This 4-ingredient slow cooker pierogi is a true weeknight lifesaver. You literally dump frozen pierogi into the crock, add three simple ingredients, turn it on, and walk away. A few hours later, it tastes like you fussed with homemade dough and onions all afternoon. It has all the cozy Midwestern comfort of a church-basement potluck dish, but without the work, which makes it perfect for busy families or days when you want something hearty and hands-off.
