This comforting casserole combines frozen pierogi, kielbasa, and cheese, slow-cooked to create a delightful meal that's rich in flavor and simplicity.
For added flavor, consider sautéing the onions and bell peppers before adding them to the casserole. You can also use a variety of cheeses or add crushed red pepper flakes for a spicier kick. If you prefer a crispy top, broil the casserole for a few minutes after cooking.
