A healthy and lighter classic sweet potato casserole sweetened naturally  To be honest with you, I’ve never understood the whole marshmallow thing but after making this recipe, I totally get it! My favorite part of the whole thing was the topping! It’s the perfect mix of sweet and savory and the colors are just beautiful making it a wonderful addition to your Thanksgiving table. Some of my favorite Thanksgiving side dishes are Cranberry Pear Sauce, Green Bean Casserole and Brussels Sprouts Gratin.

How to Cook Sweet Potatoes for Casserole

I prefer to peel and cube my sweet potatoes before boiling until soft. You can also boil the potatoes whole until soft and then easily remove the skin after once cooled a bit. Then use a fork or potato masher to mash the potatoes until your desired texture. If you prefer them a silky consistency you can use an immersion blender, hand mixer or table top blender.

This recipe was adapted from a recipe for twice baked sweet potatoes in the White House Cookbook, Revised and Updated Centennial Edition (affil link) I picked up in DC. I made the recipe exactly as written, then tweaked it a second time to my taste, and to make it into a casserole (I just can’t leave a recipe alone).

The cookbook contains original recipes from the 1890’s along with modern low-fat versions of each recipe. If you’re a history buff, you’ll find this book amusing with tips on how to avoid a cold, wash feathers, or make dresses “incombustible” as well as early table etiquette tips from 100 years ago.
