How to Make Slow Cooker Chicken Enchilada Casserole

Sauté the Aromatics

Heat oil in a skillet over medium heat. Add chopped onion, garlic, cumin, and salt. Cook for about 5 minutes, stirring often, until the onions soften and become lightly golden. This step builds a flavorful base for your casserole.

Build the Slow Cooker Base

Transfer the sautéed mixture into your slow cooker. Add enchilada sauce, sour cream, and a splash of water, then stir until smooth and well combined. Fold in the black beans so they are evenly coated in the sauce.

Add and Cook the Chicken

Place the chicken directly into the slow cooker, nestling it into the sauce. Cover and cook on high for 3–4 hours or on low for 6–7 hours until the chicken is fully cooked and tender.

Once done, shred the chicken directly in the pot using two forks so it absorbs all the flavorful sauce.

Add Tortillas and Cheese

Stir in the tortilla strips so they soften and soak up the sauce. Sprinkle shredded cheese evenly on top, then cover again and cook for about 30 minutes until the cheese is fully melted and creamy.

Finish and Serve

Top with fresh cilantro, sliced jalapeños, avocado, or extra sour cream. Serve warm, on its own or over rice for an even heartier meal.

Tips for Success

• Use chicken thighs for extra juicy and tender results
• Don’t skip sautéing the onions and garlic—it deepens the flavor
• Shred the chicken directly in the slow cooker to keep it moist
• Add tortillas near the end so they don’t become too mushy
• Let the casserole sit for a few minutes before serving to thicken

Equipment Needed

• Slow cooker
• Skillet for sautéing
• Cutting board and knife
• Two forks for shredding chicken
