks, and it can stick otherwise.
-
Use a low setting rather than a high one; the slow buildup gives a deeper flavor.
-
If your enchilada sauce is extra thick, stir in a few tablespoons of water or broth to help everything mingle.
-
Save a tortilla or two (or extra cheese) in case you want to layer more at the end.
-
The tortillas soak into the juices — don’t worry if it looks soupy at first. As it finishes, it sets up nicely.
A Little Backstory
Years ago, when my schedule was absolutely bonkers and I still tried to make something homemade for dinner, this recipe was born. One evening, I tossed all the ingredients into the crockpot, rushed out to run errands, and came back to a kitchen smelling like a taqueria. My husband’s eyes lit up, the kids gobbled it up, and I knew I had a winner. Ever since, this casserole has been my fallback for nights when I want dinner ready but can’t be.
What to Serve With It
This casserole is rich and filling on its own, but pairing it with a few lighter sides gives balance:
-
A crisp green salad with lime vinaigrette or simple romaine + cherry tomatoes
-
Sliced avocado or guacamole for creaminess
-
A side of steamed corn or black beans
-
Cilantro-lime rice, if you want extra carbs
-
A squeeze of fresh lime and chopped cilantro on top gives brightness
How to Store & Reheat
-
Let leftovers cool to room temperature before covering.
-
Store in airtight containers in the fridge for up to 3–4 days.
-
To reheat, microwave individual servings for 1–2 minutes, or reheat in a 350 °F oven (175 °C) for about 15 minutes (cover with foil if cheese starts browning too fast).
-
You can also freeze portions in freezer‑safe containers for up to 2 months. Thaw overnight in the fridge before reheating.
-
If the casserole seems dry when reheated, add a splash of enchilada sauce, broth, or even milk to help it moisten up.
FAQs
Can I use shredded chicken from the store?
Yes — if you already have cooked, shredded chicken, reduce the initial slow cook time. Just layer it with sauce, tomatoes, tortillas, and cheese, then finish with the final 30 minutes.
Is it possible to make this into individual portions?
Absolutely! Use small slow cookers or large, deep ramekins. Just adjust cooking time slightly (they may finish faster).
Can I swap flour tortillas for corn?
You can, though corn tortillas absorb sauce better and give a more authentic texture. If using flour, reduce how much you use to avoid mushiness.
How can I make it spicier (or milder)?
For more heat, use enchilada sauce labeled “hot” or add chopped jalapeños. To mellow it, stick with mild sauce and skip extra peppers.
This slow cooker chicken enchilada casserole is the kind of dish that feels fancy but really isn’t. It gives you the bold flavors of a Tex‑Mex casserole, delivers the convenience of crockpot enchiladas, and leaves you feeling like a dinner rockstar. Try it tonight—you may just find your new favorite go-to easy dinner.
