For those of you who don't know pierogis are a type of dumpling with a potato filling. You can boil them, bake them or even fry them. I usually boil them then add butter and sour cream. Yumm.
Since I love pierogies so much I decided to try a casserole recipe. This is a homemade pierogi casserole, sort of a cheating way because you don't actually use pierogies.
I found this recipe on Food.com. Preheat oven to 350 degrees.
1 cup mashed potatoes (instant or leftovers is fine)
1 lb shredded cheddar cheese
3/4 cup butter
2 -3 medium onions, diced
9 -12 lasagna noodles
The first step is to boil the lasagna noodles.
