  • 1 9x13 inch baking pan


  • 20 frozen pierogies
  • 1 tablespoon olive oil
  • ½ large onion chopped
  • ½ bell pepper chopped
  • 1 cup mushrooms sliced
  • 3 mild or hot Italian sausages
  • 10 oz cream of mushroom soup
  • ¼ cup whole milk
  • 1 ½ cups cheddar cheese grated


  • Preheat oven to 350°F.
  • Place frozen pierogis in one layer at the bottom of a 9x13 inch baking dish.
  • Heat oil in a frying pan over medium heat. Add onion, pepper and mushrooms to the pan and saute. Place vegetables over frozen pierogies.
  • Using the same frying pan, cook sausages that have been removed from their casings, breaking them down while cooking. Layer sausage in casserole dish.
  • Measure out milk into a measuring cup. Add the can of mushroom soup to the milk and whisk to combine. spread over top of the casserole ingredients. Top with cheddar cheese.
  • Bake in preheated oven for 35 minutes. Leftovers will keep for 3 days.


  • Use any flavour of pierogis you like. I used potato and cheese for this recipe, but use whatever you prefer. Any option would work well in this recipe!
  • Do you like making your own pierogis? Freeze 20 ahead of time for this recipe.
  • Instead of sausage, try bacon, pepperoni or cooked chicken.
  • Use different soup variations - cream of chicken or cream of bacon would work well.
  • Instead of cheddar cheese, try montery jack or mozzarella (pizza pierogi casserole!?!).
