This might be the ultimate comfort food casserole, made with frozen pierogies, kielbasa and a creamy cheese sauce. It preps in just 15 minutes, and tastes like a hug. Very filling & sauce is rich tasting.
This super simple homemade sauce is one of my favorites and is pretty much made in just onepan. A quick broil in the oven melts the balls of mozzarella and creates a super tasty parmesan crusted gnocchi. People this is a keeper.
*substitute all purpose flour for GF flour Lentil pierogi. My omni family loved these! Pro tip: you can make the filling ahead of time (we also gave it a zip in the food processor). And the pierogies freeze up great!
