Crock Pot Potluck Pierogies With Sauteed Onions And Butter - cooking recipe

Ingredients

48 pierogies (I buy Mrs. T's, 48 pierogies will fill up a 5 qt crockpot)
16 tablespoons unsalted butter (1 cup)
1 large white onion, chopped
salt, to taste
pepper, to taste

Preparation

Place frozen pierogies in the crockpot.
In a medium saucepan, melt butter and fry onion on medium-low heat, until onion is golden brown.
Pour onion and butter over pierogies; add salt and pepper.
Cook, on high, for 3 hours.
A few times during cooking, use tongs and gently re-arrange pierogies and ladle butter sauce to cover pierogies on top.
Turn to low or keep warm once pierogies are cooked and/or butter sauce begins to bubble.
