Party Potatoes

If you have been to my house much, you've probably had these. They are fantastic and a favorite of many. My mom made a bunch for us when she was here, so I thought I should share the recipe. very easy and verrryyy good :)
Party Potatoes

Prepare 12 servings of instant mashed potatoes according to directions
Add to mixture:
1 8 oz package of cream cheese (softened at room temperature)
1 C (or 8 oz) sour cream
1 1/2 tsp onion salt (which I can never find, so I do half garlic salt and half onion powder) if you find it somewhere tell me!

Blend until well mixed. Put into a greased large casserole dish. Top with small chunks of margarine and sprinkle with paprika. Refrigerate if not baking right away.
Bake at 350 degrees for 1 hour or until hot and bubbly. (can be less time if it's not coming out of the refrig.)
