Frozen pierogi form the base of this delicious casserole that's deceptively simple to make. In the recipe below, a combination of bacon and onions are fried before being tossed with butter, sour cream, and, of course, pierogies. Spread in a casserole dish and topped with cheese, the pierogi are baked and topped with fresh green onions and a few more dollops of sour cream for a truly comforting meal.
Different pierogi can be used in this dish, from classic cheese to chicken to funky sauerkraut. The best part? They don't have to be defrosted ahead of time, making this the ideal last-minute dinner idea for days when the cupboards are a bit bare.
