🥘Ingredients
📝Ingredient notes
- Pierogis - You do not need to thaw the pierogis. They go into the dish frozen.
- Sausage - I use hot Italian sausage because I like a bit of spice. You can substitute with any other type if you prefer.
- Mushroom soup - Use any brand of cream of mushroom soup you prefer.
🥓Variations
- Instead of sausage, try bacon, pepperoni or cooked chicken.
- Like making your own pierogis? Freeze 20 of them to use in this recipe.
- 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!?!).
🔪Instructions
This easy pierogi casserole dinner takes 15 minutes to prepare, and only 35 minutes in the oven!
Preheat oven to 350°F and place 20 frozen pierogis in the bottom of a 9x13 inch baking dish. No need to grease the baking dish.
Heat oil in a frying pan and add bell pepper, onions and mushrooms. Cook on medium heat until the vegetables are soft and the mushrooms have been cooked through, about 5 minutes. Pour the vegetables over the pierogis.
Cook the sausage in the same frying pan used to cook the vegetables. You don't need to add in any more oil because the sausages will release fat as they cook. Break up the sausages while they cook. When they are done, scatter them evenly over the rest of the ingredients in the baking pan.
Measure out milk in a measuring cup. Empty the can of cream of mushroom soup into the measuring cup and whisk until combined. Pour over the top of the casserole and then scatter shredded cheese over top.

💭FAQs
You can cook the onions, bell peppers, mushrooms and sausage ahead of time. After they have cooked, combine them in a bowl and let cool. Cover and then store in the refrigerator for up to 3 days. When ready to make the recipe, layer the mixture over frozen pierogis and continue with step 5.
The milk and mushroom soup can be mixed together, covered and stored in the refrigerator as well.
Pierogi casserole can be frozen after the pierogi casserole has been assembled, and before cooking. Wrap in plastic wrap and then aluminum foil and freeze for up to 3 months. This can be put into oven frozen. Cooking time will probably be a little longer though.

Nina
Thanks for the review! Yes, definitely grease the baking dish. I'll add it to the recipe. 🙂

Love this recipe, just meal prepped one for the freezer as I’m about to have a baby.
How long to cook in oven from Frozen do you guess?
Thank you !
Nina
Congratulations!!! I would suggest thawing it overnight in the refrigerator instead of cooking in from frozen. 🙂
Colleen
Added andouille, celery ,peppers , and Cajun seasoning. My husband loved it and it came together really nicely.
We will have this one again.
Nina
I'm so glad your husband loved it! 🙂

My sister found this recipe and loved it so shared it with me and her daughter. We have in turn shared it with friends. It’s always a hit. I use Johnsonville mild Italian sausage meat, 2 sm-med peppers, half a large onion and a bit of garlic. I cook the meat first, set aside and then cook the veg in the sausage oil. Might as well use up all that flavour! (I drain any excess grease.) I add smoked paprika, lots of pepper and sometimes other seasonings to the soup mix. Once done, I sprinkle on fresh chopped green onions. So good!
Nina
I'm so happy you all love it! I love your variations!!!
