- Sauté Aromatics: Add the chopped onion and garlic to the skillet with the beef. Cook for 2-3 minutes until softened and fragrant. Stir in the taco seasoning mix until well combined.

- Cook: Cover and cook on LOW for 6-7 hours or on HIGH for 3-4 hours, until the potatoes are tender.
- Add Cheese: Sprinkle the shredded Cheddar-Jack cheese over the top of the casserole. Cover and let it cook for an additional 10-15 minutes until the cheese is melted.
- Serve: Garnish with a dollop of sour cream and fresh cilantro leaves. Serve hot.
Pro Tips and Variations

Serving Suggestions
- Serve with warm tortillas or cornbread on the side.
- Pair with a crisp green salad or steamed vegetables for a complete meal.
Storage/Reheating
- Storage: Store leftovers in an airtight container in the refrigerator for up to 3 days.
