Favorite Sweet Potato Casserole

Sweet Potato Casserole Recipe

by Alli

For as long as I can remember, Sweet Potato Casserole has been one of my favorite Thanksgiving Day side dishes. When it comes to Thanksgiving, I like the side dishes more than the turkey. 

Of course, just any sweet potato casserole won’t do. Hold the marshmallows, please! Don’t come near my sweet potatoes!

How to Make Lightened Up Sweet Potato Casserole

When I was a little girl, mama always served Sweet Potato Casserole on Thanksgiving and other special occasions. When I would eat this casserole, I thought I was getting to eat dessert as part of my meal. 

The creamy sweet goodness of the potatoes combined with the sweet, buttery crunch of the topping – I’m in hog heaven (as grandpa used to say)!

Now that I’m wiser, my very favorite Thanksgiving side dish is much too sweet for my taste.

So I created my lightened-up sweet potatoes! For me, it has just the right amount of sweetness, crunch, and creaminess. It’s a hit!

My mouth is watering as I write this post! Maybe I need to make Lightened Up Sweet Potato Casserole tonight and not wait until Thanksgiving.

Favorite Sweet Potato Casserole

I like to bake the sweet potatoes for this recipe. Wash and dry the potatoes, pierce a few times with a fork and bake, unwrapped, at 400º for about 45-50 minutes or until tender.

In a large mixing bowl, mix together the sweet potatoes, butter, egg, milk, sugar, and vanilla. Pour into a greased casserole dish.

Mix the topping ingredients together and spoon over the potato mixture. Bake at 350º for 25-30 minutes.

Yield: 8 Servings

Helpful Hint: When I make Sweet Potato Casserole for Thanksgiving, I prepare the sweet potato mixture the day before, cover it tightly, and store it in the refrigerator overnight.

I also mix up the topping and place it in a ziplock bag and store it right beside the sweet potato mixture in the fridge.

On Thanksgiving Day, I remove the casserole and topping mixture about 30 minutes before baking. Top the casserole with the topping mixture right before baking.

Lightened Up Sweet Potato Casserole is my favorite side dish at Thanksgiving

A sweet potato casserole? WOW. That sounds so good. I have never had one before, but I am totally making one for Thanksgiving!

This recipe looks and sounds delicious. I really like that it’s a lighter, better for you option than the traditional sweet potato casserole.

I will be making this! I absolutely LOVE sweet potato casserole. I pig out on the one at Golden Corral. I really need to try and make it on my own.

One year I made Ruth Chris style sweet potatoes with the sugar/nut topping. It was so rich we couldn’t eat it. I love this version!

Jeanettte November 16, 2017 - 9:05 am

This is definitely something I need to make. I’ve been looking for a little bit lighter meals for Thanksgiving this year and this would be wonderful to add to it.

Always nice to lighten up a dish whenever we can. Sweet potatoes is the perfect dish to lighten up. Makes up for some of the heavier dishes we will be eating.

We love making a sweet potato casserole for the holidays! We like to make our own cranberry sauce and pour some on top!

Alli November 16, 2017 - 11:08 am

Yum! I’ve never thought of that.

Tomi C November 16, 2017 - 11:12 am

Sweet potato casserole is a must at our Thanksgiving dinner. That tip to prepare and store in the fridge overnight gives the flavors time to marinate and let’s that brown sugar and butter seep deep into those sweet potatoes. Yummy!

I love how you prepared the sweet potato, I would love to try that! The pecan is a great addition to it.

Sweet potatoes aren’t my favorite so I rarely make them. Hubby loves them though, and I know he would definitely enjoy this casserole.

I love sweet potato casserole. I have never tried making a lightened up version of it before.

I feel the same, I like the turkey but my favorite is all the sides lol. I love sweet potato casserole but like your recipe better. I will have to try it this way this year.

This looks tasty. We like traditional sweet potatoes with marshmallows on top but this sounds great.

I’m really liking this as a potential dish to go along with Thanksgiving dinner. The topping sounds awesome!
