• The sauce for this crockpot pierogi and kielbasa casserole looks thin when it comes out of the slow cooker, but it will thicken nicely as it cools.
• Adding crispy fried onions as a garnish if you make this in a Crockpot, or added at the last five minutes of baking, add a nice crunch to the casserole.
• You can store in the fridge for up to 4 days, but it does not do well in the freezer. The dairy takes on an odd consistency, so I do not recommend freezing. That was a sad thing for me but thankfully it is not a difficult or time-consuming dish.
