This is a creamy filling made with onions, mushrooms, sauerkraut and sour cream that you can use to fill pierogies.

In all the years I have been making Pierogi, I have never put sour cream in the filling. You can use mashed potatoes to hold the filling together. It makes it easier to work with. - 06 Sep 2004 (Review from Allrecipes US | Canada)
I always add brown sugar to this (about 2 T, or more, depending on your own taste). It cuts the tartness of the sauerkraut, and really make the filling. - 27 Oct 2007 (Review from Allrecipes US | Canada)
These were AWESOME!!! I love sauerkraut and just had to try these. 1/4 of the pierogis I boiled then fried and 1/4 of them I just fried. Hubby liked the boiled one but I liked just fried. I used a sour cream, lemon juice, garlic powder, onion powder, and dill weed dipping sauce. - 19 Aug 2008 (Review from Allrecipes US | Canada)
