How to Make Slow-Cooker Taco Casserole

1. Spray the inside of a 3½ or 4-quart slow cooker with nonstick cooking spray.
2. In a large skillet over medium-high heat, brown ground beef with chopped onion and minced garlic for 8–10 minutes until fully cooked, stirring frequently. Drain excess fat. Stir in taco seasoning mix, salt, and pepper.
3. Layer 3 tortillas in the bottom of the slow cooker. Spread half of the beef mixture on top, followed by ½ cup chicken broth, ½ cup tomato sauce, and the entire can of enchilada sauce. Sprinkle with ½ cup shredded Cheddar cheese.
4. Add 3 more tortillas, then top with beans, corn, chopped green chiles, half of the chopped olives, and ½ cup shredded cheese.
5. Finish with the remaining 3 tortillas, remaining ½ cup cheese, and remaining olives.
6. Cook on high for 2.5–3 hours or low for 6–7 hours. During the last 30 minutes, uncover to let the top brown slightly.
7. Serve individual portions with a dollop of sour cream and optional toppings like avocado, diced tomatoes, or fresh cilantro.
