This easy sausage & pierogi casserole is loaded with sausage, onions and frozen pierogis. It's covered with a creamy cheese sauce, and then baked to perfection.
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.
Notes
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!?!).
