Instructions
Add the diced onion to the bottom of the crockpot.
Place the chicken over the onion. Season with the taco seasoning, garlic powder, onion powder, paprika, salt, and pepper.
Pour the enchilada sauce over the chicken. Add the diced green chiles, drained black beans, and drained corn.
Cover and cook on low for 6 to 7 hours or high for 3 to 4 hours, until the chicken is tender and easily shreds.
Shred the chicken directly in the crockpot and stir everything together.
Add the tortilla pieces, 1 cup of shredded cheese, and optional sour cream. Stir until everything is evenly combined.
Sprinkle the remaining cheese over the top. Cover and cook for another 15 to 20 minutes, until the cheese is melted.
Serve with sour cream, avocado, cilantro, diced tomatoes, or crushed tortilla chips.
Tips for the Best Results
- To make shredding easier, use two forks to pull the chicken apart directly in the crockpot.
- For extra flavor, lightly toast your flour tortillas in a dry skillet before tearing them; it adds more depth.
- Don't overcook the chicken; it should be tender enough to shred easily but not mushy.
- Taste the sauce before adding the tortillas and cheese, and adjust seasonings like salt and pepper as needed.
- If you prefer a thicker sauce, you can remove about a cup of the liquid, mix with a tablespoon of cornstarch, then stir back into the crockpot.
Variations & Substitutions
- Swap chicken for 1 lb of ground turkey or beef, browning it before adding to the crockpot.
- For a vegetarian option, double the beans and corn, or add other veggies like bell peppers and zucchini.
- Kick up the heat by adding a diced jalapeño with the onions or a pinch of cayenne pepper with the seasonings.
- Make it dairy-free by using a plant-based cheese alternative and serving with a dollop of dairy-free sour cream or avocado.
- Instead of flour tortillas, you can use torn corn tortillas or even tortilla chips for an extra crunchy texture.
Storing Leftovers
Store any leftover enchilada casserole in an airtight container in the refrigerator for up to 3-4 days. For longer storage, freeze cooled portions in freezer-safe containers for up to 2-3 months.
Reheating
To reheat, individual portions can be microwaved on medium power in 60-second intervals until heated through. For a larger batch, warm in an oven-safe dish covered with foil at 325°F for 20-25 minutes, or until bubbling and hot, adding a splash of broth if it seems dry.
Frequently Asked Questions
Can I use different types of chicken?
Yes, you can use chicken tenders or even a mix of white and dark meat. Just ensure they are boneless and skinless for easy shredding.
What if I don't have enchilada sauce?
You can make a quick homemade version with tomato sauce, chili powder, cumin, garlic powder, and oregano, or try a different canned sauce like a mild salsa verde for a twist.
Is this dish spicy?
The recipe as written is mild, especially with a mild enchilada sauce. You can easily adjust the spice level by adding more green chiles, jalapeños, or a dash of hot sauce.
Can I prepare this ahead of time?
You can prep the onions and seasoning mix the night before. For the best texture, add the tortillas and final cheese during the last cooking stage, right before serving.
How do I prevent the tortillas from getting mushy?
Tearing the tortillas into smaller, bite-sized pieces and stirring them in only for the last 15-20 minutes helps them absorb the sauce without completely disintegrating.
