Cheesy Perogies Casserole

I got this delicious recipe from my roomate Ashley in college who got it from her mom. Now, it's been so long since I've made it, the directions that follow are most likely going to need some tweaking. I never wrote it down so I'm a little fuzzy...

• Ready In: 1 hr 25 mins
• Serves: 6-8

Ingredients

• 1 (28 ounce) bag potato pierogies (I don't know the typical size of a medium sized bag of perogies, you can use any flavour)
• 1 (10 1/2ounce) can  cream of mushroom soup or 1 (10 1/2ounce) can  cream of celery soup
• 1⁄2 cup  cream (also, you may add some of a small tub of sour cream if you wish) or 1⁄2 cup milk (also, you may add some of a small tub of sour cream if you wish)
