Step-by-Step Instructions

Step 1: Prepare the Base

Spray slow cooker insert with nonstick spray. Place chicken breasts in the bottom.

Step 2: Add Flavor Builders

Pour in enchilada sauce, black beans, corn, green chiles, diced onion, and spices. Stir slightly to coat chicken.

Step 3: Slow Cook

  • Cook on LOW for 6 hours or HIGH for 3–4 hours until chicken is fork-tender.

Step 4: Shred the Chicken

Remove chicken, shred with two forks, then return to the slow cooker.

Step 5: Assemble the Casserole

Stir in tortilla strips. Sprinkle cheese over the top, cover, and cook on LOW for another 20–30 minutes until cheese is melted and bubbly.

Common Mistakes to Avoid

  1. Overcooking tortillas – Add them near the end so they don’t become mushy.
  2. Too much liquid – Drain beans and corn well to avoid a watery casserole.
  3. Not shredding chicken fully – Large chunks make it harder for flavors to blend.
  4. Skipping seasoning – Taste before serving; enchilada sauce brands vary in saltiness.

Storing Tips for the Recipe

  • Refrigerate: Store leftovers in an airtight container for up to 4 days.
  • Freeze: Freeze in individual portions for up to 2 months. Thaw overnight in the fridge before reheating.
