- Finish the sauce: Remove the skillet from the heat, then stir in the cream of mushroom soup, sour cream, milk, cheddar cheese, and bacon.
- Assemble: Spread half of the sauce on the bottom of the prepared baking dish. Arrange the pierogis over the top, then spread the remaining sauce mixture over the top and add the chives.

Quick Tip
Depending on the size of the pierogis and your baking dish, you may have to shingle them to get them to fit. This is fine!
How to Store Leftover Pierogi Casserole
Store leftovers in an airtight container in the refrigerator for up to 3 days, or cover the baking dish with plastic wrap or aluminum foil. To reheat, place the casserole in a 350ºF oven for about 15 minutes, or until warmed through; you can also reheat it in the microwave.
Serving Suggestions
