Description
This 4-Ingredient Slow Cooker Pierogi Casserole is the ultimate comfort food for busy days. Frozen pierogi are combined with smoky kielbasa, a creamy sauce, and melted cheese, then slow-cooked to perfection. The result is a rich, hearty, and cozy dish that tastes like it took hours of effort—when in reality, your slow cooker does all the work. It’s perfect for weeknight dinners, family gatherings, or anytime you crave something warm and satisfying with minimal prep.
