Mashed Potato Casserole Mashed Potato Casserole

Author: Canadian Living

To minimize fuss on Christmas Day, you can make a potato casserole well ahead and freeze it, keeping in mind that freezing needs a richness to maintain the casserole's creamy texture. But if you're making it the day before or the same day, you can use the lightened-up variation.

In large pot of boiling salted water, cover and cook potatoes and onion until tender, about 20 minutes. Drain and return to pot briefly to dry completely. Mash until smooth; mix in cream cheese and butter until melted. Stir in cream, green onions, salt and pepper.

Transfer to 13- x 9-inch (3 L) glass baking dish or casserole; smooth top. (Make-ahead: Double-wrap with plastic wrap or foil and freeze for up to 1 month; or wrap and refrigerate for up to 2 days. Defrost in microwave. Or thaw in refrigerator for 24 hours; add 10 minutes to baking time.)

Bake in 400°F (200°C) oven until light golden and heated through, about 25 minutes, or in microwave at High, 10 to 12 minutes.
