This Slow Cooker Steak and Cheddar Potato Casserole is the ultimate comfort food, combining tender steak, creamy potatoes, and melted cheddar cheese. With minimal prep time and maximum flavor, this family-friendly recipe is perfect for a chilly evening or a convenient weeknight meal.
For best results, use Yukon Gold potatoes as they hold their shape well in the slow cooker. Searing the steak before slow cooking adds a significant depth of flavor. If you prefer a spicier casserole, add a pinch of red pepper flakes or a can of diced green chilies. Leftovers can be stored in the refrigerator for up to 3-4 days or frozen for up to 2-3 months. Reheat thoroughly before serving, adding a splash of beef broth if needed to prevent drying.
