This Lightened Up Sweet Potato Casserole is My Favorite Thanksgiving Side Dish

Everyone has a favorite Thanksgiving dish, and it usually isn’t the turkey.

Yes, turkey is the centerpiece of the table, but it’s the side dishes that most of us look forward to the most. While some people are all about the mashed potatoes and gravy, I’ve always been a sweet potato casserole fan.

My family recipe for this casserole, while delicious, is loaded with sugar, butter, and evaporated milk.

But because roasted sweet potatoes are perfectly sweet on their own, I decided to start playing around with the recipe to find a lighter version of my Thanksgiving favorite.

Just a few simple changes make this lightened up sweet potato casserole a healthier option:

• Regular milk instead of evaporated
• Replaced brown sugar with pure maple syrup
• Decreased the amount of sugar
• Less butter

One ingredient that I didn’t change was including a beaten egg.

A Large Egg is the Secret to the Texture of this Lightened Up Sweet Potato Casserole

The key to a fluffy sweet potato casserole is a large beaten egg, as eggs provide structure and moisture.

One of the most common nutrition questions I get is about what kind of eggs to buy. And I don’t blame people – there are so many different labels and it can get confusing.

Which Kind of Eggs to Use

Personally, I choose Nellie’s Free Range Eggs as all their eggs come from healthy free range hens raised on certified humane farms.

Unlike some brands where the hens just spend less time inc cages, these hens are actually cage free – they don’t spend any time in a cage and have clean, well-ventilated barns to live in as well as ample space to roam around outside.

I also like that the hens are fed nutritious, high-quality feed free of antibiotics and added hormones, as a healthy diet for the hens means higher quality eggs.

A Good Sweet Potato Casserole Needs the Perfect Topping

In addition to an egg, the other key to this recipe is the oat streusel topping.

I know, no marshmallows, but I promise the oat topping more than makes up for it!

We aren’t big pecan fans, but if your family is, feel free to add a couple tablespoons of pecans (or walnuts) to the streusel topping.
