Preparation Steps
Season & Prep the Chicken
Begin by seasoning the chicken with salt, pepper, chili powder, cumin, garlic powder, and onion powder. This creates a bold flavor foundation that will infuse the entire casserole.
Slow Cook to Perfection
Place the seasoned chicken in the slow cooker. Top with chopped onions and diced green chiles, then pour the green enchilada sauce over everything. Cover and cook on LOW for 6–8 hours or HIGH for 3–4 hours, until the chicken is tender and easily shredded.
Shred & Add Creamy Goodness
Once cooked, shred the chicken directly in the slow cooker using two forks. Stir in sour cream and half of the grated cheddar cheese until the mixture is creamy and well-combined.
Assemble the Casserole
In the slow cooker, layer the shredded chicken mixture with cooked rice. You can alternate layers if you prefer, then sprinkle the remaining cheddar cheese on top.
Final Melt & Serve
Cover and cook on LOW for another 15 minutes until the cheese melts and becomes bubbly. Garnish with chopped green onions before serving for a fresh, vibrant touch.
Serving Suggestions
- Serve with warm tortillas for a taco-style meal.
- Pair with sliced avocado or guacamole for added creaminess.
