Step-by-Step Instructions

1. Heat avocado oil in a skillet over medium heat. Add diced onion, minced garlic, cumin, and salt. Sauté 5 minutes until softened and fragrant.
2. Transfer onion mixture to a 6-quart slow cooker. Stir in enchilada sauce, sour cream, and 1/4 cup water. Fold in drained black beans until coated.
3. Nestle chicken thighs into the sauce. Cover and cook on high 3-4 hours or low 6-7 hours, until chicken shreds easily (internal temp 165°F).
4. Shred chicken directly in the pot using two forks. Stir well to combine.
5. Cut corn tortillas into 1-inch strips. Add strips to the pot and stir. Top with 1 cup cheese and half the olives.
6. Sprinkle remaining 1 cup cheese and olives on top. Cover and cook on low 30-40 minutes until cheese melts and bubbles.
7. Scoop into bowls. Garnish with jalapeños, cilantro, avocado, and extra sour cream. Serve over cilantro lime rice if desired.

For Instant Pot: Sauté onions in pot, add remaining ingredients through step 3. High pressure 20 minutes, natural release 10 minutes. Shred, add tortillas and cheese, high pressure 5 minutes, quick release.

Frequently Asked Questions

Can I use raw chicken in the slow cooker?
Yes, raw boneless chicken works perfectly here. It cooks fully and infuses flavor into the sauce.

Corn tortillas or flour?
Corn holds shape best and adds authentic texture. Flour softens more but works in a pinch.

What if I don’t have 6 hours?
High setting cuts time in half. Rotisserie chicken skips initial cook entirely.

Make it ahead?
Assemble through step 3, refrigerate overnight, then finish steps 4-7.

Vegetarian version?
Replace chicken with mushrooms, zucchini, or double beans.

Freezer-friendly?
Yes, portion and freeze post-cooking. Thaw overnight before reheating.
